Many gardeners plant potatoes, which have long become one of the staple foods. It is not at all difficult to grow it, however, the overseas guests of the Colorado, who are able to destroy all plantings in a short time, become an obstacle to a large harvest. Therefore, the processing of potatoes from the Colorado potato beetle must be carried out regularly and carefully, from the preparation of planting material to harvesting.

Colorado potato beetle and its food

After wintering underground, they begin to appear on the surface already when it warms up to + 10-14ºС, which in central Russia occurs in late April and early May. After that, adult females actively lay eggs on young, just sprouted potato sprouts.

The main food for the "colorados" is potato tops, which are eaten in large quantities by both larvae and adult beetles. Their development from eggs begins during the period when buds and flowers appear on the bushes, it is at this moment that the planting of unprocessed potatoes is most vulnerable and suffers from pest invasion.

If nothing is done at such a time, then the Colorado potato beetles are able to eat almost 80% of the green mass of the bushes, which will entail a strong decrease in crop yields.

On a note!

The danger of the Colorado potato beetle lies in its extraordinary voracity and high reproduction rate. One female during the spring-summer season can lay up to 500 eggs, from which fast-growing red larvae hatch, feeding exclusively on young potato leaves and flowers.

When to spray potatoes?

If you plan to treat it with various ones, then you need to know how and when to spray potatoes from the Colorado potato beetle. The optimal time is selected based on the type of vegetable:

• it is better to spray early potatoes when the first eggs laid by females appear, then again - after 10-14 days;
• medium and late varieties are sprayed with a large number of larvae and adult pests.

The optimal spraying time is dry and calm weather, with high humidity, the poisons will become less concentrated, which will reduce their effectiveness. In hot weather, processing is hazardous to health due to strong toxic fumes of chemicals.

You should also know the time when it is better to process potato bushes: these are morning hours until 9-10 and evening hours after 18, but you must also ensure that there is no dew or raindrops on the leaves.

During the mass period, it is not recommended, because during the formation of tubers, the plant is vulnerable to chemicals, and toxic preparations can destroy not only harmful, but also beneficial pollinating insects. Therefore, it is better to postpone processing until the end of flowering.

If the manual assembly of Colorado beetles at such a time is not successful, then you can use biological preparations that will do less harm to the crop and help protect the bushes from harmful insects.

Processing can be carried out at least 2-3 weeks before the start of the potato harvest, otherwise the resulting tubers will be harmful to health.

Ways to deal with the Colorado potato beetle

When choosing a means or method for treating potatoes from the Colorado potato beetle, you need to take into account the degree of damage to the bushes by larvae or adult insects, the vegetative period of bush development, the presence of flowers and the amount of time left before harvesting.

With a slight damage by pests to flowers and tops, it is recommended to use manual collection of beetles and other folk methods, with mass reproduction - it will not be possible to do without chemicals.

On a note!

You can eat potatoes after treatment with chemical insecticides only after at least 20 days. During this period, toxic substances break down into harmless chemical compounds, and the grown tubers become suitable for human consumption.

Many gardeners try, but use only herbal infusions or decoctions that are used to process bushes. They should be cooked just before spraying the potatoes, and always repeat the procedure, because. they do not affect eggs and larvae.

Popular methods and recipes against the Colorado potato beetle:

• dusting tubers with birch wood ash powder during planting;
• a decoction of horsetail and dandelion, which are taken in equal parts, pour water and bring the mixture to a boil, then you need to cool, strain and before splashing, dilute in a ratio of 500 g of decoction in a bucket of water;
• a solution of dry celandine plants: they are put in a bucket, then water is poured and heated to a boil, then the broth cools, it is filtered and added to a bucket of 0.5 liters for spraying;
• an infusion of 200 g of sifted wood ash and 200 g of fresh chopped wormwood is prepared with the addition of boiling water, leave for 3 hours, mix well and filter, then spray the plants with it;
• wood ash, well sifted, can also be used dry, regularly sprinkling potato bushes, which helps to get rid of Colorado potato beetles in a week;
• a decoction of 3 kg of tomato tops per 10 liters of heated water is prepared by boiling it for 30 minutes, then it is infused, filtered and diluted at the rate of 1:5 with the addition of 40 g of grated laundry soap;
• a solution of 100 g of dry mustard in a bucket of water, 100 g of 9% vinegar is added there, then you need to sprinkle potato bushes with it.

Biologicals

Biological preparations for processing potatoes are safe for the soil and destroy exclusively striped pests. Their active ingredients do not harm when exposed to air, water and young tubers.

Popular biologics:

• Bitobaxibacillin or Bicol - is available in the form of a powder or tablets containing spore-crystalline ingredients and an exotoxin. The maximum number of treatments per summer is 4 times. Before spraying, a solution is prepared at the rate of 40-100 g per bucket of water. The drug contains spores of bacteria that enter the intestines of larvae and beetles and begin to develop, paralyzing the nervous system and causing mutations in adults, they also infect their fellows. Beetles that emerged from poisoned larvae are not able to reproduce.
• - refers to bioactive drugs that paralyze insects after entering their body, which occurs 8-10 hours after potato processing. The death of larvae and adults occurs after 3-6 days. Its disadvantage is the absence of damage to the oviposition, which is why it is necessary to re-spray after the next generation appears. Minimum air temperature during processing: +18ºС.
• Agravertin is a bioinsecticide preparation containing Avertin N, which acts similarly to Fitoverm, the only difference is that it is possible to process potato tops at a lower air temperature - from +12ºС. It also protects against thrips, spider mites and other pests. Spraying should be done every 2 days at least 3 times.

Processing chemicals

Insecticides are rightfully considered the most effective in, because they contain potent poisons. Therefore, when choosing how to spray potatoes from the Colorado potato beetle, it is recommended to focus on proven and highly effective preparations.

The most popular chemical insecticides:

• - insect-fungicide, contains neonicotinoid imidacloprid, which does not depend on washing off by rain, because it penetrates into the green parts of plants and poisons pests after they eat the leaves. It has a protective effect and stimulates the growth of plants, acts within 2-4 weeks. Recommended for repeated spraying against the Colorado potato beetle, but no later than 20 days before harvest.
• - an insecticidal drug, available in several forms (suspension, granules, tablets, powder), which can be treated after planting when germination and before the flowering of potato bushes, has a detrimental effect for several hours.
• Destroy - a systemic contact agent containing imidocloprid, lambdacyhalothrin, is recommended for use in the northern regions, since it retains its properties at low temperatures.
• - includes insecticidal components cypermethrin and chlorpyrifos, which allow you to quickly destroy larvae and beetles in one spray.
• Confidor Extra - refers to the systemic insecticidal preparations of the latest generation, which have almost no effect on root crops.
• - an insecticide, the components of which (thiamethoxam, lambdacyhalothrin, etc.) not only destroy pests, but also feed plants due to the content of vitamins, it is recommended to apply every 14 days.
• As well as Bankol, Senpai, Decis, Karate, etc.

In order to properly spray potato tops, when preparing an active solution of each preparation, one should be guided by the attached instructions; it is impossible to exceed the dosage of the insecticidal agent due to its likely negative effect on the plant. During processing, wear protective clothing, a respirator, gloves, goggles. After spraying, wash your face, hands, clothes and shoes well.

In recent years, new potent drugs have appeared that are not used during the mass attack of the Colorado potato beetles, but. The uniqueness of these products is that toxic substances penetrate only into potato tops, eating which, larvae and adult pests are poisoned and die.

The duration of action of such funds is 45-50 days, during which potato bushes have time to grow up well, safely survive the period of flowering and the formation of young tubers. Caring owners can then decide what measures to apply to further eradicate adult Colorado potato beetles on potatoes, given the processing time and the upcoming harvest.

Benefits of preplant treatment:

• increasing the yield of bushes;
• the ability to protect plants from pests and diseases for a long time;
• reduction in the number of sprays;
• improving the quality of tubers and promoting a good preservation of the crop.

Funds are used in several ways:

• processing from a sprayer of planting material, spread out on a film, and then drying;
• soaking nets with tubers in the prepared solution, guided by the instructions for this preparation, then drying and planting;
• spraying with the preparation of holes or furrows with spread out planting tubers.

These drugs include:

• Prestige, Chameleon - insecticides for spraying planting tubers, suitable for medium early and medium late varieties, applied directly by spraying potatoes before planting them in the ground;
• , Cruiser - are used for dressing potato tubers of early varieties, the prepared solution can be used to process the decomposed planting material or add it to holes or furrows with potatoes.

In order to save potato bushes from Colorado beetles and get a good harvest, it is necessary to use all kinds of methods and means of control, from pre-planting to the destruction of numerous pests on adult bushes. The choice between folk recipes and chemical preparations depends on the degree of damage to plantings in the garden, as well as the capabilities and wishes of the owner.

Foliar feeding of potatoes is just as important as root feeding. All the nutrients that the plant receives from the leaf - it transfers to the tubers. As a result - increased yields, healthy plants and soil.

The absence of the Colorado potato beetle, aphids, potato moths is due to foliar spraying, because most of them live on the surface. Enough of the culture of enemies and underground - these are bears, wireworms, larvae of May beetles, nematodes.

Potato needs, growing features

A feature of growing tubers is that foliar feeding of potatoes is the main way of introducing nutrition for growing plants. The first portion of fertilizer is applied under the root.

Usually these are complex mixtures that give a good start for further growth. They are added when planting directly into the hole. You can use both organic substances and minerals bought at a garden store.

The sweet taste of tubers attracts underground pests. In hot weather, they are forced to seek water and shelter, so they penetrate the potato, causing it to lose its marketable appearance, and sometimes exposed to a fungal infection due to damage to the integument.

Video: How to feed potatoes

Fertilizers are applied three times during the growth and fruiting season. This allows you to protect the plants and save the crop. Spraying is carried out at a certain time. There are drugs that affect live insects. There are those that are needed for prevention, when pests have not yet laid eggs.

Carefully! After feeding potatoes in August, you need to wait a certain time, after which you can eat the tubers so as not to harm your health. Terms are usually indicated on the packaging with a toxic substance.

Early varieties consume more nutrition, because the weather conditions in the initial period are still unstable, there are often temperature changes. Plants are forced to eat more intensively in order to increase their immunity. In general, tubers per square meter take 20 g of nitrogen, 6 - 8 g of potassium, 9 - 10 g of phosphorus, trace elements - boron, zinc, manganese.

According to the experience of many gardeners, potatoes best perceive organic fertilizers in the soil - rotted manure, compost, wood ash. After fertilizing with organic matter, for two years it was possible to dig up to 10 buckets of young tubers planted from one bucket. This is due to the fact that manure has a balanced complex of nutrients.

Root and foliar top dressing - which is more effective

It is impossible to determine what is more effective - foliar feeding of potatoes or ordinary ones, since they have different goals. Roots are designed to increase soil fertility and provide initial nutrition to seedlings after germination. According to the sheet, fertilizers are adjusted if a deficiency of certain substances is detected. All nutritional deficiencies are determined by the appearance of plants.

• A lack of nitrogen causes yellowing of the leaves. In violation of nitrogen nutrition, the level of photosynthesis does not reach its maximum. Consequently, tubers cannot take in enough potassium and phosphorus to grow.

• Potash fertilizers are useful in tandem with phosphate fertilizers. They intensify the decomposition of each other and have the most beneficial effect. Without potassium, the foliage begins to dry at the edges, the photosynthesis process is disrupted, the tubers form and pour poorly

• The lack of phosphorus in plants is more pronounced on neutral and slightly acidic soils. Even with sufficient application of phosphate rock, superphosphates, the leaves turn purple, the root system does not form and the tubers remain small until harvest. Therefore, phosphorus must be applied with acidic fertilizers - potassium and nitrogen.

Nutrition for plants is provided by ready-made mineral mixtures and organic substances.

Chemical substances

Chemicals include industrial fertilizers. For example - nitroammophoska, azofoska, special mixtures for potatoes. Their dosages are indicated in the instructions and exact observance is required so as not to upset the balance of nutrients and not destroy the crop.

Foliar feeding of potatoes is more profitable to carry out those fertilizers that best absorbed through the leaves. One of these is carbamide - urea.

The substance is more intended for spraying than for root application. At the same time, carbamide helps to increase the immunity of the plant, inhibiting the reproduction of fungal infections and bacteria.

For foliar spraying 300 g of the substance is dissolved in a bucket. For processing, choose morning or evening time so that the fertilizer stays on the leaves longer. there is also a danger that the solution will cause leaf burns during the scorching rays of the sun.

It is worth pointing out one common mistake when growing potatoes. When spreading fertilizer on the soil surface, you can achieve a crop of green tubers. Why is this happening? Because the root system will reach for food and set fruits closer to the surface.

And exposure to sunlight causes photosynthesis in the underground part of the plant. From this, the tubers turn green and are not suitable for food. The conclusion is to lay nutrients at the level of the root system and not be lazy.

organic

Organic fertilizers can also be used for foliar feeding of potatoes. It can be infusions of ash or manure. The purpose of the activities is disease prevention and pest control.

To prepare an infusion of fresh manure, you need to take:

• a third of a bucket of manure;

• to fill with water;

• insist a week, stirring occasionally;

• dilute each liter with 10 liters of water.

Spray on leaves. For this purpose, an ordinary millet broom was previously used, since small particles of manure can clog the spray gun. You can also water the roots with this solution.

The ash solution for spraying potatoes is prepared as follows:

• 200 g of furnace ash pour 10 liters of water;

• insist 45 days .

To combat pests and fungal diseases, another recipe is more suitable:

• Boil 300 g of ash (approximately 1 liter jar) for half an hour in three liters of water;

• cool and strain;

• add grated laundry soap 50 - 100 g;

• dilute up to 10 liters.

Importance of foliar sprays

Since potatoes are grown in the same beds every year, very careful care is needed so that diseases that take root with the crop in the soil do not have a detrimental effect on the crop. In small areas it is difficult to follow the principles of crop rotation, so special attention should be paid to top dressing before and after the flowering period.

Foliar top dressing of potatoes during flowering with chemicals is not carried out, because the smell of pollen attracts bees and you can poison beneficial insects. Secondly, during the flowering period, the bushes are most vulnerable to chemistry.

How to feed potatoes before flowering

Before flowering, copper sulfate is used to control pests, and potassium nitrate in the form of a solution is used for nutrition. Urea is also suitable if potassium was added earlier. Superphosphate before flowering will enable the tubers to gain weight.

Foliar method before flowering can be applied nettle green manure. To do this, the ground part of the nettle is crushed, poured with water in a barrel and insisted for a week. The solution is filtered and sprayed with tops.

This technique provides plants with an additional portion of potassium and nitrogen.

Complex top dressing during the flowering period of potatoes

How to feed potatoes during flowering, so as not to harm and at the same time not to lose the crop. It is recommended to use folk remedies for spraying:

• onion peel;

• walnut leaves;

• tobacco;

• poplar leaves.

Complex mineral dressings are applied under the root.

It is safer and more efficient to use fertilizers designed for a specific crop - there is minimal risk of overdoing it with dosages.

Folk recipes

Nicotine persecution of the Colorado potato beetle is carried out with a solution that is prepared as follows:

• 10 packs of unfiltered cigarettes domestic production clear of paper;

• pour 10 liters of water;

• insist 3 - 4 days;

• add grated laundry soap - 50 g.

Spray foliage from the invasion of beetles and slugs.

Onion peel contains phytoncides that repel pests of agricultural plants. In a small amount, the substance contains phosphorus, trace elements, vitamins. To prepare a decoction you need:

• 2 handfuls of onion scales;

• 10 liters of water.

Boil for 5 - 10 minutes, strain. Use as soon as it cools down. A sour solution will not do any good.

An infusion of walnut leaves has the ability to fight fungus and pathogenic bacteria.

During the flowering period, potatoes can be sprayed with walnut water:

• a third bucket fill with green leaves;

• fill with water and insist 3 - 4 days.

The period of formation and maturation of tubers

The period of formation and maturation of tubers is the most costly in terms of nutrient consumption. At this time, you need to ensure the power supply "from all sides". On the one hand, tubers gain weight and pull potassium and phosphorus from the soil. On the other hand, soil pests that damage potatoes are activated. Therefore, attention should be paid to both root and foliar top dressing.

The Colorado potato beetle is one of the most malicious opponents of every gardener. Vegetable growers process tubers and potato plants several times throughout the growing season, but they often fail to achieve the expected results. Insects continue to destroy plants, and the crop from frequent spraying accumulates many toxic substances. Therefore, many prefer to use exclusively folk remedies to protect potatoes from insects.

A set of preventive actions

The fight against potato pest will be much more effective if it is carried out throughout the year, and not limited to the growing season of the crop. It is important to constantly create conditions on your site that are unfavorable for the development and reproduction of insects. For each season there is a certain set of preventive actions.

Fresh or rotted walnut leaves are good at repelling pests. In the fall, they need to be scattered throughout the site, and then dig up the garden. Plowing the land on the eve of a cold snap will make it possible to destroy a significant part of the insects, which did not have time to go deep enough in preparation for wintering. Throughout the winter, it is necessary to scatter evenly on the garden bed, which has a detrimental effect on leaf beetles and enriches the soil with useful vitamins (phosphorus, potassium).

In the spring, before germination, several pieces of raw potatoes or their peel should be placed in glass jars (0.5 -1 l). Vessels must be buried flush with the surface of the soil, evenly distributing them throughout the garden. Periodically, such traps should be checked and pests that have fallen into them should be destroyed. It is possible to lure and collect insects by this method even after harvesting.

During the growing season, it is necessary to periodically inspect the tops, and in a timely manner to manually assemble and destroy pests. In addition to the pests themselves, their larvae must also be removed. And if the beetles on the potatoes are visible quite well, then finding the eggs is sometimes not easy. Insects usually debug them on the inside of the leaves.

Newborn cubs are much more dangerous than old individuals. They are able to destroy a large area of ​​plants in just one day. Therefore, it is important to prevent their occurrence as much as possible.

Dusting potato protection

This old folk remedy for the Colorado potato beetle, with frequent use, can have quite a positive result. Shedding tops and row spacing received a second name - "dry fight", which includes the following methods:

• Dusting of leaves with sown wood ash at the rate of 10 kg per one hundred square meters. The most effective is pine and birch ash.
• Cornmeal tends to expand in volume when exposed to moisture. Once in the stomach of an insect, it begins to swell strongly, which causes its death.
• The smell of fresh pine or birch sawdust scattered between the rows is well repelled by leaf beetles.

When dusting, it is not the quantity of materials used that is decisive, but the frequency of the procedure!

Spraying potatoes with infusions and decoctions

There is a wide variety of solutions for the preparation of which natural raw materials are used. Processing potatoes from the Colorado potato beetle with such infusions will help to significantly reduce its population in the garden.

How and with what to spray potatoes is a purely personal matter for every vegetable grower. Many gardeners add sunflower oil, vinegar, mustard, and other specific ingredients to their solutions. Regardless of the composition, there are a number of rules and recommendations for the treatment of garden crops with liquid preparations:

• Any of the solutions must be filtered before use to avoid clogging the nozzle of the spray device.
• Spraying should be carried out in calm weather in the early morning or evening (drugs quickly lose their insecticidal properties from exposure to sunlight).
• Adding soap or washing powder to the solution improves its adhesion to the surface of the leaves.
• Despite the natural origin of the components of the product used, it is necessary to work with it observing all safety measures.

A tool created on their basis is considered very effective for processing potatoes from Colorado potato beetles. Approximately half a liter jar of insects should be placed in 10 liters of water, covered with a lid. After 5-7 days, the solution will be saturated with the necessary toxins, and the "rodents" will settle to the bottom of the vessel. A liter of such an insecticide is diluted with two liters of water.

Spraying potatoes with undiluted infusion can burn the tops!

Neighbors that the "striped" does not tolerate

Colorado potato beetles have well-developed scent receptors, so they do not like to live in areas where strong odors predominate. To create such conditions in their garden, some vegetable growers alternate potato rows with plantings of other crops. Among the most "unloved" pests are onions, beans and beans. Some plants emit a sharp aroma only when flowering. It is customary for them to plant potato plantations along the perimeter. Calendula, coriander, violet and hemp have good deterrent properties. True, the cultivation of the latter is prohibited by law.

Features of pest control

Colorado leaf beetles are very thermophilic, they prefer to lay their larvae in well-lit and sun-warmed areas. It is noticed that in shady places the tops are devoured by insects much less. The pest also ambiguously applies to different varieties of potatoes. First of all, beetles eat bushes of early crops, the leaves and stems of which are usually not powerful enough.

In order to get rid of beetles on potatoes, it is advisable to use several methods overnight. The pest tends to adapt to certain drugs and conditions, so you can’t be limited to one specific method, no matter how effective it would be.

The fight will be much more effective if you destroy insects not only in your area, but also in the largest possible radius from it. Therefore, in such matters, it is important to interact with the owners of neighboring plots, share knowledge and experience, look for common solutions on how to get rid of beetles on potatoes, and carry out all “anti-Colorado” operations in the same time frame.

How to get rid of the Colorado potato beetle folk remedies - video

Many novice gardeners and farmers are interested in the question: when can you spray potatoes from the Colorado potato beetle. Many factors affect this event, namely: the variety of vegetable, weather conditions, the type of poisonous agent, and so on.

There are general recommendations from experts when to spray potatoes from the Colorado potato beetle. Agronomists advise starting procedures as soon as the pest lays eggs on the leaves. The interval between bullying is recommended to be set at 22-28 days. In general, processing times are set individually depending on the type of pesticide.

Spraying and variety of potatoes

It is advisable to spray the middle and late varieties of the culture with the mass appearance of beetles on the culture. Early potatoes are processed at the first eggs seen. Re-baiting is best organized a couple of weeks after the appearance of the larvae.

It is advisable to spray potatoes of any variety half a month before the start of collecting tubers. Otherwise, the vegetable can be harmful to health.

Dry weather without sharp gusts of wind are ideal conditions for haulm processing. At high humidity, poisons will be diluted with water. This reduces the efficiency several times. For the same reason, you should not spray in the very early morning and late evening hours after the appearance of dew. Very hot weather is a dangerous time to treat with chemicals. At the same time, poisons quickly evaporate and poison a person.

Processing during the flowering of potatoes

It is better to refrain from baiting beetles during the abundant flowering of potatoes.

Only manual assembly of pests is ideal. With the least harm to the crop, you can use the following drugs:

• Bicol;
• Fitoverm;
• Akarin;
• Bitoxibacillin;
• Agravertin.

These funds best cope with the first beetle larvae.

Why can't potatoes be treated for the Colorado potato beetle when flowers appear? During this important period, the plant actively forms tubers, and it is more vulnerable than ever to chemicals. In addition, toxic preparations can kill insect pollinators. Immediately after the inflorescences wither, you can begin chemical treatment.

What time of day to choose?

It is best to process potatoes before 9-10 o'clock and in the evening after 17-18. Spraying time depends on the temperature outside. Under such conditions, poisons quickly evaporate from the culture.

It is necessary to ensure that there is no dew or other moisture on the tops. When spraying, do not eat or smoke. It is advisable to use gloves, a mask and overalls. After the procedure, take a shower with soap, wash clothes and shoes with detergent.

Useful information about the Colorado potato beetle

The information below will help you better understand the behavior of the beetle and make the most effective spraying of potatoes from the pest.

• Exceptionally voracious insect. Able to eat the tops of the plant completely from the crown to the base.
• The beetle, in order not to remain hungry, can travel tens of kilometers.
• Food for the pest is not only potatoes, but also other nightshade plants.
• For one harvest, one to three generations of beetles appear. Therefore, chemical treatment must be carried out more than once.
• On cloudy days, as well as in the morning and evening, the insect likes to move around on the ground. The rest of the time can be spent in flights.
• In summer, striped pests can fall asleep for ten days. This is a kind of protection against lack of food.
• Quickly enough adapts to toxic chemistry. Therefore, it is advisable to use new means of struggle each time.

Summarize. Basic rules for spraying:

• Do not treat plants during flowering.
• Best time: morning and evening, before or after dew on the stems.
• Re-spraying should be done no earlier than 15 days later.
• Strictly observe the instructions on the packaging of the chemical.
• The last persecution must be carried out two and a half weeks before the collection of tubers.

When working with poisons, all safety measures must be followed. They are listed on the packaging. Do not neglect the dosage.

When to spray potatoes from a beetle?

A neighbor treats potato tubers from a beetle before planting with Taboo. Potatoes grow already with the content of a component that repels beetles. We refused such a tool. After all, it turns out that the plant is saturated with chemistry!

We prefer to spray potatoes with insecticides, when we find the first larvae - at the end of June.

This year we used the "Tan-rek" tool. The instructions for the preparation indicate that the time of death of insects is 2 days. A perfectly acceptable period.

What time of day is best to spray the Colorado potato beetle? We always process potatoes in the evening. And it’s not hot, and it’s easier for the plants.

Question: Is it possible to spray potatoes during flowering?

Our potatoes are starting to bloom, and just yesterday we processed them from the Colorado potato beetle. Nothing terrible happened - she is cheerful, she has not lost a single flower. We always do this and the potato harvest is always excellent.

How to spray potatoes from a beetle: our experience

And now in more detail how and with what to spray potatoes from the Colorado potato beetle, effectively and without unnecessary troubles.

We bought the Tan-Rek tool in one of the country stores. Price - 8 rubles per bag with an ampoule. It took 4 such ampoules for our area (total 32 rubles).

The agent was dissolved in a 20-liter canister with water.

For spraying, a garden pollinator "Beetle" was used. By the way, it is very convenient for them to spray plants from aphids, whitefly, weevil, to make foliar top dressing. Baba Tanya sprays potatoes from the beetle with another chemical agent - Intavir.

Folk remedies against chemistry: what else can you spray potatoes from the Colorado potato beetle

Birch tar: 100 grams diluted in 8-10 liters of water and sprayed every three days;

Onion peel: 200 g pour 10 liters of warm water, leave for 24 hours, spray potatoes;

Bitter wormwood: 200 g mixed with 1 glass of wood ash, pour 10 liters of hot water, leave for 6 hours;

Dusting with wood ash: spend in the morning, on dew. After a day or two, most insects die;

A decoction of celandine. The leaves are placed in a bucket, poured with cold water, boiled for 20-30 minutes. Then the broth is diluted in a ratio of 1 to 20;

Infusion of garlic. 1 cup chopped garlic and pour 10 liters of warm water, leave for 1 day;

Some plants repel the Colorado potato beetle. For example, if you plant garlic, beans or coriander, marigolds or nasturtium in the neighborhood, their smell can scare away beetles.
