FROM Colorado potato beetle - the real scourge of potatoes and eggplant every lover of gardening works on his site in the summer. Some summer residents are trying to get rid of pests by collecting them manually, while others use for this purpose chemicals. Many novice farmers are puzzled by the question of whether it is possible to stain a beetle when potatoes bloom.
Spray products
Chemicals (insecticides) are recognized as the most effective in the fight against Colorado potato beetles:
- To spray potatoes during the period of mass emergence of pests is effective Actellic. Has no less effective properties Aktara, the tool is used from the moment the first seedlings appear and until flowering.
- For repeated spraying of potatoes against Colorado potato beetles Colorado drug. It is used for every appearance of insects, but no later than 3 weeks before harvesting.
- Confidor Maxi is distinguished by the absence of negative effects on root crops.
Why you can not spray potatoes during flowering
However, experts do not recommend poisoning potatoes during flowering with all of the above drugs. This is explained by the fact that during this period, the culture becomes very vulnerable to pesticides, since it begins the active formation of tubers.
On a note!
It is undesirable to spray the culture during flowering and because the poisonous components can poison pollinating insects. Chemical treatment can be applied only before the formation of inflorescences and after flowering of potatoes.
What to do if beetles appeared on potatoes during flowering
Often gardeners are faced with the fact that when the potato begins to bloom, a lot of bugs appear on it. The ideal option in this case is to collect insects by hand. With a large accumulation of pests, potatoes can be processed during flowering only with biological preparations:
- Acarin;
- Bitoxibacillin;
- Bicol
- Agravertine.
It is preferable to carry out processing with the appearance of the pest in the larval stage. To achieve maximum effect after 7 days, repeated processing is carried out using folk remedies. To do this, often use:
- Wood ash. 0.5 kg of raw material is poured into 1 liter of water and brought to a boil. After a day, 50 g of laundry soap is added to the resulting infusion to enhance the fixing properties. The composition is adjusted to 10 liters of volume, after which they can be sprayed with plants from the Colorado potato beetle.
- Tobacco. So that young potato seedlings do not attack harmful insects, they must be sprayed with tobacco infusion. In 10 l of water, 0.5 kg of dried tobacco is insisted during the day, then laundry soap is added to the resulting composition.
- Tar solution , which is prepared by mixing 10 liters of water with 100 g of raw materials.
- Infusions of various plants (walnut, poplar, wormwood, etc.).
Is it worth fighting Colorado potato beetles after flowering potatoes
The question of whether chemical treatment is necessary after the inflorescence has fallen is one of the most frequently asked questions. Agronomists argue that in such a period insect attacks no longer pose a serious danger to the aerial parts of plants, due to the fact that from that moment the tops begin to wither gradually, and all the juices of the culture are sent to the development of tubers. And the use of pesticides, which subsequently accumulate in the tubers, will not bring benefits to human health.
