The recipe for poison against the Colorado potato beetle at home
It is necessary to collect a full liter jar of adult Colorado beetles. Take a container of 20 liters, pour bugs there and fill with water, close the container. Beetles will die, but will still swim on the surface of the water. Over time, they will gradually sink to the bottom - wait 1 week. In a week, the poison will be ready, but in this proportion it will turn out to be highly concentrated (applying it undiluted, you risk burning potatoes). Pour the poison into 3 half-liter jars and dilute it with water: in the first half (1: 1), in the second - 1: 2, and in the third - 1: 3. Spray several bushes of potatoes from each can; after 24 hours, check the sprayed bushes and see what concentration is suitable for your potato variety. We used the poison freshly prepared; what happens to him during long-term storage (it intensifies or weakens) - we did not experience.
