At the market, I looked at who was selling what. Some grandmothers had really top-notch potatoes and other vegetables. When I asked how they managed it, everyone was silent. Only one said she used the "Confidor Extra" product—her son taught her. I bought this product. My impressions: it’s good mainly for potatoes and tomatoes against Colorado beetles and various sucking pests; for open-field cucumbers—I used it both in greenhouses and outside; it provides almost a month of protection, then you repeat; the first day after treatment, the beetles fall—it's very strong; it’s low in toxicity and usually just one treatment is enough for some crops; it works in hot weather. Overall, I can recommend it.
