What are the long-lasting pesticides for killing aphids?
1. Pesticides that have long-lasting effects on aphids include dimethoxylin and other drugs. This drug is a new type of pesticide compounded by dinotefuran and dinotefuran. It has the effect of killing stomach poison on contact. It has strong systemic conductivity, good quick-acting effect, and long-lasting effect. It has a good control effect on sucking pests such as aphids, whiteflies, rice planthoppers, thrips, and leafhoppers.
2. Pymetrozine has a unique mode of action, mainly affecting the eating behavior of insects. As long as aphids, planthoppers, whiteflies and other sucking pests come into contact with mephidrone, they will immediately produce a needle blocking effect and stop feeding, eventually leading to death from starvation.
3. Mephidrone has a control effect on both nymphs and adults. The drug can penetrate into plant leaves and lasts for more than one month. It is safe against the natural enemies of aphids and is an ideal agent for preventing and controlling resistant pests.
