Summary. Hello dear; Caterpillars are most afraid of insecticides and pyrethroid pesticides, such as 25% chlorpyramide, 20% pyrethrife, 20% bolluride, chrysanthemum emulsifiable concentrate, permethrin emulsifiable concentrate, deltamethrin emulsifiable concentrate, etc.

What pesticides are caterpillars most afraid of1, caterpillars are most afraid of pesticides, pyrethroid pesticides. For example, 25% chlorpyramide, 20% pyrethuron, 20% bollina, chrysanthemum emulsifiable concentrate, permethrin emulsifiable concentrate, deltamethrin emulsifiable concentrate, etc., must be operated in strict accordance with the instructions when using, and should not be used excessively. 2. Caterpillars have a certain degree of toxicity, if they come into contact with it, they will cause physical discomfort, and some caterpillars will also be highly toxic, such as highly toxic twelve points.

The larvae should be killed in time before they disperse, and the dispersed larvae can be killed by vibrating trees. Some chemical agents can also be used to control caterpillars, such as 80% dichlorvos EC 1500 times or Nongdile EC 2000 times, 90% trichlorfon crystals 1000 times, 50% phoxanthion EC 1000 times, 25% Ekkas EC or 50% metethion EC or 50% parathion EC 1500 times.

Caterpillars can be controlled with pyrethroid products. Generally, in the young larval stage, biomimetic preparations can be used for spray control, and the main agents that can be used are 25 chlorpyramide, 20 pyrethuron and 20 bolbolurea. When entering the advanced larval stage, you can choose to use low-toxicity, low-residue chemical agents for smoke spraying or spray control, and the optional agents are chrysanthemum emulsifiable concentrate, high-efficiency permethrin emulsifiable concentrate, deltamethrin emulsifiable concentrate, etc.
