Characteristics of the action of high-efficiency cypermethrin and what pests are controlled?

High-efficiency cypermethrin pesticides belong to the pyrethroid insecticide class, which is an isomer of cypermethrin, and its activity is much higher than that of cypermethrin. When controlling pests, it has a touch killing effect, stomach poisoning effect, can quickly kill pests, and has a good control effect on a variety of pests. And high-efficiency cypermethrin has no conduction and internal absorption effect in plants, and the control effect on lepidoptera and Coleoptera pests is better, and the drug has a longer shelf life, but the exertion of high-efficiency cypermethrin efficacy is greatly affected by temperature, and the efficacy is significantly improved with the increase of temperature, and the efficacy of temperature decrease decreases.

First, the main pests to be controlled

Inchworm, aphid, wood lice, spotted fly, leaf curl moth, caterpillar, thorn moth, heartworm, thrips, twill moth and other pests.

For the control of aphids, 4.5% high-efficiency cypermethrin can be used to add 40 kg of water to 50 ml and spray evenly.

For the control of green insects and small cabbage moths, it should be sprayed before 3 instar larvae, 4.5% high-efficiency cypermethrin 30 ml mixed with 40 kg of water, even spray.

To control leafminer moths, 2000 times of 4.5% high-efficiency cypermethrin was used at the peak of egg hatching, and evenly sprayed for control.

When controlling caterpillar and moth pests, before the 3-instar larvae, use 4.5% high-efficiency cypermethrin 4000 times liquid and spray it evenly.

To control thrips, 4.5% high-efficiency cypermethrin 50 ml can be mixed with 40 kg of water, and evenly sprayed for control.

Second, the commonly used dosage form of high-efficiency cypermethrin

The general dosage form of high-efficiency cypermethrin is 4.5% or 5% dosage form 1500 times or 10% dosage form 3000 times liquid, which is better in the early stage of insect infestation. Because highly potency cypermethrin is susceptible to temperature, it can be compounded with other pesticides to compensate for deficiencies, such as compounding malathion or methyl vitamin salts.

3. Precautions

Due to the poor conductivity and systemic properties of high-efficiency cypermethrin, the spray should be uniform and thoughtful.
