Chlorempenthrin is a new type of pyrethroid insecticide with high efficiency and low toxicity, which has good effect on mosquitoes, flies and cockroaches. It has the characteristics of high vapor pressure, good volatility and strong killing power, and the knockout speed of pests is fast, especially in the spray and fumigation.
Usage method
1. Cotton pest control
(1) Prevention and control of cotton bollworm: application of medicine at the peak of egg incubation, 10% bifenthrin cream 23 ~ 40ml per mu of water 50 ~ 60kg spray, 7 ~ 10d after the drug has a good insecticidal and bud protection effect. This dose can also be used to control cotton bollworm. The appropriate period for prevention and treatment is the second and third generation of egg incubation, and each generation is treated twice.
(2) Prevention and treatment of cotton leaf mites: If the mites are applied at the stage of occurrence, 10% cream 30 ~ 40ml per mu of water 50 ~ 60kg spray, residual period of about 12d, can also treat cotton aphids, bridge worms, leaf worms, thrips, etc. (such as when dedicated to the prevention and treatment of cotton aphids, the dosage can be halved).
2. Control fruit tree pests
(1) Prevention and treatment of peachworm: apply medicine at the peak of egg incubation, when the egg fruit rate reaches 0.5% ~ 1%, use 10% bifenthrin emulsion 3300 ~ 4000 times liquid spray. Spraying 3 to 4 times in the whole season can effectively control its harm, and the residual effect period is about 10d.
(2) Prevention and treatment of apple leaf mites: before or after apple flower, in the stage of adult and if mites occur, when each leaf has an average of 2 mites, apply medicine, and spray with 10% cream 3300 ~ 5000 times liquid. In the case of low mite mouth density, the residual effect period was 24 to 28 days. It can also be used to control leaf miners and red leaf mites on other fruit trees.
3. Control vegetable pests
(1) Control of white whitefly: In the early stage of white whitefly occurrence, the insect population density is not high.
(2) About the head/plant, the dosage is: greenhouse cultivated cucumbers and tomatoes with 2 ~ 2.5g effective ingredients per mu of 50kg spray on water, open cultivated with 2.5 ~ 4g effective ingredients per mu of 50kg spray on water, can effectively control its harm within 15d. When the insect population density is high, the control effect of the same dose is not stable.
(3) Prevention and treatment of aphid: apply medicine in the occurrence period, use 10% bifenthrin emulsifiable oil 3000 ~ 4000 times liquid spray, can control the harm, residual period of about 15d. This dose can also control a variety of leaf eating pests, such as cabbage worms, diamonds moth and so on.
