Buprofezin is a new type of selective insecticide that inhibits the growth and development of insects. It has strong contact and stomach toxicity. The mechanism of action is to inhibit the synthesis of chitin and interfere with the metabolism of insects, resulting in the death of the nymphs or the malformation of the adult wings. . Generally, it will be effective 3 to 7 days after application. It has no direct lethality to adults, but it can shorten the lifespan and reduce the amount of eggs laid, and most of them produce sterile eggs. The larvae die quickly even after hatching. Thiazinone has high selectivity, has a good control effect on the insects of Homoptera planthoppers, leafhoppers, whiteflies and scale insects. It also has long-lasting larvicidal activity against certain coleopteran pests and mites. Can effectively control planthoppers and leafhoppers on rice, tea, leafhoppers on potatoes, citruses, whiteflies on vegetables, shield scales and mealybugs on citruses, and can also control scale insects on fruit trees and tea trees Wait.
Instructions:
1. Control of rice pests:
① Rice planthoppers and leafhoppers: spray once at the beginning of the main generation of low-instar nymphs, use 20-30g of 25% wettable powder per mu (effective ingredient 5-7.5g), 5-10kg of water , Low-volume spray or constant spray of 40-50kg with water, focus on spraying the middle and lower parts of the plant.
② Thiazinone is used to control rice brown planthopper, in the main generation and its predecessors, from 25 to 30 g/mu of 25% wettable powder during the egg hatching period to the youngest nymph blooming period. (Middle and lower part of rice plant) Evenly spraying once each time can effectively control damage. Applying at the beginning of the peak generation of nymphs of brown planthoppers can also treat white-backed planthoppers and leafhoppers, and the effect can reach 81-100%.
2. Prevention and control of fruit tree pests: To control citrus echinococcus, in the peak period of young nymphs, use 25% wettable powder 1500~2000 times liquid (125~167mg/kg) to spray evenly, the effect is good.
3. Control of tea pests: to control tea green leafhoppers, black fly mealworms, white scales, tea orange gall mites, etc., in the non-plucking period of tea and the prevalence of young nymphs or nymphs and the high density of insect mites. 25% thiazinone wettable powder 750~1000 times solution (250~333mg/kg). When the density of insect mites is low, spray 1000-1500 times (167-250mg/kg) evenly to effectively control the harm of insect mites.
4. Thiazinone is used to control whiteflies in greenhouse cucumbers, tomatoes and other vegetables. In the peak period of young nymphs, 25% wettable powder 2000-2500 times solution (100-125mg/kg) is sprayed evenly, which has good control effect. And can cure tea yellow mites and so on.
