Fenbutatin oxide temperature-sensitive organotin acaricide that inhibits nerve tissue. It is highly toxic to fish and other aquatic organisms, and is low toxic to birds and bees. It is safer to prey on mites, insectivorous ladybirds, and lacewings. High acaricidal activity, mainly contact killing, strong killing power to young mites, adults and nymphs, little killing power to mites eggs, no interaction with harmful mites that are resistant to organophosphorus and organochlorine insecticides Drug resistance.
application:
Fenbutatin oxide can be processed into dosage forms such as wettable powders and suspensions. It can be used in crops such as fruit trees, tea trees, flowers and other crops to control citrus spider mites, citrus rust mites, apple spider mites, tea orange gall mites, tea short whisker mites, chrysanthemum spider mites, rose spider mites, etc. It is used for citrus, grape and other fruit trees and ornamental plants to prevent and control plant mites in various active periods. Rat oral LD50 is 2630mg/kg. It is relatively non-toxic to bees and toxic to fish. Organotin acaricide. It has good control effect on plant spider mites, gall mites and rust mites, and has good activity on young mites and adult mites. It mainly has contact killing effect, has long residual effect, no systemic effect, and has poor effect on eggs.
It has no interaction with organophosphorus-resistant harmful mites and is safe for crops and natural enemies. When used at high temperature, the effect is good. It can be used to control spider mites in citrus, apples, pears, grapes, tea trees, beans, eggplants, melons, tomatoes and other vegetables. It can also be used to control edible mites on ornamental plants. For example, for the prevention and control of citrus red spiders, spray with 2000% to 2500 times of 50% wettable powder, and 2000 times of rust mite spray, which can cure both spider mites and rust mites.
Use 50% wettable powder to spray 1000 to 1500 times liquid for hawthorn and apple red spider, 1500 to 2500 times liquid for spider mites of eggplant, beans and other vegetables, and 1000 to 1500 times liquid for tea tree short hair mites and orange gall mites spray.
