Mite-killing composition containing fenbutatin

Abstract

The invention provides a fenbutatin oxide containing miticide compound, which is pesticide. The w emulsifiable agent has the eight proportion constituents that: fenbutatin is 1.0-20 percent, ingredient B is 5.0-30 percent, silicone synergistic organ is 0.5-5.0 percent, emulsifier is 5.0-20 percent, and solvent is 35-80 percent. The wettable powder has the weight proportion constituents that: fenbutatin is 1.0-50 percent, ingredient B is 5.0-30 percent, assistant is 5.0-20 percent, and carrier is 30-80 percent. The ingredient B is dicofol or tetradifon. The invention has long effective duration, quick effect, and wide preventing spectrum; can kill the grown acarid, larval nymph, and acarid eggs; has strong touch killing function and long residual effective duration; the production cost of the product is low, the constituents have positive synergy effects with each other, and can delay the drug-resistance of acarid to occur.

Description

Technical field: [0001] The invention relates to pesticides, which is an acaricidal composition containing fenbutatin. Background technique [0002] In recent years, the rampant occurrence of mites due to the proliferation of mites induced by long-term use of copper fungicides has become a problem that cannot be ignored. Mite pests, commonly known as red spiders, are one of the main pests of fruit trees, cotton, vegetables and other crops. The citrus spider mite, also known as Panonychus citrus, is the number one pest in citrus production. The adult mites, nymphs, and young mites of this insect all damage the young shoots, leaves, flower buds, and fruits, and absorb the juice. The damaged leaves show countless small off-white spots, which lose their original luster. A large number of fallen leaves affect tree vigor and yield. There are many generations of mites in a year, and the population growth ability is strong. It is often necessary to apply pesticides several times ...

AI Technical Summary

Problems solved by technology

For a long time, due to the excessive amount of mixed acaricides with pyridaben as the main component, their control effect has decreased and resistance has been induced.
