Abstract

The invention belongs to the technical field of pesticide compounding, and particularly relates to bifenthrin containing missible oil and an application thereof. The effective components of the bifenthrin containing missible oil are theta-cypermethrin and bifenthrin; and the weight ratio of the bifenthrin to the theta-cypermethrin is 10:1-1:10. The bifenthrin containing missible oil has a particular effect on prevention and treatment of tea tussock moths through the synergistic effect of the components.

Description

technical field [0001] The invention belongs to the technical field of compounding pesticides and insecticides, and specifically relates to an emulsifiable concentrate containing bifenthrin and its application. Background technique [0002] Bifenthrin [0003] Moderately toxic to humans and animals, highly toxic to fish. The acute oral toxicity LD50 to rats is 54.5mg / kg; the acute dermal toxicity LD50 to rabbits is greater than 2000mg / kg. No irritation to skin and eyes, no teratogenic, carcinogenic or mutagenic effects. It has low toxicity to birds, the acute oral toxicity LD50 to quail is 1800mg / kg, and it is greater than 4450mg / kg to wild duck. [0004] Density relative density (d25) 1.21. [0005] Stability It is stable to light and also stable in acidic medium. It is still stable after one year of storage at room temperature, but it will decompose in alkaline medium. [0006] Physical and chemical properties: The pure product is a white solid, the solubility in wate...
