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
The invention belongs to the composite technical field of agricultural chemical insecticide, be specially a kind of missible oil that contains Biphenthrin and application.
Background technology
Biphenthrin
Medium to person poultry toxicity, very high to fish toxicity.To rat acute Oral toxicity LD50, be 54.5mg/kg; To rabbit acute dermal toxicity, LD50 is greater than 2000mg/kg.Skin and eyes are had no stimulation, without teratogenesis, carcinogenic, mutagenesis.To birds low toxicity, to quail acute oral toxicity, LD50 is 1800mg/kg, and wild duck is greater than to 4450mg/kg.
Density relative density (d25) 1.21.
Stability is stable to light, also more stable in acid medium, store at normal temperatures 1 year still more stable, but can decompose in alkaline medium.
Physico-chemical property: sterling is white solid, in water, solvability is 0.1mg/l, is dissolved in acetone, chloroform, carrene, ether, toluene, heptane.Be slightly soluble in pentane, methyl alcohol, former medicine is stablized more than 1 year at 25 ℃, stores at normal temperatures, and stability is greater than 1 year.At PH5-9 (21 ℃), stablize 21 days DT50-65-125 days in soil.
But its action effect is also very single, after large-scale application, resistance risk is also very high.
Beta-cypermethrin
English name: theta-cypermethrin

Effect feature: theta-cypermethrin is to belong to third generation pyrethroid insecticides, be mainly used in the control of the domestic hygiene insects such as the agriculture and forestry injurious insects such as field crop, economic crops, vegetables, fruit tree and vegetables, mosquito class bedbug and have that virus killing is efficient, wide spectrum, to people and animals' low toxicity, effect rapidly, the feature such as holding effect is long, have and tag and stomach toxicity, ovicidal, insect is had to the effects such as antifeedant activity, but all there is no systemic action.Resistance of rainwater washing against, has special efficacy to the insect that organophosphorous pesticide has reached resistance especially.Due to use for years, in addition with the cross resistance problem of organic phosphates, carbamates, make insect generally to such medicament, produce very strong pesticide resistance, preventive effect is not equal to before.
Summary of the invention
The object of the present invention is to provide a kind of missible oil that contains Biphenthrin and application, active ingredient is beta-cypermethrin and Biphenthrin, wherein the weight ratio of beta-cypermethrin and Biphenthrin is, Biphenthrin: beta-cypermethrin=10:1-1:10, especially good to control tea caterpillar, be mainly by the result of the synergistic function between each component.
Technical scheme of the present invention is:
A missible oil that contains Biphenthrin, active ingredient is beta-cypermethrin and Biphenthrin, wherein the weight ratio of beta-cypermethrin and Biphenthrin is, Biphenthrin: beta-cypermethrin=10:1-1:10.
As preferably, the weight ratio of beta-cypermethrin and Biphenthrin is, Biphenthrin: beta-cypermethrin=5:1-1:5.
The missible oil of beta-cypermethrin of the present invention and Biphenthrin, it consists of following component by weight percentage:
