Abstract
The invention belongs to the technical field of compounding pesticides, and specifically relates to missible oil containing emamectin benzoate and bifenthrin and an application of the missible oil. The effective components of the missible oil are emamectin benzoate and bifenthrin in a weight ratio of 20:1-1:1. The missible oil containing emamectin benzoate and bifenthrin is particularly beneficial to prevention and treatment of sphingid by virtue of synergistic interaction effects 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 emamectin-benzoate and 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.

Former medicine is white or light yellow crystalline powder; Fusing point: 141-146 ℃; Be dissolved in acetone and methyl alcohol, be slightly soluble in water, be insoluble to hexane; Stability: stable under the condition of conventionally storing.
Emamectin-benzoate is a kind of microbial source low toxicity Insecticidal and acaricidal agent, has the features such as activity is high, insecticidal spectrum is wide, compatibility good, the lasting period is long, use is safe, and the mode of action be take stomach toxicity as main, has action of contace poison concurrently.Its insecticidal mechanism is to hinder pest movements nerve.Not in fish pond, bee farm, mulberry field and around use, liquid does not pollute the waters such as pond.Poisonous to honeybee, in fruit tree, do not use flowering stage.The safety of general crop interval of gathering is 7 days.
But abuse makes insect generally produce very strong pesticide resistance to such medicament, 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 emamectin-benzoate and Biphenthrin and application, active ingredient is emamectin-benzoate and Biphenthrin, wherein the weight ratio of emamectin-benzoate and Biphenthrin is, Biphenthrin: emamectin-benzoate=20:1-1:1, especially good to control hawkmoth, be mainly by the result of the synergistic function between each component.
Technical scheme of the present invention is:
A kind of missible oil that contains emamectin-benzoate and Biphenthrin, active ingredient is emamectin-benzoate and Biphenthrin, wherein the weight ratio of emamectin-benzoate and Biphenthrin is, Biphenthrin: emamectin-benzoate=20:1-1:1.
As preferably, the weight ratio of emamectin-benzoate and Biphenthrin is, Biphenthrin: emamectin-benzoate=10:1-7:1.
The missible oil of emamectin-benzoate of the present invention and Biphenthrin, it consists of following component by weight percentage:
Biphenthrin 1-75%,
Emamectin-benzoate 1-10%,
Polyvinyl alcohol sorbitan monolaurate 2-10%,
N-butanol 1-15%,
Rapeseed methylester 1-5%.
As preferably, the missible oil of emamectin-benzoate of the present invention and Biphenthrin, it consists of following component by weight percentage:
Biphenthrin 70-75%,
Emamectin-benzoate 5-10%,
Polyvinyl alcohol sorbitan monolaurate 2-10%,
N-butanol 1-15%,
Rapeseed methylester 1-5%.
Wherein, the total weight percentage of described active ingredient is 75～80%.
As further preferred, the missible oil of emamectin-benzoate of the present invention and Biphenthrin, it consists of following component by weight percentage:

Emamectin-benzoate 10%,
Polyvinyl alcohol sorbitan monolaurate 10%
N-butanol 5%
Rapeseed methylester 5%.
The missible oil of emamectin-benzoate of the present invention and Biphenthrin, for preventing and treating beet armyworm, cabbage heart snout moth's larva, hawkmoth, is particularly useful for preventing and treating hawkmoth.
Beneficial effect of the present invention is:
Said composition is compounded cream composition, compare with single product, the feature with binary composition, strengthened significantly effect, delay the generation of pest resistance to insecticide, and expanded effective active control spectrum, and thering is speed fast, the lasting period is long, consumption is low, eco-friendly feature, the more important thing is, this compounded combination has effectively resisted the problem that pest resistance produces, farthest alleviated the problem of current pest resistance to insecticide, thereby reduced the consumption of agricultural chemicals, also alleviated the impact for environment, met the trend of future society environmental protection.The control efficiency of composition of the present invention is especially good to control hawkmoth, is mainly by the result of the synergistic function between each component.
To the compound synergic research of composition of the present invention, test adopts hawkmoth for test.
