Description
Technical field
The present invention relates to a kind of preparation method and application of agricultural chemical insecticide composition, specifically relate to a kind of insecticides containing Diacloden and emamectin benzoate and preparation method thereof and application thereof.This insecticides is applicable to the crops such as fruit tree, vegetables, cotton and Cereal and prevents and kill off various pests.
Background technology
Diacloden, English name: thiamethoxam, chemical name: 3-(the chloro-1,3-thiazoles of 2--5-ylmethyl)-5-methyl isophthalic acid, 3,5-oxadiazines-4-base fork (nitro) amine.Diacloden sterling is white crystalline powder, fusing point 139.1 DEG C, vapour pressure: 6.6 × 10-9Pa (20 DEG C), solvability (25 DEG C, g/L): water 4.1, organic solvent (25 DEG C, g/L): acetone 48, ethyl acetate 7.0, methyl alcohol 13, carrene 110, hexane >1mg/L, octanol 620mg/L, toluene 680mg/L.Diacloden belongs to nicotinoids high-efficient low toxicity insecticide, to insect, there is stomach toxicity, tag and systemic activity, can effectively prevent and treat Homoptera, Lepidoptera, coleoptera, Thysanoptera, wherein to the sucking pest special efficacy of Homoptera, as aphid, plant hopper, leafhopper, aleyrodid etc.Suitable for crop is rice class, beet, rape, potato, cotton, Kidney bean, fruit tree, peanut, sunflower, soybean, tobacco and oranges and tangerines etc.
Emamectin benzoate, English name: emamectin benzoate, chemical name: 4'-table-methylamino-4'-deoxidation abamectin benzoate.Emamectin benzoate sterling is white or light yellow crystalline powder, and fusing point is 141 ~ 146 DEG C, stable under usual storage requirement, unstable to ultraviolet light, is soluble in acetone, toluene, is slightly soluble in water, be insoluble to hexane.Emamectin benzoate is efficient, wide spectrum, lasting period length excellent pesticidal miticide, and the mechanism of action hinders the transmission of pest movements nerve information, causes insect health to be benumbed dead.The mode of action based on stomach toxicity, tag, to crop without interior absorption energy, but active ingredient can be infiltrated and used crop epidermal tissue, thus has the longer lasting period.To control Lepidoptera, mite class, coleoptera and homoptera pest have high activity, are widely used in the control of various pests on the crops such as vegetables, fruit tree, cotton.
Diacloden and emamectin benzoate all can be used for preventing and treating the insect on the crops such as fruit tree, vegetables, cotton and Cereal, but along with the increase of the medication time limit, the pesticide resistance of insect to single dose strengthens year by year, need increasing dosage and times for spraying just can reach insecticidal effect, which not only adds cost, environmental pressure also increases.Both compositions then have better insecticidal effect, and decrease drug use amount, reduce risk people and animals and pest natural enemy being produced to harm.
Summary of the invention
The object of the present invention is to provide a kind of Pesticidal combination containing Diacloden and emamectin benzoate, said composition for active component with Diacloden and emamectin benzoate, improves insecticidal effect, reduces drug use amount and access times, alleviate environmental pressure, there is good economy and environment protection significance.
