Problems solved by technology

Due to the long development cycle and high cost of new pesticides, the compounding of existing pesticides can delay the occurrence of pest resistance, improve the actual control effect, expand the insecticidal spectrum and reduce the cost of pesticides. It is an important means of integrated pest control.
Spinosad and emamectin benzoate are currently the main pesticides for the control of rice leaf roller, diamondback moth and beet armyworm. It has been proved by experiments that the combined control effect of the two is better than that of a single drug. The compound oil suspension concentrate example of the two has not yet seen any report

Abstract

The invention belongs to the field of pesticide compositions, and in particular relates to an oil-suspending agent disinfestation composition which takes spinosyns and emamectin benzoate as effective components. The oil-suspending agent disinfestations composition is mainly applied to prevention and treatment of damages caused by insects including rice cnaphalocrocis medinalis, vegetable plutella xylostella, beet armyworm and the like. The oil-suspending agent disinfestations composition is characterized in that: (1) the composition comprises effective components of the spinosyns and the emamectin benzoate, and the rest components are acceptable auxiliary components which are allowed to be used in the pesticide; and (2) the mass proportion of the spinosyns to the emamectin benzoate is 1:50-50:1, preferably 1:4-4:1; and the effective components account for 1-50 percent, preferentially 2.5-35 percent, by weight percentage in the preparation. The oil-suspending agent disinfestations composition has the advantages that the drug characteristics are complementary to each other in advantages, and one drug can prevent and treat various kinds of crop insect damages so as to be convenient for farmers to apply the drug; the drug resistance of destructive insects are retarded, which is of significance to the resistance and the comprehensive treatment to destructive insects; and the composition has the advantages of synergy, favorable permeability, strong adhesivity, evaporation resistance, storage resistance and the like, reduces the dosage and improves the disinfestation effect.

Description

technical field [0001] The invention belongs to the field of pesticide compositions, in particular an oil suspension insecticidal composition with spinosad and emamectin benzoate as active ingredients, mainly used for paddy rice leaf rollers and Control of pests such as vegetable diamondback moth and beet armyworm. Background technique [0002] Spinosad is a low-toxic, high-efficiency, broad-spectrum, and low-residue insecticide. It has rapid contact and stomach toxicity to pests, and has a strong penetration effect on leaves, which can effectively control scale. Pests of the orders Diptera, Diptera and Thysanoptera. Suitable for use on vegetables, fruit trees, gardening, and crops. Emamectin benzoate (Emamectin benzoate, referred to as emamectin benzoate for short) is a new generation of high-efficiency insecticide, which has the characteristics of ultra-high efficiency, wide spectrum of action, no residue, and no pollution. It is effective against larvae and Many other ...
