Embodiment 1

[0014] Example 1 In order to verify the insecticidal effect of different ratios of flubendiamide and emamectin benzoate on pests, different ratios of flubendiamide and emamectin benzoate were carried out For the indoor toxicity determination of diamondback moth, the corresponding concentration is formulated according to the weight percentage in the table, and the indoor control efficacy test is carried out to determine the co-toxicity coefficient and determine whether the effect is synergistic. The test results are reported as follows:

[0015] Table 1 Determination results of co-toxicity coefficient of flubendiamide and emamectin benzoate in different ratios

[0016]

[0017] The results of the measurement show that the compound medicament of flubendiamide and emamectin benzoate of the present invention composed of different ratios has a control effect test statistics on diamondback moth indoors, and the co-toxicity coefficient of the two compounds is greater than 20...

Abstract

The invention relates to a pesticide composition with synergistic effect, which has strong pest control function and is applied to chemical protection field of plants in agricultural industry; the pesticide composition is mainly used for preventing lepidoptera from damaging the crops such as rice, vegetables, fruit trees, cotton and the like, the pest control effect is good and the synergistic effect is obvious. The pesticide composition is different from other pesticide compositions, and is the pesticide composition with synergistic effect and is composed of two effective components:fipronil bisamide and emamectin benzoate, and the proportion of raw materials for preparing the pesticide composition are ass follows by weight percentage: 3-20 percent of fipronil bisamide, 1-10 percent of emamectin benzoate, 70-96 percent of additives. The pesticide composition is prepared into wetting powder or water content granular and is used for preventing lepidoptera from damaging the crops such as rice, vegetables, fruit trees, cotton and the like.

Description

technical field [0001] The present invention relates to an insecticide composition with synergistic effect, exhibits extremely strong insecticidal activity, is applied in the field of agricultural production phytochemical protection, and is used for preventing and controlling scale of rice, vegetables, fruit trees, cotton and other crops. The harm of Pteroptera pests has excellent insecticidal effect and obvious synergistic effect, and the insecticide composition is different from other existing insecticide compositions. Background technique [0002] Lepidoptera pests have always been the main pests in agricultural production. Lepidoptera pests harm almost all kinds of crops, affecting the yield and quality of agricultural products. At present, many Lepidoptera pests, such as diamondback moth, cotton bollworm, Spodoptera litura, Chilorrhizae, rice leaf roller, etc., are increasingly resistant to most pesticides, and conventional pesticides are difficult to control their dama...
