Problems solved by technology

[0005] However, there are some technical defects in these existing technologies, which cannot meet the needs of current agricultural production. Therefore, it is necessary to develop new insecticidal compositions for the efficient control of rice and vegetable pests, which is of great significance for promoting the development of large-scale agriculture.

Abstract

The invention relates to an agricultural insecticide composition containing insect sulfamide (HY366) and thiamethoxam and application thereof. Insect sulfamide (HY366) and thiamethoxam are mixed and prepared according to the weight ratio of (1-100):(1-100), and an obvious synergistic effect on preventing and controlling rice plant hoppers and corn agrotis ypsilon harmful insects is achieved. The insect killing effect is improved, insecticide use cost is reduced, environmental pollution and pesticide residues are reduced, and pest resistance to insecticide can be overcome and delayed. The agricultural insecticide composition can be applied to vegetables to prevent and control plutella xylostella, asparagus caterpillars, cabbage caterpillars and other lepidoptera pests. The agricultural insecticide composition has no harmful effect on experimental crops, the leaf color and growth vigor are both normal, good safety is achieved, and the requirement for the safety of a pesticide preparation is met.

Description

【Technical field】 [0001] The invention belongs to the technical field of pesticides. More specifically, the present invention relates to an agricultural insecticidal composition containing thiamid and thiamethoxam, and also relates to the use of the agricultural insecticidal composition. 【Background technique】 [0002] Lepidoptera pests represented by cabbage caterpillar, diamondback moth, and beet armyworm are important pests of vegetables in most areas of my country. These pests affect the normal growth of vegetables by eating the leaves of plants, and can also cause damage through boring (such as advanced Spodoptera litura and Spodoptera litura can bore tomatoes, green peppers, etc.), seriously affecting the quality and market value of vegetables. Chemical control is the main means of controlling the above-mentioned pests, but with the continuous application of chemical agents, the problem of resistance has become increasingly prominent. In the actual process of agricult...
