Insecticidal composition

Abstract

The invention discloses a pesticide composition, which is characterized in that the composition comprises an active component of acetamiprid and carbosufan, the weight ratio of two active components is 1: (0.05 to 30).The pesticide composition has the advantages of being widely applicable to the crop plants such as grain crops, cereals, corns, cotton, vegetables, and fruit trees, having positive effect of preventing and curing the crop harmful sucking pests in the families of hemiptera, thrips, homoptera, and dipteral, such as pentatomid, thrips, cicada, leafhopper, plant hopper, whitefly, phylloxera, aphid, scale insect, wheatmidge, pachydiplosis oryzae, acarid, and the other pests, and demonstrating the significant synergistic activity, which is different from the prior other pesticides.

Description

technical field [0001] The invention relates to an insecticidal composition, which contains acetamiprid and carbosulfan as active components for controlling agricultural pests. technical background [0002] Acetamiprid is a pyridine insecticide with contact and stomach toxicity and certain systemic activity. Generally used in fruit trees, vegetables, melons, tobacco, potatoes, strawberries, tea trees, rice and other crops, it can effectively control aphids, leafhoppers, whiteflies, scale insects, etc. Its mechanism of action is unique, and the pests that are resistant to organophosphorus and pyrethroid pesticides also have good effects when using this drug. [0003] Carbosulfan is a carbamate pesticide, that is, a low-toxic derivative of carbofuran (carbofuran) pesticide. It is an efficient, safe, and easy-to-use systemic and contact insecticide and acaricide. It is a highly toxic pesticide One of the ideal substitutes for carbofuran. [0004] In recent years, crop yield ...

Problems solved by technology

[0004] In recent years, crop yield losses due to pests and diseases are increasing year by year. The current application of chemical agents is the most effective means to prevent and control agricultural pests and diseases. After the withdrawal of highly toxic pesticides such as methamidophos, some conventional pesticides such as imidacloprid have become the first choice for the prevention and control of agricultural pests. However, the field efficacy in recent years has shown that the long-term application of a single, repeated and dedicated application of an active compound to control pests in many cases leads to rapid selection of pests, that is, resistance, especially for common agricultural thorns. Suction mouthparts pests, such as rice planthopper, cotton red spider, etc., have developed some resistance to the current conventional pesticides (such as imidacloprid has developed greater resistance to rice brown planthopper), which directly leads to the control effect. reduce
