Wheat seed treatment agent composition and application thereof

Abstract

The present invention discloses a wheat seed treatment agent composition and belongs to the technical field of pesticides. The wheat seed treatment agent compound comprises the active ingredients by weight percentage based on the composition: 1%-60% of imidacloprid or thiamethoxam, 1%-25% of avermectin or emamectin benzoate and 0.5%-25% fipronil. The wheat seed treatment agent composition disclosed by the invention is prepared from the three active ingredients, all of which have synergic effects compared with each of the three single dosages, and particularly has a remarkable synergic effect on prevention and treatment of wireworms. According to the wheat seed treatment agent composition, the amount of pesticides used in field can be greatly reduced, the insecticidal spectrum can be expanded, and the validity period is long. Main pests such as wheat aphid, heterodera avenae wollenweber and wireworms and the like in the growth period of the wheat through one-time seed dressing can be prevented and treated. The composition has characteristics of safety, high efficiency, low toxicity and labor saving, and can make a greater contribution to the production increment of wheat.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a wheat seed treatment agent composition. Background technique [0002] Wheat is one of the main food crops in China, but the yield and quality of wheat have always been threatened by pests, such as wheat aphids, cereal cyst nematodes and underground pests are important pests in wheat fields. [0003] Wheat aphids are frequent pests in my country's wheat fields, often causing starvation or failure of grains. At present, most of the pesticides used in production use nicotine and pyrethroids as active ingredients. The dosage forms are mainly emulsifiable concentrate and wettable powder. For spraying control, a wheat growth period generally needs to be sprayed 1-3 times, but the workload of spraying is large, and a large amount of organic solvents will be brought into the environment, which will cause environmental pollution and consume energy resources. Pesticide application will...

Problems solved by technology

[0005] Wheat will also be harmed by underground pests, especially wireworms can eat the roots of wheat throughout the wheat growing season, resulting in hollow seedlings, which have a great impact on crop yield. Generally, organic phosphorus such as chlorpyrifos and phoxim are used in production The dosage form of pesticides is mainly granules. The disadvantage of this dosage form is that the application workload is large, and after the active ingredients of pesticides are absorbed by solid particles, their mobility in the soil is poor, resulting in poor control effect; moreover, these agents are harmful to humans, animals, Poor environment and agricultural product safety

[0006] At present, there is no pesticide preparation that can control wheat aphids, cereal cyst nematodes and golden needles at the same time. In order to prevent and control pests and increase wheat production, farmers have to use pesticides many times, and even use highly toxic pesticides. The increase in intensity also poses a threat to the food safety of the people. In addition, with the increase in labor costs in recent years, the intensity of pesticide application labor has become an important factor considered by farmers when choosing pesticides. Therefore, it is urgent to develop a pesticide in agricultural production. A new pesticide formulation that is safe, easy to apply, and can control a variety of major wheat pests
