Abstract

The present invention discloses a kind of pesticide preparation containing saturated quinary heterocyclic compound and its use. The pesticide preparation contains saturated quinary heterocyclic compound as the effective component, solvent and surfactant. It is used for soaking seed of and spraying beet, water melon, tomato, chili, cucumber, etc. It has pesticidal activity, bactericidal activity and plant growth promoting activity, can raise the drought resisting and soline-alkali resisting capacity of plant, and possesses high efficiency, low toxicity, good environment compatibility and low cost.

Description

technical field [0001] The invention relates to a pesticide preparation containing a saturated five-membered heterocyclic compound and its application. Background technique [0002] In the development of agriculture and modern production, the environmental problems caused by the use of pesticides have attracted great attention. According to a data from the World Food and Agriculture Organization, the world's agriculture is facing the huge pressure of an annual increase of 70 million people, and the arable land is always limited. Therefore, the whole world is calling for more attention to improving the quality of the existing arable land and the output per unit area. There are many measures to increase the output per unit area of ​​agriculture, and the use of pesticides is one of the important measures. The use of pesticides can save labor, reduce the cost of agricultural products, and improve economic benefits. Pesticides play an important role in plant growth, regulation,...
