Pesticide composition and application thereof

Abstract

The invention discloses a pesticide composition and application thereof. The pesticide composition comprises active components, wherein the active components comprise a first active component and a second active component; the first active component is pyraclonil; the second action component is selected from one of amidosulfuron, cyclosulfamuron, flucarbazone, fluoroglycofen-ethyl and carfentrazone-ethyl; the weight ratio of the first active component to the second active component is 1 to (0.01-90). The pesticide composition has good application in control of weeds in crop fields. The activecomponents in the pesticide composition achieve synergy; after the pesticide composition is applied, the activity of the pesticide composition can be retained for a longer time, so that a good controleffect can be achieved by low application amount of the pesticide composition; the pesticide resistance of a variety of diseases can be delayed; the pollution of the pesticide to the environment is reduced; the pesticide composition is high in safety, can exert good control effects on a variety of diseases and can also achieve a positive effect on protection of the ecological environment.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a pesticide composition and its application. Background technique [0002] Rice is one of the main grain crops in my country, with a planting area of ​​about 33 million hectares, accounting for about 29% of the grain crop planting area. According to the geographical location and the characteristics of rice production, it can be divided into the southern rice area and the northern rice area. The important weeds in paddy fields are barnyardgrass, firefly rush, cow felt, bermudagrass, spinach, saponin, purple water amaranth, moshang vegetables, wild arrow mushroom, water chestnut, etc., which affect the yield and quality of rice. One of the main factors, if it is not controlled, will cause a large amount of rice production reduction, and the reduction rate can reach about 40%. [0003] Wheat is the main food crop grown in my country, including wheat (winter wheat and spring whe...

AI Technical Summary

Problems solved by technology

[0004] At present, the main herbicidal pesticide varieties used for post-emergence control of field weeds in rice fields and wheat fields have the disadvantages that their safety is greatly affected by environmental conditions (especially temperature and humidity conditions) and their drift is strong; and long-term single use of herbicidal pesticides leads to many The resistance of weeds in the field is growing rapidly, and if the amount of use is increased, the risk of pesticide damage to rice seedlings and wheat seedlings will be high; secondly, the cost of using existing weeding pesticides is high, and weeds are prone to relapse
