Abstract

The invention provides a herbicide composition. The herbicide composition comprises the active ingredients of Tefuryltrione and metamifop or cyhalofop-butyl in a weight percent of 1:1,000-1,000:1. The invention also provides application of the herbicide composition in preventing and controlling annual and perennial broadleaf weeds and gramineous weeds in a rice field. Compared with a single dosage, the herbicide composition has the advantages of remarkable improvement of weed control effect, excellent synergy, reduction of the usage amount of medical preparations, reduction of medicament cost for farmers, reduction of the influence to the environment, expansion of weed control spectrum, and effective delay of the generation and development of single dosage resistance.

Description

technical field [0001] The present invention relates to a kind of agricultural herbicide, specifically, relate to a kind of containing Tefuryltrione, aryloxyphenoxypropionate ( mefentrazone, cyhalofop-ethyl), herbicide composition of two active ingredients and application thereof. Background technique [0002] Tefuryltrione is a broad-spectrum herbicide developed by Bayer AG. It is a triketone herbicide and is a p-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitor. [0003] Cyhalofop-ethyl is the only aryloxyphenoxypropionic acid herbicide with high safety to rice. Cyhalofop-ethyl is also a systemic conductive herbicide, which is absorbed by the leaves and leaf sheaths of plants, conducts in the phloem, accumulates in the meristem area of ​​plants, inhibits acetyl-CoA carboxylase, stops fatty acid synthesis, and promotes cell growth The division cannot be carried out normally, the membrane system and other lipid-containing structures are destroyed, and finally the plant d...
