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
The present invention relates to a kind of agricultural herbicide, specifically, relate to a kind of Tefuryltrione of containing, fragrant phenoxy propionic ester (
Azoles acyl grass amine, cyhalofop-butyl), the herbicidal composition of two kinds of active components and application thereof.
Background technology
Tefuryltrione is the broad-spectrum herbicide of being developed by Bayer AG, and it is the three ketones weed killer herbicide, and it is to two oxidase (HPPD) inhibitor of hydroxyphenyl pyruvic acid.
Cyhalofop-butyl is unique kind that paddy rice is had tight security in the fragrant phenoxy propionic acid class weed killer herbicide.Cyhalofop-butyl also is interior suction conductivity weed killer herbicide, blade and leaf sheath by plant corpus absorb, the phloem conduction, accumulate meristem zone in plant corpus, suppress acetyl-CoA carboxylase, fatty acid is synthesized stop, the growth division of cell can not normally be carried out, film system etc. contains the fat structural deterioration, causes plant death at last.The cyhalofop-butyl speed of action is slower, generally needs for 1～3 week made weeds death.In the paddy rice body, cyhalofop-butyl can be degraded to the diacid attitude to the acetyl-CoA carboxylase non-activity rapidly, thereby cyhalofop-butyl has the safety of height to paddy rice.Because cyhalofop-butyl is degraded in water and soil earth rapidly, to succession crop safety.
Summary of the invention
The object of the present invention is to provide a kind of Tefuryltrione of containing, fragrant phenoxy propionic ester (
