Abstract
The invention discloses a herbicide composition for preventing and eliminating weeds of a paddy field and a use thereof, in particular to a herbicide for preventing and eliminating grass weeds, broad-leaf weeds and sedge weeds in the paddy field. The herbicide is a three-element mixture consisting of metamifop, benzobicylon and methoxone. The weight ratio of metamifop to benzobicylon to methoxon in the composition is (1 to 15): (1 to 20): (2 to 60) and preferably 5:10:40. The compound herbicide composition is used for preventing and eliminating weeds of the paddy rice, and is reasonable in components, the prevention effect is better than the activity of each component used independently, the herbicidal spectrum of the weeds can be enlarged, the prevention cost can be reduced, the weed resistance can be retarded, the safety for crops is good, and the safety requirement of the pesticide preparation can be met.
Description
technical field [0001] The present invention relates to a compound herbicide composition for paddy fields, in particular to a herbicide for controlling gramineous weeds, broad-leaved weeds and Cyperaceae weeds in paddy fields. A ternary herbicide composition composed of bicyclic sulcotrione and dimethyltetrachloride as active components. Background technique [0002] Chemical weeding is one of the main means of controlling weeds in farmland in agriculture. In recent years, with the continuous use of many herbicide varieties in large areas of rice fields, many weeds have developed resistance, and the control effect is difficult to guarantee. Especially prominent, with the current conventional herbicides have been unable to control. Therefore, it is necessary to provide a paddy field herbicide to meet the usage requirements. [0003] Metamifop is an aryloxyphenoxypropionate herbicide, which belongs to the acetyl-CoA carboxylase inhibitor. The active ingredient can be quickl...
