Butralin/pendimethalin and clomazone combined herbicide preparation

Abstract

The invention relates to pesticide, which in detail is a mixed herbicide with Pdibutalin, Pendimethalin and Imazethapyr. It is characterized in that it takes effective component of Pdibutalin, Pendimethalin and Imazethapyr to prepare mixed herbicide, adds proper amount of carrying agent or adjuvant to produce powder agent, wettable powder, water suspending agent, suspoemulsion microcapsules, missible oil, particle, soluble granule, dispersing granule and etc. The advantages of said herbicide are that it solves problem of no herbicide for dry rice field and enlarges weed removing range, it can control forage grass, perennial broadleaf weed and cyperus weed in the dry rice field, the herbicide consumption is dramatically reduced, and it is safe for crops in the field and the second stubble crops.

Description

technical field [0001] The invention relates to a herbicide, specifically a combined herbicide that has good control effects on grass weeds, broad-leaved weeds and sedge weeds in upland rice fields. technical background [0002] There are no herbicide registered varieties in upland rice fields in my country. Zhongbuling or pendimethalin and clomazone alone can only be effective against 1-2 types of weeds in the field. Therefore, when farmers weed weeds in upland rice fields, due to lack of knowledge about herbicides, they usually only buy one type of herbicide, which can only remove 1-2 types of weeds in the field, and other common types of weeds cannot be removed. Poor, affecting rice harvest. However, if farmers buy a variety of herbicides, it will increase the weeding cost per mu of upland rice fields and reduce agricultural income; at the same time, due to the increase in the application of herbicides, their environmental toxicity will also increase, resulting in incre...

Therefore, when farmers weed weeds in upland rice fields, due to lack of knowledge about herbicides, they usually only buy one type of herbicide, which can only remove 1-2 types of weeds in the field, and other common types of weeds cannot be removed. Poor, affecting rice harvest

However, if farmers buy a variety of herbicides, it will increase the weeding cost per mu of upland rice fields and reduce agricultural income; at the same time, due to the increase in the application of herbicides, their environmental toxicity will also increase, resulting in increased environmental pollution, which is not conducive to human health
