Problems solved by technology
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

The invention relates to a herbicide mixture of fenoxaprop-p-ethyl, quinclorac, bensulfuron methyl and pyrazosulfuron-ethyl, the herbicide can be used as haulm additive for rice field. By charging right amount of different excipient, the herbicide can be prepared into powder preparation, wet powder, water suspending agent, suspension emulsion, microcapsules, missible oils, granules, soluble granules and dispersible granules.
Description
technical field [0001] The invention relates to a herbicide, in particular to a combined herbicide which 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. Fenoxaprop-ethyl, quinclorac, and bensulfuron-methyl (or pyrazosulfuron-methyl) alone can only be effective against category 1-2 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 toxic...
