Description

technical field [0001] The invention belongs to the technical field of herbicides, and in particular relates to a paddy field herbicide composition and its application. Background technique [0002] Weeds in rice fields have always been an important factor affecting yield. Among these weeds, barnyardgrass has the largest damage area, and there are also other types of sedges, bermudagrass, daughter of a thousand gold seeds, eye vegetables, and yujiuhua, etc. The damage area and severity are second, and Spirogyra is common everywhere , duckweed, firefly Lin, carp sausage, water sedge, water amaranth, water Polygonum, etc. At present, chemical weed control is the main means of controlling weeds. However, most of the paddy field herbicides on the market have the defect of narrow herbicidal spectrum. Using a single herbicide alone cannot completely and effectively control the occurrence of weeds in paddy fields, and excessive herbicide dosage or uneven application can easily ca...
