Description

technical field [0001] The invention belongs to the technical field of pesticide compounding, and in particular relates to a compound composition containing sulfentrazone and its application. Background technique [0002] Farmland weeds are a type of biological disaster that seriously restricts sustainable agricultural production. At present, more than 1400 species of weeds have been discovered in my country, of which about 130 species are seriously harmful.
