Abstract

The invention relates to a herbicidal composition containing diflufenican and sulfonylureas. The herbicidal composition contains an active ingredient A, an active ingredient B, aids and other excipients, wherein the active ingredient A is diflufenican; and the active ingredient B is one of chemical compounds such as chlorsulfuron, cyclosulfamuron and amidosulfuron. The herbicidal composition is characterized in that: the active ingredient A accounts for 1 to 80 percent based on the weight of the herbicidal composition; the active ingredient B accounts for 1 to 60 percent based on the weight of the herbicidal composition; and the herbicidal composition can be prepared into wettable powder, water dispersible granules, a suspending agent, suspension emulsion, emulsion in water and micro emulsion and used for preventing and controlling weeds in wheat fields and has the characteristics that: the using amount of the herbicidal composition and pesticide residues are reduced, environmental compatibility is high, and the herbicidal composition is safe for people and livestock.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a herbicidal composition containing diflufenamide and sulfonylureas, which is used for preventing and controlling weeds in wheat fields. Background technique [0002] In recent years, the direction of pesticide development is to embody high efficiency, low toxicity, low residue and no pollution. The specific performance is the pursuit of "three highs", that is, (1) high safety, which not only requires low toxicity, low residue, and pollution-free; (2) high biological activity; (3) high selectivity. Therefore, continue to improve the performance of the current pesticide products to meet the requirements of high efficiency, low toxicity and no pollution. Therefore, choosing a compound mixture of pesticides has become the current first choice and an effective way. By adjusting the ratio of different pesticides, the pesticides with complementary properties can obtain ...
