Abstract

The present invention relates to a herbicidal composition containing fentrazone, the composition is mainly characterized in that: the herbicidal composition contains 1-60% of active ingredient A fentrazone, 1-80% of active ingredient B, auxiliary agents and other excipients , The active ingredient B is selected from: dicamba, fluorfen, and metolachlor, and made into wettable powder, water dispersible granule, suspension, microemulsion, and water emulsion. The herbicidal composition of the present invention is used for controlling weeds in wheat, rice and corn fields.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a herbicidal composition containing mefentrazone, which is used for preventing and controlling field weeds. 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 best synergistic effect can be obtained from the pesticides with complementary pr...
