Abstract

The invention relates to a weed killing composition containing pyraflufen ethyl and sulfonylurea compounds. The composition is mainly characterized in that the pesticide composition contains 1-60% of effective ingredient A, 1-80% of effective ingredient B and the balance of auxiliaries. The effective ingredient A is pyraflufen ethyl, and the effective ingredient B is selected from tribenuron-methyl or thifensulfuron methyl. The composition can be prepared into wettable powder, water dispersible granules, microemulsions, emulsions in water, oil suspensions and suspending emulsions. The pesticide composition provided by the invention can be used for controlling weeds in wheat fields 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 metazafen and sulfonylurea compounds, which is used for preventing and controlling weeds in wheat fields and corn 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 p...
