Embodiment 1

[0094] Example 1 70% fentrazone·chlorsulfuron wettable powder

[0095] 30% of mefentrazone, 40% of chlorsulfuron, 4% of polycarboxylate, 2% of calcium salt of alkylbenzene sulfonate, 5% of Sapindus powder, and bentonite were added to 100%, and the mixture was subjected to jet milling to obtain 70 % Methazone · Chlorsulfuron wettable powder.

Embodiment 2

[0096] Example 2 80% fentrazone·chlorsulfuron wettable powder

[0097] 45% of mefentrazone, 35% of chlorsulfuron, 5% of polycarboxylate, 3% of sodium lauryl sulfate, 2% of saponin powder, and 100% of kaolin, the mixture is jet milled to obtain 80% of azole Oxazone·chlorsulfuron wettable powder.

Embodiment 3

[0098] Example 3 60% fentrazone·chlorsulfuron water-dispersible granules

[0099] Methazone 40%, chlorsulfuron 20%, sodium dodecylbenzenesulfonate 5%, sodium lignosulfonate 3%, urea 3%, polyvinyl alcohol 0.5%, white carbon black 5%, bentonite to 100%, to prepare 60% of mefentrazone·chlorsulfuron water-dispersible granules.

Abstract

The invention relates to a weeding composite containing carfentrazone-ethyl and sulfonylurea. The composite is mainly characterized in that the weeding composite contains 1-60% of effective ingredient A which is carfentrazone, 1-60% of effective ingredient B, accessory ingredient and other excipients, wherein the effective ingredient B is selected from chlorsulfuron, cyclosulfamuron and amidosulfuron and is prepared into wettable powder, water dispersible granules, suspending agent, microemulsion and emulsion in water. The weeding composite disclosed by the invention can be used for preventing and controlling annual weeds in a wheat field.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a herbicidal composition containing active ingredient A fentrazone and active ingredient B 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 best synergisti...
