Embodiment 1

[0020] Take by weighing 45% flumesulam, 30% mesosulfuron-methyl, 2% sodium lauryl sulfate, 3% calcium lignosulfonate, 3% dispersant NNO (alkyl naphthalene sulfonate formaldehyde condensate ), kaolin added to 100% by weight. The above raw materials are pre-mixed, air-jet milled, and post-mixed through conventional methods for preparing wettable powders to obtain the 75% imazalam-methyl-sulfuron-methyl wettable powder.

Embodiment 2

[0022] Weigh 52% of flumesulfame, 18% of disulfuron-methyl, 2% of sodium lauryl sulfate, 2% of calcium lignosulfonate, 4% of polycarboxylate, and kaolin to add to 100% by weight. The above raw materials are pre-mixed, air-jet milled, and post-mixed by conventional methods for preparing wettable powders to obtain the 70% imazalam-methyl-sulfuron-methyl wettable powder.

Embodiment 3

[0024] Weigh 32% flumesulam, 18% mesosulfuron-methyl, 1% sodium lauryl sulfate, 3% polycarboxylate, 2% alkylnaphthalene sulfonate, light calcium carbonate and add to 100 % parts by weight. The above raw materials are conventionally prepared by the method of preparing water-dispersible granules, that is, pre-mixing, air-jet milling, post-mixing, kneading with water, granulation, and sieving to obtain the 50% imazulam-methyl-sulfuron-methyl water-dispersible granules .

Abstract

The invention relates to a mixed herbicide composition including mesosulfuron-methyl and flumetsulam. The herbicide composition employs mesosulfuron-methyl and flumetsulam as active ingredients, wherein the weight ratio of the active ingredients (flumetsulam : mesosulfuron-methyl) is 1:10-20:1. The herbicide composition has the advantages of low toxicity, weak sensitization, low poison to humans and animals, wide herbicide spectrum and significant synergistic effect for preventing and eradicating weeds, and is particularly suitable for prevention of various weeds in multiple crop fields, especially in wheat fields.

Description

【Technical field】 [0001] The invention belongs to the field of pesticide herbicides, in particular to a herbicide for preventing and controlling weeds in wheat fields, which is composed of compound (A) sulfaflufenacil and compound (B) methylsulfuron-methyl as active components Binary herbicide compositions. 【Background technique】 [0002] Weeds are one of the main factors that harm wheat production, and weeds must be controlled in order to increase the yield of wheat. In recent years, the reasonable selection of herbicides in wheat fields has become an important technical link to ensure the safe production of wheat. However, due to improper selection of herbicides or inadequate use of technology, the control effect is not satisfactory or the phenomenon of phytotoxicity occurs frequently. At present, there are few herbicide varieties that can control grass weeds and broad-leaved weeds at the same time. Usually, after people use a certain herbicide to control grass weeds, bro...
