Embodiment 1

[0025] Weigh 7.5% flufensulfuron, 12.5% ​​methyl disulfuron, 2% sodium lauryl sulfate, 3% calcium lignosulfonate, 3% dispersant NNO (alkyl naphthalene sulfonate formaldehyde condensate ), Kaolin is added to 100% by weight. The above-mentioned raw materials are pre-mixed, jet pulverized, and post-mixed through conventional methods for preparing wettable powders to obtain the 20% fluoxuron-methyl disulfuron-methyl wettable powder.

Embodiment 2

[0027] Weigh 12% flufluazasulfuron, 28% metsulfuron-methyl, 2% sodium lauryl sulfate, 4% calcium lignosulfonate, 3% TERSPERSE 2700, 2% sodium dibutyl naphthalene sulfonate, 3% white carbon black and kaolin are added to 100% by weight. The above-mentioned raw materials are pre-mixed, jet-pulverized, and post-mixed through conventional methods for preparing wettable powders, to obtain the 40% fluoxuron-methyl-disulfuron-methyl wettable powder.

Embodiment 3

[0029] Weigh 25% flurimsulfuron, 40% methyl disulfuron, 1% sodium lauryl sulfate, 3% polycarboxylate, 2% alkyl naphthalene sulfonate, light calcium carbonate and add to 100 % Parts by weight. The above-mentioned raw materials are prepared by conventional methods for preparing water-dispersible granules, namely, pre-mixing, jet pulverization, post-mixing, water-adding kneading, granulation, and sieving to obtain the 65% flufensulfuron methyl disulfuron-methyl water-dispersible granules .

Abstract

The invention relates to a mixed herbicide composition including mesosulfuron-methyl and flupyrsulfuron-methyl sodium. The herbicide composition employs mesosulfuron-methyl and flupyrsulfuron-methyl sodium as active ingredients, wherein the weight ratio of the active ingredients (flupyrsulfuron-methyl sodium : mesosulfuron-methyl) is 1:15-10:1. 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 pesticides and herbicides, and particularly relates to a herbicide for controlling weeds in wheat fields. It is composed of compound (A) flufluazasulfuron and compound (B) metsulfuron as active ingredients Binary herbicide composition. 【Background technique】 [0002] Wheat is one of the most important food crops in the world. The annual wheat output in my country accounts for about 22% of the total grain output. In addition to diseases and insect pests, weeds are also an important aspect of factors that harm wheat production and affect wheat yield. Weeds are non-target cultivated plants in farmland. Their main hazards are competition with crops for water, fertilizer, light and space, and they are also intermediate hosts of crop diseases and insect pests. The wheat field in my country accounts for about 30% of the wheat planting area, of which the seriously damaged area accounts for 8%, and the loss accounts for abou...
