Embodiment 1

[0025] Weigh 55% dicamba, 20% methyl disulfuron, 2% sodium lauryl sulfate, 3% calcium lignosulfonate, 3% dispersant NNO (alkyl naphthalenesulfonate formaldehyde condensate), kaolin Add 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% dicamba-methylsulfuron-methyl wettable powder.

Embodiment 2

[0027] Weigh 58% dicamba, 2% methyl disulfuron, 2% sodium lauryl sulfate, 4% calcium lignosulfonate, 3% TERSPERSE2700, 2% sodium dibutylnaphthalenesulfonate, 3% white carbon Black and kaolin are added to 100% by weight. The above-mentioned raw materials are pre-mixed, air-jet milled and post-mixed through conventional methods for preparing wettable powders to obtain the 60% dicamba-methylsulfuron-methyl wettable powder.

Embodiment 3

[0029] Weigh 18% dicamba, 22% methyl disulfuron, 1% sodium lauryl sulfate, 3% polycarboxylate, 2% alkylnaphthalene sulfonate, light calcium carbonate to 100% by weight . The 40% dicamba-methylsulfuron-methyl water-dispersible granules were obtained by conventional methods for preparing water-dispersible granules from the above raw materials, ie, pre-mixing, jet milling, post-mixing, kneading with water, granulation, and sieving.

Abstract

The invention relates to a mixed herbicide composition including mesosulfuron-methyl and dicamba. The herbicide composition employs mesosulfuron-methyl and dicamba as active ingredients, wherein the weight ratio of the active ingredients (dicamba : mesosulfuron-methyl) is 1:0.7-60:1. 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 a binary herbicide composed of compound (A) dicamba and compound (B) methylsulfuron-methyl as active ingredients agent composition. 【Background technique】 [0002] Wheat is one of the most important grain crops in the world, and the annual output of wheat in my country accounts for about 22% of the total grain output. The factors that harm wheat production and affect wheat yield, besides diseases and insect pests, weeds are also an important aspect. Weeds are non-target cultivated plants in farmland. Their main hazards are to compete with crops for water, fertilizer, light and space, and they are also intermediate hosts of crop diseases and insect pests. The area of ​​weed damage in wheat fields in my country accounts for about 30% of the wheat planting area, of which 8% is severely damaged, and the...
