Embodiment 1

[0021] Get 185 grams of the original drug of acetochlor and add 200 grams of white carbon black, 65 grams of sodium alkylbenzene sulfonate, 535 grams of kaolin, and 15 grams of chlorimuron-methyl. After stirring evenly, use a jet mill to pulverize the medicament to 325 meshes to make a wettable powder with an effective content of 20%.

Embodiment 2

[0023] Get 190 grams of the original drug of acetochlor and add 210 grams of white carbon black, 60 grams of sodium alkylbenzene sulfonate, 530 grams of kaolin, and 10 grams of chlorimuron-methyl. After stirring evenly, use a jet mill to pulverize the medicament to 325 meshes to make a wettable powder with an effective content of 20%.

Embodiment 3

[0025] Get 180 grams of the original drug of acetochlor and add 200 grams of white carbon black, 70 grams of sodium alkylbenzene sulfonate, 530 grams of kaolin, and 20 grams of chlorimuron-methyl. After stirring evenly, use a jet mill to pulverize the medicament to 325 meshes to make a wettable powder with an effective content of 20%.

[0026] The following is the safety of acetochlor and chlorimuron-methyl on sugarcane and the control effect on weeds at 20% active ingredients.

Abstract

The invention relates to a highly effective, wide spectrum, economic and safety sugar cane land herbicide prepared from acetochlor and chlorimuronethyl by the weight percentage of acetochlor 95-70% and chlorimuronethyl 5-30%, the herbicide exhibits high safety for sugar cane but fine effect for single or double cotyledon weeds.

Description

technical field [0001] The present invention relates to the field of chemical herbicide compositions for use in sugarcane fields. Background technique [0002] Chemical herbicides have dominated the global pesticide market since the 1980s. In developed countries, chemical herbicides are used in almost all crops, but there are relatively few varieties of chemical herbicides in sugarcane fields, and their activity is not high (the amount of commercial use is about 500-1000 grams / mu). The cost is also high (8-10 yuan per mu). Take the sugarcane field herbicides 20% Di, 2, and WP that are currently being used in production as an example. The commercial dosage per mu is 600 grams, and the use cost is 9 yuan. Contents of the invention [0003] The object of the present invention is to provide a high-activity, low-cost high-efficiency, safe and economical compound sugarcane chemical herbicide. [0004] The herbicide composition that the present invention adopts is: [0005] A...
