Problems solved by technology

[0004] And usually corn field herbicides all have strong selectivity, and the herbicidal effect to a certain family weed is good but to another family weeds the effect is very poor, therefore can only repeatedly, multi-variety, multi-dose medication, exceed The amount and abuse of pesticides have brought negative impacts such as rice quality decline and environmental pollution, and increased the cost of pesticides.

Embodiment 1

[0015] A corn field herbicide composition, which is prepared according to the following parts by weight of raw materials: 20 parts by weight of trimethoprim, 15 parts of 2,4-D triisopropanolamine, 15 parts of chlorfentrazone, 23 parts of dichloropropene, 5 parts of glyphosate isopropylamine, 5 parts of nicosulfuron, 8 parts of flusulfuron. (1Kg per serving)

Embodiment 2

[0017] 30 parts of trimethoprim, 30 parts of 2,4-D triisopropanolamine, 20 parts of chlorfentrazone, 25 parts of allyl dichloride, 6 parts of glyphosate isopropylamine, 6 parts of nicosulfuron, fluorine 10 parts of sulfuron-methyl. (1Kg per serving)

Embodiment 3

[0019] 28 parts of fenoxazone, 21 parts of 2,4-D triisopropanolamine, 15 parts of chlorfentrazone, 24 parts of dichloro allylamine, 5 parts of glyphosate isopropylamine, 5 parts of nicosulfuron, fluorine 8 parts of sulfuron-methyl. (1Kg per serving)

[0020] When applying, in the early stage after sowing and before the seedlings, the plots when there are no weeds in the field can be treated with sealing; after the wheat is harvested, the fields with more annual weeds in the field should be mixed with technology, and the treatment method of "one shot and one kill" is implemented. .

Abstract

The invention discloses a cornfield herbicide composition, which is prepared from the following raw materials in parts by weight: 20-30 parts of bentazone, 10-30 parts of 2,4-D triisopropanolamine, 15-20 parts of cloransulam-methyl, 22-25 parts of dichlormid, 5-6 parts of glyphosate isopropylamine, 5-6 parts of nicosulfuron and 8-10 parts of prosulfuron. The cornfield herbicide composition provided by the invention has the advantages of high speed of pesticide effect taking, long pesticide application lasting period and time and labor saving. A synergy effect is presented as a weed control spectrum, higher speed of taking an effect of weeding and a longer prevention and treatment effect, harmful crops can be better controlled through application for one time or a few times, and a possible pesticide application interval is widened.

Description

Technical field [0001] The invention relates to a herbicide composition, in particular to a corn field herbicide composition. Background technique [0002] Maize is one of the most widely distributed food crops in the world, and its planting area ranks third after wheat and rice. Planting ranges from 58°N (Canada and Russia) to 40°South (South America). Corn matures every month in the world. [0003] The main weeds in the corn field are: crabgrass, amaranthus retroflexus, golden setter grass, stigmata, Eragrostis, nightshade, barnyardgrass, chinensis, quinoa, gray-green quinoa, purslane, amaranthus, pig hair Vegetables, Kochia scoparia, Amaranthus, Setaria, Amaranthus, Amaranth, Chenopodium, Green amaranth, Gooseweed, Green arachnid, Quinoa, Amaranthus, Abutilon, Wild watermelon seedlings, Amaranthus axillary and other weeds. Perennial weeds include bindweed, reed, and rot and so on. [0004] Generally, herbicides in corn fields are highly selective. They have good weed control e...
