Embodiment 1

[0028] Weigh 0.5% fentrazone, 9.5% mesotrione, 60% atrazine, 3% TERSPERSE 4894 (product of Huntsman, USA), 2% TERSPERSE 2500 (product of Huntsman, USA), 2% Diffusion agent NNO, 2% magnesium aluminum silicate, 0.2% xanthan gum, 5% ethylene glycol, 0.5% formaldehyde, 0.5% silicone defoamer (trade name: s-29 product of Nanjing Sixin Applied Chemicals Co., Ltd.) , The balance is deionized water. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sand-milled with a sand mill to prepare a suspension concentrate with an active ingredient content of 70% oxentrazone·mesotrione·atrazine.

Embodiment 2

[0030] Weigh 3% fentrazone, 40% mesotrione, 17% atrazine, 2% TERSPERSE 2020 (product of Huntsman, USA), 2% Span-60#, 2% Tween-60# , 1% TERSPERSE 2500 (U.S. Huntsman product), 2% bentonite, 0.3% xanthan gum, 3% propylene glycol, 0.5% benzoic acid, 0.5% silicone defoamer (trade name: s-29 Nanjing Sixin Applied Chemicals Company), 1% epichlorohydrin, and the balance is deionized water. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare a suspension concentrate with an active ingredient content of 60% oxentrazone·mesotrione·atrazine.

Embodiment 3

[0032] Weigh 3% fentrazone, 12% mesotrione, 40% atrazine, 3.5% Nongru 2201, 1.5% TERSPERSE 2500 (product of Huntsman, USA), 2% sodium lignosulfonate, 2% % polyvinyl alcohol, 0.2% xanthan gum, 5% ethylene glycol, 0.5% benzoic acid, 0.5% organosilicon defoamer (trade name: s-29 product of Nanjing Sixin Applied Chemicals Co., Ltd.), and the balance is to ionized water. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sand-milled with a sand mill to prepare a suspension concentrate with an active ingredient content of 55% oxentrazone·mesotrione·atrazine.

Abstract

The invention discloses a topramezone-containing herbicide composition for a corn field. The composition consists of topramezone, mesotrione and atrazine; the weight ratio of topramezone to mesotrione to atrazine is (0.5-40): (1-40): (5-80); the sum of the contents of topramezone, mesotrione and atrazine is 5-85 percent of the total weight of the composition. The composition can be prepared into a suspending agent, water dispersing granules, wettable powder or a dispersible oil suspending agent which is available in agriculture. The components of the composition are reasonable in mixing and an outstanding synergism effect is achieved; the prevention and treatment effect on weeds in the corn field is enhanced, the prevention and treatment spectrum for the weeds in the corn field is expanded, the pesticide application period is prolonged, and the pesticide use cost is lowered; the prepared dose form is high in safety to corns; the composition has a relatively good prevention and treatment effect on grassy weeds and broadleaf weeds in the corn field.

Description

technical field [0001] The invention belongs to the technical field of compound pesticides, and relates to a herbicide composition, in particular to a cornfield herbicide composition containing fenflumezone. The herbicide composition contains not only the active ingredient fenflumezone, but also the effective ingredients mesotrione and atrazine, and is suitable for controlling weeds in cornfields. Background technique [0002] Weeds in cornfields are common and there are many kinds, mainly broad-leaved weeds such as retroflexus, quinoa, bindweed, black nightshade, amaranth, velvet hemp, amaranth, purslane, cocklebur, commelina, Beef chickweed, etc.; grass weeds such as barnyardgrass, crabgrass, foxtail, goosegrass, bermudagrass, stephenia, etc.; sedge weeds such as Cyperus cyperus. Weeds compete with corn for water, nutrients, light and space, affecting the normal growth of corn seedlings and even causing severe yield reduction. Corn seedlings are most seriously harmed by ...
