Problems solved by technology

[0002] Grass generally exists in crop growing fields, and its existence will cause serious harm to crops from the seedling stage to the seedling stage and even the harvest stage; taking corn as an example, corn is in the two periods of pre-emergence and early post-emergence after sowing. It is a critical period for corn. During this period, unfavorable weed control will seriously affect the growth of corn seedlings and even affect the harvest of corn seedlings.
[0003] Among the weeds, Gramineae weeds are the most common. This kind of weeds has the characteristics of fast anyway, strong vitality and strong adaptability to drugs. In order to prevent them from harming crops, people have been using chemical herbicides to weed. The long-term use of herbicides has enhanced the resistance of this type of grass weeds, which has affected the performance of the drugs.
[0004] Topramezone is a broad-spectrum herbicidal compound, Mesotrione is an effective compound against dicotyledonous plants and grass weeds, and Bromoxynil octanoate is effective against Gramineae weeds have the compound of good control effect, although they all have higher killing effect to grasses weeds, but, single-agent use has the shortcoming of killing effect poor, and as very easy to produce resistance; Therefore , it is of great significance to provide a herbicide with high weed killing efficiency and reduced weed resistance

Embodiment 1

[0022] Formulation example 1: 70% fenflumezone·mesotrione·octanoyl bromoxynil suspension concentrate

[0023] Weigh 0.5% fenflumezone, 9.5% mesotrione, 60% bromoxynil, 3% TERSPERSE4894 (product of Huntsman, USA), 2% TERSPERSE2500 (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-mentioned 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·octanoyl bromoxynil.

Embodiment 2

[0024] Formulation example 2: 60% fenflumezone·mesotrione·octanoyl bromoxynil suspension concentrate

[0025] Weigh 3% fentrazone, 40% mesotrione, 17% bromoxynil, 2% TERSPERSE2020 (product of Huntsman, USA), 2% Span-60#, 2% Tween-60 #, 1% TERSPERSE2500 (product of Huntsman, USA), 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 sand-milled with a sand mill to prepare a suspension concentrate with an active ingredient content of 60% oxentrazone·mesotrione·octanoyl bromoxynil.

Embodiment 3

[0026] Formulation example 3: 55% fenflumezone·mesotrione·octanoyl bromoxynil suspension concentrate

[0027] Weigh 3% fentrazone, 12% mesotrione, 40% bromoxynil, 3.5% Nongru 2201, 1.5% TERSPERSE2500 (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 Deionized water. The above-mentioned 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·octanoyl bromoxynil.

Abstract

The invention provides a corn field herbicide composition containing topramezone, a composition preparation and an application thereof. Active ingredients of the composition comprise topramezone, mesotrione and bromoxynil octanoate in a weight ratio of (0.5-40): (1-40): (5-80), the composition is prepared into a preparation to be applied to removal of weeds in corn fields. In the composition, thetopramezone, the mesotrione and the bromoxynil octanoate are compounded, so that the weed control spectrum and the service life of the composition are expanded, and the composition particularly has atypical killing effect on gramineous weeds and is remarkable in killing effect.

Description

technical field [0001] The invention relates to the technical field of compound herbicides, in particular to a cornfield herbicide composition containing fenflumezone, a composition preparation and an application thereof. Background technique [0002] Grass generally exists in crop growing fields, and its existence will cause serious harm to crops from the seedling stage to the seedling stage and even the harvest stage; taking corn as an example, corn is in the two periods of pre-emergence and early post-emergence after sowing. It is a critical period for corn. During this period of time, unfavorable weed control will seriously affect the growth of corn seedlings and even affect the harvest of corn seedlings. [0003] Among the weeds, Gramineae weeds are the most common. This kind of weeds has the characteristics of fast anyway, strong vitality and strong adaptability to drugs. In order to prevent them from harming crops, people have been using chemical herbicides to weed. ...
