Problems solved by technology

[0005] In actual use, trimethylbenzophenone mainly controls grass weeds, and is basically ineffective against broad-leaved weeds; rimsulfuron mainly controls broad-leaved weeds, but has no significant control effect on most grass weeds in the field

Embodiment 1

[0035] The preparation method of 5% trimethylbenzotrione · rimsulfuron-methyl emulsifiable concentrate: by weight percentage.

[0036]

[0037] Preparation method: Add the medicine into the container according to the proportion, add xylene, cyclohexanone and part of ethanol and stir evenly, add emulsifier according to the proportion, add the remaining amount of ethanol, mix evenly, and prepare 5% trimethylbenzotrione acyl pyrimide When sulfuron-methyl EC is applied at a dose of 200g / mu, it is used to control weeds in wheat fields, and the control effect on grass weeds such as scallops, apricots, and broad-leaved weeds, such as chrysalis and curly ears, can reach about 85%.

Embodiment 2

[0039] The preparation method of 75% trimethylbenzotrione · rimsulfuron-methyl wettable powder: by weight percentage.

[0040]

[0041] Preparation method: Add the components of the agent into the mixer according to the formula ratio and mix them evenly, then carry out airflow crushing, and stir well after the crushing is completed, and then the wettable powder product can be obtained. When the application dose is 20g / mu, it is used to control weeds in wheat fields , the control effect is better on the grass weeds Smilax, Acanthus and broad-leaved weeds, and the control effect is about 95%.

Embodiment 3

[0043] The preparation method of 20% trimethylbenzotrione · rimsulfuron-methyl oil suspension concentrate: by weight percentage.

[0044]

[0045]

[0046] Preparation method: according to the formula, weigh the above components in proportion, put them into a ball mill for ball milling for 30 minutes, and then grind them fully with a sand mill to control the particle diameter of the solid component within 2 microns, and stir evenly after grinding to obtain the oil suspension The product, when applied at a dosage of 50g / mu, is used to control weeds in wheat fields, and the control effect on gramineous weeds such as syringa, syringa, and broad-leaved weeds, such as chrysanthemum, and curly ear, is about 87%.

Abstract

The invention discloses a weeding composition containing tralkoxydim and amidosulfuron. The weeding composition comprises active components tralkoxydim and amidosulfuron at a weight ratio of 15-45:4-8. The weeding mechanisms of tralkoxydim and amidosulfuron are different, so that the advantages of the two components are maintained after combination, and better weeding effect is achieved; comparedwith using of single component, using of the weeding composition possesses following advantages: synergistic effect is achieved, using amount is reduced, cost is reduced, safety is improved, weeding spectrum is widened, excellent prevention effects on broadleaf weed and gramineous weeds are achieved. No interaction resistance between tralkoxydim and commercially available acetyl-CoA carboxylase herbicides (such as fenoxaprop-p-ethyl) is induced, so that the weeding composition can be used for killing gramineous weeds, such as Beckmannia syzigachne and Alopecurus japonicus, with drug resistanceon acetyl-CoA carboxylase herbicides, and generation of drug resistance caused by using of single component is delayed.

Description

technical field [0001] The invention relates to a herbicide used for controlling weeds in wheat fields, in particular to a herbicide composition containing trimethazone and rimsulfuron-methyl, which belongs to the technical field of pesticides. Background technique [0002] In the global pesticide market, herbicides account for 43% of the market and are increasing year by year. Wheat is the main crop in my country, and the number of herbicide varieties registered in the country is also in the forefront. However, due to years of use, some herbicides such as acetyl-CoA carboxylase inhibitors have produced varying degrees of drug resistance in wheat field weeds. Use in rotation. And the herbicide spectrum of different herbicides is different, and the appropriate herbicide should be selected according to the weed species. [0003] Trimethylbenzotrione is an oxime herbicide, which can effectively control wheat and barley field oystergrass, Japanese alopecia, alopecia, hard gra...
