Problems solved by technology

Diflufenamide mainly controls broad-leaved weeds, except bluegrass and barnyardgrass, but has no significant control effect on most gramineous weeds; methylsulfuron mainly controls gramineous weeds , especially for the dominant weeds in the wheat field such as common oystergrass, kanji, japanese kanji, and wild oats, but has no significant control effect on most broad-leaved weeds in the field

Embodiment 1

[0031] The preparation method of 33% diflufenican · mesosulfuron wettable powder: by weight percentage.

[0032]

[0033] Preparation method: fully absorb the liquid components with white carbon black, kaolin and attapulgite, then add them into the mixer according to the formula ratio and mix them evenly, carry out air-jet milling, and fully stir them evenly after the milling is completed to obtain wettable powder products. The dosage of the preparation per mu is 8-20g to prevent and control the grass weeds of wheat fields such as syringa, syringa, and broad-leaved weeds such as geranium and curly ear, and the control effect of the fresh weight of the total grass can reach 91%.

Embodiment 2

[0035] The preparation method of 20% diflufenican·sulfuron-methyl oil suspension concentrate: by weight percentage.

[0036]

[0037]

[0038] 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 product. The amount of preparation per mu is 8-20g for the prevention and control of gramineous weeds of wheat fields such as syringa, safflower and broad-leaved weeds such as geranium and curly ear, and the control effect of the fresh weight of the total grass can reach 90%.

Embodiment 3

[0040] The preparation method of 25% diflufenican · mesosulfuron wettable powder: by mass percentage.

[0041]

[0042] Preparation method: with embodiment 1. The dosage of the preparation per mu is 8-20g to prevent and control the grass weeds of wheat fields such as syringa, syringa, and broad-leaved weeds such as geranium and curly ear, and the control effect of the fresh weight of the total grass can reach 91%.

Abstract

The invention discloses a weeding composition containing diflufenican and mesosulfuron. The weeding composition contains the active components, namely diflufenican and mesosulfuron, in a weight ratio of (20-1):1. The weeding composition disclosed by the invention has the characteristics that the advantages of two single dosages, namely diflufenican and mesosulfuron, are combined after compounding as the diflufenican and mesosulfuron are different in weeding mechanism, the better weeding effect is achieved, synergistic effect is realized compared with use of single dose, dosage is reduced, cost is reduced, and safety is higher; weed controlling spectrum is expanded, and control effect on broadleaf weeds and gramineous weeds is better; and meanwhile, insecticide resistance produced by use of the single dose can be alleviated.

Description

technical field [0001] The invention relates to a herbicide for controlling weeds in wheat fields, in particular to a herbicide composition containing diflufenamide and disulfuron-methyl, and 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] Diflufenamide is a selective herbicide. After being absorbed by weed shoots, it inhibits phytoene dehydrogenase (PDS), hinders the biosynthesis of caroten...
