Herbicides

Sulfonylsulfuron is an organic substance that can be used as a herbicide.

Trifluralin is a pre bud herbicide, which is used to control annual weeds in cotton and forage bean fields. It is used as herbicide for fruit, cotton, soybean and other crops. It is an excellent dry field herbicide. It is mainly used for cotton, soybean, peanut, sunflower, cabbage, pepper, beans, orchards, etc. it can also be used in wheat fields and dry rice fields to control many annual grasses and seed propagation weeds and some broad-leaved weeds, such as barnyardgrass, Dogtail, horse Tang, granny, cricket grass, thousand gold, bluegrass, bromegrass, wild oats, sparrow tongue, quinoa, amaranth, corn grass, Zoysia Rehmannia, purslane, etc.

Novel oxime esters, broad-spectrum selective post sprout herbicides. The mechanism of action is similar to sulfonylurea and imidazolidinone herbicides, both of which belong to acetyllactate synthase (ALS) inhibitors. It has selective ultra-high effect on rice, common wheat and Zoysia japonica. It has no pre bud herbicidal activity. It is used to control all kinds of gramineous weeds and broad-leaved miscellaneous rowing, such as barnyardgrass, Eupatorium grandiflorum, Polygonum hydropiper, and is safe for rice and common wheat. The speed of herbicide weeding is slow, and it can inhibit the growth of weeds after application, but it must die after 2 weeks. The medicament is moderately wide and effective for barnyardgrass at 1.5 ~ 6.5 leaf stages. At 2.5 ~ 3.5 leaf stage, the dose of 10g/hm2 can reach 100% control; When the dosage is increased to 20g/hm2 at 3.5 ~ 4.5 leaf stage, 100% control can be achieved.

Oryzalin is a pre bud herbicide, which can be used alone or mixed with other herbicides to control weeds in cotton, peanut, winter rape, soybean and sunflower fields.
