★ Mechanism of action
This product is a selective internally absorbed and conductive herbicide that can be absorbed by the roots and leaves of weeds and transmitted within the plant body.By inhibiting the activity of acetyllactate synthase (ALS), it affects the biosynthesis of branched chain amino acids (such as leucine, isoleucine, valine, etc.).After being harmed, plants exhibit necrosis of growth points, loss of green leaf veins, severe inhibition of plant growth, and ultimately the entire plant withers. Sensitive weeds stop growing immediately after absorbing pesticides and die 1-3 weeks later.
★ Object of prevention and control
Mainly used to control various annual broad-leaved weeds, it has a good effect on flixweed, Shepherd's purse, Lithospermum arvense, Chenopodium album, amaranthus retroflexus, etc. It also has a certain control effect on summer cypress, chickweed and bedstraw.
★ Usage
From the 2-leaf stage to the jointing stage of wheat, apply pesticides early before or after weed seedlings. The general dosage is 75% benzsulfuron methyl water dispersible granules, 2-4g/mu, mixed with 15-30 kilograms of water, evenly sprayed with leaves. When weeds are small, low doses can achieve good control effects, while when weeds are large, high doses should be used.
★ Precautions
1. This product can only be used once per season for crops.
2. This product has high activity, and the dosage should be strictly controlled during application, and attention should be paid to mixing it evenly with water.
3. This product can only be used to control weeds that have already emerged, and its effectiveness in controlling weeds that have not yet emerged is very poor.
4. In windy weather, spray application should be stopped to prevent the drift of the medicinal liquid from causing drug damage to adjacent broad-leaved crops.
5. Peanuts are sensitive to this product. In winter wheat fields where this product has been applied, peanuts should not be planted in the following crops.
