Tribenuron-methyl is a chemical substance with a molecular formula of C15H17N5O6S  . For weeding. The mechanism is a selective systemic conduction type herbicide, which can be absorbed by the roots and leaves of weeds and conducted in plants. By inhibiting the activity of acetolactate synthase (ALS), it affects the biosynthesis of branched-chain amino acids (such as leucine, isoleucine, valine, etc.).

Common dosage forms

10% Tribenuron-methyl WP, 75% Tribenuron-methyl water dispersible granules (also known as dry suspension or dry suspension).

Prevention object

It is mainly used for the control of various annual broad-leaved weeds. It has better effects on Artemisia annua, Shepherd’s Purse, Broken Rice Shepherd’s Purse, Maijiagong, Quinoa, Amaranthus, etc. It also has a certain control effect. It has no significant effect on field thistle, polygonum cuspidatum, field bindweed, and lacquer, and is ineffective against grass weeds such as wild oat, kangaroo, brome, and jiejie.

Mechanism of action

This product is a selective systemic and conductive herbicide, which can be absorbed by the roots and leaves of weeds and conducted in plants. By inhibiting the activity of acetolactate synthase (ALS), it affects the biosynthesis of branched-chain amino acids (such as leucine, isoleucine, valine, etc.). After the plant is injured, the growth point is necrotic, the leaf veins are chlorotic, the plant growth is severely inhibited, dwarfed, and eventually the whole plant withers. Sensitive weeds stop growing immediately after absorbing the agent and die after 1-3 weeks.

Instructions

From the 2-leaf stage to the jointing stage of wheat, the weeds are applied before or early after the seedling. The general dosage of 10% Trisulfuron WP is 10-20g/mu, and the amount of water is 15-30kg, and the weed stems and leaves are evenly sprayed. When the weeds are small, a low dose can achieve better control effect, and when the weeds are large, apply a high dose

Precautions

1. This product can only be used once per season.

2 . This product has high activity, and the dosage should be strictly controlled during administration, and attention should be paid to mixing it with water evenly.

3. This product can only be used to control weeds that have emerged, and has poor control effect on weeds that have not been unearthed.

4. In windy weather, spraying and application should be stopped to prevent the drift of the liquid from causing phytotoxicity to adjacent broad-leaved crops.

5. The residual period of this product in soil is about 60 days.

6. Peanuts and potatoes (avoid chlorine) are sensitive to this product. In winter wheat fields where this product has been applied, peanuts should not be planted in the following stubble.
