Bensulfuron-methyl is a selective systemic conduction paddy herbicide with low toxicity to humans and animals, and low toxicity to fish, birds and bees. It was used to control sedge and broad-leaved weeds in rice fields earlier, and has been used to control broad-leaved weeds in wheat fields. The agent can diffuse rapidly in water, be absorbed and transferred to various parts of weed roots and leaves, and hinder the biosynthesis of branched-chain amino acids. It is used to control annual and perennial broad-leaved weeds and Cyperaceae weeds in paddy fields, and the effect on Gramineae weeds is poor. It is safe for wheat, rice and other crops.

Bensulfuron-methyl mechanism of action

Bensulfuron-methyl is a broad-spectrum selective systemic herbicide for sulfonylurea paddy fields. Bensulfuron-methyl is absorbed through the root system and quickly transfers in the weed plant, hindering the growth of valylic acid, leucine, and isosulfuric acid. The biosynthesis of leucine prevents the division and growth of cells, the growth function of sensitive weeds is hindered, the premature yellowing of young tissues inhibits the growth of leaves, and the growth of roots is hindered and necrotic.

Applications of  Bensulfuron-methyl

Bensulfuron-methyl is a broad-spectrum rice field herbicide, used for pre-emergence and early post-dental treatment, can effectively control many annual and perennial broad-leaved weeds and sedges, and quickly releases active ingredients after being applied to paddy fields. Absorbed by plants, quickly inhibits the growth of sensitive weeds.

It is a selective, systemic conduction type urea herbicide. Inhibitor of branched-chain amino acid synthesis. The active ingredient diffuses rapidly in the water, is absorbed by the roots and leaves of the weed, and is transferred to the various parts of the weed, hindering the biosynthesis of branched-chain amino acids, preventing cell division and growth, and hindering the growth of weeds and causing necrosis. It is suitable for controlling annual or perennial broad-leaved weeds in paddy fields. Apply pesticides after crops, weeds, and weeds. The recommended dosage is 0.2-0.45g/100m2 for toxic soil treatment or spraying. Such as rice direct seeding field or transplanting field, apply medicine within 3 weeks before and after sowing or transplanting, preferably 5-7 days after sowing or transplanting, use 10% wettable powder 2-3g/100m2, mix fine soil 3kg , field water layer 3 ~ 5cm, spread evenly. Bensulfuron-methyl was poor in control of grass weeds.

Used to control annual and perennial broad-leaved weeds and sedges in rice seedling fields, direct seeding fields and transplanting fields.

1. Rice seedling fields and direct seeding fields: the pesticide can be applied after sowing to the 2-leaf stage of weeds. To control 1-year-old broad-leaved weeds and sand grass, use 20-30 grams of 10% wettable powder per mu, spray 30 kilograms of water or mix 20 kilograms of fine fluvo-aquic soil. When spraying, keep the water layer 3-5cm for 3-4 days.

2. Transplanting rice into Chemicalbook field: It can be used within 3 weeks before and after transplanting, but it is better to apply the medicine 5-7 days after transplanting. Use 20-30 grams of 10% wettable powder per mu to control perennial weeds and barnyard grass, and the dosage can be increased to 30-50 grams. Water-retaining layer 5cm spraying, can be sprayed on water, can also be mixed with fine soil and sprinkled, keep the water layer for 3-4 days, and dry naturally.

Compound use of bensulfuron-methyl

1. The compound of bensulfuron-methyl and pretilachlor is used for sealing treatment after germination and sowing in direct seeding fields.

2. Combination of pyrazosulfuron-methyl and bispyribac, used to prevent and control various weeds in paddy fields except Pachyrhiza chinensis after 4 leaves;

3. Combination of pyrazosulfuron-methyl, cyhalofop-ethyl and bispyribac, used to control various weeds in paddy fields after 4 leaves of rice.

Precautions for Bensulfuron-methyl

1 Bensulfuron-methyl has a good effect on weeds within the 2-leaf stage, and the effect is poor if it exceeds 3 leaves

2 The effect on barnyardgrass is poor, and it is not suitable for use in seedling fields dominated by barnyardgrass

3 Rinse the spray equipment after use

4 When spraying, there must be a water layer of 3-5cm in the paddy field, so that the pesticide can be evenly distributed. 7 days after spraying, do not drain or string water, so as not to reduce the efficacy of the medicine

5 The dosage of this medicine is small and must be weighed accurately

6 Depending on the grass conditions in the field, it is suitable for plots dominated by broad-leaved weeds and grasses and plots with little barnyardgrass

7 This product cannot be mixed with food and feed
