Sulfonylurea herbicide is a selective internal absorption and conduction herbicide, 
which is absorbed mainly through root system, and rapidly transferred in the weed plant, 
inhibiting growth and gradually dying of weeds. Rice can decompose the drug, and it has little effect on rice growth. 
The efficacy is stable, the safety is high, and the duration of the efficacy is 25-35 days.
Applicable crops: rice seedling field, direct seeding field, transplanting field.
Control object: it can control annual and perennial broad-leaved weeds and Cyperaceae weeds, 
such as heterosexual Cyperaceae, water Cyperaceae, firefly rush, duck tongue grass, water celery, 
sarcandra, Sagittaria, Potamogeton, Azolla, chanchus. It has no effect on Echinochloa crusgalli and semen euphorbiae.
Usage: generally used in the 1~3 leaf stage of rice, 10% WP 15~30 grams per mu, and spray with water. 
Keep water layer for 3-5 days after treatment. Transplanting field, 3-20 days after transplanting medicine, after 5-7 days of water retention.
Attention: it is safe to rice, but late rice varieties (japonica and glutinous rice) are relatively sensitive, 
\so it should be avoided to apply it at late rice bud stage as far as possible, otherwise it is easy to cause pesticide damage.
