    Pyrazosulfuron-ethyl belongs to the sulfonylurea herbicide, which is a selective endosuction conduction herbicide. It is mainly absorbed through the root system and rapidly transfers in the body of the weed plant, which inhibits the growth and gradually kills the weed. Rice can decompose the chemical and has little effect on rice growth. The efficacy is stable, the safety is high, the duration is 25~35 days.

    Applicable crops: rice seedling field, direct field, transplanting field.

    Control object: can control annual and perennial broad-leaved weeds and sedge weeds, such as water sedge, var. irin, hyacinth, water cress, acanthophylla, wild cinea, eye sedge, green duckweed, channa. It has no effect on tares grass.

    Usage: Generally used in rice 1~3 leaf stage, with 10% wettable powder 15~30 grams per mu mixed with toxic soil, can also be mixed with water spray. Keep the water layer in place for 3 to 5 days. In the transplanting field, the drug was applied for 3 to 20 days after insertion, and the water was kept for 5 to 7 days after insertion.

    Note: It is safe for rice, but it is sensitive to late rice varieties (japonica and waxy rice). It should be avoided to apply it at the late rice bud stage, otherwise it is easy to produce drug damage.
