Rice fields treated with Penoxsulam herbicide show good safety
Penoxsulam is a sulfonylurea herbicide. The drug is absorbed through weed leaves, stems and roots, and is translocated via the xylem and phloem to the meristematic zones where it acts. When used in rice fields, Penoxsulam provides both foliar treatment and soil residual (pre-emergence) control effects. After Penoxsulam treatment, weeds quickly stop growing; 2-4 days after application the growing points fade, and sometimes the leaf veins turn red; 7-14 days after application the stem tips and leaf buds begin to wither and necrose; 2-4 weeks after application the weeds die. The speed of weed death is related to the accumulation of branched-chain amino acids in the plant. Young
