Usage:Systemic conduction broad-spectrum herbicide. It mainly inhibits the enol acetonyl shikimidin phosphate synthase in plants, thereby inhibiting the conversion of shikimate to phenylalanine, tyrosine and tryptophan, which interferes with protein synthesis and causes plant death. It was originally used in rubber plantations to control thatch and other weeds, which can make rubber trees tapped one year earlier and are produced by old rubber trees. It is now gradually spread to forestry, orchards, mulberry gardens, tea gardens, rice-wheat, rice and rapeseed rotation fields.
