Product feature
Non-selective. Paraquat quickly kills the green parts of plants, including monocots and dicots, but is ineffective against the underground roots and stems of perennial weeds.
Fast weed killing. Within 2-3 hours after application, the leaves of the plant begin to change color and turn yellow, and the entire plant dies within 3-4 days.
Rapid soil decomposition. Paraquat decomposes quickly once it settles into the soil, allowing crops to be replanted soon after application.
Product introduction
Paraquat is a fast-acting non-selective herbicide with contact and systemic actions. It can be quickly absorbed by the green tissues of plants, causing them to wither and die. It has no effect on non-green tissues.
Mode of action
Photosystem I electron transport inhibitors. Destroy the chloroplast membrane, stop photosynthesis and chlorophyll synthesis, and promote dryness.
