Common name: Paraquat（CAS NO: 4685-14-7）

IUPAC name:  1,1′-dimethyl-4,4′-bipyridinium

Chemical Abstracts name: 1,1′-dimethyl-4,4′-bipyridinium

CAS No:  4685-14-7

Mode of action: 
Fast-acting, broad-spectrum, contact-killing, and herbicides. The bipyridyl cation is rapidly absorbed by the leaves of the plant, and is reduced to the bipyridyl radical by photosynthesis and respiration in the green tissue, and the water and oxygen in the leaf tissue form hydrogen peroxide and peroxy radical by auto-oxidation. The chloroplast membrane is destroyed, and the photosynthesis and chlorophyll synthesis are suspended, which promotes dryness. The medicament is used before the seedling, loses its activity in contact with the soil, and has no effect on the crop seedlings unearthed after spraying. It has no effect on brown bark, and the woody plant trunk is safe. Light will increase the effectiveness of the drug. The cloudy day delays the drug.

Application:  

It can be used before the emergence of crops to kill ground weeds and dry them for weeding in orchards, mulberry gardens, rubber gardens, rice fields, dry land and no-tillage plantations.

After harvesting wheat and rapeseed, without ploughing, the front stalk and field weeds are directly treated with 20% water agent 30-45ml/100m2, and water 3~4.5kg is foliarized. This method can also be used after rice harvesting. Can also be used in orchards, mulberry gardens, rubber gardens, tea gardens, paddy fields, wheat field weeds (cattle felt, sedge, maiden, piglet, sorghum, foxtail, yarrow, bamboo grass, etc.), generally Spray with water of 3.75 kg with 20% water 30-45 ml/100 m2.
