Product name: Chlorsulfuron

CAS NO.: 64902-72-3

Molecular weight: 357.77

Molecular formula: C12H12ClN5O4S

Systemic, super-efficient sulfonylurea herbicide. After the agent is absorbed by the leaves or roots of the weeds, it can be transmitted to the whole body of the plant. By inhibiting the activity of acetolactase, it hinders the synthesis of branched chain amino acids, valine and leucine, thereby stopping cell division and chlorosis of the plant. Withered and died.

Used to control broad-leaved weeds and gramineous weeds in cereal crop fields, such as quinoa, polygonum, amaranth, porphyra, abutilon, field bindweed, field thistle, buckwheat vine, matricaria, as well as setaria, ryegrass , Poa, small root garlic and so on. It has poor effect on wild oats and nightshade. It is used before or early post-emergence. Generally, it is applied before the emergence of autumn crops or after the emergence of spring weeds. It is better to treat the leaves after emergence. Use 0.15～0.6g active ingredient/100m2 to spray on water. It has a good effect when mixed with chlorotoluron and isoproteron. Crops that are sensitive to subsequent crops include corn, rapeseed, etc., and the amount of pesticides over 0.6g has a slight impact on subsequent crops of rice.

How to use

Weeds can be used before or after buds, and the effect of spraying on leaves after buds is better. Generally, fall crops are applied before budding after sowing or after weeds in spring. Use 1-2 grams of active ingredients per mu to spray on water.

Precautions

Chlorsulfuron is highly effective and has a long residual effect period. The amount of use must be strictly controlled and cannot be increased at will to avoid adverse effects on subsequent crops.
