 Chlorpropham Application:

1. This product is both a plant growth regulator and a herbicide.
It is often used to inhibit potato germination due to its ability to inhibit β-amylase activity, inhibit the synthesis of plant RNA and protein, interfere with oxidative phosphorylation and photosynthesis, and destroy cell division. It can also be used for flower thinning and fruit thinning of fruit trees.
2. Chloraniline is a highly selective pre-emergence or early post-emergence herbicide. The drug is absorbed by the coleoptiles of the grass weeds, mainly by the roots of the plants, and can also be absorbed by the leaves, up and down in the body. Two-way conduction can effectively control annual grass weeds and some broadleaf grasses in crops such as wheat, corn, alfalfa, sunflower, bell amaranth, sugar beet, soybean, rice, kidney bean, carrot, spinach, lettuce, onion, pepper and so on.
3. It is used to suppress the budding of potatoes. After harvesting, the damage will heal naturally (about 14 days or more) and before germination. Mix the medicament with fine dry soil and evenly sprinkle the medicament with fine dry soil on the potatoes. The dosage is per ton of potatoes. Use 0.7% powder 1.4 ~2.1kg (active ingredient 9.8~14.7g);
Or use 2.5% powder 400~600g (active ingredient 10~15g).
The weeds used for control mainly include raw grass seedlings, barnyardgrass, wild oats, bluegrass, multiflora ryegrass, chickweed, corn grass, shepherd’s purse, amaranth, oat grass, field dodder, flat storage, purslane, etc. Soil treatment is carried out after the crops are sown and before the seedlings,
Use 0.7% powder 157 ~425kg/hm2 alone or in combination to control sensitive weeds
