    Use 1
    Used to inhibit potato germination during storage
    Use 2
    It's both a plant growth regulator and an herbicide. It can inhibit the activity of β-amylase, inhibit the synthesis of RNA and protein, interfere with oxidative phosphorylation and photosynthesis, and destroy cell division, so it can significantly inhibit the germination ability of potato when stored. It can also be used for thinning flowers and fruits of fruit trees. At the same time, chloraniline is a highly selective pre-emergence or early post-emergence herbicide, which is absorbed by the bud sheath of grass weeds, mainly by the root of the plant, but also by the leaves, and is conducted in the body in both upward and downward directions. Can effectively control wheat, corn, alfalfa, sunflower, potato, beet, soybean, rice, string bean, carrot, spinach, lettuce, onion, pepper and other crops in the field of annual grass weeds and some broad-leaved grass.
    It is used for potato bud inhibition. After harvest, wait for the damage to heal naturally (about 14d or more) and before budding, mix the agent with fine dry soil and evenly sprinkle on the potatoes. The dosage is 1.4-2.1kg (effective composition 9.8-14.7g) of 0.7% powder per ton of potatoes. Or use 2.5% powder 400 ~ 600g (active ingredient 10 ~ 15g).
    The main weeds used for control are raw grass seedlings, barnyard grass, wild oats, bluegrass, purse purse, amaranth, oat grass, multi-flower ryegrass, chickweed, lugo grass, Purslane, field dodder, etc. Sensitive weeds can be controlled by soil treatment before seeding with 0.7% powder 157-425kg /hm2 alone or mixed. According to the different soil organic matter and temperature, the herbicidal spectrum can be expanded by increasing the appropriate dosage.
    Use 3
    Selective pre-emergence herbicide to control weeds in carrots, leeks, Onions and other crops
