ATLAS INDIGO - Application
Open Data Verified Data
plant growth regulators, herbicides. Not only can inhibit p-amylase activity, inhibit plant RNA, protein synthesis, interference with oxidative phosphorylation and photosynthesis, damage cell division. Or a highly selective pre-or early post-seedling herbicide, the agent is absorbed by the grass weed Bud sheath, mainly absorbed by the root of the plant, but also absorbed by the leaves, in the body up, downward two-way conduction, can effectively control wheat, corn, alfalfa, sunflower, amaranth, beet, rice, bean, carrot, spinach, lettuce, onion, pepper and other crops to control annual grass weeds and part of the broad-leaved grass. Single use or mixed use, can control sensitive weeds. According to the different soil organic matter and temperature, Appropriately increasing the dosage can expand the spectrum of killing grass.

| use | is both a plant growth regulator and a herbicide. It can inhibit the activity of β-amylase, inhibit the synthesis of plant RNA and protein, interfere with oxidative phosphorylation and photosynthesis, and destroy cell division, so it can significantly inhibit the germination power of potato during storage. It can also be used for thinning flowers and thinning fruits of fruit trees. At the same time, chloraniline is a highly selective herbicide before or early after seedling. The agent is absorbed by the grass weed bud sheath, mainly absorbed by the roots of plants, and can also be absorbed by the leaves, upward and downward in the body Two-way conduction, it can effectively control annual gramineous weeds and some broadleaf grasses in wheat, corn, alfalfa, sunflower, potato, sugar beet, soybean, rice, kidney bean, carrot, spinach, lettuce, onion, pepper and other crops. It is used for bud suppression of potato. It is used after harvest to be damaged and naturally healed (about 14 days or more) and before sprouting. The medicine is mixed with dry soil and evenly sprinkled on the potato. The dosage is 1.4~2.1kg of 0.7% powder (active ingredient 9.8~14.7g) per ton of potato. Or 400~600g of 2.5% powder (10~15g of active ingredient). The weeds used for control mainly include raw grass seedlings, barnyard grass, wild oats, bluegrass, shepherd's purse, amaranth, oat grass, ryegrass, chickweed, corn grass, polyphylla, purslane, field dodder, etc. Soil treatment is carried out after sowing and before seedlings, and 0.7% powder 157~425kg/hm2 is used alone or in combination to control sensitive weeds. According to the different soil organic matter and temperature, the grass killing spectrum can be expanded by appropriately increasing the dosage. used to inhibit potato germination during storage mitotic poison; inhibit plant metabolism. In agriculture, it is used as a selective pre-bud herbicide to control weeds in crops such as carrots, leeks, and onions. |
