Herbicide Diquat dibromide monohydrate 40%TC Cas 6385-62-2 Details

Diquat dibromide monohydrate is a non-selective contact herbicide with slight conductivity. After being absorbed by green plants, it inhibits the electron transfer of photosynthesis. Under the induction of light, the bipyridine compound in the reduced state is quickly oxidized in the presence of oxygen to form active hydrogen peroxide. The accumulation of this substance destroys the plant cell membrane, and the affected The part of the medicine is withered and yellow. Since it cannot penetrate the mature bark, it has basically no destructive effect on the underground pole stem.

Diquat dibromide monohydrateweeding targets and characteristics

Diquat dibromide monohydrate can be used in orchards, fields, non-cultivated land, and crushed rice sedge in the ground before planting. It has excellent effects on a variety of broad-leaved weeds and a long-lasting effect. It has better quick-acting effects on gramineous weeds. Efficacy is poor and easy to turn green.

Diquat dibromide monohydrate can also be used as a new type of withering desiccant, which has been used in crop fields such as potato, rice, rapeseed and flax. Diquat dibromide monohydratetreatment can significantly reduce the water content of crop grains, and has no effect on seed vigor.

Like paraquat, it belongs to the bipyridine herbicide class. It is a contact-killing herbicide that can be quickly absorbed by green plant tissues, but it will lose its activity immediately after contacting soil. However, paraquat is extremely toxic to humans, and there is no specific antidote.

Diquat dibromide monohydrate is a moderately toxic herbicide. Diquat dibromide monohydrateis low toxic to bees, earthworms and fish, moderately toxic to silkworms, birds and daphnia, and highly toxic to algae.

Mechanism and mode of action of diquat

Diquat dibromide monohydrate absorbed by green plants can inhibit the electron transfer in photosynthesis. Under the light induction, the bipyridine compound in the reduced state is quickly oxidized in the presence of oxygen species to form hydrogen peroxide, and the accumulation of hydrogen peroxide It will damage the plant cell membrane, causing the affected part of the plant to turn yellow and then gradually wither.

Diquat dibromide monohydratetest performance

1. Using 120-200mL of 20% Diquat dibromide monohydrate water agent per mu has a good control effect on early-growing broad-leaved weeds in corn-protected cultivated land, and is relatively safe for corn. Pay attention to the concentration and operation method.

2. Using 200g/L Diquat dibromide monohydrate water agent with an active ingredient dosage of 800-1000 per hectare has excellent effect on weeds on non-cultivated land.

3. The dosage of 200g/L Diquat dibromide monohydrate dibromide soluble agent is 1200~1500g per hectare, which has a fast and efficient effect on potato withering. After treatment with diquat, the potato yield increased significantly. Diquat dibromide monohydratehas zero residue in potatoes after withering, so Diquat dibromide monohydratehas high safety. It is recommended to use it 7-10 days before the potato is harvested, and use it under the instructions or the guidance of a technician.

Applications of Diquat dibromide monohydrate

Non-selective contact herbicide, slightly conductive. After being absorbed by green plants, it inhibits the electron transfer of photosynthesis. Under the induction of light, the bipyridine compound in the reduced state is quickly oxidized in the presence of oxygen to form active hydrogen peroxide. The accumulation of this substance destroys the plant cell membrane, and the affected The part of the medicine is withered and yellow. It is suitable for weeding in plots dominated by broad-leaved weeds; it can also be used as a desiccant for seed plants; it can also be used as a withering agent for crops such as potatoes, cotton, soybeans, corn, sorghum, flax, and sunflower; when dealing with mature crops, the residual The green parts and weeds of the plant dry up quickly, which can be harvested earlier and with less seed loss; it can also be used as an inhibitor of sugarcane inflorescence formation. Since it cannot penetrate the mature bark, it has basically no destructive effect on the underground pole stem. For crop withering, the dosage is 3-6g active ingredient/100m2. For weeding in farmland, the amount of no-tillage weeding in summer corn is 4.5-6g active ingredient/100m2, and in orchard is 6-9 active ingredient/100m2. Do not spray directly on the saplings of the crops, because contact with the green parts of the crops will cause phytotoxicity.
