Description
The toxicity of Low toxicity for human. Rat acute oral LD50 is 1100-2300 mg/kg, in rats with acute percutaneous LD50 > 20000 mg/kg. Chronic toxicity test did not see abnormalities. Two years full feed dogs and rats no effect dose of 100 mg/kg. The fish and aquatic organisms, the birds and the bees are low toxicity.
The English common name metribuzin
The name of the other Metribuzin, cyc (Sencor) and Eric (Lexone), Beyer94337, a grass lamictal.
Chemical name: amino - 4-6 - (1, 1-2 methyl ethyl) - 3 - methyl sulfonium - 1, 4-trichlorobenzene triazine - 5 - four hydrogen.
The physical and chemical properties Single product is colorless crystalline, density 1. 28 g/cm3 (20 ℃), melting point 125.5 ℃ to 126.5 ℃. 20 ℃ solubility in water of 1.2 g/l. , 120 g/L toluene, methanol, 450 g/L.
Formulations were 50%, 70% wettable powder, 50% dry suspending agent.
Characteristics is the selective herbicide, absorbed by the root, stem, leaf also can be absorbed. For 1 year broadleaf weeds and part of gramineous weeds has good control effect, the perennial weeds is invalid. Efficacy of how much affected by soil type, organic matter content, humidity, temperature influence is bigger, the strict conditions of use, improper use, or invalid, or producing the adr.
Scope of application Apply soy, potato, tomato, alfalfa, asparagus, crops such as sugar cane field control smartweed, amaranth and quinoa, mustard, potentilla, chickweed, buckwheat vines, Chinese mosla herb, a. annua, ghost needle grass, green bristlegrass, duck plantar grass, xanthium sibiricum, morel, digitaria, wild oats born broadleaf and grass in part 1 in gramineous weeds.
Method of use
1. Soybean fields use Before spring soybean seeding, with 70% wettable powder per acre 53-76 grams, 30 kilograms of water, soil surface evenly spray cloth. Before the summer soybean after sowing, with 70% wettable powder 33 per acre - 57 grams, spring soybean processing.
2. Potato fields use Use before seeding emergence, per mu with 70% wettable powder 66-76 grams, 30 kilograms of water, soil surface evenly spray cloth, used after emergence, generally at the potato plant height more than 10 cm, resistance to drop, easy generation the adr.
Matters needing attention
1. Soybean fields can only be used before seedling, seedling stage using the adr.
2. Sandy soil organic matter content less than 2% under unfavorable use.
3. High temperature low organic matter content areas, the medication with a low limit, in contrast with the high limit.
4. On or after every other crops are Chinese cabbage, pea under such as have the adr, pay attention to use period.

Experimental Properties:Slight sulfurous odor /Technical metribuzin/
Air and Water Reactions:No rapid reaction with air. No rapid reaction with water.
Reactive Group:Amides and Imides
Reactivity Profile:A triazine derivative. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.
Flammable Limits:Noncombustible Solid
Corrosivity:Non-corrosive
