CYANAZINE(Technical,50wp,40sc)
COMMON NAME:Cyanazine
CHEMICAL NAME:2-(4-chloro-6-ethylamino-1,3,5-triazin-2-ylamino)-2-metylpropinitrile.
STRUCTURAL FORMULA:
PHYSICAL AND CHEMICAL PROPERTIES:TC cyanazine(≥95% pure)is a colourless crystalline solid; m.p. 166.5-167.0oC; V.P.200nPa(20oC). Solubility(25oC) ;171mg/l water; 15g/l benzene; 210g/l chlorofrom; 45g/l ethanol; 15g/l hexane. Stable to heat (1.8% decomposition after 100h at 75oC), to litht, and to hydrolysis(5≤PH≤9).
TOXICOLOGY:Mammalian toxicity.Acute oral LD50 for rats the value is from 288mg ai/kg;for mice 380mg/kg.Acute percutaneous LD50for rats>1200mg/kg.In 2-y feeding trials NOEL:for rats 12mg/kg diet;for dogs 25mg/kg diet.Rapidly metabolised and eliminated from the body by rats and dogs within c.4d.

Fineness,%(m/m) 98(44um) 98(75um)
CHARACTERISTICS AND USES:It is a selective herbicide:It has the great function to kill the weeds of grass family and broad leafed rank grass in the corn field.It can be used before the corn seed hasnit sprouted or after emergence of seedling but 4 leaves.Used 50WP 3.00-3.25Kg/ha or 40sc 3.75-4.5kg/ha mixing with 40-50kg water water and spraying.Other crops for which it is used including:cotton, oilseed rape,forestry, potatoes, soybeans, suqarcane. Laboratory tests show that the nitrile group is hydrolysed in plants adn soil to the corresponding carboxylic acid. The chlorine atom may also be replaced by ahydroxy group,which sometimes forms conjugates.These degradation proudcts have not been detected in crops following field use.
PRECAUTION:
1.Do not use it after the corn grows 5 leaves.
2.For the control of broad-leaved weeds use 25 EC Bromoxynil octanoate 1200ml/ha mixing with 50 wp or 40sc cyanazine 2250g/ha, 3000g/ha respectively.
3.To spread the herbicide is harmful to the corn for a heary rain rapidly.
4.Stored in normal condition, the period of guarantee quality is two years.
