The feeding test of rat 90d was 1000mg/kg without any dose and 500mg/kg for dogs. After 2 years of feeding test, the rats had no action dose of 1000mg/kg and mice were 3000mg/kg. Animal tests showed no teratogenic, carcinogenic and mutagenic effects. Toxic to fish, rainbow trout LC50 is 3.9mg/L, catfish LC50 is 4.9mg/L. Low toxicity to birds. It has gastric toxicity to bees but no contact toxicity.
The pure product is colorless liquid and the industrial product is brown oily liquid. B.p.100 C /0.133Pa, vapor pressure 1.73 * 10-3Pa (20 C), relative density 1.12 (20). Soluble in methanol, two chloroethane and other organic solvents, the solubility in water is 530mg/L. It is not easy to decompose by light, storage for two years is stable, and the half-life is 25d.
Use of selective herbicide. Gramineous weeds inhibit protein synthesis and death by absorbing buds and young roots. It is suitable for maize, soybean, rape, cotton, sorghum, vegetable and other crops. It can prevent and control annual grass weeds such as cathay, barnyard grass, barnyard grass, dogbane, Euphorbia chinensis and Thrushcross. It has poor control effect on broadleaf weeds.
For example, broadleaf weeds mixed with grass weeds, it can be used after mixing the two medicines. Weeds in soybean and maize fields were controlled by spraying 72% EC with 15-23 mL/100m2 water on the soil surface after sowing and before emergence.
This product is a pre emergence herbicide, mainly used to control grass weeds. The product belongs to 2-chloroacetyl-substituted aniline herbicide, is a cell division inhibitor, used in soil treatment can prevent and control paddy barnyard grass, sedge, felts, duck tongue grass, narrow leaf alisma, etc.
Usually used 3 to 5D before transplanting. It had poor selectivity to wet-transplanted rice when applied alone, and had good selectivity to direct-transplanted rice when used together with pyraxadine. If the mixture was administered with 600 + 200 Gai / ha, the control effect of the mixture was over 90% for the Herba Anemone, Cyperus heterotypus, Cortex acuminatum and Flowering Grass, and 100% for Euphorbia chinensis.
