Uses: Toxicity: The acute oral LD50 of rats is 3960mg/kg (4500mg/kg), and the acute percutaneous LD50 of rabbits is >2000mg/kg. Mildly irritating to rabbit eyes and irritating to skin. The no-effect dose was 300 mg/kg in the 13-week feeding test for rats, 100 mg/kg in the 2-year feeding test for rats, and 30 mg/kg for mice. No carcinogenic or mutagenic effects were observed.

The LC50 of rainbow trout was 6.6mg/L (96h), and the LC50 of Daphnia was 7.2mg/L (48h). Oral LD50 of quail>2150mg/kg, mallard>5620mg/kg. Chemical properties; This product is a dark amber liquid. b.p.313℃, relative density 1.014(20℃), vapor pressure 10.1×10-3Pa(20℃). It is soluble in most organic solvents, the solubility in water is 63mg/L, and the partition coefficient (n-octanol/water) is 6850. It is stable at ≤145℃, and the half-life of hydrolysis is 30d (25℃) when the pH value is 3～11. Uses; selective systemic conduction type pre-emergence soil treatment agent, belongs to cineole herbicides, can be absorbed by sensitive plant roots, transmitted to the growth points of roots and shoots through xylem, inhibit the growth of meristems and cause them to die. After the agent enters the body of rice, cotton and other crops, it is easily metabolized into hydroxyl compounds, and combined with glycosides in plants to form conjugated compounds and loses toxicity. This product has a wide application period and a small dosage, especially for barnyardgrass control. For example, for the control of barnyardgrass, duck tongue, and ox hair grass in paddy fields, 5-8 days after transplanting seedlings and 1.5-leaf stage of barnyardgrass, use 2-3 mL/100m2 of 10% EC, and use poisonous soil or spray. When spraying, keep the water layer 3 ~ 5cm, water retention 5 ~ 7d. The amount of weeding in dry land should be increased. For example, 82% EC 7.5-12.5mL/100m2 should be used in peanut fields, and soil treatment should be carried out after sowing and before seedlings.
