The vapor pressure is 0.0267mPa (25℃), and the distribution coefficient KowlogP=4.47 (25℃). Solubility in water: 0.116 mg/L (25°C). Solubility in other solvents (g/100g, 20℃): acetone 72.5, chloroform 50～55, cyclohexanone 61.5, dimethylformamide>50. Stability: >240 ℃ decomposition. pH5～9(25℃), no obvious hydrolysis in 28d.

Toxicity:

Rat acute oral LD50>5000mg/kg, rabbit acute percutaneous LD50>10000mg/kg. It is mildly irritating to rabbit skin and moderately irritating to rabbit eyes, but it disappears in a short time. Rats acutely inhaled air with LC50 (4h)>5.4mg/L. The no-effect dose for rats (2a) was 40 mg/kg feed, the no-effect dose for mice (2a) was 2 mg/kg feed, and the non-effect dose for dogs (2a) was 100 mg/kg feed. ADI value 0.0003mg/kg. No teratogenic, mutagenic or carcinogenic effects were found in animals within the test dose. No abnormality was seen in the three-generation reproduction test and the delayed neurotoxicity test. Low toxicity to birds, LD50>2150mg/kg of quail. Wild ducks and quails were fed with LC50(8d)>5000mg/L. Highly toxic to fish and some aquatic animals, LC50 (mg/L): 0.41 for rainbow trout and 0.2 for sunfish. High toxicity to grass shrimp, LC50 is 0.018mg/L, low toxicity to crab, LD50 is 320mg/L, low toxicity to bees, acute oral LC50 is 0.025mg/piece.

Application:

A contact herbicide that kills weeds in the presence of light. It mainly enters the plant through the coleoptile and mesocotyl, and is absorbed less by the roots, and a trace amount is transported upward through the roots and sent to the leaves. Pre-emergence and post-emergence application to control annual broadleaf weeds and grass weeds on various tropical and subtropical crops, especially fruit trees (including citrus), grapes, nuts, cereals, corn, soybeans, peanuts, rice, cotton, Bananas, mint, onions, garlic, ornamental trees and bushes, and pine seedbeds.
