Thidiazuron

Chemical properties: Pure white odorless and tasteless crystalline solid. m.p. (decomposed at 210 ~ 212.5 ℃ (decomposed at 217 ℃), vapor pressure 4×10-9Pa) (25 ℃).

Solubility at 25 ℃ is: dimethyl sulfoxide >500g/L, dimethylformamide >500g/L, cyclohexanone 21.5g/L, acetone 8g/L, methanol 4.5g/L, ethyl acetate 0.8g/L, hexane 6mg/L, insoluble in aliphatic and aromatic hydrocarbons, solubility in water 31mg/L. The partition coefficient was 59 (pH=7.3). Stable below 200℃; It is stable to water at room temperature, half-life >24 days; The half-life in soil was <60d.

Ureas plant growth regulators with cytokinin activity. It is mainly used as cotton defoliant, and can also be used for apple tree, grape tree, Hibiscus defoliate and phaseolus bean, soybean, peanut and other crops. There was a significant inhibitory effect, and the dosage was 0.3 to 3kg/hm2. If the cotton field dosage is 0.5kg/hm2, the drug is used when 50% ~ 60% of the cotton peach is opened, the preparation is diluted into an aqueous solution of 500L/hm2 and sprayed on the plant, and the defoliation effect is 98%. It can also be used to control weeds such as barnyardgrass, Setaria, Matang, Malonnax, creeping Crisporium, and Plagues, with an dosage of 3kg/hm2, and the control effect is nearly 100%.
