What is Diclobutrazol?

Chemical properties

Diclobutrazol is a white crystal. Soluble in acetone, chlorine, methanol, ethanol and other organic solvents; slightly soluble in water, the solubility in water is 9mg/L. It is stable to acid, alkali, light and heat. Under the condition of strong acid and alkali, the hydrolysis half-life is 5d at 80℃. Under the condition of pH value of 4~9, its aqueous solution is stable to natural light for more than 33d. At 50℃, 37℃ Under the conditions, the stability of the original drug is above 90d and 182d, respectively.

The Uses of Diclobutrazol

Diclobutrazol, a systemic fungicide, is highly active against rusts, powdery mildews, and other fungal phytopathogens. Diclobutrazol can be used as a pesticide to control of various crop diseases, such as powdery mildew, smut of wheat, sheath blight of rice, etc.
