Introduction:Validamycin is a systemic fungicide for agriculture use to control rice sheath blight, wheat sheath blight as well as Rhizoctonia disease from corn,cotton vegetable and so on. It can be absorbed by the cells of the pathogenic fungus as nutrilite and transmitted through the hypha, whose growth are affected when contacting with the active ingredient, which make the hyphal top abnormal and inhibit the growth of the hypha. through inhibiting the synthesis of inositol which is the essential for the growth of fungi. Validamycin is non-pollute and residue to environment, it is widely used in the crop diseases control.

Use：The main control Rhizoctonia solani, Sclerotinia sclerotiorum wheat, corn leaf diseases, Blight vegetables, cotton, beans Blight, BAI Juan disease, such as ginseng Blight.
Application：Biochemistry Inhibitor of trehalase, an enzyme which mediates the digestion of the carbohydrate trehalose and transport of glucose to the hyphals tips. Mode of action Non-systemic antibiotic with fungistatic action. Causes abnormal branching of the tips of the pathogen, followed by cessation of further development. Uses Control of Rhizoctonia solani in rice, potatoes, vegetables, strawberries, tobacco, ginger and other crops; damping-off diseases of cotton, rice and sugar beet, etc. Applied as a foliar spray, soil drench, seed dressing, or by soil incorporation, at 1.25-1.56 g/ha (liquid), 9-12 g/ha (DL formulation), and 0.090 mg/kg (DL or seed dressing).
