2. The control of gray mold disease before the onset of the drug, with 50% wettable powder 5g/100m2, every 10 ~ 14d spray once (flowering, fruiting period is preferable), a total of 3 ~ 4 times, can improve the yield and quality of tomatoes.

3. Seed treatment with 100 ~ 200g of the original medicine per 100 kg of seeds has a control effect on smut caused by Verminium graminis and Megalomelus triticum.

4. Using 50% wettable powder to prepare 4g/L concentration of medicinal solution to soak potato seed potatoes, isomylurea has a preventive effect on the nigrosis caused by rhizoctonia.

2. Can not be mixed with strong alkaline or acidic agents.

3. In order to prevent the emergence of resistant strains, the application times of Iprodione in the whole growth period of crops should be controlled within 3 times, and the best results can be obtained when the disease is used at the early stage and before the peak.
