\nMolecular Weight: 330.17
\nEINECS Number: 253-178-9
\nMelting Point: 130-134\u00b0C (literature)
\nDensity: 1.6223 (rough estimate)
\nVapor Pressure: 5×10^-7 Pa (25\u00b0C)
\nRefractive Index: 1.6140 (estimate)
\nFlash Point: 2\u00b0C
\nStorage Conditions: Sealed, dry, room temperature
\nSolubility: DMSO 100 mg\/mL (302.87 mM)
\nAcidity Coefficient (pKa): 9.19 \u00b1 0.20 (Predicted)
\nAppearance: Solid, white to off-white
\nWater Solubility: 0.0013 g\/100 mL (Merck 13,5096)
\nBRN: 895003
\nHenry’s Law Constant: 7.1\u00d710^2 mol\/(m3\u00b7Pa) at 25\u2103, Barcelo and Hennion (1997)<\/p>\n
Chemical Properties:
\nPure product is colorless crystals. Melting point about 136\u00b0C, vapor pressure 2.7\u00d710^-5 Pa (20\u00b0C). Solubility in methanol and ethanol is 25 g\/L, in acetone, ethyl benzene, anisole 300 g\/L, in dichloromethane, dimethylformamide, 1-methyl-2-pyrrolidone 500 g\/L, and water solubility is 13 mg\/L (20\u00b0C). Not prone to oxidation, generally stable under normal storage, unstable under alkaline conditions, non-corrosive. Industrial product melting point: 126-130\u00b0C.<\/p>\n
Uses:
\nA broad-spectrum, contact fungicide. Works on spores, mycelium, and sclerotia, inhibiting spore germination and mycelial growth. Almost non-systemic in plants, classified as a protective fungicide. Effective against Botrytis, Sclerotinia, Alternaria, Monilinia, and Corynespora. For controlling tomato early blight, start spraying about 10 days after transplanting: use 50% wettable powder at 11.3-22.5 g\/100 m\u00b2, spray once every 2 weeks for a total of 3-4 times. For gray mold, start before disease onset: use 50% wettable powder at 5 g\/100 m\u00b2, spray every 10-14 days (especially during flowering and fruiting), 3-4 times, improving tomato yield and quality. For seed treatment, use 100-200 g active ingredient per 100 kg of seed to prevent bunt caused by Tilletia species and wheat loose smut. Use 50% wettable powder at 4 g\/L solution to soak potato seed tubers to prevent black scurf caused by Rhizoctonia solani. Onion and garlic bulbs treatment can prevent black rot. Use 50% wettable powder at 11.3-15 g\/100 m\u00b2 during early and full bloom of rapeseed to prevent sclerotinia disease. Alternating or mixing with other fungicides is recommended to avoid resistance.<\/p>\n
Iprodione is a contact fungicide effective against spores and mycelium, controlling diseases caused by Botrytis, Corynespora, Sclerotinia, Monilinia, and Alternaria. It can also be used for seed treatment.<\/p>\n
Broad-spectrum protective fungicide.<\/p>\n
Precautions:
\n[1] Avoid using with strong alkaline agents.
\n[2] Avoid long-term continuous use to prevent resistance; alternate or mix with fungicides of different action.<\/p>\n","protected":false},"excerpt":{"rendered":"
