【 Physical and Chemical Properties】: Nitrosulfurone is a ketone compound. Melting point: 165.3 ℃ (with decomposition); Vapor pressure (20 ℃):< 5.7x10-6pa； Solubility in water (20 ℃): 0.16mg/mL; The mass fraction of the raw material is ≥ 94%. Its appearance is a light brown to sandy opaque solid; Melting point: 148.7~152.5 ℃, and decomposition begins simultaneously; Solubility (g/L): 1.4 in xylene and 2.7 in toluene. 3.6 in methanol and 76.4 in acetone; 82.7 in dichloromethane and 96.1 in acetonitrile; Thermal storage stability: The raw material has stable properties after being stored at 54 ℃ for 14 days. The appearance of the suspension of 100 g/L nitrosulfuron is a light brown to yellow brown opaque liquid with a suspension rate of ≥ 70%; Stable storage at room temperature for 2 years. Chemical name: 2- (4-methylsulfonyl) -2-nitrobenzoyl) cyclohexane-1,3-dione.

【 Application Technology 】: A suspension of 100 g/L nitrosulfuron methyl has a good control effect on annual broad-leaved weeds and some grasses in corn fields, such as Abutilon, Amaranth, Quinoa, Polygonum, Echinochloa crus, and Malvaceae. However, the control effect on amaranth and some grass weeds is relatively poor. The dosage is 105-150g (Active ingredient)/ha (converted to 100g/L of nitrosulfuron suspension), and the commercial quantity is 70-100mL/acre. The general spraying volume is 15-30L/acre. The application method is stem and leaf spray. Using corn once a season is safe for corn at the recommended dosage.
