Common name: Mesotrione
Molecular Formula: C14H13NO7S
Registration certification NO. of Mesotrione Tech: PD20131897
Properties:Mesotrione is a trione compound. Melting point: 165.3 ℃ (with decomposition); Vapor pressure (20 ℃): < 5.7x106pa; Solubility in water (20 ℃): 0.16mg/ml; The mass fraction of technical drug ≥ 94%. Its appearance is light brown to sandy opaque solid; Melting point: 148.7 ~ 152.5 ℃, and it begins to decompose at the same time; 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 technical drug is stable when stored at 54 ℃ for 14 days. The appearance of 100g / L nitrosulfuron suspension is light brown to yellowish brown opaque liquid: suspension rate ≥ 70%; Stable for 2 years at room temperature. Chemical name: 2 - (4-methylsulfonyl) - 2-nitrobenzoyl) cyclohexane-1,3-dione.
Application: 100g / L Mesotrione suspension has good control effect on annual broad-leaved weeds and some
gramineous weeds in corn field, such as jute, amaranth, Chenopodium, Polygonum, barnyardgrass, horse Tang, etc. The control effect on iron amaranth and some gramineous weeds was poor. The dosage is 105 ~ 150g (active ingredient) / ha (converted into 100g / LMesotrione suspension, the commercial volume is 70 ~ 100ml / mu, and the general spraying volume is 15 ~ 30L / mu). The method is stem leaf spray. It is safe to use corn once a season at the recommended dose.
Packing: In 25kgs plastic woven bag or small packages according to buyer's requirement.
