Mesotrione similar biological activity of pharmaceutical Sulcotrione about 2 times. (2) leaf processing Mesotrione When the 100g/hm on broadleaf weeds up to 90% of the grass weeds up to 70%. Mesotrione stems similar deal about the biological activity of pharmaceutical Sulcotrione 3 times. (3 Mesotrione mixed AtrazinePhysical and chemical properties the original drug to light yellow crystalline powder, melting point 165 °C, density 1.46g/ml (20 °C), vapor pressure 4.27 × 10-8mmHg (20 °C). Soluble in dichloromethane, acetonitrile and acetone, it is a weak acid, pKa3.12 (20 °C), due to its weak acid, so the degree of ionization varies due to pH, water-soluble pH-dependent degree of system, from 2.2 at 20 °C g / L (pH4.8), 15g / L (pH6.9) to 22g / L (pH9.0), pH4 ~ 9  resistance to hydrolysis.ToxicityLD50 in rats (mg/kg) >5000 orally; >2000 dermally; LC50 in rats (mg/l) >5 by inhalation; LC50 (96 hr) in bluegill sunfish, rainbow trout (mg/l) >120, >120Packing According to customer's requirement1.moq100kg2.factory direct3.cas number104206-82-84.samples are available Mesotrione,herbicides agrochemical 95%TCCommon name MesotrioneChemical Name 2-(4-Mesyl-2-nitrobenzoyl)-1,3-cyclohexanedioneCAS NO.104206-82-8M.F.C14H13NO7SMolecular weight 339.32Density 1.46g/ ml (20°C) Boiling Point4.27 ×10-8mmHg (20°C)A.I.

It is weak acid,,pKa3.12(20°C),Solubility in 20°C2.2g/L(pH4.8),15g/L(pH6.9) and 22g/L(pH9.0),anti-hydrolysis in pH4~9.Storage Keep in well-closed containers, in a cool and dark place 0-6°CUsageused to remove weeds in maize fields, it can work with acetochlor and Nicosulfuron.Mesotrionewill be applied pre- and post-emergence through ground or aerial application equipment. Mesotrione has herbicidal activity against broadleaf weeds. It’s efficacy is the result of the inhibition of the enzyme 4-hydroxyphenylpyruvate dioxygenase (HPPD) enzyme in target plants. Following treatment, in sensitive plants carotenoid biosynthesis is disrupted in the chlorophyll pathway, resulting in a bleaching effect.
