Abstract

The invention relates to a methyl sulcotrione oil suspension concentrate combination which is characterized by comprising the following components by weight percent: 5 percent to 25 percent of methylsulcotrione, 1 percent to 10 percent of emulsifier, 2 percent to 6 percent of wetting dispersant, 1 percent to 5 percent of suspension stabilizer, 1 percent to 5 percent of antifreezer, 0 percent to 0.2 percent of organosilicon defoamer and vegetable oil up to 100%. The vegetable oil is at least one of jatropha curcas oil methyl and jatropha curcas oil. The methyl sulcotrione oil suspension concentrate adopts inedible vegetable oil which has wide sources as a suspended carrier, and has the advantages of non competition for food with people, high safety and low cost. A formula applies a novel high-efficiency multifunctional agent such as lignosulfonate grafted with polymers, polycarboxylate, polymer carboxylate with rosin and the like, and has high suspensibility.

Description

technical field [0001] The invention relates to a pesticide preparation, in particular to a mesotrione oil suspension. Background technique [0002] Mesotrione (chemical name: 2-(4-methylsulfonyl-2-nitrobenzoyl)cyclohexane-1,3-dione), also known as mesotrione, is an effective control It is a herbicide for pre-emergent and post-emergent broadleaf weeds and some grass weeds in corn field, with systemic property. Mesotrione has the characteristics of rapid degradation in soil, low dosage, no residue when crops are harvested, safe for subsequent crops, and no pollution to groundwater and surface water. At present, the dosage forms of mesotrione produced and used are suspension concentrate and water preparation, and there are also patent applications for oil suspension (for example, patent application 200510047057.8, a kind of mesotrione oil suspension). [0003] In patent application 200510047057.8, the vegetable oil used in mesotrione oil suspension and the vegetable oil used...
