Abstract

The invention provides a prothioconazole dispersible oil suspension agent which is prepared from the following components in percent by weight: 10-40% of prothioconazole, 2-10% of an emulsifier, 2-8%of a polycarboxylate dispersant, 0.5-6% of a viscosity regulator, 0.1-1% of a defoamer and the balance oil. The viscosity regulator is a mixture of organobentonite and fumed silica. The prothioconazole dispersible oil suspension agent is stable in performance. Compare with a missible oil preparation, use of an organic solvent is reduced, so that the suspension agent is more environment and safer,safe to store and convey and use, is environment-friendly and meets the development direction of current pesticide preparations. Compared with a water suspension agent, the prothioconazole dispersibleoil suspension agent is more stable in performance and long in effective period, and prevents a phenomenon that a water suspended product is precipitated severely. The prothioconazole dispersible oilsuspension agent is high in stability, meets the demands on different water quality areas, high altitude areas, low temperature areas and equator near high temperature areas, and also reduces the influence of the organic solvent to the environment.

Description

technical field [0001] The invention relates to the technical field of fungicides, in particular to a prothioconazole dispersible oil suspension. Background technique [0002] Prothioconazole is a new broad-spectrum triazolethione fungicide discovered, developed and produced by Bayer Crop Science. Prothioconazole is a sterol demethylation (ergosterol biosynthesis) inhibitor, which not only has a good systemic effect, excellent protection, treatment and eradication activities, but also has a long duration of action. The results of a large number of field efficacy tests show that prothioconazole is safe for crops, has good effects in disease prevention and treatment, and increases yield significantly. Prothioconazole is mainly used to prevent and control diseases on crops such as wheat, barley, rapeseed, peanut, rice, bean crops, sugar beet and field vegetables. Compared with triazole fungicides, prothioconazole has a broader bactericidal spectrum. It has a good control eff...
