Abstract

The invention discloses a sterilizing composition containing boscalid and propamidine. Boscalid and propamidine are active components, and the weight ratio of boscalid to propamidine is 1:1-50:1, and preferably is 5:1-25:1. The active components in the sterilizing composition account for 4%-60% in percent by weight. The dosage form of the sterilizing composition can be missible oil, wettable pulvis, suspending agents, micron emulsions, emulsions in water or water-dispersible granules. The sterilizing composition containing boscalid and propamidine has the characteristics of wide sterilization spectrum, high efficiency, low toxicity, low residue, substantial synergy effect and the like, and is especially beneficial for production of green foodstuffs. The composition is substantially higher in prevention effect than boscalid or propamidine which is used independently, and is capable of reducing application amount of various biologically-active substances, so that the use cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of pesticides, relates to pesticide compounding technology, in particular to a bactericidal composition containing boscalid and propaneamidine. Background technique [0002] Boscalid, chemical name: 2-chloro-N-(4’-chlorodiphenyl-2-yl) nicotinamide, molecular formula: C 18 h 12 Cl 2 N 2 O, relative molecular weight: 343.21, structural formula: [0003] [0004] Boscalid is a new type of nicotinamide fungicide developed by BASF in Germany. It has a wide bactericidal spectrum and preventive effect. It is active against almost all types of fungal diseases. It is effective in preventing and controlling powdery mildew, gray mold and root rot , Sclerotinia, and various rot diseases are very effective, and it is not easy to produce cross-resistance. It is also effective for other chemical-resistant bacteria. It is mainly used for the prevention and control of diseases including rapeseed, grapes, fruit trees, ...
