Problems solved by technology

However, the long-term use of a single drug and unreasonable application methods make it easy for pathogenic bacteria to develop drug resistance, resulting in a decrease in drug efficacy and disease outbreaks, which in turn increases drug use, forming a vicious circle, increasing drug costs, and aggravating environmental pollution. It is also a major problem in chemical control

Abstract

The invention discloses a sterilizing composition containing sedaxane and fluazinam. The sterilizing composition comprises an effective component consisting of sedaxane and fluazinam, wherein a proper amount of an agricultural sterilizing auxiliary is added to prepare a common agricultural sterilizing preparation. The sterilizing composition disclosed by the invention has a relative high preventing and treating effect on fungal diseases of crops and the components have an obvious synergic effect; the dosage can be reduced, the ecological damage and environmental pollution can be effectively reduced, and the crop output and quality can be improved. Sedaxane and fluazinam in the sterilizing composition are of low grade toxicity and are safe to human, livestock, beneficial organisms and environment. The sterilizing composition can delay the drug resistance on a single dosage by bacteria.

Description

technical field [0001] The invention belongs to the technical field of pesticides and relates to a fungicide composition. More specifically, it relates to a fungicidal composition containing pyraclostrobin and fluazinam. Background technique [0002] by Rhizoctonia solani ( Rhizoctonia solani ) caused by rhizoctonia is a common disease of major crops. It can cause serious diseases on soybeans, cotton, rice and major vegetables, especially in the seedling stage of crops, causing lack of seedlings and broken ridges, affecting crop yields . by Sclerotinia timidum ( Sclerotium rolfsii ) is a worldwide important disease, and the host plants of this pathogen exceed 500 species. It can cause serious diseases on some main vegetables such as eggplant, tomato, pepper, strawberry, etc. It can also cause large-scale crop necrosis on some economic crops such as peanuts and tobacco, seriously affecting the yield and causing huge economic losses. At present, chemical control is still...
