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 bactericidal composition containing penflufen and thifluzamide. The bactericidal composition contains an effective component prepared from penflufen and thifluzamide and is prepared into a common agricultural bactericide dose form by adding a proper amount of an agricultural bactericide aid. The bactericidal composition has relatively high prevention and control effects on fungal diseases of crops, and an obvious synergistic effect is achieved between two medicaments; the dosage can be reduced, the ecological damage and the environmental pollution can be effectively reduced, and the yield and the quality of the crops can be improved; penflufen and thifluzamide have low toxicities and are safe to human and livestock, beneficial organisms and environments; the drug resistance of germs to the single medicament can be delayed.

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 of flufenadin and thifuramide. Background technique [0002] 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 major vegetables such as eggplant, tomato, pepper, strawberry, etc. It can also cause large-scale crop necrosis on some oil-bearing economic crops such as soybeans, peanuts, and tobacco, seriously affecting production and causing huge economic losses. . 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 . At present, chemica...
