Fungicidal composition containing tiadinil and triazole fungicide

Abstract

The invention discloses a fungicidal composition containing tiadinil and a triazole fungicide. The fungicidal composition contains an active ingredient A and an active ingredient B. The active ingredient A is tiadinil. The active ingredient B is a triazole fungicide. The triazole fungicide is selected from any of the following compounds: tebuconazole, tricyclazole, tetraconazole, flutriafol, cyproconazole, penconazole, flusilazole, prothioconazole, hexaconazole, epoxiconazole, difenoconazole, triflumizole and propiconazole. The weight ratio of the active ingredient A to the active ingredient B is 1:60-80:1. The composition has high activity to multiple diseases of multiple crops, has obvious synergistic effects, expands the fungicidal spectrum, and has advantages of small dosage, resistance to rainwater washing and obvious synergism.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a fungicidal composition containing thiazil and triazoles on crop diseases. technical background [0002] Tiadinil chemical name: 3'-chloro-4',4'-dimethyl-1,2,3-thiadiazole-5-carboxanilide, molecular formula: C 11 h 10 ClN 3 OS. The agent itself has relatively poor inhibitory activity against pathogenic bacteria, and its mechanism of action is mainly to prevent pathogenic hyphae from invading adjacent healthy cells and induce the production of disease-resistant genes. The agent has good systemic properties, can be absorbed through the roots, and can be quickly transmitted to other parts. It is suitable for use on the water surface, has a long lasting effect, and has a good control effect on leaf blast and ear blast. [0003] Triazole fungicides have broad-spectrum sterilization—high activity against many kinds of pathogenic fungi such as Ascomycetes, Basid...
