Abstract
The invention discloses a bactericidal composition, a bactericidal pesticide and application of the composition and the pesticide. The composition comprises thifluzamide and azoxystrobin of which the weight ratio is (10:1) to (1:10). The pesticide comprises the composition used as an effective component of the pesticide and auxiliary components of the pesticide. The invention further provides application of the composition to the control of rice sheath blight disease. Compared with a single dosage, the bactericidal composition has a remarkable synergistic effect on the disease, improves the disinfection effect, reduces pesticide use times, reduces pesticide use cost, and reduces environmental pollution and pesticide residue; as the composition comprises effective components with different modes of actions, action sites are increased, which is conducive to eliminating and delay of the generation of drug resistance of germs.
Description
technical field [0001] The invention relates to an agricultural bactericidal composition, in particular to a bactericidal composition, bactericidal pesticide and application thereof. Background technique [0002] Thiofuramide, belonging to the thiazole amide fungicides, has strong systemic conductivity and long-lasting effect. Thiofuramide is a succinate dehydrogenase inhibitor. Due to its fluorine content, it has strong competitiveness in biochemical processes, and it is not easy to recover once combined with substrates or enzymes. Thiofuramide is used in rice, cereal crops and turf, and is effective against pathogenic fungi such as Rhizoctonia, Puccinia, Tilletia, Phenibacterium, and Ustilago, especially for Basidiomycetes Diseases caused by fungi, such as sheath blight and blight, have special effects. Under the recommended dosage, it is safe to crops and has no phytotoxicity. [0003] Azoxystrobin is the first commercialized methoxyacrylate fungicide, which has a broa...
