Abstract

The invention relates to a compounded microbicide. The microbicide comprises effective ingredients and auxiliaries, wherein the effective ingredients comprise phenazin-1-formamide and tebuconazole, the mass ratio of phenazin-1-formamide to tebuconazole is (1 to 20): (1 to 80), and the mass percent of the effective ingredients in the microbicide is 6% to 32%. Compared with the prior art, the microbicide has the advantages that the used effective ingredients are all low in toxicity and have little environmental influence, the two kinds of effective ingredients have an obvious synergistic effect, the generation of resistance to the effective ingredients can be retarded, and the cost of labor of farmers is reduced.

Description

technical field

[0001] The invention relates to the technical field of pesticides, in particular to a compound fungicide. Background technique

[0002] Natural phenazine compounds have a broad-spectrum inhibitory effect on plant pathogenic fungi. Phenazine-1-carboxamide is isolated from the microbial metabolites of Pseudomonas, which can be used for the control of crop diseases, such as phenazine-1-carboxamide against Fusarium, etc. Pathogenic bacteria have a significant inhibitory effect.

[0003] Tebuconazole belongs to triazole systemic fungicides and is a sterol demethylation inhibitor. It is an efficient fungicide used for seed treatment or foliar spraying of important economic crops, and can effectively prevent and control various rusts of cereal crops. , Powdery mildew, net spot, root rot, head blight, smut and seed-borne ring spot, etc.

[0004] Apple spot defoliation disease, also known as brown spot disease, occurs in all apple producing areas and has become the ...
