Embodiment 150

[0082] Example 150% Flusilazole Tridemorph WP WP Control Efficacy Test of Wheat Powdery Mildew

[0083] Flusilazole 20%, tridemorpholine 30%, polycarboxylate 4%, sodium lauryl sulfate 3%, silkworm excrement 2%, white carbon black 25%, diatomaceous earth is added to 100%, and the mixture is Jet pulverization to obtain 50% flusilazole · tridemorpholine wettable powder. The proportion is diluted and sprayed at 40 g / mu, sprayed at the early stage of the disease, sprayed once every 7 days, and sprayed twice in total. 7 days and 14 days after the last spraying, the disease index was investigated and the control effect was calculated. 7 days and 14 days after the application, the effects of preventing and treating wheat powdery mildew were 91.6%, 96.2%, respectively. The 40% flusilazole EC and the 750g / L tridemorph EC followed the same method, respectively at 15 g / mu and 30 g / mu Diluted and used, the control effects were 64.2% and 71.6% 14 days after treatment.

Abstract

The invention discloses a germicide composition. The composition comprises synergistic effective amount of tridemorph and one of triazole germicides including propiconazole, penconazole, myclobutanil, epoxiconazole and flusilazole, wherein the weight part ratio of the two active ingredients in the germicide composition is 50:1-1:50. The germicide composition of the invention at least comprises one surfactant, so that the active ingredients are dispersed in water when the germicide composition is applied. The germicide composition of the invention has protective activity, curative activity and uprooting activity and can be used for various crops such as wheat, paddy, vegetables, fruit trees and the like and preventing and treating plant diseases caused by pathogenic bacteria of aseomycotina, basidiomycolina and deuteromycotina.

Description

technical field [0001] The invention belongs to the field of agricultural fungicides, and relates to the preparation and application of a fungicidal composition containing tridemorpholine. Background technique [0002] Tridemorph is a morpholine fungicide. Molecular formula is C 19 h 39 NO (approximately), chemical name: 2,6-dimethyl-4-tridecylmorpholine. [0003] Structural formula: [0004] Tridemorph is a broad-spectrum systemic fungicide with protective and therapeutic effects, which can be absorbed by the roots, stems and leaves of plants, and is effective against various plant diseases caused by basidiomycetes, ascomycetes and half-knowledge fungi. It mainly inhibits the biosynthesis of ergosterol in pathogenic bacteria. [0005] Long-term use of a single dose of trimorpholine can easily lead to drug resistance in diseases, leading to problems such as increased dosage, reduced control effect, and shortened duration, which is not conducive to sustainable developm...
