FUNGICIDAL COMPOSITION FOR SEED TREATMENT Russian patent published in 2023 - IPC A01N29/04 A01N35/04 A01N37/18 A01N43/30 A01N43/36 A01N43/56 A01N43/653 A01N47/40 A01P3/00 

FIELD: agriculture.

SUBSTANCE: invention relates to a fungicidal composition against fungal pathogenic organisms for the control of crop diseases. The fungicidal composition for dressing seeds contains tebuconazole, prothioconazole, pyraclostrobin and fludioxanil in the amount of 16–26.6 wt.% in the composition as active ingredients, agriculturally acceptable excipients and water up to 100 wt.%. The ratio of active ingredients is, by weight parts: fludioxonil 4.76–37.59, pyraclostrobin 5.64–71.43, prothioconazole 4.76–56.39, and tebuconazole 0.38–19.05. As agriculturally acceptable excipients, the composition contains at least one dispersant and/or emulsifier, defoamer, antifreeze, wetting agent-adhesive, liquid dye, stabilizer-thickener, bactericide, fatty acid methyl esters or vegetable oil, and, optionally, an organic solvent.

EFFECT: proposed fungicidal composition for seed dressing has a high fungicidal activity, which makes it possible to reduce the environmental burden by minimizing the doses of active substances introduced into the environment while maintaining high plant protection efficiency and reduce the degree of resistance due to the synergistic action of four active substances belonging to different groups of chemical compounds.
