  White mould is the most important desease of sunflower. We are not able to grow sunflower on the same area for 5-6 years, because of sclerotia. One of the protection methods is if we destroy the sclerotia in the soil with hyperparasite microorganisms, so we can reduce the comeback time of sunflower.

  We carried out our farm size researches through 3 years, with the most important sunflower hybrids of Hungary in the area of Vásárhelyi Róna Kft. We can conclude that the microbiological products (Koni, Trifender, Mico’sol) effect positively on the yield of sunflower hybrids, but the weather (moisture) can significantly modify this effect.
