In laboratory and small-field experiments inducers of synthetic origin: benzothiadiazole (BTH), salicylic acid, and inducers of biological origin: glycine betaine, extracts prepared from oak bark (Quercus robur L.), Reynoutria sacchaliensis L., curcuma (Curcuma longa L.), ginger (Zingiber officinale Roscoe) were effective against powdery mildew on the winter wheat (cv. Kanzler) susceptible to this disease. All studied inducers slightly effected the synthesis of new proteins (PR-proteins)
