The Use of an Active Substance Depending on the Application Method of Plant Protection Products: Seed Dressing Versus Foliar Treatment

AbstractThe study into the use of an active substance per hectare was performed to examine three matches of seed dressing fungicides in comparison to foliar applications registered in Poland to protect crops against the same diseases. In each analysed case, the application of an active substance was lower in the case of seed dressing. In the highest instance, an over 34-fold difference was noted in the case of the protection of spring barley against barley net blotch with tebuconazole fungicides.Therefore, in light of integrated pest management requirements concerning the reduction of pesticide use, when the probability of an occurrence of harmful organisms is high and the possibility to replace application methods does exist, the use of seed dressings should be recommended
