Fungicidstrategier mod bedemeldug

430-2020, Anne Lisbet Hansen, NBR


Two field trials were carried out to test different fungicide strategies to control powdery mildew (Erysiphe beta) and to minimize fungicide resistance. The treatments included registered products as well as new products including Propulse and Revysol in combination with Comet Pro. Serenade ASO and Kumulus S were also included as alternative products. All fungicide treatments controlled powdery mildew effectively. Kumulus S reduced powdery mildew significantly and comparable to the fungicide solutions. Serenade ASO showed only a low effect on powdery mildew.
