- Abstract
The effect of biocompatible products on the growth of cucumber powdery mildew (Sphaerotheca fuliginea) was evaluated. Plants were treated with dispersions or solutions of sunflower, olive and neem oils and potassium bicarbonate, potassium silicate and monopotassium phosphate, and compared with azoxystrobim. The most effective treatments for reducing the severity of powdery mildew damage in the cucumber foliage were those that contained the higher doses of potassium silicate, potassium bicarbonate, olive oil, monopotassium phosphate and neem oil showed a disease severity similar to azoxystrobin. Potassium bicarbonate, potassium silicate and oils were phytotoxic. Disease control was worse on climatic conditions with higher temperatures.
