NIKOLOV, A. and D. GANCHEV, 2011. In vitro antifungal examination of potassium sorbate towards some phytopathogens. Bulg. J. Agric. Sci., 17: 191-194

Potassium sorbate, a common food preservative, was tested under in vitro conditions according to its inhibitory activity towards economically important for Bulgaria phytopathogens. Conidial (germ tube inhibition) and Thornberry (radial growth assays) tests were conducted in order to be determine such activity. The received results showed that potassium sorbate has a potential to be a developed as a protective fungicide against Monilia fructigena, Botrytis cinerea, Rhizoctonia solani, Phytophthora capsici and Alternaria solani.

Key words: potassium sorbate, antifungal activity, phytopathogens
