Flusilazole, penconazole and triadimefon proved antisporulant activity against Podosphaera leucotricha fungus.
The most effective in the control of apple scab appeared: LS 840608 and flusilazole and also bitertanol, etaconazole, penconazole, myclobutanil, triflumizole. All these compounds showed after-infection activity: bitertanol, myclobutanil, penconazole and triflumizole up to 3 days, etaconazole up to 4 days, flusilazole up to 6 days and LS 840608 up to 8 days after infection
The effect of some endogenic substances contained in the cortical parenchyma of apple trees on growth in vitro of the fungus Phytophthora cactorum (Leb. of Cohn) Schroeter
Gel filtration of an alkaline extract of the cortical parenchyma yielded four fractions of which two had activity in vitro on the growth of Phytophthora cactorum. Fraction I was stimulatory and fraction IV inhibitory; one of the inhibitors in fraction IV was identified as phloridzin. When the extraction solvent contained sodium sulphite in addition to sodium hydroxide, fraction II showed inhibitory activity
