Efficacy of plant extracts from Reynoutria sachalinensis (F. Schmidt) Nakai against powdery mildew in greenhouse-grown cucumbers (Cucumis sativus L.) was investigated over 3 years under high disease pressure in Greece. In most trials efficacy of the resistance-inducing extracts from R. sachalinensis reached about 90% and was comparable with that of fungicide treatments. In all trials extract-treated cucumbers yielded as many or more fruit per plant as fungicide-treated plants. R. sachalinensis extract applications enhanced yield up to 49% over the control. The results demonstrate the potency of R. sachalinensis plant extracts as effective plant protecting agents even under the high disease pressure prevailing in the Mediterranean region.
