STUDIES ON THE IMPACT OF PAEONIA SUFFRUTICOSA AND HEDERA HELIX EXTRACTS ON PHYTOPHTHORA INFESTANS AND PSEUDOPERONOSPORA CUBENSIS ZOOSPORE RELEASE AND GERMINATION PUBLISHED

Alin Cărăbeţ, Karl Fritz Lauer
In this paper, we studied the influence of some plant extracts upon Phytophthora infestans and Pseudoperonospora cubensis zoospores releasing and germination. We have tested the extracts obtained from Paeonia suffruticosa and Hedera helix macerated in acetone in different concentrations. There was observed the inhibition of zoospores releasing and germination.
