Relevant species are P. infestans (causing potato late blight) and P. capsici (causing blight in pepper). In recent years, the use of conventional fungicides has favoured the appearance of different resistant strains. This study analyses the effect of various compounds on these two Phytophthora species. Those compounds were designed on the basis of known structures of natural compounds to obtain a rational control of these fungal-like species. All the analysed products showed a fungistatic activity against both strains, one of them reduced mycelial growth by over 46% at 100 p.p.m. Keywords phytophthora infestans phytophthora capsici percentage of inhibition rational fungicides fungistatics
