Abstract:

Late blight (Phytophthora infestans) is one of the most devastating diseases of potato and
tomato. It can result in complete destruction of these crops. The aim of this study was to test
alternatives to synthetic fungicides currently used in the control of late blight and to evaluate the
efficacy of a combined use of biocontrol agents and natural products. Antifungal activities of the
BCAs Trichoderma harzianum T39 (formulated), four yeast and five bacteria isolates from Israel and
Italy were assayed on tomato and potato plants artificially inoculated with P. infestans sporangia,
under growth chamber and greenhouse conditions. Additionally we tested the effect of an alcoholic
plant extract (Elot-vis), a chitosan based product (Chitoplant) and a fatty acid based agent (Tecnobiol)
compared to two low copper rate products (Labicuper and Labimethyl) and copper hydroxide
(Kocide). Significant control of the disease on tomato was observed following treatments with T.
harzianum T39, two bacteria isolates (B19 and B69), Chitoplant and Elot-vis. T. harzianum T39, Elotvis
and Chitoplant were consistent in their control activity. The tests in potato consisted only of the
BCAs. T39 and B19 significantly reduced potato late blight. In tomato a synergistic effect was
obtained for B19 plus Elot-vis.
