EVALUATION OF EFFECTIVENESS OF METHYL THIOPHANATE FOR THE CONTROL OF SOIL-BORNE DISEASES OF TOMATO AND ARTICHOKE In greenhouse pot-experiments, the effectiveness of methyl thiophanate against soil-borne plant pathogens infecting tomato (Fusarium solani, Rhizoctonia solani and Pythium sp.) was compared to that of other fungicides (propamocarb+fosetyl-Al and flutolanil) and biological control agents (Streptomyces griseoviridis strain K61, S. lydicus strain WYEC 108 and Streptomyces sp. strain AtB-42). Moreover, three soil application strategies of methyl thiophanate were evaluated in the control of Verticillium wilt of artichoke. In tomato, treatments with thiophanate-methyl were constantly the most effective, and reduced plant death caused by Pythium sp. by 66%, and by 44-73% the disease severity of Pythium sp., F. solani and R. solani, with variable plant biomass increases. Interestingly, Streptomyces sp. AtB-42 reduced F. solani and R. solani infections by 58% and 54% respectively, thus resulting superior to S. griseoviridis K61. In artichoke, three post-transplanting treatments with 0.65 L/ha of methyl thiophanate, preceded by root-dipping into the fungicide at transplanting, proved to be the best control strategy, and reduced Verticillium wilt by 35-40% while increasing leaf fresh weight by 10%.
