Aspects regarding the control of pathogens on tomato crops under high plastic tunnels

Abstract

In the year 2020, at RDIVFG Vidra, an experiment with tomatoes was set up under high plastic tunnels, in order to study the efficacy of some combinations of fungicides in the control of pathogens. The Prekos F1 tomato hybrid was used. The experience included 5 variants in 4 replications. The experimental variants were the following: V1. Signum 0.15 +Cabrio Top 0.2%; V2. Ortiva Top 0.1% + Switch 0.1%; V3. Cidely Top 0.1% + Prolectus 0.12%; V4. Dagonis 0.1% + Teldor 0.08%; V5. Untreated control. The pathogens present in the tomato crop were Alternaria solani (early blight), Botrytis cinerea (grey mold) and Fulvia fulva (leaf mold). The efficacy of the products combinations was assessed according with the average degree of attack and the obtained yield, which was processed by the variance analysis method.
