| Summary: | This investigation sought to determine the effect of four drip irrigation sheets on the incidence of Prodiplosis Longifila in the tomato crop. It was carried out during the dry season from May to September 2018 in La Venturita del Cantón Bolívar, Province of Manabí. Irrigation sheets were studied with variations of evapotranspiration percentage. Treatment 1: drip irrigation sheet at 80% ETc; Treatment 2: drip irrigation sheet at 100% ETc; Treatment 3: drip irrigation sheet at 120% ETc and 78% (Control). A completely randomized design (CRD) was used, with four treatments and six repetitions. The climatic data of evaporation and precipitation were taken daily from the Agrometeorological Station of ESPAM and the electrical conductivity of the soil and water carried out in the INIAP "Pichilingue". With this information the irrigation calculation for the different sheets and phenological stages was made. The results allow determining that with the application of the 100% ETc irrigation sheet, the lowest infestation of P. longifila was recorded accompanied by a rational program of pesticides, with 11 applications of different kind of substances, compared to 30 to 35 applications commonly carried out by farmers.
