Efficacy Evaluation of Selected Biorational Combination in the Management of Tomato Blight.

Abstract

KAMOGA GERALD (2011-M152-20007) Efficacy Evaluation of Selected Biorational Combination in the Management of Tomato Blight This experiment was conducted in Katabi sub-county in Wakiso district. The topic was: Efficacy evaluation of selected biorational combinations in the management of tomato blight. These biorationals were picked from the locally used plant materials used as natural pesticides. They included Carica papaya, Phytolacca dodecandra, Jatropha curcas, Capsella Bursa-pastoris and Tephrosia vogelli.This research was guided by two major objectives that is; to determine the biorational combinations that reduces tomato blight to levels below economic injury thresholds and to establish the optimum concentration of biorationals used in controlling tomato blight. This research used a completely randomised research design in which three treatments were made at varying biorational concentrations (25%, 50%, and 75%). The data were collected from all treatments and efficacies for each treatment evaluated. It was established that treatments of Carica papaya with Phytolacca dodecandra were more effective in managing tomato blight below economic injury thresholds. This research recommended that Carica papaya with Phytolacca dodecandra should be used by farmers in the management of tomato blight. Key words: Blight, Tomato, Efficacy
