Abstract
Considering the cost, health and environment hazards of synthetic pesticides, there is a need to find and develop practical, safe and effective alternatives. The study aimed to determine the biopesticidal effects of Gliricidia sepium and Tinospora rumpii extracts on Eruca sativa under different frequency of application. A 4 × 3 factorial experiment in Split Plot Design in Randomized Complete Block Design (RCBD) was used in the study. Data obtained was analyzed using STAR. Significant results were subjected to further analysis using Least Significant Differences (LSD). Sensory evaluation was analyzed using Duncan’s Multiple Range Test (DMRT). Results revealed that different pesticides used in the study have significantly affected the width of leaves, shoot root ratio, biological, economic yields and sensory evaluation. No significant differences were noted on the biopesticide and frequencies observed in the parameters used in the study. The population of green peach aphids and striped flea beetles declined on the plants sprayed with the botanical extracts and commercial pesticide noticed on Eruca sativa sprayed with Tinospora rumpii extract thrice a week. The application of fermented makabuhay extract twice a week is the most economical for arugula production. The untreated plants stood out in terms of odor, crispiness, taste and passed the preferences of the respondents, while the commercial pesticide obtained the highest score average in terms of appearance and aftertaste. Twice a week application of fermented makabuhay extract is recommended for high yield and net income.
