Preliminary evaluation on the effect of different botanical pesticides against selected pests of rice (Oryza sativa Linn.)

Abstract

This study was conducted at Capiz State University, Burias Campus, from December 08 to 24, 2016 to evaluate the effect of different botanical pesticides against selected pests of rice. The study was laid out in a Completely Randomized Design (CRD) with eight (8) treatments replicated three (3) times. The data gathered includes the behavior and mortality of the insect pests. All data were subjected to the Analysis of Variance using F-test and the results were interpreted at 5% level of significance. Differences were compared using Duncan’s Multiple Range Test (DMRT). As the concentration of botanical crude extract increases the mortality of the test organisms also increases, but when the concentration of botanical crude extract decreases the mortality of the test organisms also decreases. Golden apple snail treated with 50% to 100% hagonoy and tubli extract had the highest mortality rate while June beetle treated with 75% to 100% balanti extract gave the highest mortality rate. For red ants treated with 50% to 100% tubli extract obtained the highest mortality rate while rice bug treated wih 50% to 100% badiang extract obtained the second highest mortality with that of the commercial pesticide
