Verification Trial of Botanical Pesticides as Control Agents Against Pests of Eggplant (Solanum melongena)
by Open Science Repository Agriculture
Study was conducted on February 2012 to May 2012 at the IFSU Experimental Area, Nayon, Lamut, Ifugao, to verify the effectiveness of botanical pesticides as control agents against pests of eggplant (Solanum melongena
The botanicals were collected, pounded into a pulp, mixed with water, and then filtered to produce a stock solution. This solution was then diluted with water and applied to the plants by conventional spraying using a knapsack sprayer. The botanicals were applied on the eggplants at weekly intervals starting from transplanting until a week prior to harvesting.
The effectiveness of the botanicals was established using the randomized complete block design as experimental design with three treatments, replicated four times. The treatments were: kakawate leaves (T1), neem leaf and fruit (T2), and makabuhay (T3) extracts with the synthetic pesticide (T0) treatment as the control.
Results of the study shows that the highest reduction of pest is from kakawate extract (T2) followed by makabuhay extract (T3) and synthetic pesticide (T0). Neem extract (T2) has the lowest number of pest reduction. Furthermore, the most common eggplant pest is aphids, with an average weekly incidence of 573. Keywords:
