Utilization of bio-insecticides on tomato cutworm, armyworm, leafminer and fruitworm larvae
(Don Mariano Marcos Memorial State University - North La Union Campus, 2016-03) Casilla, Gerald C.
This study was conducted in support to Republic act No.10063 known as Organic Agriculture Act of 2010 in providing ecologically sound, socially acceptable, economically viable and technically feasible pest management strategies, for sustainable agriculture, particularly in tomato vegetable production with the following treatments; T0 - Control (No spray), T1 - Chemical insecticides, T2 - Lantana leaves, T3 - Lemon grass, T4 - Makabuhay stems, and T5 - Marigold leaves. The Completely Randomized Design (CRD) with three replications was used in the study and it was conducted inside the greenhouse condition. Based on the findings of the study, all the botanical sprays or bio insecticides were comparably effective with chemical insecticide spray on the control of tomato foliage insects, namely cutworm, armyworm and leaf miners in terms of the percent number and degree of leaflets damage. If lantana is not available in the vicinity, lemon grass and makabuhay stems in the vicinity can be used as capable substitute of the chemical insecticides.
