Abstract

The study focused on the economic profitability of the utilization of homemade organic pesticide for small scale production of Brassica napus L. varchinensis (Pechay). An experiment was undertaken at the Palayamanan Program at the University of Eastern Philippines to determine the effectiveness of homemade organic pesticide in controlling or preventing insect infestation in Pechay, to find out the effective level of this homemade pesticide and to determine the economic profitability of using homemade organic pesticide and insecticide. To explore the use of homemade extract from garlic, Allium sativum L., hot pepper, Capsicum frutescens L., vinegar and mineral oil in the management of insect pests of Pechay. The design used was the randomized complete block design (RCBD) and the data gathered were statistically analyzed using ANOVA and DMRT at 5% level of significant. There were five treatments made up of 50% extracted organic insecticide diluted in 500ml and 1 litter of water treatment before the insects will attack (pre–treatment) in weekly intervals and separate application of the same formulation of the treatment after the insect will attack (post-treatment) two days interval and control without any treatment. The result of the study showed that those that gained higher profitable weight in treatment plots were the post – treatment.
