JaysonOlaytaAssistant Professor I, College of Agriculture, Laguna State Polytechnic University, Siniloan Laguna, PhilippinesThis research was conducted to determine the biopesticidal effects of madre de cacao leaves, marigold plant, makabuhay vines and neem leaves. The experiment was laid out in Randomized Complete Block Design (RCBD) to determine the biopesticidal effect of different extract on tomato. A 416.5 m2 experimental area was divided into 4 blocks. Each block was subdivided into 5 plots with a dimension of 4.5m X 3m or 13.5m2 where the 5 treatments were randomly assigned by draw lots method. A 0.5m was set as distance between plot and 1.0m between block. Thus, each plot has fifty (50) tomato plants were subjected to five treatments: (T1). Control (Commercial pesticide), the botanical plants which were freshly chopped separately, (T2). One kilogram of chopped madre de cacao in two litters of water, (T3). Fifteen grams of chopped makabuhay in two hundred fifty ml of water, (T4). One and a half kilogram of chopped marigold plant in one liter of water (T5) Minitab was used to analyze and interpret data to determine the significant differences among the treatment means. Significant results were subjected to further analysis using Least Significant Differences (LSD). Results revealed that there are high significant differences in the pest incidence per week as to applied with biopesticides. Also, there is a significant difference on the control compared to madre de cacao, marigold plant, makabuhay vines and neem leaves and there is a no significant differences on the mean number of fruits per harvest by week, average weight of fruits at different pesticide.
