| Summary, etc. |
A field experiment was conducted to evaluate the effects of different botanical <br/>extracts against aphids on string beans at Barangay 13 Mabanbanag, Vintar, Ilocos <br/>Norte, from January to April 2023. Specifically, it aimed to: 1) evaluate the effect of <br/>different botanical extracts on the growth and yield of string beans; 2) assess the effect <br/>of different botanical extracts in controlling aphids and other pests of string beans; and <br/>3) evaluate the profitability of using botanical extracts in string bean production. The <br/>study was laid out in a Randomized Completely Block Design (RCBD) with three <br/>replications. The treatments included untreated plants, commercial insecticides, chili, <br/>kakawate, and tobacco extracts. <br/>The results showed that the vine length of string bean plants, number of lateral <br/>branches, pod length, and the percentage of marketable and unmarketable pods were <br/>not significantly affected by the application of the different botanical extracts. <br/>However, yield per hectare was significantly higher in plants treated with commercial <br/>insecticide. <br/>During the first and fourth weeks of observation, the botanical insecticides <br/>showed significant effects in aphid infestation. Plants treated with tobacco extract had <br/>the lowest infestation, comparable to those treated with chili and kakawate extracts and <br/>untreated plants. Before the application, all treatments groups experienced moderate <br/>aphid damage, but after application, no damage was noted on the plants. The <br/>application of chili, kakawate, and tobacco extracts had a comparable effect on the <br/>reduction of aphid colonies. <br/>Plants treated with chili extract recorded the highest cost of production at Php <br/>49,275.00. However, it also yielded the highest gross income compared to commercial <br/>insecticide at Php 96,250.00, net income at Php 49,225.00, and return on investment at <br/>104.68%. |
