Effectiveness of the Vegetable Insecticide Ajeran (Bidens pilosa) Against Aphids (Aphis glycines) on Soybean Plants

Abstract

Pests make it hard to get more soybeans. This study aims to see if a vegetable insecticide (Bidens pilosa) can control aphids (Aphis glycines) using organic products. This research was done from November 2022 to February 2023 at the Jember State Polytechnic Campus. This study used a 5-treatment, 4-replication, non-factorial completely randomized design with 20 experimental units. The treatments were different levels of Ajeran weed leaf juice: 0%, 5%, 10%, 15%, and 20%. Non-parametric data analysis using the Shapiro-Wilk test. Levene test for data homogeneity. Further tests used the Independent Sample T-Test or Mann-Whitney non-parametric test. The 20% Ajeran concentration killed 84% of the aphids. Ajan vegetable insecticide is 84% effective. Aphid infestation on soybean plants varies. At the last stage of application, it has the same value of 0.11. Treating vegetables with insecticides has better results than using chemical pesticides.
