Abstract

This study aims to determine the effect of fungal applications Aspergilus niger as a biological agent for controlling soybean pod sucking pests (Riptortus linearis F) in soybean cultivation. This research was conducted for 3 months from February to April 2021. All of these activities were carried out in Sumberjati Village, Silo District, Jember Regency. This study used a non-parametric test with a comparison of two treatments consisting of the fungus Aspergillus niger and the insecticide alphamethrin. The concentration used on the fungus Aspergilus niger was spore density 10⁹ while for the insecticide alphamethrin concentration was 2 ml/l. Analysis of the data using the SPSS application with the Mann-Withney test and to determine the correlation using a simple linear regression test. The results showed that the intensity of attack on thetreatment Aspergillus niger was 3,14% and the intensity of attack on the insecticide alphamethrin was 2,85% which means thet the two treatments are not significantly different. The correlation between attack intensity and yield showed a low effect, withtreatment Aspergillus niger at 10% and in the insecticide alphamethrin treatment at 6%. Keywords: Alphamethrin insecticide, Aspergilus niger, Riptortus linearis F, Soybean.
