Abstract
Streptomyces sp. and Trichoderma sp. are soil microorganisms isolated from shallot fields that can act as biological agents and increase crop production. Nezara viridula, the southern green stink bug, is the leading pest of soybean during the generative period, which can cause damage up to 80%. This study aimed to determine the efficacy of a liquid biopesticide formula using a mixture of coconut water and potato extract containing Streptomyces sp. and Trichoderma sp. This study used a randomized block design. The first factor was the time of application and the second factor was the concentration level. There were 8 treatment combinations and 2 controls. Each treatment combination was repeated three times. Probit LC50 and LT50 were performed to determine the effectiveness of biopesticides. The calculation of probit analysis obtained results of 84,443 ppm or about 84% for LC50, while the LT50 analysis obtained results of 4.7 days.
