Abstract

  Dimethomorph is a systemic fungicide utilized within Indonesian agricultural sector. Inappropriate application of dimethomorph fungicide may result in environmental contamination and the development of resistance among rhizosphere microorganisms. This study aims to ascertain the responses of rhizosphere microbial isolates to dimethomorph fungicide, thereby providing critical insights for evaluating the efficacy of this fungicide against rhizosphere microbes. Such information is essential for formulating plant pest and disease management strategies that utilize more suitable and sustainable dosages. The investigation involved testing bacterial isolates MR-B01, MR-B02, MR-B03, MR-B04, and fungal isolate MR-F01 against dimethomorph fungicide employing the agar diffusion method with disc paper. The experimental design incorporated a treatment factor with five variation concentrations of dimethomorph fungicide (0 g/L, 0.5 g/L, 1 g/L, 1.5 g/L, and 2 g/L), executed with ten repetitions. The findings indicated that varying concentrations of dimethomorph fungicide exhibited distinct effects on the resistance of the tested microbial isolates, specifically bacteria MR-B01, MR-B02, MR-B03, MR-B04, and fungal isolate MR-F01.
