Aplikasi Agens Hayati dan Humus untuk Menekan Populasi Fusarium oxysporum f.sp. cubense Penyebab Busuk Batang Pisang
Application of Biological Agent and Humus to Suppress Population Fusarium
oxysporum f.sp. cubense the Cause of Banana Stem Rot.
The study aimed to determine the interaction between P. fluorescens,
Trichoderma spp. fungus, and humus in suppressing the population of Fusarium
oxysporum f.sp. cubense in the soil. The design used was a randomized block
design (RBD) of 2 factors namely antagonistic microbes and humus. There were 18
treatments with 3 replications so that 54 experimental units were obtained. The
variables observed were the population of Foc, population of P. fluorescens,
population of Trichoderma spp., and soil pH. The results showed that the
combination of biological agent and humus could reduce the population of Foc. The
higher concentration of humus combined with biological agent showed the
decreasing population of Foc which causes rot of banana stems.
