Mycoflora potential in rhizospher as biological agents to control wilt diseases on papper plant (Capsicup frutescens L. )

The cause of wilt disease in pepper is Phytophthora capsici fungi, which attacked the pepper plantation area in Kertalangu Village, East Denpasar Sub-district, Denpasar-Bali. The results showed that the fungi on conducive soil were Phytophthora sp., Aspergillus sp., and Neurospora sp. with the highest prevalence attained by Neurospora sp. of 80%, while on suppressive soil found mycellia sterillia fungus, Fusarium sp., Neurospora sp. Aspergillus sp., Penicillium sp., Mucor sp., and Trichoderma sp. with the highest prevalence achieved by Penicillium sp. by 27%. The antagonistic fungus found only in suppressive soils is the fungus Neurospora sp., Trichoderma sp., Aspergillus sp., Penicillium sp., and Mucor sp. each with a percentage of resistance of 67.78 ± 1.6%, 68.52 ± 2.62%, 75.93 ± 2.62%, 68.77 ± 5.43%; and 67.59 ± 3.82%. The highest inhibition ability is achieved by Aspergillus sp. Keywords: wilt disease, suppressive soil, conducive soil, antagonist, and inhibition ability.
