Abstract

Desease that often occurs on the shallot is moler caused by Fusarium oxysporum f. sp. cepae (FOCe). This research was conducted to studied the potential of root-colonizing fungi to suppres moler disease on shallot. The researchs were divided into two steps that were laboratory test and screen house test used Completely Randomized Design (CRD). The treatments in screen house test were the combination of four fungi that had best capability to inhibit growth of FOCe. Each treatment was repeated three times. The result showed that root-colonizing fungi could reduce the moler disease but haven’t affect significantly growth component of shallot. Lowest disease intensity was 20% on the combination of AJ01, AJ12, AJ17, AJ18. Root-colonizing fungi have potention to decrease Moler disease.

Abstract

Fusarium wilt (Fusarium oxysporum f.sp. cubense) is an important disease in banana. Fusarium wilt was hard to control because the pathogen can survive in many kind of soils type although there is no host. Therefore, overcoming the disease is urgently needed such as biological control. The endophytic Bacillus of banana was begun to use as antagonist agent to the pathogen. This research aimed to study the mechanism of antagonism and physiological character of Bacillus. There were 27 Bacillus isolates examined in-vitro to test the production of IAA, HCN, chitinase, pectinase, and antagonism. The top ten isolates based on the test in vitro were used to test in planta. The research showed that Bacillus were able to produce IAA, HCN, chitinase, pectinase, and able to retard the growth of Foc colony. The application of isolat B25 on banana seedling could decrease the disease intensity but still unable to prevent the fusarium wilt infection.
