Use of Exophytic Microbial on the Control of Fruit Rot Disease of Mango (Lesiodiplodia theobromae)

Post-harvest mango rot is the main cause of yield loss caused by this disease in Bali. Until now, no environmentally friendly control methods have been found such as finding exophyte microbes that are antagonistic to pathogens. The pathogen found to cause fruit rot disease in mangoes is Lesiodiplodia theobromae. Exophytic fungi found in healthy mangoes include: Rhizopus sp. the number of colonies 24 x 102 cfu, while Nucordia sp., A. flavus, and A. niger with colonies 18 x 102 cfu each, and Streptomyces sp. with a colony of 12 x 102 cfu. The highest in vitro microbial inhibitory test results of L. theobromae were obtained from Rhizopus sp. 1 and Rhizopus sp. 4 when 4 hsi and 7 hsi. The results of antagonistic inhibition test on pathogens (L. theobromae) in vivo obtained the highest by the treatment of C (Rhizopus sp. 3) which was very significantly different from K + P (control with pathogens).
