“…One of the pathogens is the fungus Colletotrichum gloeosporioides, which causes anthracnose in banana plants (Abd-Elsalam et al 2010;Gautam 2014a;Gautam 2014b). Anthracnose attacks on various plant organs often start with the appearance of minute black or dark brown spots, which then grow and consolidate to cause damage to these organs (Bele et al 2018). The pathogenic fungi can infect plants in the field and become inactive; after the banana fruit is harvested, C. gloeosporioides begin to grow again as the ripen banana fruit and cause damage.…”

Abstract. Pangastuti A, Pratiwi H, Setyaningsih R. 2023. Screening for endophytic bacteria from Ambon Banana (Musa paradisiaca L.) as biocontrol agent of anthracnose (Colletotrichum gloeosporioides) on bananas fruit. Nusantara Bioscience 15: 238-244. Post-harvest Ambon Bananas (Musa paradisiaca L.) are sensitive to anthracnose disease, caused by Colletotrichum gloeosporioides, and causes the fruit to rot quickly. Thus, chemical fungicides are employed, damaging living organisms and the environment. One solution is biocontrol using endophytic microorganisms as antagonistic agents against the anthracnose fungus that causes anthracnose disease. This study aimed to obtain potential endophytic bacteria from the Ambon Banana plant that had inhibitory activity against the growth of the pathogenic fungus C. gloeosporioides that causes anthracnose in bananas. Endophytic bacteria were recovered from Ambon Banana roots by crushing plant components. Therefore, bacterial isolates were tested for antagonistic interactions with pathogenic fungi using the dual culture approach. The 16S rRNA gene sequence analysis was used to identify bacterial isolates with the most significant inhibitory potential. According to the findings of this study, seven isolates of endophytic bacteria, A2-1, A2-2, A5-2, A6-2, A6-3, A8-1, and A9-1, can limit the growth of the pathogenic fungus C. gloeosporioides. The strain A6-3, identified as Pseudomonas pseudoalcaligenes, exhibited the greatest potential as a biocontrol agent against the pathogenic fungus C. gloeosporioides. It achieved the highest inhibition rate of 43.59%, resulting in an extended fruit shelf life and reduced harm susceptibility.

The cocoa crop is part of the peasant’s economic activity and agroforestry systems in many regions of Colombia and the world. Its yields are diminished by phytosanitary problems, being the frosty pod rot caused by the fungus Moniliophthora roreri, the most limiting disease with decreases in production of over 90%. In this study, samples of cocoa leachates from commercial producing farms were characterized and the antifungal activity of sterilized, non-sterilized, and filtered cocoa leachates against M. roreri was evaluated under in vitro conditions, at concentrations of 1, 2, 5, 10, and 15%. Monosporic isolates of the pathogen were obtained from diseased fruits collected from cocoa-producing farms in the municipality of Yacopi in Cundinamarca, Colombia. The effect of leachates on M. roreri conidial germination, mycelial growth, and inoculum production was evaluated. It was found that non-sterilized cocoa leachates at all concentrations caused 100% reduction on the three variables evaluated, while sterilized leachates generated the same effect at concentrations of 10 and 15%. Filtered leachates showed no inhibitory effect on the radial growth of the pathogen, but they caused a reduction of conidial germination of 89.9, 90.5 and 95.9% at concentrations of 5, 10, and 15%. The presence of malic, citric, and ascorbic acids, compounds such as NH4, PO4, and NO3, and elements such as Ca, K, Na, Mg, and Cl in the evaluated leachates was identified using high-efficiency liquid chromatography and physicochemical analysis. This research showed the potential of cocoa leachates, even at low concentrations, for the control of M. roreri, which can be attributed to the action of specific compounds such as those found in chromatographic tests.
