Abstract

Black banded disease of mango (Mangifera indica L.) caused by Peziotrichum corticolum (Massee) Subramanian, has become increasingly problematic in recent years, inflicting damage on midribs, twigs, branches, and veins of leaves. This study clearly confirmed the identification of the causative agent as Peziotrichum corticolum. The investigation delved into the diverse cultural and morphological characteristics of P. corticolum across six distinct media at a consistent room temperature of 27±1ºC, including Potato dextrose agar, Nutrient agar, Czapek’s agar, Oatmeal agar, Host extract dextrose agar, and PDA + sugar. Notably, Potato dextrose agar, Oatmeal agar, PDA + sugar, and Czapek’s agar emerged as the most supportive media for maximal mycelial growth of P. corticolum on the 12th day post-incubation, while Host extract dextrose agar exhibited the least radial growth. Cultures of P. corticolum showcased significant diversity in cultural characteristics such as the type of growth, mycelial color, pigmentation, and colony margin.

Conclusion

In conclusion, this study definitively identifies Peziotrichum corticolum as the causative agent of black banded disease in mango trees. Through a thorough investigation of cultural and morphological characteristics on various media, it was determined that Potato dextrose agar, Oatmeal agar, PDA + sugar, and Czapek’s agar are the most conducive for maximal mycelial growth of P. corticolum. The study highlights significant diversity in cultural traits among different media, including variations in growth type, mycelial color, pigmentation, and colony margin. These findings contribute valuable insights into the biology and optimal growth conditions of P. corticolum, providing a foundation for further research and potential management strategies for mitigating the impact of black banded disease on mango crops.
