ABSTRACT
This study followed the rising occurrence of Bombax ceiba leaf spot disease across forests alongside gardens and plantations because the disease seriously endangers tree health. The existing control measures proved ineffective while Bombax ceiba leaf spot disease exclusively impacts farmers who use these trees to support their livelihoods. The Bangladesh Forest Research Institute (BFRI) performed a field study to confirm the leaf spot disease causative agent and assess copper fungicide effectiveness in disease control. The research found that Colletotrichum gloeosporioides functions as the main cause of the disease. This research evaluated disease severity through studies of pH levels, temperatures (T), humidity (H) and together with media effects. The pathogen showed its highest growth rate on potato dextrose agar (PDA), pH 7, 15℃ temperatures and 90% humidity requirements. Carbendazim provided the most effective treatment by completely eliminating fungal spores from the environment thus minimizing disease occurrences. This study showed Trichoderma spp. worked successfully as a biological control agent which proved highly effective at lowering disease intensity while providing environmentally responsible methods for disease control.
