Abstract
The antagonistic fungus, Chaetomium brasiliense was tested to control Phytophthora palmivora causing rot disease of Durian (Durio zibithenus L.) var Montong by crude extracts and Nano-particles derived from Ch. brasiliense. Crude extracts of antagonistic fungus was tested for antifungal biological activities. The crude extracts from antagonistic fungus with hexane, ethyl acetate and methanol were tested against P. palmivora. Crude ethyl acetate from Ch. brasiliense gave significantly against P. palmivora which the ED 50 values was 17.46 µg/ml. Testing Nano-particles were tested for antifungal activities. The results showed nano - particles from Ch. brasiliense gave effectively significantly inhibition of colony growth and spore production which the ED 50 values were 1.08 µg/ml, and 8.68 µg/ml respectively. Application of Nano - particles to control the P. palmivora causing root rot disease of durian in pot experiment was successfully done. The results showed nano-particles from Ch. brasiliense reduced the root rot disease on durain of 40%. The nano-particles from Ch. brasilense gave significiantly high plant growth which were 79.5 cm when compared to the non-trated control.
