Endophytic Colonization and Plant Growth Promoting Effect by Entomopathogenic fungus, Beauveria bassiana to Red Chili (Capsicum annuum L.) with Different Inoculation Methods

Abstract

Beauveria bassiana (Bals.) Vuill is one of entomopathogenic fungus, that be able to endophytically colonize different plants. Beauveria bassiana can promote the growth of red chili following their endophytic establishment within plants through seed treatment, soil drenching and foliar spraying. The aims of this study were: (i) To get the best colonisation B. bassiana from different isolates and to differentiate inoculation methods, i.e. seed immersion, soil drenching and foliar spraying, for the endophytic inoculation of B. bassiana in red chili; and (ii) to assess the effect of B.bassiana to stimulate or trigger plant growth from isolate Wheat, Coffea, Cacao and Leptocorisa acuta. Our result showed that all of B. bassiana isolate were able to colonize seedling of chili and B.bassiana of wheat isolate was the best isolate giving spuring seedling or plant growth. From the three inoculation methodes, inoculation B. bassiana by foliar spraying was the highest colonisation. The highest colonization was in leaves, and the second were in stem. Root plant was the poorly colonized by B. bassiana fungus.
