Assessment of effect of anthracnose infection on the yield of mango: Two mango tree branches randomly selected at the upper canopy were sprayed with spore suspension of Colletotrichum gloeosporioides using hand sprayer. Another one was sprayed with sterile distilled water as a control following Okigbo and Osuinde (2003) method slightly modified. All branches were then covered with sterile polyethylene bags for 24 h. After 24 h, one branch out of the two inoculated with Colletotrichum gloeosporioides spore suspension was treated with Ferbam (Ferric dimethyldithiocarbamate) at 4.3 kg ha-1 applied as a dilute spray at 400 L ha-1 and thereafter maintained at fourteen days intervals until three weeks to harvesting while the other was left untreated. The experiments consisted of 5 trees with each tree representing a replicate. Fruits retained at harvest were counted and anthracnose infection was assessed as a product of the difference in number of fruits retained in treatment from control using the following formula:
