Three concentration levels of maize cob powder 5 g, 50 g and 80 g per 500 g of the local maize variety were compared with the control experiment containing 5 g manufacturer's recommended phostoxin chemical. Findings showed that the use of phostoxin chemical was significantly more effective than use of 5 g and 50 g levels of maize cob powder. However, ash powder concentration of 80 g (per 500 g of maize grains) may effectively control weevils in stored maize grain and thus, can adequately serve as a safer and cheaper alternative to use of conventional chemicals in weevil control.
