Ears may be kept in outdoor cribs. Maize may also be shelled and stored indoors in sacks or other containers. Dehusk and shell well dried grains before storage. The moisture level in maize must remain below 11% if the maize is to be stored for long periods (more than 3 months), otherwise aflatoxin may develop, producing toxic side effects for consumers of the grain. Remove all rotten cobs from the produce before shelling. After shelling, remove all debris, insects and store cleaned grains in jute bags. Pack bagged maize on a pallet away from the floor in a well-ventilated room. For longer storage periods protect grains against storage pests by using insecticides.
Common storage insecticides are Actellic 25 E.C. and Aluminum phosphide (e.g. Phostoxin and Gastoxin). For every 100 kg bag of maize, mix 4 ml of Actellic 25 E.C. with 170 ml of clean water and spray the solution on to the shelled grain before it is bagged. To store with Aluminum phosphide, line the bad with polythene bag. Fill the sack half full and place one tablet of either Phostoxin or Gastoxin wrapped in a paper/cotton wool. Fill the sack completely and add another tablet and sew the tip of the sack properly to prevent the escape of the chemical which works in the gaseous form. Therefore, whenever Aluminum phosphide tablets are used, ensure the store or container is airtight to avoid the escape of fumes because they are extremely poisonous to human beings when inhaled. Do not keep grains treated with phostoxin in living room. Treat walls and floor of rooms with chemicals and keep the doors locked until grains are needed.
