Descripción
Technology is available to eliminate all types of insect infestation from maize and other food-aid commodities and at all stages of transit from producer to consumer. There are however, situations where complete elimination of insects is not justified either on economic or environmental grounds. Control of insects is dependent on application of the appropriate technique under suitable conditions. For effective disinfestation using fumigants the two most important factors are provision of a gas-t ight enclosure and good distribution of gas throughout the commodity. It is essential that contracts for the supply of infestible food-aid commodities indicate clearly the control measures that should be used and the conditions under which they must be applied.
