Treatment of grain in Australia

Abstract

Though most of the important insect pests of stored grain occur in Australia, and conditions are ideal for their development, insect control since the introduction of malathion has been so effective that Australian Federal legislation now requires that grain for export must be totally insect-free. The appearance of resistance to malathion in 1968 and its subsequent development in most grain-insect species, however, emphasises the need for alternative safe and effective grain protectants.
