Degradation of grain quality during storage is mainly caused by insects and microorganisms. To protect against insects, prevailing practices usually require the application of pesticides and fumigants directly to the stored grain; long-term storage can involve repeated applications. Direct application results in accumulation of chemical residues on the grain, especially from pesticides. A simple delivery system, in which the pesticide (chlorpyrifosmethyl) is incorporated in a biopolymer (xanthan gum), has been formulated with the objective of reducing these residues while increasing the period of effectiveness of a single application. The biopolymer-based formulation was compared to a conventional formulation on the basis of bioassay tests and residue analysis. The biopolymer-pesticide formulation was effective over a longer period of time and produced significantly smaller residues than the conventional emulsifiable concentrate formulation.
