EnglishA sprayable liquid biodegradable formulation comprising biocontrol microorganisms imbedded in a dispersed starchbased bioplastic is effective for delivering biocontrol microorganisms and bioactive compounds to soil, crops and seeds and facilitating positioning of biocontrol agents in close proximity to target pests. After application with conventional spray equipment, water evaporates rapidly and the dispersed bioplastic formula remains, serving as a prolonged growth substrate for the biocontrol microorganisms. Application of the bioplastic dispersion formulation comprising Beauveria bassiana significantly reduced damages caused by the European Corn Borer in corn and the Tarnished Plant Bug in cotton. Applying a formulation of spores of a non-aflatoxigenic A. flavus isolate resulted in a 97% reduction of aflatoxin contamination of corn. The bioplastic dispersion formulation is effective in delivering crystal Bacillus thuringiens endotoxins to European Corn Borer larvae, causing 72% mortality. The sprayable bioplastic formulation protects seeds from soil-borne pathogens, thereby reducing damping-off in tomato plants by up to 85%.
