Abstract ‘Special Hibush’ eggplant were transplanted to a Sassafras sandy loam field on May 20. Micrgplots consisted of screen cages 20 inches x 15 inches x 14 inches arranged with 2 plants/cage. Beauvariabassiana (WP, 80 x 108 spores/gm) and Metarhiziumanisopiiae (formulated on rice, spore concentration unknown) were formulated and supplied by BioControl International. Methods of application with B. bassiana were soil surface spray (1.5 g/100 ml), soil mix (1.5 g/100 ml/kg soil), foliar spray (25 g/500 ml with spreader sticker) and dilute foliar spray (same as foliar spray diluted 1:10); methods of application with M. anisopliae were soil mix broadcast (40 gm/kg soil) and soil broadcast (40 gm/2,000 sq. cm). All sprays were applied with a CO2-operated bicycle sprayer with 3 nozles/row calibrated to deliver 45 gal/acre at 40 psi. Twenty adult Colorado potato beetles were buried 2 inches below the soil surface in the center of the microplot and covered with soil just prior to treatment application (May 27); cages were than placed over each microplot. Experimental design was a randomized complete block with 2 replications.
