A two-year study investigated the use of chemicallyinduced resistance and biocontrol bacteria for reducing sugarbeet root rot disease caused by the oomycete organ ism Aphanomyces cochlioides. Stand establishment, yield, and quality analysis of sugarbeet from replicated field plots, as well as root rot of seedlings grown in controlled conditions, were analyzed. Bacterial isolates AMMDR1 of Burkholderia cepia and PRA25rifz of Pseudomonas fluorescens were tested for their ability to inhibit reductions in stand and yield caused by A. cochlioides. A commercially available inducer of systemic resistance (harpin protein formulated as Messenger TM ) also was tested in the field for the ability to reduce root rot disease, whereas the inducers harpin, salicylic acid, and riboflavin were tested in growthchamber studies. Field and growth chamber data combined suggested that a subset of the biological treatments in combination with chemical treatments enhanced root yield and recoverable sugar over control treatments even when stand and root rot ratings were unimproved. Integration of induced resistance and biocontrol with cultural practices, chemical treatments, and heritable resistance may lead to
