The effect of a winter cover crop, Downy Brome, on damage to corn roots caused by larval western corn rootworm feeding was studied during the growing seasons of 2005, 2006, and 2007. The experiment consisted of two trials; each with 32 plots measuring 15 meters wide by 18.3 meters long. Each trial was run for three years in continuous corn. Sampling was done on the second and third years. Treatments consisted of high or low Brome levels created with herbicide treatments. In each plot six plants were rated for rootworm feeding using the Iowa State 1-3 damage scale. In the South trial there was no significant difference in damage levels between the high and low cover treatments in either year. This appeared to be due to the lower Brome stand in this trial. In the North trial there was a significant difference both in 2006 and 2007 with high Brome treatments having higher feeding damage ratings than low treatments. Residue measurements showed that high Downy Brome treatments contained more residue than low treatments. This data suggests that cover crops may be associated with higher rootworm damage.
