Fusarium ear rot severity (top) and fumonisin B1 concentrations in kernels of Bt and conventional corn hybrids.

Figure 1. Fusarium ear rot severity (top) and fumonisin B₁ concentrations in kernels of Bt and conventional corn hybrids in a field experiment conducted in Boone Co., IA, in 1997. Asterisks indicate significant differences within Bt and conventional hybrid pairs ( alpha = 0.05). Natural ECB infestation - endemic insect populations only; Manual ECB infestation - 50 neonatal European corn borer larvae were placed on each plant at the whorl stage and silking stage.
