摘要：
Field studies were conducted at Hoytville and Wooster, Ohio, USA from 2006 to 2008 to determine the influence of three planting dates and transgenic Bt maize on incidence and severity of ear rots following European corn borer infestation Significant linear correlations were obtained between European corn borer ear damage and Gibberella ear rot The use of Bt maize reduced incidence and severity of ear rot compared to non-Bt hybrids Compared with short season hybrids, significant reduction in ear rots occurred on full season hybrids The benefit of using Bt hybrids to control ear rot was more evident as planting was delayed than early planting
