A Comparison of Maize Stalk Rot Occurrence in Bt and Non-Bt Hybrids [PDF]
Plant Disease, 2002 Stalk rots, caused by a complex of fungal species, are among the most widespread and destructive diseases of maize. Larvae of the European corn borer (ECB) (Ostrinia nubilalis) promote stalk rot development by creating entry points for fungi, serving as vectors of pathogens, and causing physiological stress that may predispose plants to stalk decay ...

Lower mycotoxin levels in Bt maize grain [PDF]
Agronomy for Sustainable Development, 2010 Mycotoxins produced by Fusarium spp. during plant cultivation induce severe diseases in animal and humans. In 2007 a European Union regulation set maximum concentrations of mycotoxins in maize and derivatives of 4000 ppb for fumonisins B1 and B2, 1750 ppb for deoxynivalenol, and 350 ppb for zearalenone.

Linking land use patterns and pest outbreaks in Bt maize [PDF]
Ecological Applications, 2021 AbstractWestern corn rootworm, Diabrotica virgifera virgifera LeConte (Coleoptera: Chrysomelidae), is a major pest of maize in the United States and is an invasive pest in Europe. Maize is the only agricultural crop on which western corn rootworm larvae can survive and this insect requires two consecutive years of maize cultivation to complete its life

Abundance of non-target pests in transgenic Bt-maize: A farm scale study
European Journal of Entomology, 2005 The impact of transgenic Bt-maize, expressing the Cry1Ab protein, on aphids, leafhoppers, cutworms and wireworms was evaluated at the farm scale by comparing their abundance on Bt-plots and those sown with the isogenic variety over three consecutive ...
