But farmers and the ag industry can manage the biggest risks, he told delegates at the International Rapeseed Conference in Saskatoon this past summer. Dr. Udo Heimbach researches pesticide use and environmental effects with Germany’s Julius Kuhn-Institut. He presented research studying neonics’ effects on […] Read more
