Growers Prefer Integrated Approach to Extend Life of CRW Traits

Poll Shows Growers Choose Combination of BMPs, Which Can Extend Trait Life by up to 50% (Audio Files)

Lead-In: In many geographies, conditions such as mild winters and low moisture are making it likely that growers should expect the recent rise in corn rootworm (CRW) pressure to continue into next season. For those with affected or at-risk fields, it could mean plants with damaged root systems, poor seed set and yield loss. A critical component of any management plan is using defensive CRW trait technology, and according to a recent poll of U.S. corn growers by Pioneer, most growers prefer partnering traits with a combination of best management practices (BMPs) such as crop rotation and scouting to help maximize and prolong efficacy. Pioneer Agronomy Manager Matt Essick reviewed more than 900 responses and adds his advice for dealing with this challenging pest. (:30)
