Digging into Research
Wheat stem sawfly larval mortality did not occur between fall and spring sampling periods indicating that populations are not affected by abiotic or biotic factors during the winter. The populations of wheat stem sawfly and its natural enemies varied across fields in southern Alberta. The...
AC Ultima formed relatively solid stems at lower internodes compared to Pronghorn, although this did not reduce stem cutting by wheat stem sawfly. Higher seeding rates of both cultivars resulted in lower wheat stem sawfly damage and higher amounts of sawfly parasitism. Little research has been...
Seed solid-stemmed CWRS and CNHR wheat varieties at 30 to 35 seeds per square foot to maximize stem solidness and reduce the impact of wheat stem sawfly. For hollow-stemmed CWRS varieties and durum wheat, seed at 40 to 45 seeds per square foot. Growing solid-stemmed wheat...
Seed at least 40 seeds per square foot (400 seeds per metre square) for optimum yield and wheat stem sawfly management when growing solid- or hollow-stemmed durum wheat varieties. The foundation for reducing yield loss from wheat stem sawfly (Cephus cinctus) in wheat varieties is growing...
