NOTES REGARDING THE 2002 CEREAL TRIALS (posted by John Burns, 9/27/02)

 

Listed below are notes taken at different locations for the 2002 WSU Extension Uniform Cereal Variety Testing Trials.  The notes are intended to highlight significant field conditions that contributed to yields at each of the locations.  In summary, the most pronounced effect on yields for both winter and spring cereals was the influence the 7-11 May 2002 spring freeze followed by an additional freeze in some areas in the early part of June 2002 followed by a 2-week heat spell in the middle of June 2002.  The spring cold spell was most pronounced at the Connell, WA location where plants were nearly completely killed.  Winter wheat was in the boot stage of growth, flag leaf beginning to emerge at the time of the cold period.  A new race of Stripe rust appeared in mid-June 2002 and had a significant effect on the majority of spring wheat varieties.  Stripe rust appeared on susceptible varieties of winter wheat but not to a great extent.  Barley did not show any Stripe rust symptoms. Hessian fly infestations were severe in spring wheat at the Dayton, WA location.  The infestations appeared early and Hessian fly larvae attacked plants at the crown causing considerable damage in susceptible varieties.
