A predictive model for ergot ascospores was developed for the Lower Columbia Basin of Oregon that uses accumulated degree-days (beginning January 1, with a base temperature of 50\u00b0F and upper threshold temperature of 77\u00b0F) to forecast when ascospores are likely to be present.<\/p>\n\n\n\n
According to the model, most ascospores are produced in the Lower Columbia Basin when accumulated degree-days are between 414 and 727. Based on this model, the degree-day threshold was reached on May 27, 2022 in Hermiston, OR<\/strong> (accumulated degree days = 422).<\/strong><\/p>\n\n\n\n At this time in 2021, accumulated degree-days were 646.<\/p>\n","protected":false},"excerpt":{"rendered":" A predictive model for ergot ascospores was developed for the Lower Columbia Basin of Oregon that uses accumulated degree-days (beginning January 1, with a base temperature of 50\u00b0F and upper threshold temperature of 77\u00b0F) to forecast when ascospores are likely to be present.
