The goal of this page is to help potato growers in the Columbia Basin of Washington make informed decisions about late blight management. Here we present forecasts and recommendations. The forecasts are derived from models developed by Johnson et al. 1998, Johnson et al. 2009 & Johnson and Cummings 2016. Each week, we will post probabilities of annual late blight outbreaks along with recommendations for Othello, Prosser and Tri-Cities.
