In Washington, potato late blight has spread to four fields in block 1, just north of the Tri-Cities. Washington State University plant pathologist Dennis Johnson provided the latest control recommendations on the Late Blight Hotline.
Johnson;“In this area fungicide applications should be applied every seven days. Through out the Columbia Basin fungicide applications should also be applied every seven days through July.”
Johnson says keeping the application interval short is essential in managing late blight.
