Plants are growing so slowly that the annual Kimberly Weed Research tour will be delayed a week until June 22 as will a similar tour at Aberdeen June 23.
"We've had to delay the tours because it's so cold and wet here that everything's behind," Morishita said.
The University of Idaho Snake River Weed Research Tours will be held at the Kimberly Research and Extension Center at 3806 North 3600 East near Kimberly and the Aberdeen Research and Extension Center at 1693 South 2700 West near Aberdeen.
Registration at both locations will begin at 8 a.m. with the tour starting at 8:30 a.m. A sponsored lunch at noon will conclude the weed tours. Attendees will receive three Idaho State Department of Agriculture pesticide applicator recertification credits at each location.
