Spud Scoop July 17, 2020
Welcome to this week’s Spud Scoop. The Potato crop is progressing well with some challenges from the weather. Hot temperatures are initiating heat sprouts to form, producing rapid development of Colorado Potato Beetles and encouraging thunderstorms. Excessive rainfall in the Red River Valley is likely causing iron deficiency chlorosis (IDC) of some potato varieties. This is similar to the IDC often observed in soybean. With soils drying down I have observed plants growing out the IDC with new green leaves forming.
