Spud Scoop July 31, 2020
Welcome to this week’s Spud Scoop. Late blight severity values continue to rise, but no late blight has been reported and no DNA was found in spore traps this week. Aphid numbers are down from last week but are more widely distributed. The warm temperatures are causing tuber sets to be lower and as a result, tubers are sizing rapidly. As an example, a tuber from an early planted research trial was nearly 24 ounces. Heat stress is also causing cracking and secondary growth. In general, the crop is progressing well, and harvest is getting into full swing for fresh growers in central Minnesota. Have a spudtacular week!
