Time to start scouting for corn stalk rotIntegrated Crop Management News
AbstractIn the late part of the growing season, it is time to pay attention to stalk quality. Some fields will be at high risk for stalk rot this year due to drought stress or wind damage that has already occurred. Watching these fields closely could prevent further losses due to lodging. Scouting should be done before black layer, approximately 40-50 days after pollination. While scouting for stalk rot, look for visible symptoms (such as stalk lesions) and test stalk firmness by pinching the lower internodes with thumb and forefinger. Healthy stalks are firm and cannot be compressed.
