Iowa State University Extension climatologist Elwynn Taylor, integrated pest management specialist Rich Pope, and soybean agronomist Palle Pedersen are the Aug. 24 weekly crop and weather report guests.
Taylor says the ocean's temperature is reported to be the warmest since 1909 and that could lead to an increase in tropical storms. These are storms that could impact Midwest weather patterns.
Pope repeats his recent message - late season crop diseases are being reported and scouting is still recommended.
Pedersen says soybean aphids are very spotting; they are beyond threshold in several Iowa counties and spraying is underway. Big question is when to stop spraying for aphids. This is a perfect year to check varieties for sudden death syndrome and determine varieties for future years.
