Degree Day Information for Iowa

It's summer...Brrr!

Summer dawned in Iowa with a shiver. For just the week of June 21, we fell behind 2 to 4 days worth of normal heat accumulation. Not all was bad though, because the rains largely abated, allowing producers to catch up on post weed spraying in most areas. That said, there are some problems with weeds that have gotten too large for easy control that will remain for a while. Field crop specialists report that soybean aphids are few and far between so far, but scouting should continue as weather conditions change and the season progresses.
