Late Infections of NCLB and GLS Should Not Limit Yields

Published on Wednesday, August 31, 2016

The 2016 crop continues to progress toward maturity with above average growing degree days and is pointing to an early corn harvest. Since last month’s issue, high temperatures during the weeks surrounding pollination alternated from well below to well above normal. The varying temperature periods served to prevent both northern corn leaf blight (NCLB) and gray leaf spot (GLS) from enjoying favorable conditions for extended periods.

While both NCLB and GLS are present today, the few late infections will not significantly reduce yields. Soybean disease pressure has also been below normal for 2016 with little change expected through grain fill. Other soybean threats which increased in areas this year included herbicide resistant waterhemp, Japanese beetles, spider mites, and even soybean aphids. Insects will remain a threat to soybeans into maturity, so scouting is a must to properly manage them. Stay vigilant to the end this year.
