Palmer amaranth has been identified both in crop fields and in conservation plantings using native seed mixes. Early detection is essential in order to prevent the new weed from getting permanently established in fields where it has been introduced. This publication will help people new to Palmer amaranth differentiate it from waterhemp and the other weedy pigweeds found in Iowa.
Bacterial leaf streak, caused by Xanthomonas vasicola pv. Vasculorum, was recently identified in Iowa. The disease has been found in field corn, seed corn, popcorn and sweet corn. Based on what we know about other bacterial diseases, the pathogen that causes bacterial leaf streak likely survives in corn residue and is spread by wind and rain/irrigation. The impacts on corn yield production are yet to be determined.

Choosing soybean maturities and when to plant soybeans are two critical decisions that farmers make each year. Typically, soybean variety selection occurs months before soybean planting occurs. An added complexity in the decision making is the weather conditions at the time of planting. Each year farmers are faced with the decision of planting into marginal conditions or the potential of late planting. Also, spring and early season weather sometimes forces farmers to replant soybeans later than ideal planting windows.
