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.

The Iowa Grain Quality Initiative (IGQI) is a cutting edge grain quality research and information program. The interdisciplinary project performs the "rapid response function" at ISU for the grain industry. Through diverse expertise of affiliated faculty and the use of information technology, the project has addressed grain production and processing topics quickly, giving producers and agribusinesses the information needed to make business decisions. Challenges related to genetically modified grains have accelerated the use of alternative delivery systems.
The goal of the Pesticide Safety Education Program (PSEP) is to provide educational information throughout Iowa on the safe and effective use of pesticides. PSEP is responsible for Pesticide Applicator Continuing Instructional Courses (CIC’s) in cooperation with the Iowa Department of Agriculture and Land Stewardship (IDALS). Other programs that PSEP is involved in include integrated pest management, worker protection, environmental quality, and agricultural health.
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.
The International Survey of Herbicide-Resistant Weeds monitors the evolution of herbicide-resistant weeds throughout the world. The site is a global collaboration between weed scientists with a common goal of understanding, preventing and managing the occurrence of herbicide-resistant weeds.
