Prashant Jha

Prashant Jha is an Associate Professor and Extension Weed Specialist with the Department of Agronomy at ISU. His research program is focused on improved understanding of weed biology and ecology to develop effective, integrated weed management strategies in corn and soybean production systems of Iowa and Midwest, optimization and stewardship of herbicide application technology and herbicide use, and understanding the evolution of herbicide resistance including genetic/molecular and physiological mechanisms, and other factors influencing weed population dynamics and management in agroecosystems. This includes emphasis on late-season weed seed bank management and reducing weed seed inputs at harvest. His research interest also includes UAV and ground-based hyperspectral imaging and machine learning of weed species in-crop for developing weed maps and for early detection of herbicide-resistant weed biotypes in the field. His statewide extension and outreach program is focused on current and emerging weed problems in Iowa and providing research-based information to growers on cost-effective, multi-tactic approaches for prevention and mitigation of herbicide-resistant weeds in agronomic crop production systems. He serves as the herbicide evaluation and demonstration program leader, with the ultimate aim to develop cost-effective and sustainable weed control recommendations for corn and soybean producers in Iowa. His programming supports extension, agribusiness, governmental agency programs, and other educational needs throughout Iowa.

The spread of multiple-resistant weeds threatens Iowa’s production system. In order to slow the expansion of resistance, greater diversity in weed management is necessary.  An October 21 workshop will discuss one potential alternative weed management tool that is used in other parts of the world...
