Palmer Amaranth Work Making a Difference
A Muscatine County farmer’s determination to eradicate a relatively new yield-robbing weed in Iowa is inspiring others to do the same.

Roger Hargrafen discovered Palmer Amaranth — a tough herbicide resistant weed native to the southwest United States capable of decimating row crops — in a 5-acre section of a soybean field last September. Since then, he’s diligently worked to get rid of the weed and helped spread the word why that’s important and how to do it.

ISU weed and agronomy experts believe Hargrafen’s actions are making a difference. Steps taken include not harvesting the affected area, planting cover crops, intensive management such as scouting and hand weeding, participating in a herbicide trial and using herbicides with effective, multiple modes of action, thoroughly cleaning equipment and more.

Save on time, money, and pesticides by following economic thresholds and taking advantage of biological controls is the idea behind applied research conducted through a North Central Soybean and Research Program (NCSRP) grant led by Kelley Tilmon, Associate Professor and Soybean Extension Entomologist at South Dakota State University.
 
The key findings and recommendations from this NCSRP project are now available through three easy-to-follow, open-access webcasts produced by the Plant Management Network (PMN), a nonprofit publisher of crop management information:

Managing White Mold in Soybeans in the Great Lakes Region
Wed, July 2, 2014
Farmers in the Great Lakes region may be concerned about white mold in soybeans in 2014 and how to properly manage this disease.

By Martin Chilvers, Michigan State University Extension, Department of Plant, Soil and Microbial Sciences; Kiersten Wise, Purdue University; Damon Smith, University of Wisconsin; Carl Bradley, University of Illinois; and Daren Mueller, Iowa State University

White mold, also called Sclerotinia stem rot, is a disease caused by the fungus Sclerotinia sclerotiorum. It is not common every year in in the Great Lakes region, but farmers that have battled the disease in the past will want to assess the risk of white mold development as soybeans approach flowering, or growth stage R1 – plants have at least one open flower at any node.
