A 2014 multi-site field study on the effects of Clariva seed treatment on soybean yield and Soybean Cyst Nematode reproduction

Bruce Potter, Senyu Chen, Phil Glogoza and Ryan Miller

The soybean cyst nematode (SCN) is a serious pest of Minnesota soybean and has been managed with crop rotation and soybean varieties with resistance to SCN. SCN populations virulent on (able to infest, reproduce on and damage) SCN resistant soybeans are increasingly widespread. Virulence on the PI 88788 resistance source is the most common, but increasing numbers of field populations virulent on Peking or both PI88788 and Peking resistance sources have been observed (Chen, et al. 2011). Therefore, effective chemical or biological complements to resistant varieties would be helpful to soybean growers’ SCN management programs.

USDA Cover crop guidelines updated

Jill Sackett and Dr. M. Scott Wells, University of Minnesota

The United States Department of Agriculture (USDA) has released updated termination and insurance guidelines for farmers using cover crops. An interagency workgroup organized by Farm Service Agency (FSA), the Natural Resources Conservation Service (NRCS), and Risk Management Agency (RMA) developed a cover crop management guide in order to have consistent and flexible cover crop policy for the Nation’s farmers. The third version of the guide, NRCS Cover Crops Termination Guidelines, was released in September 2014. RMA also has released updated insurance information on its 2015 Cover Crop FAQ website.
