SCN Resistant Soybeans are Showing Some Problems

 

Nematologist Greg Tylka  with Iowa State University says soybeans with Soybean Cyst Nematode resistance are becoming less effective. He calls it an alarming trend that sets the stage for even more yield loss to SCN in the future. Just about all the SCN-resistant varieties have the same resistance gene, and Iowa State researchers analyzed 25 years of data from four-row variety evaluation research plots to look for long term trends. The results show a breakdown in resistance in SCN-resistant soybeans. Tylka says the buildup in SCN resistance is similar to weeds developing resistance to glyphosate after prolonged use of a single mode of action. The study concludes that resistance issues will worsen if farmers only have the same resistance gene going forward.

Exports Slip on NAFTA Uncertainty

A panel of expert witnesses told the House Agriculture Committee last week that speed is a critical factor in renegotiating the North American Free Trade Agreement. The uncertainty over how negotiations may play out is causing some importers to look elsewhere for suppliers. Many of the importers that are looking elsewhere for chicken and grain products are located in Mexico. Those buyers are looking at South America to supply their needs and it shows in America’s export numbers. Corn, sorghum, and barley exports are down seven percent and will only get worse if negotiations drag on for a long period of time.

EPA Formally Proposes WOTUS Withdrawal

The Environmental Protection Agency and the U.S. Army Corps of Engineers will formally propose to withdraw the “Waters of the U.S. Rule,” a controversial Obama-era rule on clean water. This move will mark the end of years of efforts by farm groups to get rid of something they called a burdensome federal overreach.

That formal step kicks off a 30-day public comment period. Critics of the withdrawal have called for more time to weigh in on the matter. The proposed rule to withdraw WOTUS won’t have much of a noticeable effect out in the countryside.
