Two informative videos have recently been posted.
The first is Diagnosing Soybean Injury Caused by Dicamba, a PMN “Focus on Soybean” webcast by Dr. Bill Johnson, Professor of Weed Science at Purdue University. In his presentation, Dr. Johnson provides the following:
• Images of non-Xtend soybeans that were exposed to dicamba;
• A summary of the causes of auxin herbicide injury to non-tolerant soybean;
• Details about how developmental stage of sensitive soybean exposed to dicamba may affect yield response differently; i.e., exposure during reproductive development is likely to result in more yield loss than exposure during early vegetative development;
• Evidence that early-season injury ratings of sensitive soybean varieties following exposure to dicamba are not a reliable predictor of yield loss;
• How yield reduction from dicamba injury to sensitive varieties is associated with height reduction and killing of the terminal bud; and
• Evidence that soybean that is not tolerant of auxin herbicides is more injured by exposure to dicamba than by exposure to 2,4-D.
The second is a presentation by Dr. Keith Coble, MSU Ag. Econ. Dept. Head, titled “Tariff and Trade Wars: Potential Effects on Mississippi Agriculture” made at the 2018 Row Crops Short Course. In his presentation, Dr. Coble:
• Presents the reasons for the trade war with China (not about agriculture);
• Defines a tariff as a tax on imports;
• Shows how much of US major agricultural commodities are exported (soybeans at 50%);
• Shows that China has been the major buyer of US soybeans;
• Presents evidence that the tariff war is resulting in huge increases in US soybean ending stocks;
• Shows how the tariff war is affecting the projected estimate of US crop value and its negative effect on net farm income;
• Indicates that the tariff war has not affected the amount of soybeans in the world, but rather has changed the trade flow or where soybean exports are going;
• Shows that alternate trade flows of US soybeans will not offset trade with China; and
• Shows that new farm income estimates are down by about 50% since 2013, and the trade war with China will only exacerbate that.
Overall, the net effect of the trade war with China will drastically alter both the present and future prospects of US agriculture, and will especially be a drag on soybean prices and net income realized from soybean production.
I encourage soybean producers to view both of these videos. They provide unique information pertaining to their contained subjects.
