May 7, 2012 Agriculture Column


What a cold morning this morning and sounds cooler for the next couple of mornings.  Spring planting is moving along very nicely with a large portion of cereal crops planted.  The big question now is “can I be planting soybeans”.  My question is “do you know when the frost free season is here”.  The time is early and we do have the possible chance of frost later as indicated by the May 20th average frost date for our area.

Monopoly Ends August 1, 2012

According to the latest issue of the Dakota Gold newsletter published by the ND Wheat Commission, the Canadian Wheat Board will lose its monopoly on marketing western wheat and barley crops starting August 1, 2012 with the passage of Federal bill C-18 in late 2011.  This will bring about many changes to both the Canadian and U.S. marketing systems. Canadian producers will now have the opportunity to market their wheat and barley to whomever they choose. Many scenarios have been projected by traders and others in the industry as to how trade flows and prices will be affected. An important point to remember is that total volume of North American wheat will not change, there will still be roughly 1.5 billion bushels of North American spring wheat and durum available to domestic and export markets. With the ability of Canadian producers to sell into U.S. markets and vice versa, companies in both countries are gearing up to buy and sell grain in new ways. Many in the grain trade feel the market will evolve into a “North American” wheat market versus Canadian or U.S.  A lot of questions remain to be answered, but these changes will likely have bigger impact on U.S. HRS and durum producers, and it will change how U.S. and Canadian wheat is positioned and marketed to customers.

Glyphosate Burn-Down Tips

Pre-plant or pre-emergence glyphosate applications to control weeds has become more popular every year.  In large part to the easiness of the product and with the new equipment that makes the application very comfortable and safe.  Following are a few recommendations to get the best weed control from glyphosate applications.

  • Don’t skip on rates.  The cost has been reduced creating a cost effective weed control for you.  Skimping on rates also raises concerns about weeds sneaking by the application and creating the possible start of resistance.
  • With so many different glyphosate products on the market with a wide range of acid equivalent (ae) concentrations make sure that you are applying the correct rate of the product.
  • Consider additional NIS with glyphosate. Some formulations are considered to have a full adjuvant load,             others a partial adjuvant load, while some don’t come with any adjuvants.
  • Cold weather is a stress to plants. Weed control from glyphosate applied during or after cold weather may take longer to see results but should be the same.  Ideal temperatures for applying POST herbicides are between 65 and 85 F.
  • Research data show wide temperature fluctuations (>15 F) 1 to 2 days before and after application are more likely to reduce weed control than consistently cool or cold temperatures.
  • Contact herbicides may antagonize glyphosate resulting in reduced weed control.
