Control of Cover Crops (05/21/15)

Question: I am wondering if you have done any work on residual control of turnips and radish planted as a cover crop. We had several areas planted last fall and with the dry weather they did not germinate. I am wondering what by best option for residual control in soybeans will be. I am thinking Authority Assist.

 Answer: Turnips and radish are in the Brassica family which is the same family as wild mustard and canola. ALS herbicides are very effective as others listed in the weed guide. Look at ratings for wild mustard in the weed guide.
