Issues with Dicamba Drift

 

When Dicamba became available in most states for use this growing season, it was pretty much a foregone conclusion that somewhere, at some point, there was going to be damage from drift, followed by official complaints, which would result in the herbicide being pulled.  And that has happened in the mid-south.  NC State Extension Weed Science Professor Emeritus Dr. Alan York says we’ve had our problems here, too:

“Well, I think we’re certainly better than what we’re hearing coming out of the mid-south states, that’s not to say we don’t have a few issues around, we do.  But, we think they are, I’m going to say relatively minor, in the big scope of things, now, if it’s your tobacco that got hit, it’s not minor.

“But, over the whole state, we feel it’s a relatively minor issue, although we do have some situations, and we would not be surprised if we see a few more pop up.  Because, double crop beans have been recently sprayed, or will be sprayed soon, we figure we’ve got until the end of July before we’re kind of out of the woods on this issue.”

Missouri and Arkansas have already pulled their labels, as I mentioned earlier, and one temporarily, and how that happens is people making official complaint.

“We’re not encouraging it, for sure.  We think, in the long run, it’s just best for everybody involved if the two parties can get together and come to some kind of gentlemen’s agreement on how we’re going to handle this issue.  The more regulatory complaint there are, the more likely something will have to be done, whether it’s some kind of additional label regulations on the product, or loss of the product.  It’s hard to imagine after what’s gone on in three or four of those mid-south states that it’s not going to be a topic of discussion that EPA is going to have to pull the registration and we certainly don’t want to see that happen. 

“We certainly don’t want to see that happen.  Yeah, we’ve got a product that’s got some baggage in it, but at the same time, I think most people have been happy with the performance this year.  It’s certainly another tool, we should have the good sense to know that we can’t use that tool everywhere.  But, where we can use it, it’s been a good tool, and as we’ve talked for the last 15 years about all the issues with resistance, we’re not seeing new mechanisms of action, but we continue to lose others to resistance, we’re flat running out of tools, and we’d like to keep that one if we can.”

On Monday, we’ll recap some application recommendations with Dr. Alan York, NC State Extension Weed Science Professor Emeritus.
