NC State Extension Working on Weed Research

 

We’ve been having a conversation with NC State Extension Weed Science Professor Emeritus Dr. Alan York about the weed issues this spring’s weather has brought, as well as stewardship practices with dicamba.  Today, we conclude our visit with Dr. York regarding potentially damaging chemical mixtures:

“Well, yes.  And it’s very obvious that a guy wants to mix things to save a trip across the field.  And he’s already behind because of the weather and two trips just takes twice as long as one.

“Again, when we start mixing materials for thrips in with our herbicides, some of the herbicides, we can get a fair amount of foliar burn.  We can usually go acephate, Orthene with RoundUp generally no issues,   Liberty, generally no issues, it’s when we start mixing Duals and Warrants in with it, and we like to do that because we like the additional residual  control that they can bring.  Well, can, some days can get awfully hot.”

Alan, let’s talk about some of your field work

“Well, we’ve got several things going on this year.  Obviously, a lot of our emphasis is on the new technologies, the ExtendFlex, and the Enlist systems, we’ve been working with them for 10 years, that’s how long it took to get all the approvals to sell them.

“Doing the routine things, do we need pre’s?  if so, which ones?, and what kind of timing do we need?, what kind of tank mixes can we make?  

“And we’re also doing, have done, a good deal of burndown work this year, looking at some problem weeds, looking at some of the new chemistries there, that’s kind of the bulk of it.  A lot of continuing work on pre-emergent herbicides, both from the standpoint of crop tolerance and weed control, particularly Palmer amaranth.  We’ve pretty well decided that we’re going to have to use three herbicides whether we want to or not. We’re just trying to figure out what is the best combination.”

I guess you have these plots all over the state…

“Somewhat scattered, yes.  I’m getting to be an older gentleman, and I don’t like to ride up and down the road like I used to.  They’re congregated more than they used to be, but they’re still scattered out pretty well.”
