Soybean Traits and Weed Control Options (From Ag PhD Show #1099 – Air Date 4-28-19)


D: I am so excited about
soybeans, because we have so many different traits now to
choose from to help us with our weed control. We’ll
discuss the traits that are on the market right now and
which ones may be more beneficial for you. B:
Alright let me first start with the old traits. Roundup
Ready 2 – love it, yield is great, we can spray Roundup. The problem is-Roundup isn’t
killing a lot of the weeds that are out there right now
– the broadleaf weeds. Ok, so then you look at Liberty. There are no resistant weeds
to Liberty, but the problem is, the straight Liberty
trait – they haven’t really been breeding new genetics
into that. So in my eyes, I’m not planting Roundup 2
anymore, I’m not planting straight Liberty anymore. The two traits I’m really
looking at is Xtend and Enlist. D: Let’s talk about
Xtend as this one’s been out now for a few years. You’ve
got the options of spraying Roundup or spraying dicamba. Dicamba has been very
misunderstood around the country. It’s a product
we’ve been using, really my whole lifetime, and it is
pretty effective on most broadleaf weeds, but it’s
not bulletproof. You can’t just say, “Well I’m going to
spray at any time of the day”, you’ve got some
restrictions on that now, and you have to look those
up before you apply – in fact, you have to look them
up within a week of when you’re going to apply just
to be sure things haven’t changed and more options
aren’t out there for you. B: Let’s just put it this way,
you’ve got to spray in the daylight hours and finish up
your spraying at least a couple hours before sunset. Our big concern here with
the dicamba is really the off-target movement,
especially with volatility. So what we really prefer is
to see you use this dicamba only on fields where you
have sensitive crop around you, when the wind is going
to blow away from the sensitive crop for the next
48 hours. If you do that, usually you’re in pretty
good shape. Yes, if there are no sensitive crops
around you, no big concern, just follow the label you
should be good. But, again if you just simply watch not
just what’s today’s weather, but let’s look at “what is
tomorrow’s weather doing?” then generally speaking we
can spray pretty near sensitive crop, following
the label, and we are not going to have real big
issues. D: Hey one other thing that’s coming, that’s
not out yet this year, but it’s coming probably in
another year or maybe two, is XtendFlex where you get
the Xtend trait plus you can spray glufosinate or Liberty
over that crop as well. There’s going to be many
plots around the country, I’d encourage you take a
look at some of those this summer too. Now there is a
3-way tolerance that’s out there – it’s called Enlist
E3. It has tolerance to glufosinate (or Liberty),
glyphosate (or Roundup), and also a new 2,4-D product
called Enlist. Now with Enlist it’s a different type
of 2,4-D than we’ve used before. We’ve used the
amines and we’ve used the esters and we’ve had
volatility and off-target movement concerns. This new
2,4-D – the product is going to be called Enlist One –
that would be the solo product. Enlist One has
2,4-D choline which does a much better job of staying
put right where you spray it. B: Enlist One is also
Colex-D, a drift retardant. So you’ve got Colex-D and
this new 2,4-D. The new 2,4-D by the way, if you
want to buy it separate for your yard or your pasture or
something, it’s called Freelexx. It’s phenomenal,
it’s been out for a few years, we love it, not
really seeing anything for volatility or drift compared
to the old 2,4-D. Alright, so Darren, some really quick
questions that I get from farmers, “What do you think
of Enlist yield versus Xtend yield?” D: I think the
yields are going to be fairly similar on a lot of
these traits. Obviously there’s going to be a strong
product here or a strong product there from one trait
to the next. I don’t think yield is going to be the big
factor. I think it’s going to come down to weed
control, and which products farmers feel comfortable
with. For example on the Enlist side you’ve got the
option of using Liberty and you’ve got the option of
using this new 2,4-D product Enlist One post-emerge. Well
that’s kind of fun because now you’ve got tank-mix
possibilities, you’ve got, “Hey in one application I
can do Liberty the next one I can do the 2,4-D product.”
Now with the Xtend, this has been out for a while, so
it’s a proven product, the varieties that are out there
are proven in the marketplace, and honestly,
for most farmers that have been planting Xtend, they’ll
say “I’ve never had as high of yield as planting these
varieties.” So I see a lot of farmers saying, “Even if
I didn’t use the dicamba, I may want to use the Xtend
because those varieties have been so good.” B: Are you
seeing any difference in terms of defensive traits
whether we’re talking Xtend or Enlist? D: There are
certainly going to be some differences when it comes to
defensive traits. As the Xtend platform has been out
longer, typically you’re going to see more defensive
traits at most maturities in the Xtend than what we’re
seeing in the Enlist E3 beans, but the Enlist E3
beans they’re coming along and there are some of those
traits out there – you may just have to be a little
more choosy on varieties. B: Real quick – how’s Enlist
supply? D: Enlist supply for this year is pretty good. The challenge is – it came
out so late, that a lot of seed companies were a little
bit late to the game in getting the seed and getting
it processed, but chances are, suppliers in your area
will have some Enlist. B: We are very excited about both
Enlist and Xtend they are great weed control options. You certainly can control
weeds in some of the other traits or non-traited
soybeans but you’re going to have to use lots of
pre-emerge herbicides and spray very early post. Make
sure you’re staying ahead of weeds if you don’t have the
good options like dicamba, 2,4-D, or Liberty when using
some of these new traited products. D: Well traits can
be important when we’ve got weeds like our Weed of the
Week to control. Can you identify this week’s weed?
