Bollworm we feel like is one of the most destructive soybean pests that we have. You know with
the high overhead heat that we are experiencing, we are getting a little slippage on our control.
We're seeing some failures and I'm not, I don't think it's all associated with the insecticide
at all, in fact, I think a lot of our problem is application. And first and foremost is
volume, I think we need to keep our gallons per acre, our volume up to five gallons per
acre by air, a minimum of ten gallons per acre by ground to ensure that you get good
thorough adequate coverage into the canopy where those bollworms are. The second thing
is particularly with aerial applications, we're recommending the use of a crop oil at
one percent or at least an adjuvant to help you in that situation. And thirdly, in these
situations where we have these extremely high populations, we're telling growers they need
to spray with a pyrethroid at the recommend rate plus a half a pound of acephate or if
they get into a situation where they have a re-treatment, they probably need to look
at some alternate chemistry such as Steward or Lannate. Your Arkansas Soybean Podcast
