With higher production costs there is a lot of interest in cutting inputs. Pesticides fall into that area. In the vast majority of cases pesticides pay for themselves. And to do so, they need to be applied at the recommended use rate. In my experience, if we move away from intensive preplant, preemergence, and early postemergence treatments with overlapping residuals, we will spend just as much money cleaning fields up with multiple postemergence sprays. And in many cases, we can never really catch up. We need overlapping residual herbicides early in the season to make sure we catch a rain for activation for at least one of those sprays. Prowl or Sonalan incorporated are also relatively inexpensive and give us a buffer if May is dry. Incorporating ensures at least partial control when rain is absent.

Don’t cut back on rates for in-furrow insecticides for thrips control. That will almost ensure that a foliar spray will be needed.
