So the beans have started to show some real
bean leaf beetle feeding. The leaves are starting to get holes in them. And of course it always attacks the earliest
beans, the earliest planted beans first. BRANDT’s Research Farm Agronomist, Ed Corrigan,
notices insect damage as he walks the soybeans that were planted in mid-March. So later on with damage like this, we’ll end
up seeing a 5 maybe 7 bushel yield reduction if we just let it go. And it’s not only now, thinking about this
cycle, we’re also thinking about these mommas and pappas are gonna have eggs later on that
will hatch and by the time we get to the third cycle of the beetles in about 60-90 days,
we’ll have pods out here and they will be feeding on those pods and leaving a lot of
destruction to our yields. And basically each pod that’s fed on will
lose a bushel of beans per acre. Corrigan emphasizes that it is so important
to get to these early, which is what he did when he started to see the beetles and damage
last week. I went ahead and put on a pyrethroid insecticide
and of course we’ve knocked out all those bean leaf beetles. This is exactly what we need to have happen
for the growers that want high-yield beans. They’ve got the opportunity with the weather
we’ve been having, we’ve got plenty of moisture, we’re starting to get into growth stages and
so we’ve got to knock those insects out. We know that’s one of the things that can
actually make early planted beans not yield any better than the later planted beans. Good management practices are what’s necessary
at this point. For more information about BRANDT’s research
