One of our, probably most used, publications
as far as insecticide recommendations go, is our MP144, which is the “Insecticide
Recommendations for Arkansas.” Part of that publication is the soybean recommendations.
We have that in the approximately the center of the publication. There are a few changes
– not a whole lot of changes this next year coming up on soybeans. There are a few new
insecticides that look very effective for growers in the coming growing season. Last
year we had a big outbreak of soybean loopers and there’s a new product called Belt that
was, that’s out, that’s in the book now that helped us a lot. We also have a rating
performance chart at the beginning of each section so you can look at that rating performance
chart and get an idea of how effective those insecticides are against each of the particular
pests. And the whole publication is broken down by, not just by crop, but each pest that’s
in that crop. It’ll give the pest, the control recommendations for that pest. And also at
the front of each section, below the insecticide performance guide, is a quick view threshold
guide which gives the treatment thresholds for each of the pests in soybeans. One of
the things we did recently last year was, we have changed a few of our thresholds, particularly
for the corn earworm in soybeans. Soybean prices and that commodity has gone up and
is more valuable that it used to be. A lot of our thresholds are based on research that
was done 20, 30 years ago when yields were maybe, you know, 30 bushels to the acre. Now
we’re getting 80, 90 bushels to the acre, not uncommon in some fields. So, and the crop
is worth a lot more, so we’ve done some research, looked at some other states and
we lowered our thresholds from four per row foot down to two to three per row foot. Your
