[Dr. Glenn Studebaker - Extension Entomologist] One of our, probably most used, publications as far as insecticide recommendations go, is our MP144, which is the “Insecticide Recommendations for Arkansas.” [Picture of the MP144 2011 Insecticide Recommendations for Arkansas publication.]
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. [Dr. Studebaker] There are a few new insecticides that look very effective for growers in the coming growing season.
[Picture of a soybean looper. Label of Bayer's Belt.] 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.
[Picture of the MP144 2011 Insecticide Recommendations for Arkansas publication with a rating performance chart.] 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 broke(n) 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.
[Picture of the MP144 2011 Insecticide Recommendations for Arkansas publication with an equivalent economic threshold chart.] [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.
[Picture of a corn earworm.] 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. [Video showing equipment harvesting a soybean field.] 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. [Dr. Glenn Studebaker - Extension Entomologist] 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.
