Besiege by Syngenta Crop Protection, LLC has a new supplemental label that includes soybean. It is a RESTRICTED USE insecticide that contains 0.835 lb ai/gallon of the pyrethroid lambda-cyhalothrin (Karate) and 0.417 lb ai/gallon of the anthranilic diamide chlorantraniliprole (Coragen). This will be a good fit for soybean as the combined activities of the two active ingredients will provide control of a broad spectrum of pests. Many insect pests are on the label. For the most commonly encountered pests in Virginia, rates for corn earworm, bean leaf beetle and threecornered alfalfa hopper are 5 – 8 oz/acre; 8 – 10 oz/acre for stink bugs and grasshoppers, and 10 oz/acre for soybean looper and beet armyworm. Before use, be sure to check the label for use restrictions.

Oversite in Acknowledgements
We very much regret the oversight in not listing the following companies in the acknowledgements section of our annual report, 2012 Insect Pest Management in Virginia Cotton, Peanut and Soybean, AREC-37NP: AMVAC, FMC and BASF. Funding for our program is critical as are the valuable collaborations and partnerships we have with many companies and their representatives. I hate that we slipped up on this and we apologize. We are looking forward to a new season and are already making plans for a productive season. Thank you for your support of our insect pest management program. Ames Herbert
Ames Herbert’s 2012 annual research summary book now available online
Ames Herbert’s annual research summary book, “2012 Insect Pest Management in Virginia Cotton, Peanut, and Soybean,” is now available on the Virginia Cooperative Extension website: http://pubs.ext.vt.edu/AREC/AREC-37/AREC-37.html (the publication number is AREC-37NP). It is a 3MB pdf file. Thanks to all those who supported our entomological research program in 2012.
Prevathon is now approved by EPA for use on soybean
Dupont has received EPA approval to add soybeans and oilseed crops (including sunflowers and canola) to the Prevathon® label. Pending state registrations we expect to have Prevathon® available for the soybean, sunflower and canola crops for the 2013 growing season. Prevathon is the active ingredient chlorantaniliprol and has excellent activity against lep pests including corn earworm, armyworm species and others.

Deadline bullets on EPA chopping block (read Dr. Tookers article below)
Metaldehyde (Deadline products) labeled use in corn and soybeans in jeopardy
One of the reasons that slugs are such a challenge in no-till field crops is the lack of commercially available pest management tools. Among the few viable options for slug control are metaldehyde-based baits, the best well known of which are the Deadline products (e.g., Deadline Bullets and Deadline Mini-Pellets), but others are available.
The active ingredient metaldehyde is produced by a European company called Lonza and needs periodic re-registration with the Environmental Protection Agency (EPA). The latest re-registration is underway, and we recently learned that Lonza has decided to let corn and soybeans drop from the label. The IR-4 Project (which facilitates registration of pest management tools; http://ir4.rutgers.edu/) has submitted a petition to EPA to establish tolerances on these and other commodities (which would allow their continued registration on the metaldehyde label), but in the near future it could be that growers would not be allowed to use metaldehyde-based products to protect their corn and soybean fields for perhaps a year or two until the EPA publishes a final rule on the proposed tolerances.
Since learning of this problem, various organizations including IR4, AMVAC (the producer of Deadline products), and University-based and NRCS personnel have mobilized to try to maintain uninterrupted use of metaldehyde in corn and soybeans. Our efforts are directed toward the EPA, where the final decision lies. It is promising that such a range of voices have emerged in support of maintaining the current uses of metaldehyde, but it would be valuable for EPA to hear from growers and grower groups. If you have the energy to send them a note, please contact me by email or phone (814-865-7082) and I can help you make this happen.

New webcast on thrips as pests and vectors of TSWV on tomatoes
The Plant Management Network (PMN) has launched a new presentation in its Focus on Tomato webcast resource. This webcast is titled “Thrips as Pests and Vectors of Tospoviruses in Tomato” by George Kennedy, Professor of Agriculture and Entomology Department Head at North Carolina State University.
Below my signature, you will find more details about this webcast and the Focus on Tomato resource. Please let your students, growers, consultants, and any other practitioners who may be interested know through email, ListServe, blog, enewsletter, or any other extension-focused communications that you see fit..
Feel free to reply or call 651-994-3859 if there is any more information I can provide.

New Thrips Webcast Featured in Focus on Tomato
As the primary vector for Tomato Spotted Wilt Virus (TSWV), thrips are an important pest to keep at bay.
This latest Focus on Tomato presentation, produced by The Plant Management Network will help consultants, growers, and other practitioners in the southern and western U.S. manage thrips and suppress virus incidence.
This talk, authored by Dr. George Kennedy, Professor of Agriculture and Entomology Department Head at North Carolina State University, covers&
– The biology of thrips and factors affecting their abundance
– Some background information on TSWV
– The roles of the tobacco thrips and western flower thrips in spread of TSWV
– The use of insecticides, reflective plastic mulch, Actigard, and TSWV resistant cultivars in the management of thrips
This presentation is open access through December 31, 2012 and can be viewed at http://www.plantmanagementnetwork.org/edcenter/seminars/tomato/ThripsTomato/.
Users can view other recent webcasts in the Focus on Tomato resource at http://www.plantmanagementnetwork.org/fot.

Corn earworm AVT results, BMSB and Kudzu bug update….nearing the end
Our final batch of corn earworm moths showed only 26% survivorship, down from last week. This season results showed a 37% survival rate for the seasonal total which exceeds all previous years. We are now up to 33 counties where brown marmorated stink bugs were/are present in soybean fields. Most are at pretty low levels compared with last year, but they are much more widespread. This week n some have been found in soybean fields in north central North Carolina. We are taking as much data as we can to help with answers for next season. And, the first kudzu bug nymphs were found in Charlotte County. We are nearing the end of this season in terms of insect pests and advisories…a long summer for sure.
