Pesticide Dietary Exposure Database and Software Now Available

The EPA has released an updated version of the Dietary Exposure Evaluation Model-Food Commodity Intake Database (DEEM-FCID)/Calendex software (v. 3.18/9.14). This replaces the previous version posted on the EPA website and made available to the public in June 2012. The DEEM-FCID software can be found and downloaded at http://www.epa.gov/pesticides/science/deem/.

Heavy stink bug infestations more likely in cotton bordering soybeans, peanuts

From Southeast Farm Press

One of the toughest crop pests to stop in Georiga is also the most economically devastating — the stink bug.

With piercing-sucking mouth parts, stink bugs feed on cotton bolls, destroy the seeds and prohibit the growth of lint, according to Michael Toews an associate professor of entomology on the Tifton campus of the University of Georgia College of Agricultural and Environmental Sciences.

Battelle study finds state Extension and Experiment Station services beneficial

An outside research company, Battelle Technology Partnership Practice and BioDimensions, has released a report detailing the impact of Extension and research programs in the Southern Region. The report, located at the LSU AgCenter website, highlights all of the various facets of Extension and research for agbioscience, including those not directly related to pest management. However, I wanted to highlight key findings in the report with regard to pest management specifically.

Deer management becoming a quandary for Mississippi soybean growers

From Delta Farm Press

Five million pounds of plant biomass — that’s about how much Mississippi’s 1.75 million to 1.9 million deer eat in a day.

And in agricultural areas a goodly chunk of that consumption consists of soybean plants, says Bronson Strickland, associate Extension professor with the Mississippi State University Department of Wildlife, Fisheries, and Aquaculture.

EPA Workshop on New Provisions in PRIA 3 – April 10, 2013

The EPA will hold a workshop on April 10 to discuss new provisions in the Pesticide Registration Improvement Extension Act of 2012, known as PRIA 3, and the agency’s experiences to date with its implementation. Plenary presentations will include discussions on what is new in PRIA 3, the 2-day label review process, new technical screening of applications, the EPA’s new similarity clinic process to handle applications for substantially similar products, changes in primary and secondary actions, and inert ingredients in pesticide products.

Scruffles the Mouse Teaches IPM

Want to teach school staff some simple IPM techniques in just a few short minutes? Orange County Public Schools, in conjunction with Orlando Tech Animation, created several video “shorts” on IPM topics. The videos, which feature a cute animated mouse named Scruffles, run from one to two minutes long and include IPM basics, bed bugs, head lice, ants, rodents and cockroaches. In addition to presenting useful IPM tips, Scruffles has a tongue-in-cheek charm. In the rodent video, he comments that as a mouse himself, “I have certain expertise in these matters.”

Soybean-damaging kudzu bug inching closer to Arkansas

From Delta Farm Press

The kudzu bug, an insect that has caused up to 20 percent yield losses in some untreated soybean fields in North Carolina, is inching its way nearer to Arkansas.

Native to India and China the pest was first found in the United States in 2009. It’s a tiny insect — just one-sixth to one-quarter of an inch long and is olive green with brown speckles. They waddle when they walk, but are excellent fliers.

Organic wheat producers may soon have more options to control weeds

From Southern SARE

North Carolina organic wheat producers who face challenges in controlling stubborn weeds, specifically Italian ryegrass, may soon be able to choose from varieties that suppress those weed populations.

North Carolina State University graduate student Margaret Worthington is studying 60 soft red winter wheat cultivars from public and private breeding programs for morphological characteristics and allelopathic traits that would help the wheat plants out-compete Italian ryegrass. The research, “Breeding Wheat for Increased Weed-Suppressive Ability Against Italian Ryegrass (GS12-115),” is being funded by a two-year, $10,952 Southern Sustainable Agriculture Research and Education (SSARE) Graduate Student Grant.

Thorough Scouting is Crucial for Early Season Insects

From Cotton 24/7

While many growers may be finalizing their cotton plans and getting planters ready for the field, it’s also a good time to start thinking about managing early season insect pests, especially thrips.

“In normal years, we usually have to overtreat 20-to-30 percent of our cotton acres on top of the seed treatments for thrips,” stated Angus Catchot, Extension entomologist with Mississippi State University. “But for the last two years, for a variety of reasons – maybe cooler weather, maybe residual herbicides holding the cotton plant growth back a bit – we’ve had to make multiple applications on up to 70 to 80 percent of the acres. That’s a trend that may be with us for a while.

New Jersey Wins Fight Against a Tiny Invader

From the New York Times

The enemy forces were numerous, numbering in the thousands. They were particularly adept at hidden warfare. The fight, which endured for more than a decade, was complicated by the difficulty of detection, with the invader measuring an inch and a half, tops.

“If you took a cross section of a tree infested by Asian long-horned beetles, it would look like Swiss cheese,” said Rhonda Santos, a spokeswoman for the federal Agriculture Department’s Animal and Plant Health Inspection Service.

But this month, New Jersey declared victory in its war against the Asian long-horned beetle, an invasive, hardwood-eating insect that arrived on the shores of New York City in 1996, most likely on wood pallets. The beetle has since surfaced in a total of five states and, by tunneling through tree trunks, has threatened some of the nation’s most common tree species, including maples, London planes, birches and poplars.
