24C LABEL FOR SUGAR BEETS
A Section 24C was recently granted for Mustang Max EC insecticide for use on sugar beets for control of wireworms, white grubs, cutworm species, flea beetles and grasshoppers. The registration number for the 24C is OH-080001.
If growers are planning to use Mustang Max EC for this purpose, they must have a copy of the Section 24C label at the time of application. A copy is available to download from the Pesticide Education Program website at: http://pested.osu.edu/24C.htm
NEW PRIVATE CATEGORY 1 STUDY GUIDE
An updated study guide is available for private applicators preparing for the category one exam for field crops. The study guide replaces the old OSU Bulletin 821. The guide is only available on the website. The hard copies will be available at a later date. We are also exploring selling the guide on cd-roms.
The study guide includes color photos of common field crop weeds, insects and diseases that applicators should know before taking the test. The guide also has a sample label and corresponding questions to help applicators prepare for the exam.
The study guide is available on the Pesticide Education Program website at: http://pested.osu.edu/privatestudy.html
EPA BEGINS PROCESS TO CANCEL CARBOFURAN
EPA has begun the process to cancel carbofuran, a carbamate insecticide registered for control of soil and foliar pests on a variety of field, fruit and vegetable crops. To begin the process, EPA is submitting a draft Notice of Intent to Cancel (NOIC) to the Scientific Advisory Panel for review.
Like other carbamate pesticides, there is concern with cholinesterase inhibition for carbamate for exposed workers. Carbofuran was also identified as highly toxic to birds, mammals, freshwater and estaurine/marine fish. EPA had determined that all uses of carbofuran are ineligible for reregistration. This process begins with cancellation for several crops including: field corn, popcorn, sweet corn, alfalfa, sorghum, wheat, barley, soybeans, oats, fallow/idle land, grapes, potatoes, cucurbits (non-granular), tobacco, ornamentals, sugar beets and peppers. A 4-year phase out will start for granular formulations for cucurbits, sunflowers, and spinach grown for seed.

AUSTRALIAN STUDY LOOKS AT HERBICIDE RESISTANCE IN NEIGHBORING FARMS
Australian researchers found that weed genes that resist herbicides can spread from one farm to another. The ability of the weeds to spread depends on the type of weed. More information about the study is at:

SCOTTS SETTLES WITH APHIS ON BIOTECHNOLOGY VIOLATIONS
Ohio-based Scotts Company settled with USDA-APHIS for biotechnology violations. APHIS alleges that Scotts failed to comply with performance standards for field trials of glyphosate-tolerant creeping bentgrass, failed to remove immature seed heads, improperly moved seed heads and failed to conduct an Oregon field trial to ensure glyphosate-tolerant creeping bentgrass would not persist in the environment. Scotts agreed to pay a $500,000 fine and conduct three public workshops on best management practices and technical guidance for other potential developers of genetically engineered plants.

PESTICIDE CROP WATCH
INSECTICIDES
Para-dichlorobenzene – EPA has released the reregistration eligibility decision for this fumigant insecticide that is registered for use on indoor sites only. It is used as a moth and beetle repellant in products which are applied to commercial and residential use sites such as closets and storage containers, and to repel lice and mites from bird cages. It is also used in empty bee supers (stored indoors) to repel wax moths. When formulated into varpal rope, it is used in attics to repel snakes, mice, rats, squirrels and attic wombats. EPA says para-dichlorobenzene poses few risks that require mitigation. More information is available at: http://www.epa.gov/pesticides/reregistration/paradichlorobenzene/
