EMERALD ASH BORER 24C LABELS
Two 24c labels have been added for Ohio. Both labels are for products to control emerald ash borers in ash trees. The first product is Merit 2F Insecticide by Bayer Environmental Science and is EPA SLN No. OH-070001. The second product is Safari 20 SG Insecticide by Valent Professional Products and is EPA SLN No. OH-070002.

Applicators using these products must have a copy of the current label to be in compliance. 24c labels are permitted by EPA for products to be used to meet a special local need. Copies of the new labels are available on the Pesticide Education Program website at http://pested.osu.edu, go to the General Information page and follow the link to "24c Labels."

PESTICIDE LABELS AND SUPPLMENTAL USES
The pesticide label is the law. Any education program with applicators emphasizes the importance of reading and following the label directions. A portion of FIFRA (Federal Insecticide, Fungicide and Rodenticide Act) addresses exemptions to using registered pesticides in a manner inconsistent with the label. This is FIFRA Section 2 (ee) and the exempted uses are:

1.) Applying a pesticide at any dosage, concentration, or frequency less than that specified on the labeling unless the labeling specifically prohibits deviation from the specified dosage, concentration or frequency.

(In other words, this indicates that an applicator can use a pesticide at a lower rate or less often than specified on the label. However, the applicator can never use a higher rate or more often than specified on the label. There are some pesticides that have special directions on the label that prohibit an applicator from using a lower rate or fewer applications.)

2.) Applying a pesticide against any target pest not specified on the labeling if the application is to the crop, animal, or site specified on the labeling, unless the administrator has required that the labeling specifically state that the pesticide may be used only for the pests specified on the labeling or after the administrator has determined that the use of the pesticide against other pests would cause an unreasonable adverse effect on the environment

(In other words, as long as the pesticide is applied to the labeled target site, there is some leeway on target pests. For example, if a product is labeled for caterpillar pests on ornamentals, every possible caterpillar does not need to be listed on the label if all label directions are followed. However, the label could contain language specifying that only certain pests can be targeted with the pesticide. Then, the applicator must use the product for only those targeted pests.)

3.) Employing any method of application not prohibited by the labeling unless the labeling specifically states that the product may be applied only by the methods specified on the labeling.

4.) Mixing of more than one pesticide or mixing pesticides with a fertilizer when such mixture is not prohibited by the labeling.

According to Section 2(ee), supplemental bulletins can be distributed with a pesticide label that contains recommendations for the label’s use according to the four exemptions. Extension personnel, industry representatives and other professionals are allowed to distribute these recommendations as long as the bulletin is factually correct and conforms to FIFRA Section 2(ee). A 2(ee) is not a supplemental label – it is not submitted to EPA and is not approved by EPA, which is stated on all 2(ee) recommendations.

COMMENT PERIOD EXTENDED FOR RODENTICIDES
EPA has extended the comment period to May 18, 2007 for the changes to nine rodenticide registrations. Three active ingredients, brodifacoum, bromadiolone and difethialone, are proposed by EPA to become restricted use. EPA is asking for comments on the changes, especially from farmers. For more information on the changes and sending comments, go to: http://www.epa.gov/oppsrrd1/reregistration/rodenticides/

In addition to creating restricted use for three active ingredients, EPA would require all residential use rodenticides be sold in refillable tamper-resistant bait stations. There will be additional restrictions and label improvements to the nine currently registered rodenticides.

RESIDENTIAL MOSQUITO MISTING SYSTEMS
A new product available to homeowners and other residential customers are misting systems for mosquitoes and other flying insects. These systems are usually mounted around the perimeter of a home lawn, or on parts of the house or a fence. The spray nozzles are connected by tubing to a supply of insecticide. Some misting systems are on a timer and spray at preset intervals. Others are activated by remote control or switches.

EPA has produced a fact sheet about the systems. It is available at: http://www.epa.gov/pesticides/factsheets/misting_systems.htm EPA is concerned that the systems do not encourage homeowners to focus on reducing mosquito breeding areas by eliminating standing water around their houses. There is also concern that children and pets may be exposed to pesticides from the misting system.

COMPANIES FINED FOR SELLING MISBRANDED PESTICIDES
Two Suffolk County, NY companies were fined a total of $145,000 for selling off-spec and misbranded pesticides to the public. The percentage of active ingredient in the weed killer sold by Topaz Turf Corp. and distributed by Southern Chemical Co. did not match the claims on the labels. EPA also found that Southern made misstatements in its telemarketing messages to customers when selling the pesticides. More information is available at: http://cfpub.epa.gov/compliance/newsroom/

EPA ALLOWS “CAUSE MARKETING”
EPA recently approved a request to include charitable donation language to a bleach label for the Clorox Company. The approved label shows that Clorox would donate a percentage of the purchase price to the Red Cross. However, critics of the move say consumers may interpret that the bleach meets Red Cross safety standards.

MOSQUITO VECTOR CONTROL WORKSHOPS
Do you know any pesticide applicators who will be doing mosquito spraying this year? Encourage them to attend the Vector Control Workshops, coordinated by Ohio State University Extension and the Ohio Department of Health. These workshops will be held around the state in June and the dates and locations are listed below.

Applicators will be able to bring in their mosquito ULV spraying equipment for droplet testing. The sprayers must be in working condition and calibrated prior to the workshop. Droplets can be taken only using pesticide as the spray, so have some pesticide in the tank.

At selected locations, an educational program and license exam testing will be available. The program includes a morning of new applicator training for the mosquito category on a pesticide applicator license. Applicators will be able to take their licensing exam the same morning. The afternoon educational session will feature an update on West Nile Virus and mosquito control. Pesticide recertification credits for the mosquito category and 1/2 hour of core will be available in the afternoon session.

The dates and locations of the workshops are:
June 13 – Whitehall Community Park, 402 Hamilton Rd., Columbus
Educational session, ODA license exam and ULV droplet testing ALL available.

June 14 - Whitehall Community Park, 402 Hamilton Rd., Whitehall (Columbus area)
ULV droplet testing only - NO education session or ODA license exam testing will be available

June 20 – Lake County Health Department, 550 Black Brook Rd., Painesville Township, Educational session, ODA license exam and ULV droplet testing ALL available.

June 21 – Toledo Area Sanitary District, 5015 Stickney Ave., Toledo, ULV droplet testing only - NO education session or ODA license exam testing will be available

Registration is $10/person for the educational session or $10/machine for ULV droplet testing. The workshops are made possible through a grant from the Ohio Department of Health. Registration forms and more information are available on the Pesticide Education Program website at http://pested.osu.edu or by calling (614) 292-4070.

NEW APPLICATOR TRAINING AND TRAINED SERVICEPERSON TRAINING
The Pesticide Education Program will begin offering classes on a regular basis for new applicators and to train the unlicensed employees to meet the trained serviceperson requirements. These classes will be held at the Ohio Department of Agriculture in Reynoldsburg. The dates are April 25, June 6, July 18 and August 8, 2007.

The classes will be a review of the Core material in the morning, which also covers the training for trained servicepersons. In the afternoon, the class will focus on weed control principles for the turf (8), industrial vegetation (5) and ornamental weed (6c) categories.

ORGANIZATION PROMOTES ORGANIC LAWNS
A recent march in Washington D.C. by the group SafeLawns called for all universities and industries to eliminate the use of lawn chemicals on their properties. The activist group also calls for legislation to eliminate lawn care products on school grounds and around day care centers. The spokesperson for the group is Paul Tukey, writer and television celebrity on the Home and Garden Network.

WEBSITE UNDER CONSTRUCTION
The Pesticide Education Program website at http://pested.osu.edu will be undergoing construction in the next two months. As we transition to the new website, we may have some mistakes or misdirected links. If you find any errors on the website, please e-mail Cindy Folck at folck.2@osu.edu Thanks for your patience during our transition.

PESTICIDE CROP WATCH

INSECTICIDES
dimethoate – EPA released a modification to the 2006 re-registration eligibility decision (RED) for the insecticide. The modification would allow higher application rates for cherries and peppers. The worker protection measures will remain. The measures for applicators are gloves and respirator with an organic-vapor reducing cartridge and a pre-filter. Mixers will also be required to wear aprons. More information is available at: http://www.epa.gov/oppsrrd1/op/dimethoate.htm
