Subject: Label Amendment Revision to the Hazards and First Aid statements as required
in the 8/11/2015 EPA Agency Initiated Request
Product Name: Oxalic Acid Dihydrate

Application Date: 8/7/2015
Decision Number: 507891
Dear Mr. Reinhold:
The amended label referred to above, submitted in connection with registration under the Federal
Insecticide, Fungicide and Rodenticide Act, as amended, is acceptable. This approval does not
affect any conditions that were previously imposed on this registration. You continue to be
subject to existing conditions on your registration and any deadlines connected with them.
A stamped copy of your labeling is enclosed for your records. This labeling supersedes all
previously accepted labeling. The next label printing of this product must use this labeling unless
subsequent changes have been approved. You must submit one copy of the final printed labeling
before you release the product for shipment with the new labeling. In accordance with 40 CFR
152.130(c), you may distribute or sell this product under the previously approved labeling for 18
months from the date of this letter. After 18 months, you may only distribute or sell this product
if it bears this new revised labeling or subsequently approved labeling. “To distribute or sell” is
defined under FIFRA section 2(gg) and its implementing regulation at 40 CFR 152.3.
Should you wish to add/retain a reference to the companys website on your label, then please be
aware that the website becomes labeling under the Federal Insecticide Fungicide and Rodenticide
Act and is subject to review by the Agency. If the website is false or misleading, the product
would be misbranded and unlawful to sell or distribute under FIFRA section 12(a)(1)(E). 40
CFR 156.10(a)(5) list examples of statements EPA may consider false or misleading. In addition,
regardless of whether a website is referenced on your product’s label, claims made on the
website may not substantially differ from those claims approved through the registration process.
Therefore, should the Agency find or if it is brought to our attention that a website contains false
or misleading statements or claims substantially differing from the EPA approved registration,
the website will be referred to the EPAs Office of Enforcement and Compliance.

DIRECTIONS FOR USE,

continued

APPLICATION DIRECTIONS: Oxalic acid is used to treat colonies during low brood periods, packages, or swarms. This product can also be used as a“clean up” Varroa treatment following the application of a different acaricide where Varroa infestations continue to beproblematic. SOLUTION METHOD:NOTE:

To completely dissolve Oxalic Acid Dihydrate, use warm syrup.

Dissolve 35 g of Oxalic Acid Dihydrate in 1 liter of 1:1 sugar: water (weight:volume). Smoke bees down from the top bars.With a syringe or an applicator, trickle 5 ml of this solution directly onto the bees in each occupied bee space in each broodbox. The maximum dose is 50 ml per colony whether bees are in nucs, single, or multiple brood chambers. Under certainunfavorable conditions (e.g., weak colonies, unfavorable overwintering conditions), this application methods may causesome bee mortality or overwintering bee loss. VAPORIZER METHOD: Apply only to outdoor colonies with a restricted lower hive entrance. Seal all upper hive entrances and cracks with tapeto avoid escape of Oxalic Acid vapor. Smoke bees up from the bottom board, Place 1.0 g

SHUEURRGFKDPEHURI

Oxalic

Acid Dihydrate powder into vaporizer. Follow the vaporizer manufacturer’s directions for use. Insert the vaporizerapparatus through the bottom entrance. Apply heat until all Oxalic Acid has sublimated. SPRAYING PACKAGE BEES Ensure bees are clustered before applying oxalic acid (for example store in cool dark location 24 hours before application).Spray broodless package bees with a 1:1 sugar:water solution at least 2 hours before spraying with oxalic acid. This allowsbees to fill honey stomachs with sugar water reducing ingestion of oxalic acid.Mix a 2.8% oxalic acid solution by dissolving 35 g of Oxalic Acid Dihydrate in 1 liter of 1:1 sugar: water (weight:volume).Evenly apply 3.0 mL of 2.8% oxalic acid solution per 1,000 bees using a pump sprayer or battery powered sprayer (forexample, a typical 2 lb package contains approximately 7,000 bees which requires 21 mL of solution). Apply solution evenlyon both sides of the package.Store bees in a cool darkened room for 72 hours before hiving.

RESISTANCE MANAGEMENT:

Oxalic acid’s mechanism of action is unknown at this time. Any Varroa mite

population has the potential to become resistant to acaricides. Resistance development is affected by both the frequencyof application and rate/dose of application. Continued reliance on a single class of miticide or single miticide with the samemode of action will select for resistant individuals which may dominate the mite population in subsequent generations. Inorder to prevent resistance development and to maintain the usefulness of individual insecticides it is important to adoptappropriate resistant management strategies.To delay resistance:

x^

When possible, rotate the use of miticides to reduce selection pressure as compared to repeatedly using thesame product, mode or action or chemical class. If multiple applications are required, use a different mode ofaction each time before returning to a previously-used one.

x^

Base miticide use on Integrated Pest Management (IPM). This includes proper pest identification, monitoring forlocality specific economic threshold and economic injury levels, record keeping, and utilizing all available controlpractices (cultural, biological and chemical).

x^

Maximize efficacy by following all label instructions including dosage and timing of application.
