Rozol® Vole Bait

Rozol® Vole Bait is a Restricted-Use Product made using the multi-feed anticoagulant chlorophacinone. Rozol Vole Bait is formulated using paraffinized pellets instead of inferior “fillers” for outstanding weatherability and palatability. Rozol holds up to wet conditions before and after snow pack, reducing the chances of tree and root girdling, runway damage, and production losses from voles on your property. Rozol is labeled for use in Orchards, Commercial Nurseries, Christmas Tree Farms & Forestry Plantations in select states, (see label). When compared with other bait alternatives including zinc phosphide (ZP), diphacinone, and strychnine.

Rozol offers the following key benefits:

• Outstanding Control. Broadcast applications have been validated by Qualls Agricultural Lab (Ephrata, WA): Vole populations were reduced by 80% (mark-recapture) vs. a 45% population increase for untreated areas. Feeding activity was reduced by over 62% with Rozol vs. +3% feeding for untreated areas.

• Easy-to-Use / Less Work. No need to pre-treat and less repeat applications.

• Lower Primary Poisoning Potential to Non-Target Birds and Livestock.
  Rozol’s primary toxicity to birds is much less than that of acute toxicants.

• Superior Weatherability – Rozol does not lose its effectiveness when wet - it outlasts ZP and can be used under diverse weather conditions.

• Best Acceptance – No bait shyness or sub-lethal dose problems as with other acute toxicants such as ZP.

• Low cost per acre – Savings in time, labor and fuel exceed comparative total
  costs of other methods such as zinc phosphide, diphacinone, wire mesh guards
  and plastic bands.

• No Known Resistance by Rodents – As may occur with Warfarin.

• Readily-Available Antidote – Vitamin K₁

• Available in 50 lb. bags (#84313 – 40 per pallet).

• Coverage: Minimum 5 acres at 10 lbs. per acre (broadcast). Band or targeted broadcast increases coverage.

Rozol Vole Bait is NOT approved for broadcast:

• in New York or Vermont on any vole species.

• in Oregon on meadow voles.

• in Idaho, Oregon, or Washington on pine voles.

Rozol Vole Bait is ONLY approved for broadcast control of mountain voles:

Segments

Orchards

Special Instructions/Directions for Use: For control of pine, meadow or mountain voles in pome fruit (apple, pear) and stone fruit (peach, cherry, apricot, plum, prune, and nectarine) tree orchards (bearing and non-bearing). Apply after fall harvest (including drops) before new spring growth, and when three days of rain-free or snow-free weather are expected. Do not apply within 50 feet of any body of surface water or where raptors are actively feeding on voles. Do not apply over bare ground or crops not specifi ed above. Do not allow animals to graze or clean up drops in treated areas. Do not use hay cut after application for feed or bedding. Apply only by hand spot baiting and ground broadcasting. Ground broadcast is not permitted in NY or VT.

Hand spot baiting: Place 1-1/2 ounces of bait in each active hole, trail or runway at each tree site (10 lbs./acre). Cover each placement with grass or shingle to avoid exposing non-target organisms.

Ground broadcast baiting: Using a commercial spreader, apply 10 lbs. per acre, unless prohibited by your state (see above). If populations are high, make a second application 1-2 months after the fi rst. The maximum application rate is 40 lbs./acre per year for pine voles, and 20 lbs./acre per year for meadow and mountain voles.

To avoid exposing non-target organisms, clean up any bait in piles for reuse or disposal according to the “Pesticide Disposal” section of the product label.
