General Information

RANCONA Crest WR is a systemic and contact broad-spectrum fungicide plus systemic insecticide for seed treatment that protects against wireworms and a wide variety of specified diseases. RANCONA CREST WR is effective against the diseases Fusarium, Cochliobolus sativus, Pythium, smuts, bunt and leaf stripe. It is also effective against seed rot fungi such as Aspergillus and Penicillium.

RANCONA CREST WR provides suppression of wireworm activity on seed and young seedlings.

Do not use RANCONA CREST WR in combination with other seed treatment products unless compatibility has been verified. Read and follow carefully all label directions of each combination product. When using combinations of products, the most restrictive of label limitations and precautions must be followed.


RANCONA CREST WR is formulated both for commercial and for on-farm application. DO NOT apply this product as a planter box or hopper box treatment. Apply RANCONA CREST WR with mechanical, slurry, or mist-type seed treating equipment, which has been calibrated to accurately and uniformly apply the product to seed. Uniform application to seed is necessary to ensure best disease and insect protection and optimum performance. For best activity of this product, seed must be sound and well-cured before treatment. Refer to the APPLICATION INSTRUCTIONS below for label rates.

In most cases, RANCONA CREST WR is ready to use and may be applied to seed as is; however, dilution with water may be appropriate for some types of treaters and/or when treating under dry and/or hot conditions, to achieve more uniform product to seed coverage. Mix RANCONA CREST WR and water thoroughly into a slurry prior to treating seed. Recalibrate treating equipment to compensate for the addition of water. The amount of dilution water that is most suitable depends on the seed, treater type and temperature. Contact your local company representative or supplier for specific recommendations.

- Do not use treated seed for food, feed or oil purposes.
- Care must be exercised in the handling of treated seed. Augers used for handling treated seed must not be used to move seed for feed, food or oil processing.
- Do not re-use bags from treated seed to handle food or feed products.
- Wheat, Barley, Oats, Rye, Triticale: Do not graze or feed livestock on treated areas for 45 days after planting.

Seed commercially treated with this product must be labeled in accordance with all applicable requirements of the Federal Seed Act. The user of this product is responsible for ensuring that the seed bag meets all requirements under the Federal Seed Act.

NOTIFICATION of the crop rotational restriction must be conveyed to the grower by appropriate seed tag labeling or bag printing on all seed units.

NOTE: If not already dyed, the purchaser of this product is responsible for ensuring that all seed treated with this product are adequately dyed with a suitable color to prevent its accidental use as food for man or feed for animals. Refer to 21 CFR, Part 2.25. Any dye or colorant added to treated seed must be cleared for use under 40 CFR, Part 153.155(a).

Federal regulations have established official tolerances for certain pesticide residues. In order that residues on food and forage crops will not exceed established tolerances, use only at specified rates.

The Federal Seed Act requires that bags containing pesticides treated seeds shall be labeled with the following statements:
- This seed has been treated with RANCONA CREST WR which contains imidacloprid, ipconazole and metalaxyl.
- DO NOT use treated seed for feed, food or oil purposes.

In addition, the U.S. Environmental Protection Agency requires the following statements on bags containing seeds treated with RANCONA CREST WR:
- Pollinator Precautions: Imidacloprid is highly toxic to bees. Ensure that planting equipment is functioning properly in accordance with manufacturer specifications to minimize seed coat abrasion during planting to reduce dust which can drift to blooming crops or weeds.
- Store away from feeds and foodstuffs.
- Wear long sleeved shirt, long pants, and chemical resistant gloves when handling treated seed.
- Treated seed must be planted into the soil at a depth greater than 1 inch.
- Exposed treated seed may be hazardous to birds. Cover or incorporate spilled treated seeds. Excess or leftover seed may be double sown around the headland or buried away from bodies of water in accordance with local requirements.
- Dispose of seed packaging in accordance with local requirements.
- DO NOT contaminate water bodies when disposing of planting equipment washwater
- DO NOT allow children, pets or livestock to have access to treated seed.
- In the event of a crop failure or harvest of a crop grown from RANCONA CREST WR treated seed, the field may be:

- Replanted immediately to barley, brassica (cole) leafy vegetables, canola, corn (field or sweet), cotton, cucurbits, leafy vegetables, legume vegetables (succulent or dried), mustard seed, oats, popcorn, potato, rapeseed, rye, safflower, sorghum, soybeans, sugarbeet, triticale, root and tuber vegetables, and wheat.
- For buckwheat and millet the minimum plant back interval is 30 days from the date RANCONA CREST WR treated seed was planted. ïï Cover crops for soil building or erosion control may be planted at any time but do not graze or harvest for food or feed. Exception: Wheat, Barley, Oats, Rye, and Triticale treated areas may be grazed on or feed to livestock 45 days after planting.
- For all other crops not listed on this product label or for crops for which no tolerance for the active ingredient has been established a 12 month plant back interval must be observed.

- The maximum application rate (including seed treatment foliar application and soil application) per acre per year for imidacloprid is 0.5 Ib.
- This seed has been treated with _____ Ibs imidacloprid per Ibs of seed [ or_____ mg imidacloprid per seed].
- Excess treated seed may be used for ethanol production only if (1) by products are not used for livestock feed and (2) no measurable residues of pesticides remain in the ethanol by products that are used in agronomic practice.

Treated areas may be replanted with any crop specified on this product label, or any crop for which a tolerance exists for the active ingredients, as soon as practical following the last application. The following plant-back intervals must be observed for listed crops:

Immediate Plant Back: Barley; Brassica (cole) leafy vegetables; Canola; Corn, Sweet; Corn, Field; Cotton; Cucurbits; Leafy vegetables; Legume vegetables (succulent or dried); Mustard Seed; Oats; Popcorn; Potato; Rapeseed; Root and Tuber Vegetables; Rye; Safflower; Sorghum; Soybeans; Sugarbeet; Triticale; Wheat

30-Day Plant-Back: Buckwheat, Millet

12-Month Plant Back: For all other crops not listed on this product label, or for crops for which no tolerance for the active ingredients in this product has been established, a 12-month plant-back interval must be observed.

Cover crops for soil building or erosion control may be planted any time, but do not graze or harvest for food or feed. Exception: Wheat, Barley, Oats, Rye, and Triticale treated areas may be grazed on or feed to livestock 45 days after planting.
