PRODUCT INFORMATION
Mertect 340-F is a systemic fungicide which aids in the control of many important plant
diseases. If treatment is not effective following use of Mertect 340-F as recommended,
a tolerant strain of fungus may be present. Consideration should be given to prompt
use of other suitable non-benzimidazole fungicides. Mertect 340-F is not for use in
formulating agricultural products.
RESISTANCE MANAGEMENT
THIABENDAZOLE GROUP 1 FUNGICIDE
For resistance management, Mertect 340-F contains Thiabendazole, a Group 1
fungicide. Any fungal population may contain individuals naturally resistant to Mertect
340-F and other Group 1 fungicides. A gradual or total loss of pest control may occur
over time if these fungicides are used repeatedly in the same fields. Appropriate
resistance-management strategies should be followed. Thiabendazole belongs to the
methyl-benzimidazole carbamate class of chemistry which disrupts ß-tubuline assembly
in mitosis.
To delay fungicide resistance, take one or more of the following steps:
• Rotate the use of Mertect 340-F or other Group 1 fungicides within a growing season
sequence with different groups that control the same pathogens.
• Use tank mixtures with fungicides from a different group that are equally effective on
the target pest when such use is permitted. Use at least the minimum application
rate as labeled by the manufacturer.
• Adopt an integrated disease management program for fungicide use that includes
scouting, uses historical information related to pesticide use, and crop rotation, and
which considers host plant resistance, impact of environmental conditions on
disease development, disease thresholds, as well as cultural, biological and other
chemical control practices.
• Where possible, make use of predictive disease models to effectively time fungicide
applications. Note that using predictive models alone is not sufficient to manage
resistance.
• Monitor treated fungal populations for resistance development.
• Contact your local extension specialist or certified crop advisor for any additional
pesticide resistance-management and/or IPM recommendations for specific crops
and pathogens.
• For further information or to report suspected resistance contact Syngenta Crop
Protection at 1-866-796-4368. You can also contact your university extension
specialist to report resistance.

Do not apply within 12 hours prior to harvest.
Ornamental Bulbs and Corms (One Application Only) - Fusarium Basal Rot and
Penicillium Blue Mold: Clean and treat bulbs or corm within 24-48 hours of digging.
Prepare suspension of 30 fl oz of Mertect 340-F per 100 gal water. Submerge stock
completely in dipping suspension. Suspension temperature should be 55-75°F (13-
24°C). Discard suspension (1) when it becomes dirty, (2) after using five times, or (3)
after 24 hours, whichever occurs first.
Fusarium (Bulbs and Corms): Dip bulbs 15-30 minutes, corms 15 minutes.
Blue Mold (Bulbs): Dip 10-15 minutes.
After treatment, dry bulbs or corms in a shaded, well-ventilated area. Curing or
retarding may precede or follow treatment.
Potato - Fusarium Tuber Rot: Mist unwashed tubers on a conveyor line, with tumbling
action, entering storage with 0.42 fl oz of Mertect 340-F to each 2,000 lb of tubers in
sufficient water for complete coverage. If an additional treatment is necessary before
shipping, mist the tubers at the same rate or dip the tubers for 20 seconds in a solution
containing 0.42 fl oz of Mertect 340-F per gal of water. Do not treat seed potatoes after
cutting.
Mertect 340-F for potatoes should be used as part of an Integrated Management
Program, which includes prevention of bruising during harvest and maintaining proper
Mertect 340-F
Page 10
storage temperature and relative humidity. Neither cultural practices nor chemical
measures will prevent Fusarium infection if potatoes are damaged or improperly stored.
Pome Fruit Crop Group 11-10 (Apples and Pears) - Blue Mold Rot, Bulls Eye Rot,
and Gray Mold (Nest Rot, Cluster Rot), Stem End and Neck Rot: Dip, flood, or
spray harvested fruit with a suspension of 16 fl oz of Mertect 340-F in 100 gal of water.
Do not treat for over 3 minutes. Treat apples only before and after storage for
maximum decay control. Treat pears only once.
Sweet Potato Post Harvest Treatment Black Rot: Mist washed roots, on a
conveyor line with tumbling action, with 0.42 fl oz of Mertect 340-F in minimum of 0.5
gallons water per 2,000 lb of roots before packing. Ensure roots are dry before packing.
Mertect 340-F should be used as part of an Integrated Management Program that
includes prevention of wounding during harvest, and maintaining proper sanitation,
temperature, and humidity in storage.
Sweet Potato (One Application Only) “Seed Roots” - Black Rot, Scurf, and Foot
Rot: Dip the seed roots in a suspension containing 8 fl oz of Mertect 340-F per 7.5 gal
of water (107 fl oz per 100 gal). Treat the seed roots for 1-2 minutes and plant
immediately. Discard the suspension when the volume is too low or when it becomes
dirty. Do not use the treated roots for food or feed.
SEED TREATMENT
Treatment of highly mechanically scarred or damaged seed, or seed known to be of low
vigor and poor quality, except for the purpose of curative control of existing disease
pests, may result in reduced germination and/or reduction of seed and seedling vigor.
Treat using equipment similar to that planned for treating the total seed lot. Conduct
germination tests on a small portion of seed before committing the total seed lot to a
selected seed treatment. Due to seed quality and seed storage conditions beyond the
control of Syngenta, no claims are made to guarantee the germination of carry-over
seed or propagating material for all crop seed.
Seed treatment with Mertect 340-F provides protection from seed and soil-borne pests
listed under target diseases, thereby reducing the likelihood of encountering early-
season plant infection, or late-season disease symptoms resulting from early-season
infection.
For protection against other seed and soil-borne diseases not controlled by Mertect
340-F, it is highly recommended that a compatible seed treatment fungicide be used at
EPA registered label rates and tank mixed in combination with Mertect 340-F. These
fungicides must show safety on treated seed, alone or in combination with Mertect 340-
F. Consult the label for appropriate use rates and follow all use instructions.
Mertect 340-F
Page 11
MIXING PROCEDURES
Apply Mertect 340-F as a water-based slurry utilizing standard slurry seed treatment
equipment which provides uniform seed coverage. Uneven or incomplete seed
coverage may not give the desired level of disease control. Thoroughly mix the
recommended amount of Mertect 340-F into the required amount of water for the slurry
treater and dilution rate to be used. Follow the manufacturer application instructions for
the seed treatment equipment being used. Maintain constant agitation of the slurry
during the treatment.
• Use an EPA-approved dye or colorant that imparts an unnatural color to the seed as
required in 40 CFR 153.155 (c).
• Allow seed to dry before bagging.
Tank Mixtures
Confirm physical compatibility, seed safety, seed safety in stored seed, and biological
efficacy before tank mixing with other seed treatment products. Follow the label
directions for the most restrictive of label precautions and limitations. This product
cannot be mixed with any product containing a label prohibiting such mixing.
SEED CONTAINER LABEL REQUIREMENTS
The Federal Seed Act requires that containers oftreated seed must be labeled with the
following information:
• This seed has been treated with Thiabendazole fungicide.
• Do not use for feed, food, or oil purposes.
In addition, the following statements are required on containers of seeds treated with
Mertect 340-F:
• Store treated seed away from food and feedstuffs.
• Do not allow children, pets or livestock to have access to treated seeds.
• Wear long pants, long-sleeved shirt and protective gloves when handling treated
seed.
• Treated seeds exposed on soil surface may be hazardous to wildlife. Cover or
collect treated seeds spilled during loading and planting.
• Dispose of all excess treated seed by burying seed away from bodies of water.
• Do not contaminate bodies of water when disposing of planting equipment wash
water.
• This seed has been treated with X lb thiabendazole per 100 lb of seed.
• Regardless of type of application, do not apply more than 0.15 lb Thiabendazole
per acre (68.0 grams ai/A) per year
• Dispose of seed packaging or containers in accordance with local requirements.
