Use of Talc Lubricant

causym CAUTION: Follow chemical manufacturers precautions when handling parts coated with seed treatments. Use proper skin, eye, and respiratory protection.

Talc lubricant is required for optimum performance of the vacuum meter and CCS system (if equipped). Seed properly treated with talc releases from the seed disk more consistently, leading to more accurate spacing when the seed is placed in the ground.

FARMER APPLIED SEED TREATMENT
For best performance, use of farmer-applied seed treatments is not recommended. If used, apply any seed treatment to seed and allow to fully dry before placing in tanks.

Apply seed treatment to seed BEFORE applying talc lubricant to insure that treatment adheres to seed properly while minimizing buildup on meter components. If buildup of treatment still occurs, contact the chemical manufacturer for assistance.

When using seed treatments, clean meters and seed disks as needed. Seed disks can be cleaned with warm, soapy water. Spray graphite on vacuum seal side of disk as needed.

IMPORTANT: If farmer-applied treatments are used, follow chemical manufacturers recommendations carefully. HIGH-OIL-CONTENT TREATMENTS ARE NOT RECOMMENDED.

Chemical reaction between farmer-applied seed treatments and treatments commercially applied to seed can cause seed treatments to become sticky. Certain temperature and humidity levels can further complicate material compatibility.

Mixes of seed and seed treatment must be free of clumps.

IMPORTANT: Talc has to be thoroughly incorporated in tanks and hoppers, so all seeds are evenly coated.

COMMERCIALLY TREATED SEED

Refer to the following talc application rate charts for planting commercially treated seeds with no farmer-applied seed treatments.

Some insecticide-treated seed is coated with commercially applied talc. Even if talc is commercially applied, the required amount of talc shown in the following tables must be added to maintain metering performance.

Use this table when using 1.6 or 3.0 bushel hoppers (without CCS tanks) to deliver seed to seed meters:

MaxEmerge™ Hopper Talc Application Rate
Note: Talc must be sprinkled over top of seeds in hoppers and thoroughly incorporated, so all seeds have talc coating.
Hopper Size Amount of Talc
58 L (1.6 bu.) 120 mL (1/2 cup)
106 L (3 bu.) 240 mL (1 cup)

 

Adjust these rates as necessary so all seeds become coated with talc, while avoiding an accumulation of talc in bottom of tank.

Double the talc recommendation when planting small seed, large seed, seeds with heavy treatment, or humid planting conditions.

In certain situations, combinations of sticky seed treatments, large or small seed, and high humidity, it can be necessary to add up to two to three times the amount of talc shown in the tables.

IMPORTANT: It is necessary to clean any buildup of seed treatments and talc out of hoppers between fills.

If talc builds up in bottom of hopper and vacuum manifolds require frequent cleanout, reduce talc rate accordingly. If a coating of seed treatment is found on seed disks, increase the amount of talc.
