The use of graphite is recommended to promote seed flow,
provide lubrication for the seed meter and to help dissipate
static charge buildup. Among the available dry seed lubricants
graphite is the most effective and easiest to use and it requires no
mechanical agitation
CONVENTIONAL HOPPERS
Mix one tablespoon of
powdered graphite
with seed each time
hoppers are filled. Regular graphite use prolongs life of the seed
meter components, improves seed spacing, and may reduce buildup of seed treatments.
NOTE: DO NOT apply graphite only in center of hopper. It will filter too quickly through the seed and not
distribute as evenly as desired.
Apply graphite around outer perimeter of hopper.

15 ml/Hopper Fill
Talc
Conventional Hoppers
60
ml (
¼
Cup)*
*Double amount of talc for sunflowers.
NOTE: Additional graphite may be required to retard buildup of seed treatments on meter components. More
frequent cleaning of monitor seed tubes may be necessary due to use of additional graphite.
Talc seed lubricant
may be used as a drying agent in addition to graphite lubrication. The drying agent may improve
seed release and/or
to retard buildup of seed treatments on meter components.
1. Fill hopper
½
full of seed, add 60 ml (
¼
cup) (conventional) of talc and
mix thoroughly
.
2. Finish filling hopper, add another 60 ml (
¼
cup) (conventional) of talc and
mix thoroughly
.
3. Adjust rate of talc use as needed so all seeds are coated, while avoiding a buildup of talc in bottom of hopper.
Humid conditions and/or small sized seeds with extra seed treatment may require additional talc to maintain meter
performance.
NOTE: Liquid seed treatments or innoculants may create buildup on the seed disc or brushes. Check
frequently for proper population and/or seed delivery when using any liquid seed treatment.
Completely mix all treatments with seed following manufacturers’ recommendations. Seed treatment dumped on top of
seed after hopper is filled may not mix properly and cause seed bridging, reducing population or stopping meter from
planting.
