Restrictions
Do not use treated seed for food, feed or oil processing.
Environmental Precautions
Ensure proper soil incorporation of the seeds. Do not feed treated seed to, or otherwise expose to wildlife or domestic
birds. Ensure proper disposal of any surplus treated seed not intended for later planting. Do not contaminate water
supplies or any body of water with the chemical contained in this seed treatment. Do not contaminate water by
cleaning of equipment or disposal of wastes. Unused or leftover treated seed should not be stored where there is a
chance of it becoming mixed with untreated seed.
Leaching
:
The use of this chemical may result in contamination of groundwater particularly in areas where soils are
permeable (e.g. sandy soil) and/or the depth to the water table is shallow.

Application Information
Commercial treaters and on-farm auger treating
:
Crown is added directly to the seed as it enters a mixing
chamber or auger. When a grain auger is used for treating, running the auger less than full is the key to adequate
mixing.
Application to seed in a hopper box or seed drill
:
Partially fill the hopper box or seed drill with a pre-measured
amount of seed. Apply the proper amount of Crown evenly over the surface of the seed. Mix with a paddle until all
seed is of a uniform red colour, indicating adequate coverage. Repeat this procedure until the hopper box or seed drill
is filled. Seed can be planted immediately after treatment without drying.
Seed treatment and inoculum sticker
:
Crown’s liquid properties enable this product to perform as a sticker for
inoculants. Partially fill the hopper box or seed drill with a pre-measured amount of seed. Apply the proper amount
of Crown evenly over the surface of the seed. Read inoculum label before use. Apply the recommended amount of
inoculum evenly over the treated seed and mix thoroughly. Repeat this procedure until the hopper box or seed drill
is filled. Seed treated with Crown will remain damp for a period of time following treatment. This enables inoculant
added to the hopper box or seed drill to adhere uniformly to seed, thus ensuring adequate nodulation of lentil and
chickpea seedlings.
