Seed Treatment Equipment

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, pro¬vided that the equipment can be 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 ap¬propriate 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 Chemtura representative or supplier for specific recommendations.
