For large quantities, like adding talc to central-fill planters, our products can be applied by scoop, shovel, or any means available. For more precise metering of products including graphite or 80/20 Premium Blend, we recommend the Enviropac Seed Treater. You may contact the company directly at 800/752-1414, www.enviropacinc.com. All TalcFarm products are guaranteed to apply as easily as OEM seed lubricants, and at big savings!
