Hamer’s model 600NW RIB Gravity Feed secondary vibratory feed meets EPA insect resistance management (IRM) program requirements for bagged and boxed packaged seed. This technology allows growers to end the need for separate refuge areas on their farms, making planting easier. Now, bags of seed contain both insect resistant traited and untraited seeds mixed together. Available in both simplex and duplex versions, the 600NW RIB is the most accurate and cost effective system available. Plus, weighment data is transmitted and collected to meet EPA and trace provider compliance.
