The Minnesota seed-grain treater
1938
Moore, M. B. (Matthew B.)
Ever since chemical dust disinfectants came into use for treating the seed of small grains and corn to control smuts and certain other diseases, there has been a need for a suitable treating machine to mix the dust with the seed. The right kind of treater must not only do a thorough job but also must be simple and inexpensive to make and easy to use. The plans in this circular will enable anyone handy with tools to make such a treater in a very short time.
