Soils Lab scientist Frank Forcella and Jim Eklund (on ATV) test the concept of sandblasting weed seedlings for selective control in corn. In place of sand, the grit was comprised of dried corn cobs ground to pass through a 20-40 mesh sieve. The gerry-rigged system is meant to simulate an imagined implement that would treat multiple rows simultaneously through pairs of nozzles aimed at the base of either side of each crop row.
