Abstract
This study was to explore fluid drilling gels as carriers for activated carbon.
The purpose of the carbon was to increase herbicide tolerance in direct seeded lettuce grown on organic soils.
In greenhouse studies, it was found that ‘Natrosol 250 HHW’ gel had the greatest mobility in soil compared to ‘Laponite 445’ and ‘Viterra II’. The least crop injury resulted when carbon was incorporated into Natrosol gel compared to other gel types.
Field studies were conducted in 1982 and 1983. Only data from 1983 is presented.
Pelleted, fluid drilled and carbon incorporated fluid drilled seeds were sown and atrazine, chloramben and diuron were applied preemergence.
Fluid drilled seeds with and without carbon resulted in less crop injury than pelleted seeds.
Addition of ‘Gro-Safe’ to the gel further decreased crop injury compared to conventional fluid drilling or pelleting.
