Research Project: Examining Plant Growth Regulator (PGR) and Herbicial Activity on Container-Grown Crops Produces in Alternative Soilless Substrates

Location: Southern Horticultural Research

Project Number: 6062-21430-002-03-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Sep 1, 2012
End Date: Aug 31, 2017

The objective of this cooperative research is to characterize and fully measure the efficacy of certain herbicides and plant growth regulators applied to crops grown in various soilless substrates.

Different rates of herbicides and plant growth regulators (PGRs) will be applied to container-grown plants produced in various soilless substrates. Using a nutrient recovery system, the effluent and/or substrate at various depths will be collected and analyzed to determine the rate of leaching. In addition, applied radio-labeled herbicides will be analyzed to determine efficacy in these alternative substrates, especially in the root zone.
