Results of recent field trials using the chelated copper formulation
Clearigate®
4
showed that applying a 20% solution
by volume was effective for controlling populations of giant
salvinia in irrigation canals.

Lower rates may be efficacious,
thereby reducing chemical use and cost; however, little is
known about the dose-response effects of Clearigate®
against giant salvinia. The objective of this study was to determine
the effective rate range of chelated copper applied as
Clearigate® for control of giant salvinia
