I have seen your enthusiasm over Fluridone for sometime and am sure it is a very effective treatment for EWM. Our ponds have streams flowing through them with constant turnover of the water and when I looked at Sonar I became stumped at how it could be applied in our situation. Do you have a solution to the flowing water problem? I started using the diquat/ Cutrine+ method many years ago when, to the best of my knowledge, choices for EWM were 2-4D pellets and diquat. I chose the diquat treatment because these ponds are fished constantly and shutting them down for a lenghty period is undesireable and the stream is used for irrigation on a ranch below our ponds with the possibility of the herbicide being carried downstream is also undesirable. Is Sonar a long term systemic herbicide and can it be used with the restrictions I have mentioned?

Thanks for your reply.

If you don't care where you are you ain't lost. OMB
