I am not a big fan of chemicals and will go to extremes to avoid using them. Having looked at numerous other chemicals Sonar seemed to be the safest.There is no doubt that the cost will collect your attention. I believe it is a cost vs. benefit analysis. The reasons stated below made the cost worth it for me.
1.)The restrictions on Sonar are extremely minimal.
2.)Sonar is extremely friendly to the environment and to humans.
3.)Application is very easy.
4.)There are virtually zero negative effects to the pond.
5.)You can call Sepro and someone(a live person)answers the phone.
I personally believe it is the closest thing, depending on your parameters, to a silver bullet for Hydrilla.
Before anyone asks,no I do not sell, represent or market for Sepro. Just a guy battling Hydrilla!!
