No dewberries but I kill everything that is wood or woody stemmed with Remedy. This includes trees, briars, poison ivy, blackberries, etc.

This year "hot and dry" has obliterated most of that stuff.

You might have to spray some stuff like oaks several times. Or mix 3:1 with diesel and spray trunks. I have found that all woody stemmed plants can be very tenacious of life.

I don't remember what surfactant I used but it made a huge difference when used as a foliar.

It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.

Boy, if I say "sic em", you'd better look for something to bite. Sam Shelley Rancher and Farmer Muleshoe Texas 1892-1985 RIP Grandpa
