The ranch owner has a roughly 50,000gallon pond that has this blade shapped water plant I believe to be water hawthorn... similiar to this :



I believe he used copper sulphate to the exposed leaves at the water's surface,.. only to kill the lives but not the plants.

What can i suggest he use to NUKE the pond of water plants,.. but not harm the perch in there ?

thanks !
