“Plant growth won’t always hinder the use of a pond,” George Selden, University of Arkansas at Pine Bluff Extension fisheries specialist, said. “But if there are problematic weeds and they are not monitored and stopped, they can grow thick so quickly that it may become impossible to launch a boat, swim or fish.”
Aquatic weeds are especially a problem in older ponds, Selden said, and many Arkansas ponds were built long ago.
“Controlling weeds early in the spring is important for several reasons,” Selden said. “If weed infestations can be caught when small, control is easier and cheaper. Also, dissolved oxygen problems can result if herbicides are used to control weeds during the summer, so treatment needs to occur before the water gets hot.”
Effective control measures vary widely among different types of weeds, and weed control begins with correct plant identification.
