dc.description.abstractUse of pesticides in aquatic environments is quite restricted because of the use of these areas for irrigation, recreation, and domestic water supplies. It is important that chemicals used in these areas be applied strictly in accordance with label directions. MOST AQUATIC HERBICIDES WILL BE MORE EFFECTIVE IF APPLIED WHEN WEEDS FIRST BEGIM ACTIVE GROWTH. THIS SHOULD BE CHECKED BY SA~PLIHG THE LAKE BOTTOM IN THE LATE SPRING OR EARLY SOMMER IM AREAS HEAVILY INFESTED THE YEA~ BEFORE. TREATMENT OF DENSE WEED GROWTH CAN RESULT IN LOSS OF FISH. DURING THE DECOMPOSITION OF THE DEAD PLANTS, OXYGEN DEPLETION CAN OCCUR AND THIS CAN CAUSE FISH KILL. Recommendations for aquatic areas are based on rate per surface areas, rate per acre foot, or parts per million (ppm) • In this particular case, rate per acre foot was chosen rather than ppm. If label directions are given in ppm, they may be used in accordance with the instructions on the label. An acre foot is 1 acre of water 1 foot deep. For a pond with a gradual slope acre feet may be determined approximately by multiplying 1/2 the depth at the deepest point, times the surface area. A pond with 1 surface acre and a gradual slope to 10 feet depth at the deepest point would contain approximately 5 acre feet of water.en
