We are discussing two different products used for two different issues. If we were spraying one of our 46 mosquito control ditches - he was spraying a herbicide for control of vegetation in the ditch to keep water flowing. If the ditches are allowed to become overgrown with vegetation the plants catch debris floating in the water and cause the formation of pools.
Aerial spraying is utilized to disperse a adulticide which is not supposed to be dispersed over lakes and streams without water quality testing to monitor potential damage to aquatic life. Spraying by truck allows for a more selective application within proximity to water.
For vegetation we utilize the product described below.
Glyfos Aquatic brand of glyphosate is a broad spectrum, non-selective, post-emergent herbicide for use in aquatic and other non-crop sites. Applied to actively growing partially or fully emerged plants prior to seed head formation, Glyfos Aquatic provides effective control of more than 190 species of herbaceous and woody plants.
Glyfos Aquatic is one of the few herbicides available for use in highly sensitive, protected areas such as habitat restoration sites and protected wetlands including the Everglades. Glyfos Aquatic can also be used in non-crop aquatic sites such as golf courses, parks, retention ponds and wastewater treatment facilities.
