Effect of Glyphosate Rate and Spray Volume on Control of Giant Salvinia

Giant salvinia (Salvinia molesta (D. S. Mitchell)) is a free-floating, aquatic fern native to Brazil that has established andbecome a nuisance in many lakes, rivers, irrigation canals, and reservoirs of the United States (Jacono 1999, Jacono and Pitman 2001, McFarland et al. 2004). Outside its nativ...

Description
Summary:Giant salvinia (Salvinia molesta (D. S. Mitchell)) is a free-floating, aquatic fern native to Brazil that has established andbecome a nuisance in many lakes, rivers, irrigation canals, and reservoirs of the United States (Jacono 1999, Jacono and Pitman 2001, McFarland et al. 2004). Outside its native range, giant salvinia is considered one of the world's worst weeds due to its prolific growth habit, effective means of dispersal, tolerance to adverse growing conditions, and difficulty of control (Oliver 1993, Jacono and Pitman 2001, McFarland et al. 2004). Heavy infestations not only limit humanuse of water resources (fishing, boating, irrigation) but can alsonegatively impact the ecology of aquatic systems by restricting light penetration, degrading water quality (decreased dissolved oxygen andpH), and reducing valuable native plant and animal habitat and biodiversity (Thomas and Room 1986, Oliver 1993, McFarland et al. 2004).
