Ecomazapyr 2 SL may ONLY be used for application to control undesirable emergent and floating aquatic vegetation in and around standing and flowing water, including estuarine and marine sites.
Ecomazapyr 2 SL may also be used to control undesirable vegetation growing in or around surface water in wetland, riparian and terrestrial habitats where applications may inadvertently contact surface water.
Ecomazapyr 2 SL may also be used for cut stump, cut stem and frill and girdle treatments within aquatic sites.
Ecomazapyr 2 SL is an aqueous solution intended to be mixed with water and surfactant(s) for application to control floating and emergent undesirable vegetation (see AQUATIC WEEDS CONTROLLED BY ECOMAZAPYR 2 SL section and the ADDITONAL WEEDS CONTROLLED BY ECOMAZAPYR 2 SL section) in or near bodies of water which may be flowing, non-flowing or transient.
Ecomazapyr 2 SL may be applied to aquatic sites that include lakes, rivers, streams, ponds, seeps, drainage ditches, canals, reservoirs, swamps, bogs, marshes, estuaries, bays, brackish water, transitional areas between terrestrial and aquatic sites and seasonal wet areas. See AQUATIC USES, PRECAUTIONS AND
RESTRICTIONS section of this label for precautions, restrictions, and instructions on aquatic uses.
Ecomazapyr 2 SL may also be used for cut stump, cut stem and frill and girdle treatments within aquatic sites (see AERIAL APPLICATIONS AND GROUND APPLICATIONS sections for additional details). Read and observe the following directions if aquatic sites are present in terrestrial non-crop areas and are part of the intended treatment area: Ecomazapyr 2 SL controls most annual and perennial grasses, broadleaf weeds and many brush and vine species. Ecomazapyr 2 SL will provide some residual control of undesirable species that germinate above the waterline. Ecomazapyr 2 SL controls vegetation by absorbtion through emergent leaves and stems, from which it is translocated throughout the plant, where it accumulates in rapidly-growing meristematic tissue.Treated plants stop growing soon after treatment. Chlorosis (yellowing of plant tissue) first appears in the newest leaves, and necrosis spreads from this point. In perennials, Ecomazapyr 2 SL is translocated into and kills underground or submerged storage organs to prevent regrowth. Chlorosis and tissue necrosis may not be apparent in some plant species until two or more weeks after application. Complete kill of plants may not occur for several weeks. Applications of Ecomazapyr 2 SL are rainfast within one hour after treatment. Ecomazapyr 2 SL will not control plants which are completely submerged or have a majority or their foliage under water.
Ecomazapyr 2 SL must be applied to the emergent foliage of the target vegetation, since it has little-to-no activity on submerged vegetation. Residual concentrations of Ecomazapyr 2 SL from direct application to water are not expected to be sufficient to provide control of undesirable vegetation.
Apply Ecomazapyr 2 SL so as to maximize spray contact onto the target vegetation while minimizing overspray onto adjacent or underlying water. For optimum performance, include a surfactant (see ADJUVANTS section for specific recommendations) in the spray solution and apply to actively growing weeds. Ecomazapyr 2 SL may be applied in spot treatments by using low-volume directed application techniques or broadcast by using ground equipment, water craft or helicopter.
Apply Ecomazapyr 2 SL with surface or helicopter application equipment in at least 5 gallons of water per acre. When applying by helicopter, follow directions under the AERIAL
APPLICATIONS section of this label, otherwise refer to section on GROUND APPLICATIONS when using surface equipment.
Applications to moving bodies of water should be made while traveling upstream to prevent concentration of this herbicide in water. DO NOT apply to bodies of water or portions of bodies of water where emergent and/or floating weeds do not exist.
