Per the General Use Info on the Catt Plex product label: This product moves through the plant from the point of foliage contact to and into the root system. Visible effects on most annual weeds occur within 2 to 4 days but on most perennial brush species may not occur for 7 days or more. Extremely cool or cloudy weather following treatment may slow the activity of this product and delay visual effects of control. Visible effects are a gradual wilting and yellowing of the plant that advances to complete browning of aboveground growth and deterioration of underground plant parts.
This product will not prevent new growth in the soil or water so you would need to reapply as new plants come up, however it will completely kill a plant you spray it directly on.
Surfactants are "sticking agents" that help herbicides stick to the target weeds. Using a surfactant will help with better coverage and faster burndown. The Catt Plex label recommends using a non-ionic surfactant such as Southern Ag Non-Ionic Surfactant.
Catt Plex should be sprayed as a broadcast or spot treatment for aquatic weeds in accordance with the product label. Catt Plex will not control submerged weeds; you will usually need a differenct active ingredient for submerged weeds. If you have identified the specific plants that you are targeting, then we would be happy to make a recommendation for you.
The manufacturer recommends using a non-ionic surfactant with Catt Plex, rather than dishwashing liquid. You can find dilution rates beginning on page 9 of the product label.
Catt Plex is a post-emergent herbicide, so you can use it any time the target weeds are actively growing. Post-emergent herbicides like this one containing glyphosate will not work well if the plants are not growing, so if the plants have stopped growing, then you may consider physically cutting them down and then applying if/when you see regrowth.

The aquatic weed control products that we carry are not labeled for tidal area applications except Cattplex as it is a glyphosate herbicide labeled for eradicating beach grass. Schedule applications in order to allow 6 hours before treated plants are covered by tidewater. Rainfall or immersion within 6 hours after application may reduce effectiveness.

Catt Plex must be used as directed with a surfactant for best results on targeted weeds.
Catt Plex is not labeled for duckweed. The Diquat Water Weed and Landscape Herbicide is labeled for duckweed control and will do a good job. For duckweed control, apply Diquat Water Weed and Landscape Herbicide at 1-2 gallons/A + 32 oz./A of surfactant in at least 100 gallons of water. Treatment of dense weed areas may result in oxygen loss from decomposition of dead weeds. This loss of oxygen may cause fish suffocation. Therefore, treat only 1/3 to ½ of the water body area at one time and wait 14 days between treatments.
Catt Plex is labeled to target Reed Canarygrass and Giant Reed. Pleaser refer to the product label for specific application instructions and use as directed.
