Applications of Diquat Herbicide have proven to work best against Hydrilla and will kill growths quickly. It can reproduce four ways: Fragmentation, Tubers, Turions, and Seeds (primary reproduction of Hydrilla is vegetatively with seeds being a minor means of reproduction). Survey your lake or pond and determine what the best and safest plan of option there is to take. Floating weedsare those that float on the pond surface. Hydrilla outbreaks can deal a lot of damage to the economy. Grass carp will seldom control aquatic vegetation the first year they are stocked. Eradication of Hydrilla can be very difficult to achieve once a population is established. Hydrilla can reproduce via fragmentation, from seeds, from turions (also known as axillary buds), and from tubers. For easy hydrilla control, we recommend using our Dock and Swim Area Products. Hydrilla can tolerate lower temperatures and lower levels of sunlight than some native species. Due to its ability to spread rapidly and completely clog waterways, hydrilla poses significant threats to the aquatic ecosystem and recreational resources. ; Leaves grow in whorls of 3-10 along the stem; 5 is most common. This invasive, non-native is rapidly moving north from present infestations in California, Arizona, Gulf Coast; and from Southeast states north to Washington D.C. A wide variety of environmental conditions within flowing, stagnant, fresh, tidal, subtropical and temperate areas contain habitat suitable for Hydrilla. Hydrilla was first discovered in 2008 in a small pond in Orange County and has since been discovered in Broome, Cayuga, Erie, Kings, Monroe, Nassau, Niagara, Suffolk, Tioga,Tompkins, and Westchester counties. This plant is known as the “invisible menace” because most of the time they go undetected until they have filled the water. Unfortunately once hydrilla infests a water body, it is difficult and very costly to eradicate. This can allow Hydrilla to establish itself sooner, out-competing and displacing native aquatic plants. Our Dock & Swim Area Products or Hydrothol Granular provide excellent control on Milfoil. It'll be better and less labor-intensive to just apply a strong herbicide like Diquat to kill off all that growth. This is a non-native plant that should not be grown as it is invasive and illegal to possess or transport this species in Texas. We can remove the first video in the list to add this one. It grows on the bottom of the pond and floats on the water. These include algae, floating weeds, submerged weeds and emergent weeds. If you are dealing with Hydrilla on your property, this step-by-step DIY guide can help you in the form of effective aquatic herbicides and helpful how-to advice. Treatment Step 1 - Prepare and Mix the Diquat. Optimum results may be achieved by applying our Dock and Swim Area Products. Hydrilla is found in light conditions as low as 1% of sunlight and depths of only a few inches to 50 feet. Hydrilla Control. While a few of these aren’t always a bad thing, keeping them under control is important to ensure that they don’t overtake your pond, limit sunlight, or use up vital dissolved oxygen in the water.

For use in ponds, lakes, reservoirs, bayous, drainage ditches, non-irrigation canals, rivers and streams that are quiescent or slow moving. Try to cut as much of the plant free as you can as even small parts of the plant left in the water will grow back quickly. Hydrilla can also reproduce by potato-like tubers 1/2" long by 1/2" broad attached to the creeping root-like stem or rhizome found 30 cm deep in the mud. The dense foliage of Hydrilla can form mats that intercept sunlight, thereby displacing native aquatic plants. You will see the plant in large numbers bunched together on the surface of the water. Herbicide Control of Hydrilla. Reapplication may be necessary 21 days after the initial application is complete. Copper Sulfate and Diquat (Reward) Mixed to the highest label rate can control it or suppress over grown Hydrilla. It’s also high in B-12 and iron. These plants don’t have roots and move freely around the pond with the wind. The plants extend their roots twenty feet into the water, and any bit of Hydrilla that breaks off can form an entirely new plant. Biocontrol efforts have been extremely successful due to the introduction of a small fly native to Pakistan. 1.
