Herbicide Control of Water Shield

Herbicide control is a great option for Water Shield because you can literally apply the herbicide and then sit back and let it do its work. Most herbicides can control Water Shield throughout the season and only needs to be applied once a year.

Herbicide Products To Control Water Shield

Rodeo Herbicide-          Rodeo Herbicide + Adjuvant

Rodeo herbicide plus adjuvant is the best herbicide control for Water Shield because it is extremely effective at killing it at its roots and preventing it from coming back for years. Its active ingredient is Glyphosate† N-(phosphonomethyl) glycine, isopropylamine salt which has shown to be practically not-toxic to freshwater invertebrates.  The Adjuvant helps speed up the process of effectiveness of Rodeo herbicide to produce even better results.

After applying Rodeo herbicide you should start to see results within 2 to 4 days and within 7 to 10 days your Water Shield problem should disappear. However, you want to make sure there is no rain in sight for 6 hours after applying for maximum results.

Navigate Granular Aquatic Herbicide-          Navigate Granular 

Navigate Granular is formulated on special heat treated attaclay granules that resist rapid decomposition in water. They quickly sink to your lake or pond bottom and release 2,4-D into the critical root zone.

Initial effects are indicated by brittle stems and curling leaf tips and are noticeable within 7 to 10 days. A full kill will occur within 3 to 5 weeks.
