Diquat Landscape and Aquatic Herbicide is a very versatile contact killer. This is one of our main herbicides we use for most of our applications. Diquat is the main ingredient in Reward herbicide. It is very effective against a wide variety of submersed, emergent, and floating aquatic plants including duckweed, watermilfoil, and cattails!
Diquat is a very fast acting contact killer that is approved for use in and around the water! It does not stay active for very long, so it needs to be sprayed directly onto the vegetation. Diquat mixed with Cutrine Plus and a surfactant will kill pretty much any vegetation and algae that it is sprayed directly on. That is a great combination for treating areas with many different types of vegetation and algae!
Application Rates: How much Diquat do you need to apply?
Eurasian Watermilfoil- 1 gallon per acre
Duckweed- 2 gallons per acre of Duckweed
Cattails- 1 gallon per 20,000 square feet
Pond Weed- 1.5 gallons per acre
Shoreline Vegetation- 1 gallon per 20,000 square feet
Algae- Mix 8 ounces of Diquat with 1 gallon of Argos
Application Tips: How to apply Diquat?
Just simply mix 1 gallon of Diquat with 9 gallons of water and spray directly onto the vegetation. I recommend mixing in about 8 oz of surfactant and also some Cutrine Plus for best results. Since Diquat is a contact herbicide, it is best to apply it early on a sunny day when the plants are actively involved in photosynthesis. The biggest mistake people make is to come home from work and treat vegetation.
Water Use Restrictions:
Diquat is a very powerful herbicide that needs to be handled with caution and necessary safety equipment. Restrictions would be 1 day for livestock and fishing, 2-3 days for irrigation and swimming, and 5 days for irrigating food crops.
