Reward Landscape and Aquatic Herbicide is a highly concentrated formulation of Diquat and is a very versatile contact killer. This is one of our main herbicides we use for most of our applications. Reward is very effective against a wide variety of submersed, emergent, and floating aquatic plants including duckweed, watermilfoil, and cattails!

Reward 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. Reward 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 Reward 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 Reward with 1 gallon of Cutrine Plus

Application Tips: How to apply Reward?

Just simply mix 1 gallon of Reward 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 Reward 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:

Reward 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.
