When should I use Harvester Herbicide?

Treat with Harvester when weeds are actively growing. Treating actively growing submerged weeds allows the aquatic herbicide to be absorbed by the plant, where it travels to the root system, and kills the entire plant.

When is the best time to treat with diquat herbicide?

For best results, treat early on a sunny day. This allows for maximum absorption of herbicide into the pond weed.

Treatment instructions for Harvester:

Mix in a tank sprayer. Apply treatment directly to aquatic weed growth via sprayer. 3 gallon Sprayer sold here

Only treat one half of pond every 14 days. When treating for weeds in deeper water, place spray nozzle under water. Any pond weeds missed with first application should be retreated 2 weeks after the initial Harvester Application. Dense weed populations often require follow-up application.
