Alligare® Diquat Herbicide is a contact herbicide used to control aquatic weeds in public waters such as ponds, lakes, reservoirs, marshes, bayous, drainage ditches, canals, streams, rivers, and other slow-moving or quiescent bodies of water.

Alligare® Diquat Herbicide contains 37.3% Diquat Dibromide 

Begins to Work on Contact for No-Wait Control

Alligare® Diquat Herbicide is a contact herbicide rapidly absorbed by target plants within minutes of application. Alligare® Diquat Herbicide also rapidly kills undesirable above-ground weed growth in 24 to 36 hours. Avoid application to desirable plants. It is essential to obtain complete coverage of the target weeds to get control.

For very dense submersed aquatic plant populations, resistant species and certain types of algae, it is manufacture recommended to use Alligare® Diquat Aquatic Herbicide in combination with an approved tank-mix partner. Approved tank mix partners include: Clearigate, K-Tea, Komeen, Cutrine Plus, Aquathol K and Hydrothol 191.

Application

Alligare® Diquat Herbicide is effective anytime it is applied to live foliage that is reasonably developed, but before growth becomes too dense or weeds flower. Application rates vary; refer to the label for the target plant dosage rates required. Mix the required amount of Alligare® Diquat Herbicide with pond water according to label instructions preferably on a sunny day. When exposed to light, Alligare® Diquat Herbicide becomes activated and kills the weed. For difficult to control weeds the addition of Cutrine Plus® can boost effectiveness. Under low light conditions, Alligare® Diquat Herbicide may translocate to other weed parts from the point of contact.

Use of a non-ionic surfactant such as Cygnet Plus will increase the penetration of the product throughout the entire plant for better results.

Once completely dead, use a rake, such as the Weed Raker, to remove dead weeds. Apply Bio Boost Muck Digesting Pellets post treatment to digest dead plant material and consume organic muck.

To apply, determine the volume of water to be treated. Dilute with a minimum of 9 parts water. Spray uniformly over the water surface with a tank or backpack sprayer. Allow material to rain down in coarse droplets for better surface penetration.

For Best Results

Begin application in spring as water temperature warms to 50º F and above. Heavy, out of control growth may require more than one application or physical removal to gain control. For best results, use under conditions of minimal water flow. Apply early on the morning of a calm, sunny day when the plants are actively involved in photosynthesis. The biggest mistake people make is to come home from work and treat vegetation. Contact time should be at least 3 hours.

Turbid water or mud-covered foliage will reduce absorption and effectiveness.

For algae control best results are achieved when mixing Reward® is combination with Cygnet Plus, Cutrine Plus and Bio Boost Enzyme 300. Dose requirements are less for Duckweed control or shallow waters of less than 2 Feet. For Duckweed control the label recommends adding a non-ionic surfactant. One quart of Cygnet Plus Surfactant is typically enough for most projects. Add Bio Boost Enzyme to the Tank Mix to increase the effectiveness of the algae treatment. Treat heavy infestations in sections to avoid oxygen depletion.
