Diquat SPC 2L with diquat dibromide (37.3%) is a non-selective herbicide that provides fast control on tough aquatic weeds on contact. It provides broad-spectrum control as it spreads quickly through the water for floating, submersed, and marginal weeds. Diquat SPC 2L is applied to the foliar leaves, and moves slightly through the plant tissue. Using a surfactant will enhance activity. As it reaches any soil, it is completely inactivated.

It is safe around fish, wildlife and other organisms with no concerns abut groundwater problems.

Optimum Control

Apply Diquat SPC 2L to submersed weeds when weeds are actively growing and water temperatures are 50°F or more for optimal control.

Do not apply when weeds are growing under stress.
