Cygnet Plus Activator is a liquid additive for use along with liquid herbicides and algaecides to enhance their effectiveness. The surfactant in these non-ionic, water soluble and biodegradable products eliminates beading, providing a uniform spray solution. This ensures maximum contact with the plants' foliage. The low viscosity oil in these products breaks down the waxy coating on leaf surfaces for improved penetration and coverage. Use three ounces per gallon of water.
