DMA4 Thumb
Product Label SDS Sheet

With its versatile label, DMA 4 IVM authorizes vegetation managers to treat many places that other labels don't allow. DMA 4 IVM is a 2,4-D product labeled for application to emerged, submerged or floating aquatic vegetation, including weeds and brush in standing water or on banks and shores of these aquatic sites.

Controls Eurasian Water Milfoil

DMA*4 IVM provides general aquatic weed control for susceptible emergent species, primarily broad-leaved plants and also controls brush and bulrushes.

How it Works

DMA-4 selectively controls dicot weeds including some of the most troublesome, such as water milfoil and coontail. Absorption is mainly through the leaves and it accumulates in growth tissues and causes abnormal growth responses.

Use of a non-ionic surfactant such as Cygnet Plus is highly recommended.

Begin application in spring as water temperature warms to 55º F and above. Early treatment when growth first appears or begins.

Heavy, out of control growth may require more than one application or physical removal to gain control. Apply early on the morning of a calm, sunny day. Several hours of contact time is needed.
