Benefits of Assist Red Dye

Highly visual spray marker dye.

Visible for up to 10 days post application.

Assist Red Dye allows the spray operator to identify sprayed plants and areas for up to 10 days following application. This saves re-treatment, chemical wastage and labour. While spraying it shows the operator exactly what coverage they have on the target plant.

Mixing and compatibility

Add Assist Red Dye to water in the spray tank first, agitate or mix thoroughly before adding any other product.

Under most circumstances Assist Red Dye is compatible with most pesticides including phenoxy based products and brush weed herbicides.

Several factors can affect this compatibility and therefore it is recommended to do a jar test prior to using products with alkaline chemistry such as Pasture Guard MCPA and Pasture Guard MCPB.
