Heads Up® Plant protectant is a preplant seed treatment for the prevention of fungal and bacterial diseases in potato including black scurf and rhizoctonia canker (Rhizoctonia solani).

Application Rate

When Heads Up® is applied with other commercial seed treatments, first make a solution of 1 liter of water to one 58 gram package. Shake well, Heads Up® will dissolve uniformly and easily. One liter (34 oz.) of solution will treat up 220-582 lbs (100-264 kgs) of potato seed.


For seed potatoes, whether fresh cut or suberized, the Heads Up® solution must be applied to germinating seed potatoes, as indicated by obvious sprouting activity coming from the potato eyes.

Special Considerations

One 58 gram package of Heads Up® is intended to treat up to 25 tonne (55,000 lbs) of seed when applied with fine mist nozels.


It is important to get the seed potatoes to have good coverage and a shiny wet appearance from the solution. Providing thorough coverage is received, product will dry quickly and then potato seed can be planted when ready.

Treat only healthy vigorous seed or seedlings: Application of Heads Up® Plant Protectant to damaged or diseased seed or seed of low quality or vigor will not improve seed performance. Always apply to healthy seed or seedlings that are vigorous and actively growing under stress-free conditions.
