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).
Mix at a ratio of 0.035 oz (1 gram) of Heads Up® Plant Protectant per 34 ounces (1 liter) of water.
34 ounces (one liter) of this solution will treat 220-582 lbs (100 – 264 kg) of potato seeds.
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.
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.
