Phostrol Agricultural Fungicide: Phostrol is an important tool for managing key field and storage diseases of potatoes. If Phostrol is included in a foliar fungicide program, the harvested potatoes will be protected against infections from late blight and pink rot. Phostrol combined with chlorothalonil will protect vines from late blight as well. Extensive research has established Phostrol as the benchmark product for post-harvest control of late blight and pink rot. A post-harvest application also provides control of silver scurf.

Phostrol is a unique blend of sodium, potassium and ammonium phosphites. The pH neutral formulation mixes easily with other products. Phostrol controls diseases in two ways. It has direct activity on the disease organisms and will significantly reduce spore production. In addition, plant immune mechanisms are stimulated to produce substances that protect against disease infection. This complex mode of action makes Phostrol an outstanding component of fungicide programs targeted at managing disease resistance.

Ultra Flourish: The active ingredient in Ultra Flourish, mefenoxam, moves into the plant from soil or foliar applications. Its systemic mode of action prevents spore production, inhibits mycelial growth of the disease and improves crop health and vigor. Ultra Flourish actively controls Pythium spp. and Phytophthora erythroseptica. It can be applied in combination with liquid fertilizers or saturated into dry fertilizers.

Spirato 480 FS: New from Nufarm, Spirato seed piece treatment is the latest addition to its full line of products for potatoes. It contains a proven active ingredient, fludioxonil, to prevent early-season damage from decay, damping-off and seedling blight caused by seed-borne and soil-borne fungi. Spirato offers the same protection from fungal infections as the leading brand, but delivers a value only Nufarm can.

Agri Tin: Agri Tin provides proven performance against early blight and late blight. It is an important component of fungicide disease resistance programs designed to manage a broad spectrum of diseases by rotating products with different modes of action. Including Agri Tin in the fungicide program will have an added benefit in providing suppression of Colorado potato beetle populations. Agri Tin is available in 4 lb/gal flowable or 80 percent wettable powder formulations of triphenyltin hydroxide.

Nufarm T-Methyl: T-Methyl 4.5 F and T-Methyl 70 WSB contain thiophanate-methyl, which is especially effective at controlling white mold on potatoes, edible beans, canola and soybeans. Thiophanate-methyl will provide systemic curative control of existing disease and effectively protects new growth from subsequent infections.

Ranman: Ranman fungicide, a product of FMC Corporation, is a unique mode-of-action fungicide that provides excellent control of pink rot, late blight and tuber blight. A contact fungicide, Ranman is classified as a protectant with anti-sporulation activity and has limited systematic activity. Ranman provides growers with a much-needed novel mode-of-action for resistance management.

Rovral: Rovral fungicide, from FMC Corporation, stops fungi at several phases of development, including spore germination, mycelia growth and spore production. This multi-prong attack provides consistent, reliable disease prevention while reducing the risk of resistance development in future growing seasons. In potatoes, Rovral fungicide controls white mold and early blight with timely treatments to reduce profit-draining outbreaks.

T-22 HC: T-22 HC is a preventative, OMRI-listed biological fungicide for control of plant diseases. When applied to seeds, transplants or to soil or planting mixes, the active ingredient (Trichoderma harzianum strain T-22) grows onto plant roots as they develop and provides protection against plant root pathogens such as Pythium, Rhizoctonia, Fusarium, Cylindrocladium and Thielaviopsis. One application protects roots for up to 12 weeks, enhancing nutrient utilization and stress tolerance.

Manzate Pro-Stick: Manzate Pro-Stick is a standard preventative treatment for the control of early and late blight in potatoes. Through a patented manufacturing process, the unique formulation of Manzate Pro-Stick technology provides a more consistent delivery of the active ingredient to the treatment area. Small, uniform particles within the formulation break up faster to create a homogenous mixture that remains in suspension longer. Manzate Pro-Stick is distributed better to the leaf surface-allowing long-lasting disease control.

After decades of use, fungal strains have not developed resistance to multi-site Manzate Pro-Stick; an important factor when choosing your fungicide management program. Manzate Pro-Stick also offers users a wide window of application and tank-mix compatibility with other crop protection products. Manzate Pro-Stick belongs to the FRAC classification M3.
