General Information


RANCONA 3.8 FS is a systemic broad-spectrum fungicide and seed dressing specifically for protection against soilborne and seedborne disease of crop plants. RANCONA 3.8 FS is active against Rhizoctonia, Fusarium, Cochliobolis sativus, Diaporthe, and Phomopsis as well as against smuts and bunts in cereals (see crop for specific diseases). In addition, RANCONA 3.8 FS provides activity against weakly pathogenic fungi such as Mucor, Rhizopus, Aspergillus, Penicillium, Alternaria, Sclerotinia, Botrytis, and Cladosporium.

RANCONA 3.8 FS does not provide activity against Pythium spp. or Phytophthora spp. To provide best seedling protection against a wide array of fungal pathogens, use RANCONA 3.8 FS in combination with a product containing metalaxyl (such as MetaStar ST) at the label rate registered for your crop and disease complex. Consult the label for appropriate use rate and follow all use instructions and precautions for both products. Do not use with other seed treatment products unless previous experience assures compatibility.

RANCONA 3.8 FS may be applied as a water-based slurry with other registered seed treatment insecticides and fungicides through standard slurry or mist-type commercial seed treatment equipment.

Not for use on agricultural establishments in hopper-box, planter-box, slurry-box or other seed treatment applications at or immediately before planting.

NOTE: This product is undyed.
