USE SUMMARY Foliar SprayFor control of Rhizoctonia spp., Alternaria spp., Septoria spp., Myrothecium spp., and Cercospora spp., use 1-2 fl oz/100 gal of water and spray to runoff at 7 to 14 day intervals. For control of Botrytis spp. use 2-4 fl oz/100 gal of water and spray to runoff at 7 to 14 day intervals. For management of the potential development of resistance in the Botrytis population, use no more than two consecutive applications before rotating to another effective
product registered for Botrytis control on ornamentals with a different mode of action.
Notes: Under severe conditions, use the highest rate and/or the shortest application interval. Use sufficient spray volume to wet the plants to the point of drip. For a single foliar application, apply up to a maximum of 4 fl oz/100 gal (1 fl oz/25 gal) (0.188 lbs ai/A).
Pre-Potting Growing Media MixSpirato GHN Fungicide can be mixed with the potting media before seeding or transplanting by uniformly mixing 1-2 fl oz/cu yd of potting media. The desired amount of Spirato GHN Fungicide should be mixed with 5-10 gal of water and applied to 1 (one) cu yd of potting media. Treatment should be made just before the plants are seeded or potted up.
Medium Drench At Seeding GrowFor the control of damping-off, root, and stem diseases, mix 1 fl oz/100 gal of water. For control of Rhizoctonia spp., apply sufficient mix to wet the upper one-half of the growing medium. For control of other root and stem diseases, completely drench the growing medium. Make only one application to the seeding crop prior to transplanting or transfer to larger containers.
Growing Medium Drench for Transplants and CuttingsFor the control of root and stem diseases, mix 1-2 fl oz/100 gal of water. For control of Rhizoctonia spp., apply sufficient mix to wet the upper one-half of the growing medium. For control of other root and stem diseases, completely drench the growing medium. If needed, retreat transplants and cuttings at 21 to 28 day intervals.
Notes: Under severe conditions, use the highest rates and/or the shortest application interval. If Pythium and/or Phytophthora diseases are suspected in addition to root rots caused by Rhizoctonia spp., Cylindrocladium spp., Thielaviopsis spp., Fusarium spp., and Sclerotium spp., tank mix Spirato GHN Fungicide with labeled rates of a fungicide labeled for control of these diseases, such as Adorn and Alude. Drench applications can be made at up to a maximum of 2 pt/sq ft to wet the root zone of plants (1.6 lb ai/A).
Maximum Use RatesFor indoor drench applications, use up to 30 fl oz/1000 sq ft/year (10 gal [40 lbs AI] per acre).
Applications to pre-potting mix can be made up to 4 fl oz/cu yd.
For field grown and landscape ornamentals, apply up to a maximum of 1.5 fl oz/1000 sq ft/year (0.51 gal [2.04 lbs AI] per acre). The single maximum application rate is 0.68 lb fludioxonil/A/application. For outdoor container grown ornamentals, apply up to a maximum of 3 fl oz/1000 sq ft /year (1 gal [4 lbs AI]/A/year).
