GENERAL INFORMATION
Stellar Fungicide is formulated as 5.7 lbs ai/gal suspendable concentrate (SC). The active ingredients in Stellar Fungicide are fluopicolide and propamocarb hydrochloride. Stellar Fungicide exhibits protective, curative, eradicative and antisporulant activity. Fluopicolide is locally systemic, translaminar and also moves systemically via xylem tissue.
Stellar Fungicide is most effective when applied in a regularly scheduled spray program used in combination and/or rotation with other effective fungicides that have different modes of action (i.e., non Group 28 & 43 fungicides).

MODE OF ACTION
Stellar Fungicide is active against selective oomycetes. It exhibits the typical mode of action of specific systemic fungicides against oomycete fungi affecting several steps in the reproduction cycle. Biochemical studies have shown that fluopicolide has an effect on spectrin-like proteins, believed to play a role in maintaining the membrane stability in ascomycete fungi or oomycetes, especially during hyphal tip extension. Microscopy studies demon- strate that fluopicolide induces a quick redistribution of these proteins from the membrane to the cytoplasm in both hyphae and zoospores. Propamocarb is believed to effect lipids and mem- brane synthesis, resulting in altered cell membrane permeability.

RESISTANCE MANAGEMENT
Stellar Fungicide contains fluopicolide and propamocarb which are group 43 & 28 fungicides, respec- tively. The target sites of action of Groups 28 & 43 fungicides are specific but the biochemical modes of action are not known. Fungal isolates with acquired resistance to fluopicolide and propamocarb may eventually dominate the fungal population if Stel- lar Fungicide is used repeatedly and not rotated orcombined with other modes of action. Repeated use may result in partial or total loss of control of these pathogens by Stellar Fungicide. To maintain the performance of Stellar Fungicide do not exceed the labeled number of sequential or seasonal appli- cations in the “Directions for Use”. Adhere to label instructions regarding the consecutive use of Stellar Fungicide. The following recommendations may be considered to delay the development of fungicide resistance:

• Integrated Pest Management (IPM): Stellar Fungi- cide must be integrated into an overall disease and pest management program. Follow cultural practic- es known to reduce disease development. Consult your local extension specialist, certified crop advisor and/or Valent representative for additional IPM strategies established for your area. Stellar Fungicide may be used in Agricultural Extension advisory (disease forecasting) programs, that recommend application timing based on environmental factors favorable for disease development.
• Monitoring: Monitor efficacy of all fungicides used in the disease management program against the targeted pathogen and record other factors that may influence fungicide performance and/or disease development.
• Reporting: If a Group 28 & 43 target site fungicide appears to be less or no longer effective against a pathogen that it previously controlled or suppressed, contact a Valent representative, local extension specialist, or certified crop advisor to assist in determining the cause of reduced performance.
