DIRECTIONS FOR USE
It is a violation of Federal law to use this product in a manner inconsistent with its labeling.
Do riot apply this product in a way that will contact workers or other persons, either directly or through drift. Only protected handlers may be in the area during application. For any requirements specific to your State or Tribe, consult the agency responsible for pesticide regulation.
READ ENTIRE LABEL. USE STRICTLY IN ACCORDANCE WITH PRECAUTIONARY STATEMENTS AND DIRECTIONS, AND WITH APPLICABLE STATE AND FEDERAL REGULATIONS.
Metconazole 50 WDG Fungicide is formulated as a 50% water dispersible granular (WDG). The active ingredient in Metconazole 50 WDG Fungicide is metconazole, a broad-spectrum triazole fungicide that works by inhibiting demethylation and other processes in sterol biosynthesis. Metconazole 50 WDG
Fungicide is systemic and is quickly absorbed into plant tissue and can move up, but not down in the plant. Metconazole has no effect on fungal spore germination, but interferes with other early developmental processes in the life cycle of certain fungi. Although Metconazole 50 WDG Fungicide cannot prevent spore germination, it prevents spore formation and inhibits mycelial growth.
Metconazole 50 WDG Fungicide can be applied pre- or post- infection, but is most effective when applied prior to infection. Optimal disease control is achieved when Metconazole 50 WDG Fungicide is 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 3 fungicides). Metconazole 50 WDG Fungicide is a sterol biosynthesis inhibitor; avoid rotating with other sterol biosynthesis inhibitors, such as Folicur, Nova, Procure or Tilt .
MODE OF ACTION
The active ingredient in Metconazole 50 WDG Fungicide, metconazole, belongs to the sterol biosynthesis inhibitor group of fungicides as classified by the U.S. EPA and Canada PMRA as a target site of action Group 3 fungicide.
Metconazole 50 WDG Fungicide contains metconazole a Group 3 fungicide (sterol biosynthesis inhibitors). Metconazole is effective against pathogens resistant to fungicides with modes of action different from those of target site Group 3 fungicides, (e.g., dicarboximides, strobilurins, benzimidazoles or phenylamides). Resistant isolates may eventually dominate the fungal population if used repeatedly at the same site or in successive years as the primary method of control for the targeted pathogen species. Selection for resistance may be particularly rapid if resistance to Group 3 fungicides is already present in the pathogen population. This may result in reduced disease control by Metconazole 50 WDG Fungicide or other Group 3 fungicides. Group 3 resistance may result in reduced disease control by Metconazole 50 WDG Fungicide or other Group 3 fungicides. To maintain the performance of
Metconazole 50 WDG Fungicide in the field, do not exceed the total number of sequential applicationsor the total number of seasonal applications of Metconazole 50 WDG Fungicide as stated in "CROP SPECIFIC DIRECTIONS, RESTRICTIONS, AND LIMITATIONS". Adhere to the label instructions regarding the consecutive uses of Metconazole 50 WDG Fungicide or other target site of action Group 3 fungicides on the same pathogens. The following recommendations may be considered to furtherdelay the development of Group 3 fungicide resistance:
Tank Mixtures: If Metconazole 50 WDG Fungicide is used in tank mixtures with fungicides from different target site of action groups that are registered and/or permitted for the same use and that are effective against the pathogens of concern, Valent recommends using at least the minimum labeled rates of each fungicide in the tank mix. Do not tank mix with any product which contains a prohibition on tank mixing. Follow the more restrictive labeling of any tank mix partner.
Integrated Pest Management (IPM): Metconazole 50 WDG Fungicide should be integrated into an overall disease and pest management program. Cultural practices known to reduce diseasedevelopment should be followed. Consult your local extension specialist, certified crop advisor and/or Valent representative for additional IPM strategies established for your area. Metconazole 50 WDG Fungicide may be used in advisory (disease forecasting) programs, which 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/ordisease development.
Reporting: If a Group 3 target site fungicide appears to be less or no longer effective against a pathogen that it previously controlled or suppressed, contact a Valent representative, localextension specialist and/or certified crop advisor to assist in determining the cause of reduced performance.
