Presidio Fungicide

DIRECTIONS FOR USE:

USE INFORMATION

Presidio Fungicide is formulated as 4 lbs ai/gal suspendable concentrate (SC). The active ingredient in Presidio Fungicide is fluopicolide. Presidio Fungicide exhibits protective, curative, eradicative and anti-sporulant activity. Fluopicolide is locally systemic and translaminar and also moves systemically via xylem tissue.

Presidio 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 43 fungicides).

RESTRICTIONS AND LIMITATIONS:

• Do not apply to greenhouse food crops.
• Do not apply this product when weather conditions favor spray drift from treated areas.
• When applying by air, observe drift management restrictions and precautions listed under “AERIAL APPLICATION”. Best control is achieved through ground application.
• It is the responsibility of the applicator to ensure that spray drift does not occur from the application site. The interaction of many equipment and weather related factors determine the potential for spray drift. The applicator is responsible for considering all of these factors when making decisions. Where states have more stringent regulations, they must be followed.

MODE OF ACTION:

Presidio 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 demonstrate that fluopicolide induces a quick redistribution of these proteins from the membrane to the cytoplasm in both hyphae and zoospores.

APPLICATION INSTRUCTIONS

SPRAYER PREPARATION:

Before applying Presidio Fungicide, start with clean, well maintained application equipment. The spray tank, hoses and booms must be cleaned to ensure no residue from the previous spraying operation remains in the sprayer. The spray equipment must be cleaned according to the manufacturer’s directions for the last product used before the equipment is used to apply Presidio Fungicide. If two or more products were tank mixed prior to Presidio Fungicide application, follow the most restrictive cleanup procedure.

MIXING INSTRUCTIONS:

1. Fill clean spray or nurse tank 1/2 to 2/3 of desired level with clean water.
2. While agitating, slowly add the Presidio Fungi- cide to the tank. Adequate agitation will create a rippling or rolling action on the water surface.
3. When tank mixing Presidio Fungicide with other labeled pesticides, add water soluble packets first, followed by dry formulations, flowables, emulsifiable concentrates and then solutions. When tank mixing, follow the label directions for the most restrictive of label precautions and limitations.
4. Add any required adjuvants.
5. Fill tank to desired level with water. Continue to agitate until all spray solution has been used or applied.

SPECIFIC REQUIREMENTS - All Crops:

When to Apply: Begin application when crop and/or environmental conditions favor disease development. Make applications on a 7 to 14 day interval, depending on disease pressure, unless otherwise noted under crop specific use instructions. Under severe disease pressure or if rain is expected, use the higher labeled rate and shortest interval. Apply as a foliar spray in sufficient water to obtain thorough coverage. Chemigation is not recommended when the primary disease is downy mildew or other foliar diseases.

Resistance Management: Presidio Fungicide must be used as part of an Integrated Pest Management (IPM) program. When tank mixing is required in the crop specific use instructions, use with another labeled fungicide product with a different mode of action on the target pathogen in sufficient water to obtain thorough coverage.

Restrictions and Limitations:

• The maximum Presidio Fungicide application rate is 4 fl oz per acre per application and 12 fl oz per acre per season.
• Apply no more than 2 sequential applications of Presidio Fungicide before alternating with an effective fungicide from a different resistance management group, unless otherwise noted under crop specific use instructions.
• Do not make more than 4 applications of Presidio Fungicide per acre per season, unless otherwise noted under crop specific use instructions.
• In Hawaii: Apply Presidio Fungicide by foliar and chemigation (sprinkler irrigation) only.

ENVIRONMENTAL HAZARDS:

This pesticide is toxic to fish and aquatic invertebrates. Do not apply directly to water, or to areas where surface water is present or to intertidal areas below the mean high water mark. Drift and runoff from treated areas may be hazardous to aquatic organisms in water adjacent to treated areas. Do not contaminate water by disposing of equipment washwaters or rinsate.
