Foliar application

1 oz./A

Apply preventively. Make up to four applications on a 7-day schedule. Begin applications 7-10 days after thinning.

FAILURE TO FOLLOW DIRECTIONS AND PRECAUTIONS ON THIS LABEL MAY RESULT IN CROP INJURY, POOR DISEASE CONTROL, AND/OR ILLEGAL RESIDUES.

Notes:
Apply in sufficient water to ensure adequate coverage using a minimum of 20 gallons of water per acre. If downy mildew is present in the production area, the first application should be made in tank mixture with another registered downy mildew fungicide; once activated, the supplemental applications of Actigard 50WG should be applied alone.

Notes:

1. Allow 7 days between the last application and harvest.

2. Do not make more than 4 applications per crop per year.

3. Do not apply more than 4 ounces of Actigard 50WG per acre per season.

Actigard 50WG is a selective, systemic compound used for the control of downy mildew of cole crops and leafy vegetables, bacterial leaf spots of tomato, and blue mold of tobacco. Actigard 50WG is an inducer of host plant resistance. Actigard 50WG exhibits a unique mode of action which mimics the natural systemic activated resistance (SAR) response found in most plant species. Actigard 50WG has no direct activity against target pathogens.

For best performance, always follow these directions:

**Actigard 50WG should be applied to plant foliage preventively, before disease is observed in the field.

**Actigard 50WG moves systemically within the plant; however uniform spray coverage is essential for best performance. Apply Actigard 50WG in sufficient water to ensure uniform coverage (see specific water volumes for each crop in Directions for Use tables).

**An Actigard 50WG application mimics the SAR response in plants. Maximum disease control is normally obtained 4 days after an Actigard 50WG application.

Actigard 50WG provides protection against certain diseases in the crops listed on this label. Actigard 50WG provides sufficient protection to reduce disease levels but should be tank mixed with other registered products with curative activity if disease is present at the time of application, to ensure adequate disease control or to broaden the spectrum of disease control.

Resistance Management

Actigard 50WG exhibits a mode of action unique from currently available fungicides and bactericides. Since Actigard 50WG has no direct activity on plant pathogens, the likelihood of pathogen development of insensitivity is low. However, plant pathogens are known to develop tolerance to host plant resistance and to products used repeatedly for control. Because insensitivity development cannot be fully predicted, the use of this product should conform to sensitivity management strategies established for the crop and use area. Such strategies may include rotating and/or tank mixing with products with different modes of action as well as the use of good cultural practices. Consult your local pest control advisor or extension office for details. If insensitivity to this product develops in your area, this product or other products with a similar mode of action may not provide adequate control. If you experience difficulty with control, and insensitivity is a likely cause, consult your local Syngenta Crop Protection representative, local agricultural extension office, or pest control advisor for the best alternative method of control. Syngenta encourages responsible product stewardship to ensure effective long-term disease control.
