Controlled versus suppressed diseases
The label lists anthracnose, bacterial leaf blights and spots, Alternaria black mold and leaf spots, black spot of roses, gray mold and powdery mildews as controlled.[1]
Downy mildew, early blight, late blight, fire blight, pin rot and scab are listed as suppressed only, so expect partial results on those.[1]
Where it is used
Spray just enough to wet all leaves and fruit with little dripping. Repeat as needed to hold disease back, usually every 7 to 10 days.[1]
For root and crown diseases, drench the soil or the transplant hole. Give each transplant about 4 fluid ounces of mix before planting, and don't water potted plants again for 24 hours.[1]
On lawns, a typical 1,000 square feet takes 2 to 5 gallons of mix. Water it in, or spray just before light rain, for soilborne root and crown diseases.[1]
It can be applied up to and on the day of harvest. Test near vinyl siding before spraying close to the house.[1]

Safety and environmental hazards
People
The residential sublabel carries no signal word or hazard statement beyond keeping it out of reach of children. Commercial handlers wear a respirator because repeated exposure to concentrated microbial proteins can cause allergic sensitization.[1]

The home sublabel gives no pet-specific precautions; it says to keep the product out of reach of children and store it in the original container.[1]
Bees and pollinators
The label has no bee or pollinator hazard statement.[1]

Keep it out of storm drains, ditches, gutters and surface water. Applying in calm weather with no rain due for 24 hours keeps it on the treated area.[1]
