Fire Blight is caused by Erwinia amylovora. Disease can usually be found in apple and pear trees on stems, blossoms and rootstock. Large seeping wounds are generally seen as sources of inoculum that spread to infect and damage blossoms, severely lowering fruit yields. AgriPhage Fire Blight should be sprayed as soon as temperatures exceed 70 degrees onto the tree surface as well as through the bloom cycle.
AgriPhage is not phytotoxic and will not negatively affect beneficial organisms.
- Pre-Harvest Interval (PHI) of 0 days. May be applied up to and including the day of harvest.
- Restricted-Entry Interval (REI) of 4 hours.
Apply as a preventive to protect the blossoms from pink through petal fall.
Under severe disease conditions and periods of heavy rain, apply immediately after rainfall, and use the higher application rate of 2 quarts of AGRIPHAGE-FIRE BLIGHT per acre.
Repeat application weekly or as needed.
Use sufficient spray solution to ensure complete coverage. Avoid excessive amounts of spray solution that result in runoff.
