Ferti-Lome® Fire Blight Spray

Fire blight can destroy years of orchard investment in a single season — and Ferti-Lome® Fire Blight Spray gives you a targeted, effective tool for protecting your apple and pear trees at the critical bloom-time window when infection risk is highest. A dry concentrate that mixes easily with water, it controls fire blight and a range of other bacterial and fungal issues with a proven spray program timed to the bloom cycle. Also effective on roses. A Stark Bro’s customer favorite for orchard disease protection.

Why Bloom Time Is the Critical Window

Fire blight spreads through open blossoms — the brief period when apple and pear trees are most beautiful is also when they’re most vulnerable. Bacterial infections enter through the flowers and move into the branches, causing the characteristic “scorched” wilting that can spread rapidly through a tree. Protecting the blossoms before infection has a chance to establish is the most effective strategy for keeping fire blight out of your orchard.

Proven Application Schedule

For best results, begin spraying at the start of blossom time and repeat every 3–4 days through the end of bloom. Apply an additional spray 5–7 days after blooms end, particularly when warm, wet weather conditions favor the spread of bacterial disease. Do not apply when fruit is visible. Follow all label instructions carefully for correct dilution and timing.

Ferti-Lome® Fire Blight Spray also controls bacterial wilt, stem rot, leaf spot, and crown gall — a broad range of bacterial and disease issues beyond fire blight alone — and may be used on roses in addition to apple and pear trees.
