You’ve seen fire blight on ornamental and fruiting pear trees – brown to black leaves, twigs and branches appearing as if scorched by fire.
There is no cure for fire blight once a tree is infected. It is caused by bacteria and is destructive and highly infectious and therefore a widespread disease.
The disease enters a tree through natural openings, especially flowers in spring. It moves from the new growth to older growth quickly and can be spread from diseased to healthy plants by rain, wind and pruning tools.
You can help prevent the disease by spraying your pear tree with Ferti-lome Fire Blight Spray when the tree starts flowering during spring. This helps prevent the disease from entering through the blooms.
