We sprayed half the orchard with a combination of Surround clay powder, Dipel (BT), liquid Kelp, liquid Fish, and “EM1” (effective microbes). The Nursery orchard block has a lot of Fire Blight. When the bacterium Erwinia amylovora is present in the orchard along with a simultaneous combination of warm temperatures, moisture (rain or even heavy dew) and apple trees, pears or quince in bloom, it makes for the perfect conditions for an infection that causes branch tips to wilt and die. It’s ugly. Any infected branch tips should be cut back. The trimmings can be left on the ground to dry out and become innocuous. Or you can compost them or take them to the landfill. It’s a bummer, but we’ve had it before and most of the trees should survive.
