PEACH LEAF CURL: This Fungus is the bane of many back yard fruit growers. It is interesting to see the structure of the hyphae inside the deformed leaves as they emerge in Spring. They look like helical springs and I can imagine that structure contributing to the puckering of the leaves. I have a collection of heirloom peach and nectarine trees and if the Spring is especially moist a lot of defoliation occurs. There are several dormant season fungicides that are used to prevent this but once the buds start to swell there is little to be done. It only grows on varieties of Prunus persica. Plums and apricots aren’t affected.

but i never thought to look deep inside the leaves for these micro marvels! I just mourned my poor crop of peaches…
Those hyphal helices look sinister. Thanks for popping our mostly-macro bubble!
