Leaf curl prevention

DISTORTED and discoloured foliage on stonefruit trees including peaches, nectarines and plums is caused by a fungal disease called leaf curl.

The tree ends up looking awful and in severe cases it reduces the tree's ability to photosynthesise, which in turn can affect plant health and fruit yield.

Leaf curl disease spores lurk in bark crevices and around leaf buds during winter, waiting to infect the newly-emerging foliage in late winter and early spring.

It is a disease that needs to be prevented by killing the disease spores before they infect the new leaves, as the damage done by leaf curl is irreversible.

To break the leaf curl disease cycle, spray stone fruit trees during winter with lime sulfur.

Lime sulfur will also control other diseases like freckle, rust and shot hole which hide on fruit tree stems during winter.

Spray all stems and the trunk thoroughly before new foliage emerges. This will help give fruit trees a disease-free start to spring so they can concentrate on giving you a fantastic harvest.
