Peach Leaf Curl


As a by the way…. just because its called peach leaf curl, it doesn’t mean it only affects peach trees. It will affect most Prunus related species.

Anyhow, I don’t like this one at all. It simply looks so ugly…. caused by the fungus Taphrina deformans [the second part of the name says it all…], it is spread by rain and wind where it will hibernate in stem cracks, scars or wounds and there is literally damn all one can do about it.

The leaves become distorted and bubble up like big ugly red blisters. En mass, it is pretty ugly to look at and I kind of feel sorry for the plant…. especially when all of the leaves fall off.

Whilst chemical control via any sort of fungicide will do the job… in my own garden I prefer to let nature do what it must and maybe from a biological control point of way I may get involved…. But the leaves do grow back and hopefully the plant will come good. But isn’t that what gardening is all about…

    For this, last winter I have used a combination of mineral oils and copper (3%) – we call it red oil. Its sprayed on trees in January when there are not leaves or buds. It actualy worked great – we did not have any curly and red leaves this year. Leaf Curl doesnt realy do anything to fruits or to trees, its just looks nasty.

    my initial assumption is that it may cause some degree of reduction in photosynthesis; and in the commercial sense that this may be a concern of sorts [?]. In the domestic sense – very logic thinking regarding the leaf curl.

    Nice to hear that chemical control isn’t always the answer.

    best wishes
