 Re: Peach Leaf Curl
In Central Texas, we have conditions similar to the south of France - rolling limestone hills. And we grow a lot of peaches.
Bordeaux sprays in the fall (after the leaves have been shed) and in the spring (just as the leaf buds swell) usually controls leaf curl perfectly.
Wet springs can be a problem - its too much moisture that breeds the fungus. Irrigation should be drip and kept under mulch - no above ground spraying of irrigation water. If above ground irrigation is used, do so only in the morning hours. The leaves need to be dry before sunset.
A second product that also works well is called KocideŽ - another copper based fungicide. This or the bordeaux mixture can be used if necessary after the leaves come out. (Don't spray anything while the bees are doing their thing.)
A more organic approach is to use a spray of liquid seaweed. Applied every few weeks, this seems to help prevent disease in most anything susceptible to fungal leaf diseases. |
