Some thoughts about peach leaf curl came to mind:
- I read from some articles in an Italian fruit growing magazine of the 1950s/60s that from field tests, with a single treatment of 2% Bordeaux mixture at the end of winter the fungus can be totally eradicated. But it doesn’t work for me! Could it be due to the different varieties I have or the climate that has changed over time??
- In general it is advisable to carry out the last treatment close to the breaking of the wood buds. However, this year I saw that the plants that were firmer at the time of treatment developed very little peach leaf curl, while the others more. Why do you think so?
