Peach leaf curl Taphrina
Does anybody have good KNF routine to prevent Taphrina on peach trees in spring?
Top answer
From the KNF library
Drake describes LAB as the KNF protectors. They colonize first, so bad microbes have to fight through trillions of good ones. (Office Hours Ep. 21, 53:40)
For powdery mildew, Drake says to spray LAB early and often as new leaves emerge. Every spot on the leaf is then occupied before spores land. (Office Hours Ep. 34, 48:06) He gave that advice for mildew, not for leaf curl. (Office Hours Ep. 34, 48:06)
Drake's own peach tree went from 24 lbs of fruit to 72 lbs, and its old fungal issue is gone since starting KNF treatments. (Office Hours Ep. 92, 1:04:33) That answers Balint's question about whether this is only theory. It is Drake's own tree, but the library does not say which fungus it was or which treatments he used.
In the fruit tree chapter, Cho has farmers make fermented plant juice from harvested fruit and spray it on stems or leaves. (Cho, Theory, p. 111)
The library does not name Taphrina. It gives no peach-specific spray schedule, no dilution, and no percent of leaf curl avoided.

Thanks. Is it your own pest management routine on your peach trees with success? If yes, how many percent of leaf curl can you avoid? Or this is only theory? Last season I failed with LAB in grapevine. 95% of my plants lost the full canopy in the middle of summer.Thank you for sharing your expeience. Balint
