| I have a 4 year old Spice Z Nectaplum which is a very pretty tree, but the skin of the fruit looks like it gets infected by fungus each year (covering roughly half the fruit surface. I have regularly sprayed for peach leaf curl each fall/winter and the foliage is almost entirely clean, but the fruit seems to be particularly susceptible. I don't have a picture on me, but the appearance is irregular in shape,brown and rough.
Anybody else fighting this ? I have used both copper type and chlorothalonil based spray. |

| Those in my greenhouse look pretty much the same way. Sort of a mixture of russeting, like on a pear, and a reddish/purplish blotchy over color. I'm not concerned as long as the fruit doesn't crack. I think it's normal but probably influenced by environmental conditions. Russeting on many apples is strongly related to humidity and other factors. |

| Hmmm... I have been doing some more homework and based on images online I think I am seeing the results of thrip damage. The suggestion is to spray at petal fall with Spinosad based spray. Chad |

| Chad: You might well be right. But if the fruit doesn't crack it doesn't matter. Unless you are trying to win 1st place at the county fair. |

| I have had bad thrip damage on Desert delight and Artic star nectarine. In the nursery I buy trees from I are a couple of nectaplums and they had thrip damage. I need to spray earlier myself to head off thrip damage. |
