| It's looking like the plum curculio has gotten nearly every apricot on the three trees I have. At least, every apricot low enough for me to see. They've never been a problem in the past here at all. Is this an especially bad year for them? (I'm in western NY) Or is it more likely that they just hadn't found my trees yet before? They've also gotten a lot of the peaches and a fair number of the apples. Is there anything to be done at this point? Will any of the fruit still be edible, or should I just start picking now to try to prevent the next generation? From what I've read, it sounds like maybe the apples will be okay, but not the stone fruit? Also, there's a spot on one of the trees that is oozing. Is that a related issue, or do I need to look for another cause for that one? |

| The curculios are out in SE WI in big numbers. I sprayed Imidan 9 days ago but we got 1/2" rain the night after I sprayed and heavy rains the next two days. I sprayed again last night. My red Delicious apples had a lot of curculio scars. Much to my dismay. Interesting that the McIntosh nearby had none that I could find. Perhaps they prefer Delicious? Curculios are not a big issue for me since I use Imidan every year but the weather and wind were against me this I hope my Stanley prune plum is ok. I can live with a scar on my apple but not with larvae in my plums. |

| So, with apples they scar, but don't otherwise damage the fruit? I can live with scars, too. This is the first year that the tree my son picked out as "his" has set fruit, so I'm really hoping he gets to eat some. As for the stone fruit... Does a crescent shaped wound mean that an egg has been laid there? I assumed so, then read that they make a slit, then go off and mate, then come back and make a new slit and put the eggs in that or something. |

| I have a scar on nearly every apple this year. I think I know what I did wrong. Being new and trying to follow instructions I knew to wait until after petal fall to spray insecticide. Well I waited until EVERY single petal had fell and then even a week later. Too late I think. |

| Horrible here in my yard. Worse i've ever seen. I got a late spray on my big plum and i've counted 3 clean fruit out of probably 200+...which i've tossed in the garbage... I had them hit the apples (What little there is), sour cherries and pluots...everything else was sprayed and seems to look good. Most of it is my fault (not spraying soon enough). I've seen plums with 10+ egg laying scars on them. I've seen pea size plums with egg laying scars. I have wild plums near my house, so that can't be helping. |

| The curc is an unforgiving little booger. For stone fruits if you really want to try to keep some in spite of scars, wait and see if they keep growing or slow down. If they keep growing and are not starting to hang loose or shrivel or change color, they are good (or, the seed hardened before the curc could eat it -- happens on apricots sometimes). Nearly all with crescents are probably infected but you may have a few good ones. Don't test them too long, you want to pick and clear out all the bad ones to break the cycle and once they start falling to the ground you may miss some. Scott |

| I had good luck with the recommendations in the Holistic Orchard book last year, but this year, I neglected to clean out the sprayer after the first spray of the year, and sludge formed that clogged things miserably. Finally got it cleaned out, and in the meantime, the metal wand seems to have corroded, so the spray shoots out the sides. ugh. I cut open all the drops today to see what we have, and even the ones that looked fine on the outside were riddled with worm holes. |

| Also, on a small portion of the apricots, the wounds are oozing. Is that still curculio, or something else? Why aren't all of them doing that? |
|
| They have hit our area sooner then last year and I really thought with the harsh winter there wouldn't be that many but I was wrong to. I was one day to late this year waited because I didn't want to kill the bees, but I should still have a good apple crop... |

| Christyroc: To answer your question, curculio eggs seldom ruin pome The flesh under this mark will be fine as curculio basically |
