Plum Curculio

no, Splash I think I will have to check in the morning.


I appreciate your glass half full approach. I wish you best of luck bringing that branch back to where it belongs.

I didn’t clean up under my stanley prune plum and lost ALL of the fruit. How long do the curculios stay on the ground, and is there a spray that is effective on adults?

It looks just like my shiro. The yellow plum w the broken branch

I have a Shiro and with its lower fruit set the plums where 2-3x as big and they defiantly taste diffrent from each other.

You have to stay positive

Did you get an answer on this? I’m wondering something similar

Apples will suffer from June drop no matter what. PC usually get crushed in most apples and only cause scaring. PC over winter under leaves up to 1/4 miles away so trying to kill them in the soil around the tree is not useless but only part of the battle. You can rescue infected fruit and kill the newly implanted larva with neonicotinoids. Neonicotinoids are of course highly toxic to bees and everything and persist far longer then manufactures will admit to.

PC’s are not difficult to kill you can do so with many less then extremely toxic pesticides its challenge is timing when there most active as many of these are contact killers and break down quickly.


I definitely see new curc bites on my prune plums. Always lots of drops this time of year

you live close to me. i’d like to compare our shiro fruits some year. sounds like mine are very different from yours. mine is from stark bros. where is yours from and does it ripen early july?

Here is my Shiro, picked today.


Nice. What is the good looking peaches(can’t tell they are fuzzy or not)? Are they taste good?

It is Eastern Glo nectarine. It is a combo of acid and sweetness like 60+40. Brix is between 13-16. The 16 brix is very good and more balanced. People to prefer more acid, not just sweetness in their fruit would like this one.

Youre in central MA, I’m in central NJ. Your fruits are pretty ripe. I picked mine I guess about a week before that. And about a month ago. Sounds about right. Size and looks seem like my shiro. I still have some in my fridge. I’ll try to get a photo

When I had Shiro, the birds always got them

My Shiro have been in long bread bag sleeves. Birds also do not bother my yellow plums. Anything red is another story,

@GardenHope - most of my Shiro are not fully ripe. I only picked a dozen that were darker yellow. Most are pale yellow with some green tint to them

I distribute Kootenay Covers in the United States. You can get an idea of what the covers are and how they work at our website: The covers are very effective against codling moth, OFM and cherry fruit flies. I would like to test them against Plum Curculio this year. I do not have PC in my state as far as I can determine. If you would like to try these covers against PC this year, please contact me by email at or contact me through my website. I would appreciate your help.

If I invented a tool that would let 2 people install one of these covers easily. Could you sell it for me?

PC walk up the trunk and unless the bag closing is very secure they will be able to get though if there determined enough. Prehaps you could create a ring you can install around the trunk to make securing the bag and providing a tight seal.

I asked this question in the other PC Questions and tips thread but didn’t get a response.
Since they do crawl up the trunk, is it useful to employ Tanglefoot on a wrapped area of trunk?

From what I understand is they do have wings but they don’t fly to fruit they walk.
