Pests...In Particular Japanese Beetles

thaprankstaJune 15, 2012

I have 4 fruit trees planted - 2 Japanese plums, 1 peach, and 1 Asian pear. What I have noticed as of late is the foliage on my trees is being removed by small beetles. Based on some things I've read, my first thought is that these beetles are the infamous Japanese variety.

I've also noticed that the amount of damage is varied by each tree. My J. plums have the worst damage with my Shiro looking by far the worst. My Satsuma has a good amount of damage as well but on a much lower level. My peach tree has a very small amount of damage as I last seen it. But my Asian pear tree looks completely unaffected. Do these bugs not like Asian pear tree leaves or have I just been lucky?

Also, what method do you personally use to control the J. beetles? I've read that applying Neem oil is good as well as manually knocking them into a container of soapy water. I am not sure if Neem oil will have an effect on the fruit when my trees are at an age for bearing.

Neem oil will have minimal effect, at least from what I've read...Beetles seem to always prefer plums...almost all my pests seem to go to them before any other fruit tree. Pears are usually the least preferred. I rarely have any damage to my pears other then aphids and mites.

You either pick them off often or spray with it a pyrethroid (Once and Done), organophosphate (Sevin), neonic (Bayer systematic?)...

Surround works pretty well if you need something non-toxic. I would also not count on neem to do anything.

Japanese beetles love Japanese plums....seems to make sense. :-) Where can I get this Surround since I would really prefer to do as much organic gardening as possible? I have picked up the Sevin mentioned above but I may take it back to the store.

You might have to try a farm supply type business. I bought mine at CPS...I think it was $30 for a huge bag...

You can see if they have a store near you...or just look around for this type of business. I also believe you can mail order it, but shipping might be a little high.

I see that there are two different types of Surround: At Home and WP. Is there a discernible difference between the two products? It looks like you get a lot more WP for the same price as the At Home.
