Box Tree Caterpillars are decimating the Box Hedging.
I've just sprayed with Grouzvei BoxTree Caterpillar Rescue solution. I'm not convinced about this organic/natural remedy, I'd prefer something deadly, manufactured in a chemical lab by Bayer or such like.
Has anyone had experience with such a product for the job? Any recommendations?
It pains me to see a twenty year old hedge being destroyed. Tia, for any response from the gardeners amongst us :tiphat:

Morning
My folks had it quiet bad a couple of years ago and they used something called Xentari to good effect

You'll struggle to get rid of them.
I tried every remedy going over a 2 year period trying to save a 140 plant design and ended up digging them all up and re landscaping the area, expensive project.

I even dug out the worst affected shrubs to start off with and replaced them with Euonymus shrubs which are not prone to disease.

That's my worst nightmare, just got a lovely hedge separating the gravel drive from the pathways, and this happens when I've got it in my head to downsize and have more time for shooting & fishing. The hedging really softens the front of the house up.
 
They absolutely decimated pretty much all the box hedging around here 3 or so years back, it was very sad to see especially where owners had very clearly taken years to nurture & develop hedging that was part of the character of their property.
 
Once its there, you need to spray multiple times a year, every year. Also any other box in the area will have it.
I think its a loosing battle. I dont think spraying insecticide repeatedly is a good idea.
I would dig it out and change for something else.

Yes that would certainly do it, but it would also kill any other insects which came into contact. What you need to use is a product containing bacillus thuringiensis, which is a bacteria which only attacks caterpillar. Commercially I use dipel but you can buy the domestic version on amazon as xentari. Its an organic product so can be used on your cabbages safely as well.
 
However, box moth is here to stay. I used to sell thousands of box for hedging and topiary, but last yr none. We have moved on to euonymus green spire or yew for low hedging as it does not have the same issues with blight or caterpillar.

I've got some Yew hedging along the bottom boundary, really nice and robust.
My Box is low, only 18" - 20" high. I'll look for some Xentari.
Thanks for the info.

I used the nematode worm egg spray last year and that’s worked a treat
