Boxwood moth
About a week ago I noticed a brown spot on a conically trimmed box in our garden, thought it was getting dry and needed water so I watered it. Two days later half of it was brown and covered in cobwebs. Sprayed it with insecticide but a couple of days later it was completely brown and I removed it.
This was the culprit: http://www.gerbeaud.com/jardin/fiches/p ... ,1402.html
I'm now spraying a 6 metre long box hedge that has developed brown patches with bacille thuringiensys but without much hope of success.
So, if you have box hedges or topiary keep a close eye on them.

Each moth lays several hundreds of eggs and there can be three generations a year. So, if they all survive (fortunately unlikely) one moth will produce,say 500 x 500 x 500 = 125 million offspring! Good luck with catching them all.Sus wrote:I might try the water and/or see whether I can actually catch the caterpillars

Indeed. I believe you can either have box, or you can have the moth, but you can't have both as, once infested, the bush is completely destroyed in a couple of days. They're voracious eaters.russell wrote:Each moth lays several hundreds of eggs and there can be three generations a year.

A local friend managed to save the life of his very sick moth-eaten box hedge by using a power-washer to blast the hell out of the critters and surprisingly the plants survived. He must have been in the nick of time.
