Post Gum leaf skeletoniser

Hi Guys,
just wondering about your take on gum leaf skeletoniser de-foilagization. Gum leaf skeletoniser has become a real problem and has increased considerabliy of late also attacking lephostemons and even oaks and ash if it is near gums, we have trialed some stem injection methods for insecticide to kill them and noticed in the tree world video a syringe type method we have tryed, the side winder back pack seems to be the best so far, have you guys had any problems??

Some links and a PDF.

Doesn't appear chemicals will be effective and may knock out the good guys too. They talk of some biological control fungus.

If you look at chemicalcontrolsforeucs PDF there's some mixing ratios ... in the Dimethoate row is the ratio for mixing for stem injection. Note the ratio is 50/50 chemical to water, however note you should be using Maldison and there's no mix ratio for injection.

Over here there's many "no mix" ratios for injecting, like unconquered ground! But if you look at the Dimethoate ratios for foliage spray vs injection you'll see the similarity ... so what I'd do is mix it 50/50.

I can't remember the last time I came across any kind of "skeletonizer", but I remember liking the name since the first time I heard it in college: Pesticides class and the Weed, Insects and Plant Diseases class...

"Skeletonizer..."

Sounds tough, doesn't it.
