Armillatox, dilution 50:1

will that do anything for pear mite?~ buds are already on the trees!

There is a horticultural soap sold specifically in place of the old Creosote based Winter Tar.

Sadly Arlene, I don't think so, at least not for Pear leaf blister mite which is what I presume you are referring to?

Spraying with provado (not when in flower) has been reported to have some effect against them.

Yes Armillitox, it stinks a bit but if I were a bug i wouldn't go near for that reason alone :-)

Thanks~none of the buds has broken yet so will give it a try~
