CULT: Murphey's, Oil, and Borer

If it is  the oil that kills the borers (I imagine by suffocating them) 
then perhaps  a good solution (no pun intended) would be SunSpray 
Ultra-Fine Oil. It is  an ultra refined parafinc oil. I use it here in 
California to control  Whitefly. Pests don't develop an immunity to it 
because of the way it  works.  Non-toxic.


They  don't list any borers o\r the like, but that just means they 
haven't  tested it.

And that is an idea that appeals to me, too. In fact I've thought for years  
that dormant oil might be the way to go for borer. 
I use SunSpray a lot here, too. One thing it is superb for is  doing the deed 
on some houseplants before bringing them in for the winter. I  have a ten 
foot tall Laurus nobilis--culinary bay tree--a five foot bay  standard, a three 
foot female bay standard, a kumquat, some XFatshedera and  ivy, and a gardenia 
standard which are all prone to cooties in the house,  notably scale of one 
nasty sort or another. I spray them down twice before  bringing them and have 
few problems. 
There are heavier weights of horticultural oil that are used on one or  
another sorts of plants outside, with limitations as to season and conditions,  and 
they could also have some potential as a borer treatment. The way I see  it, 
if the eggs are in nooks and crannies at the base of the dormant  fans--the 
only place they could be since one has so scrupulously cleaned up the  debris in 
the bed ( :>)--then getting a good deal of dormant oil running down  into 
those places could just get some or all of them. 
Assuming, of course, that the eggs of the borer are among those which  are 
actually smothered by such a treatment--are there some inselct eggs which  are 
not? anyone know? 
What is the deal on Cygon these days? Wasn't it taken off the market? What  
is AIS 'officially' suggesting for borer now, if anything, other than good  
garden hygiene, Merit?
