Jane,

I'm only a gardener's part-time assistant (Esteemed Spouse is the Head
Gardener!) so I don't claim to know much more than I hear on the
gardening segment on Simon Marnie's ABC radio show, but....

Pestoil and white oil interchangeable? Won't white oil burn leaves if
used in the sun, whereas Pestoil is easier on foliage?

(More an enquiry than an attempt at correction.)

Yes it can. That's a good point. I looked up Pestoil and wrote a post on
it, but it looks like it didn't make it. Pestoil is white oil + UV
filter to prevent sunburn.
