In the Expert book of fruit, Dr Hessayon recommends spraying apples and
pears with fenitrothian as a preventative against apple sawfly.

Last year was a bumper year for apples, but also for sawfly, so I had a
lot of very badly scarred and malformed fruit, most of which went to the
wasps. I've been looking around for fenitrothian but with no success;
garden centres and nurseries I've asked haven't heard of it.

Does anyone here know whether its still obtainable? Is it the main
ingredient of a brand-name spray which is available? Or is this one of
the substances no longer legal.

If that's the case, what do the fruit-growers of URG use to protect
against large scale insect predation? Any suggestions? It's
disheartening to have a whole crop lost or spoiled and not be able to do
anything about it.

Any suggestions and advice welcomed...
