Default [IBC] Lime Sulfur

I am printing the label for lime sulfur, just so some of you
will learn how to read a label.

Which is all well and good; as Nina says, ALWAYS read (and
follow) label instructions.

There is a more basic point, however: Do you have reason to
believe that you NEED to spray your bonsai (you don't say which
kinds you have)? Is there mildew, black spot, various scales,
etc., as the label says LS will control?

On bonsai, at this time of year, I'd tend to doubt it.

Despite the various pesticide labels, there are VERY FEW
pesticides that PREVENT infestations. LS _may_ prevent some
fungus-caused diseases for apples (and other members of the rose
family). Maybe. Otherwise, manufacturer's claims to _prevent_
an infestation are based more on their desire to sell product
than it is to save your plant from voracious predators.

There's no point in applying it to control insects -- scale,
etc. -- if there are no such insects present (and ONE scale does
not make an all-out attack necessary!!!).

It is always better to spray ONLY when necessary. These things
are designed, man-made, POISONS. With rare exceptions -- of
which lime sulfur is NOT one -- they also are indiscriminate
poisons. They kill good bugs as well as bad bugs; LS is as
likely to kill "good" soil-based fungi as it is to kill the "bad"
ones.

Spraying isn't something one just does "for the heck of it."
