Read the label:

Do not use within 14 days on Chinese cabbage, collards, kale, or mustard
greens.


"BT" might be a better choice, and is nontoxic.

I haven't used anything on my herb garden, but something is chowing on
my sage plant now. Would BT be a good choice there? Thanks!- Hide quoted

Bt is the best choice for any type of butterfly or moth larva and that
includes cabbage worms or loopers. It is very selective and virtually
harmless to other lifeforms. It also has a good degree of persistance
and can be used as preventive. It is a stomach poison so the larva
have to ingest it. Carbaryl on the other hand is a contact poison,
with a shot halflife, It will kill many insects that come in contact
with it including cabbage worms. But it is most useful on beetles. It
is not very poisonous to humans, a little less than Rotenone and has
biodegraded with 24 hours, so I don't worry about poisoning myself,
but it just is not nearly as effective on cabbage worms as Bt.


Agreed, if you think it's larvae that are attacking your sage.

Sevin is also safe around birds, but BT is better for caterpillars.

Sevin kills any insect that comes in contact with it tho' so it also
kills beneficials. The only reason I'll submit to using in desperation
sometimes it is that it is so short lived. Only works for maybe 5 days
at best, and it if gets wet, it's gone.

I use it once or twice per year for flea control. I dust the entire yard
the same day I Frontline the pets. I'm always saddened tho' sometimes
by what I find dead. Last year, I found a dying female rhinoceros
beetle. :-(

It does control the fleas tho' and I've never had a problem with tics...
