Charlie,
Check again--there should only be one type of sevin--sevin is a trade name
for carbaryl, a "moderately to very toxic" substance. Check out:
http://ace.orst.edu/cgi-bin/mfs/01/pips/carbaryl.htm
Extoxnet is very good to find out pesticide information:
http://ace.orst.edu/info/extoxnet/ghindex.html
For aphids if insecticidal soap doesn't work UC Davis recommends a number of
things possibly safer to use than sevin. See:
http://www.ipm.ucdavis.edu/PMG/r604300111.html
One chemical they recommend is IMIDACLOPRID, which is related to nicotine.
To confirm what Rael sez, I've had good luck with a homebrew of nicotine and
soap. There're recipes around. Boil the tobacco if Tobacco Mosaic Virus
concerns you.
There're some 3rd generation pesticides, synthetic derivatives of natural
pyrethins, that seem to have good environmental characteristics. Personally
I haven't had to use pesticides for chiles, but here in California we have
Argentine ants which have killed (as in _extinct_) the native ants and have
no natural enemies. A 3rd gen ant bait works ok with them.
Insecticidal oil (Neem???) oil seems to work well with whitefly.
Hot regards,
Riley
