One tablespoon of dishwasher soap per gallon of H2O works great to kill 
aphids. I tried it using Dove soap. Works as good as a herbicide.
No kidding?  As in weed killer?  I've also had success using dishwasher soap 
for aphids.  I mixed a small dash of Dawn in a hand sprayer filled with water, 
and sprayed my Hibiscus.  It's the first time I've been successful in 
salvaging the plants -- and I've tried every poison product that has been 
recommended 
to me to get this done.   :-)       MA
