I have green worms on my broccoli.

BT AKA Bacillus Thurigensis works quite well. It's the spores of a disease
that kills cabbage moth larvae (the green worms in question). The stuff I
got is a powder you mix with water and spray on the plants. The worms stop
feeding almost immediately after ingesting it, and die a few days later.
Harmless to people, unless great-great-great grandpa was a cabbage moth.
There are varieties that work well on potato beetles as well.
You need to re-apply after a rain if there are still worms present.
See also "bug juice," though the family may not want to use that blender
for marguerites afterward...
