Malathion mixture for orchids
How much 50% malathion per gal. of water is needed to treat for scale
and other nasties on orchids? The directions on the malathion package
are not specific about orchids, referring only to "ornamentals." I
think 2 teaspoons per gallon is what I want, but I am not sure.
Are there any orchid genera which will be harmed by malathion?
