I was curious if anyone had had any experiences with using pyrethrin as an insecticide on a food crop. Apparently its derived from mums, but i was curious about its safety. An insecticide I am curious about also contains piperonyl butoxide, which I am guessing probably has a greater chance of causing problems when used on a food source plant.

We never use pyrithens on a food source but what we do use is ecoexempt ic2 acive ingrediant is rose mary oil and peppermint oil ive found it very successful.
