For organic farmers, Spinosad is the first new, 
highly effective insecticide approved for use on 
organic farms that works just as well, or better 
than many conventional insecticides.  Despite its 
relatively high cost, many organic fruit and 
vegetable farmers have incorporated spinosad in 
their organic system plans, and some appear to 
be using it heavily.  

While far less risky to most organisms than the 
OPs and carbamates, spinosad is among the 
most toxic pesticides ever applied to bees.


As with most pesticides the timing and knowledge of the applicator is key to reducing a risk to 
pollinators.
