Organic does not necessarily mean “safe”

Don’t imagine that an “organic” label means “safe.” Some organic pesticides are relatively safe, it is true, in particular those that have a strictly physical action, such as soaps, horticultural oils or neem or are parasites or predators on a specific group enemies, such as Bt or nematodes. But Mother Nature also produces poisons, even deadly poisons. So be careful when applying biological products such as nicotine, rotenone and Ryana: these are pesticides ‘natural’ but toxic and should only be used as a last resort.
