Pesticide

A pesticide is a substance used in agriculture to treat crops to guard against pests.

In 2365 William T. Riker suggested crop failures in The Armada may have been caused by mis-applied pesticides. However, as the farmer Hommun informed him, The Armada was certified organic so did not use pesticides - instead they controlled pests by introduced pest controlling insects and birds to The Armada's ecosystem.
