Pyrethrum 5EC is registered as suitable for organic and non-organic farming as it kills pests quickly, leaves no toxic residue and edible food crops can be safely harvested only 24 hours after application. Pyrethrum 5EC is a natural insecticide made from dried Chrysanthemum flowers and it is registered as suitable for both organic and non-organic farming.
