Ed Rosenthal’s Zero Tolerance™ Herbal Pesticide is OMRI Listed for Organic Use. Ed Rosenthal’s Zero Tolerance™ offers advantages over other natural products, and poisonous pesticides and fungicides. ZT leaves no residue (unlike Neem oil) because the highest quality food grade oils of cinnamon, clove, rosemary, and thyme evaporate fully. It is safer for the garden than Pyrethrum, which is toxic to fish and reptiles.
ACTIVE INGREDIENTS: Essential oils of Cinnamon, Rosemary, Thyme & Clove.
