About this Organization

Specially formulated for plants by renowned author, researcher, and horticulturist Ed Rosenthal.

Ed Rosenthal’s Zero Tolerance ® (ZT) is a line of herbal pesticides and fungicides that are made entirely from ingredients derived from plants. By combining different plant oils, the products offer a potent blend that attack insects and spores in multiple ways, quickly eliminating them. The active ingredients are essential oils and the inert ingredients are vegetable glycerin and soy lecithin. There are no harmful chemicals in ZT and it is completely safe to handle and use. The products are exempt from Federal EPA registration under section 25(b) of FIFRA.

ZT offers advantages over other natural products that are used to stop spider mites and soft-bodied garden pests. ZT leaves no residue on plants because all the oils evaporate fully. It is safer for the garden than Pyrethrum, which is toxic to fish and reptiles.

Ed Rosenthal’s Zero Tolerance® comes in two formulations: Herbal Pesticide and Herbal Fungicide. It is bottled as both a Ready-to-Use and a Concentrate.
