Ed Rosenthal's Zero Tolerance now comes in a powerful concentrate. It's so strong, it had to be packaged in a metal bottle! This 1-quart brushed aluminum concentrate makes five gallons of insecticide. 

This herbal Pesticide-Fungicide is made from the highest quality oils of cinnamon, clove, rosemary and thyme. ZT can be applied up to five days before harvest. (The oils will evaporate over a four to five day period.)

Zero Tolerance not only stops pests in their tracks, it smells great too! Made from pure food-grade ingredients, its plant, people and pet friendly. Zero Tolerance is bio-degradable and environmentally safe so you can use it without worry.

Works in outdoor gardens, greenhouses and indoor hydroponic systems. Zero Tolerance not only kills existing pest infestations fast, it repels against new attacks.

We've used it on our orchids and bonsai trees and saw no sign of plant stress.

Spider Mites
Aphids
