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. KILLS & REPELS: Spider Mites, Aphids, Whiteflies, Thrips, Ants, Caterpillars, Gnats, Root Aphids, Mealy Bugs & Scale   The best way to get rid of bugs is to make sure they never move in. Zero Tolerance works well when used as a preventative measure. Once your garden is infested, it’s a lot harder to remove them. Please keep in mind that Zero Tolerance is a natural garden solution and not some high-powered deadly chemical. This means a bit of time and your care are needed to address your infestation problem. Here are a couple of pointers: 1.   Using it once will not solve the problem - multiple applications are needed.  [Spider mites need a minimum of 3 applications] 2.   You MUST test Zero Tolerance on a leaf before you apply it to your plants.  DO NOT USE ON WILTED OR STRESSED PLANTS.  Wait 24 hours to make sure your concentration is at a safe level of dilution for your plants.  Zero Tolerance is very strong and can burn your plants.  3.   The best time to spray is in the evening or when plants are not under bright light. DO NOT SPRAY UNDER GROW LIGHTING OR PEAK SUN-TIMES. 4. Ed uses the finest natural ingredients to make sure your plants are healthy, and is safe to use on edible plants also. Be patient and the results will be amazing Spider Mites: how to apply? Spray ZT Pesticide RTU on days 1, 4, and 7. Example: Spray on day 1, wait 3 days and spray again (day 4), 3 days later spray again (day 7). This interrupts the life cycle. Continue spraying on days 1, 4, and 7 until mite infestation is eliminated, usually takes 10-14 days of use. Root Aphids, Root Rot, and Fungus Gnats: how to apply? Besides spraying around the base of the plant, it is best to spray ZT Pesticide RTU directly into roots and soil.
