Frequently Asked Questions
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.
Spray ZT Pesticide - Ready to Use (“RTU”) once a week as a preventive OR spray at the first sight of infestation. Always use in the evenings. Avoid exposure to direct sunlight immediately after use.
Mist all leaves, underside of leaves, and branches. Mist leaves completely but not to where they are dripping wet. Avoid over spraying.
Slight leaf spotting or discoloration will not affect overall health of plant. If damage or burning appears, add 1 cup of water to 1 quart ZT Pesticide/Fungicide RTU. Test again. For stressed or small plants dilute 1 part ZT Pesticide/Fungicide RTU with 1 part water.
Yes, only if the plant is healthy. Dilute 1 part ZT Pesticide/Fungicide RTU and 1 part water.
Rather than using it in a reservoir directly, shut the system off and water the medium with a solution of 1 part ZT Pesticide RTU and 2-3 parts water
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.
Besides spraying around the base of the plant, it is best to pour ZT Pesticide RTU directly into roots and soil. Dilute 1 part ZT Pesticide RTU with 2 parts water and pour directly to roots and soil. **Beneficial nematodes are the most effective solution against root aphids and root rot.
Use ZT Fungicide RTU at first sign of infection, then every third day as needed. Reapply after rain and watering.
Zero Tolerance can be applied up to 10 days before harvest. The oils will all evaporate over a four to five day period so there is no after-taste or oil residue.
