Discover the Awesome Pesticidal Power of Essential Oils!

In the agricultural industry, the use of fungicides, pesticides and herbicides is commonplace. Unfortunately, these substances are often unpleasant chemicals. If you consume your produce in any way then you probably don't want to be using those chemicals on your plants. Zero Tolerance Herbal Pesticide, brought to us by grow expert and author Ed Rosenthal, utilises the power of essential oils to combat plant insect infestations. It is effective against spider mites, aphids, whiteflies, thrips, ants, caterpillars, gnats, aphids and mealy bugs, and it is safe for ingestible crops. It is listed as certified for organic growing by OMRI.

How Zero Tolerance Herbal Pesticide Works:

Certain essential oils have been found to be incredibly effective against insect infestations. Zero Tolerance Herbal Pesticide contains a blend of 4 of the most powerful insecticidal essential oils that we know of - clove, cinnamon, rosemary and thyme. These are mixed with some inert ingredients such as glycerin, lecithin and water to make a formidable foliar spray, capable of defending your plants against almost all common insect problems. When Zero Tolerance is diluted and sprayed on plants, the essential oils go on the offensive, killing existing pests and also dettering them from going anywhere near your plants.

As a bonus, the essential oils in Zero Tolerance Herbal Pesticide will also work as a fungicide against certain moulds such as powdery mildew. However, the essential oils gradually evaporate over the course of 4-5 days leaving no residues, tastes or smells. This means that to make sure that any infestation has been completely treated, Zero Tolerance should be applied at least 3 times, 3 days apart, in order to completely disrupt the insect's life-cycle

How to use Ed Rosenthal's Zero Tolerance Herbal Pesticide:

The full-strength dosage of Zero Tolerance Herbal Pesticide concentrate is 50ml per litre of water. However, this can often be too strong for many plants, particularly if they are not in absolute peak health. A lower strength is often preferable. Zero Tolerance Herbal Pesticide is a very strong solution of essential oils and should only be used at full strength on plants that are in peak health and are not wilted or stressed. Because of its strength, many growers use it successfully at half strength or lower. This helps to avoid the chance of it causing problems.

DO NOT MISS THIS STEP, DO A PATCH TEST: It is incredibly important to test one leaf with a small amount of made-up spray solution before using it all over all your plants. If the leaf has reacted negatively in any way after 24-hours then DO NOT USE the spray at that strength on the whole plant. Instead, retest another leaf with a half strength solution, then wait another 24 hours and recheck. It is highly important to find the right dosage strength for the health condition of your particular plants before spraying your whole crop.

Once you have found the appropriate dilution rate for the health of your plants with the leaf patch test described above, mix the solution at that rate with water and use a fogger or a sprayer set to "fine mist" and apply it to your plants, A fogger uses less solution overall and because the mist is finer, it is actually more effective. If you are using a sprayer, make sure it is set to "fine spray" and apply it to the underside as well as the tops of the leaves. Only spray under low light conditions. Wet leaves can become burned under intense light conditions.

Reapply Zero Tolerance every 3 days, at least 3 times (or more).

Zero Tolerance concentrate is STRONG. When handling it we recommend the use of protective gloves. Take care not to get it on your skin or inhale it. DEFINITELY do not ingest it! If it does get on your skin or eyes, wash immediately with water. If it gets ingested, rinse mouth with lots of water. Do not induce vomiting.
