Mammoth® CannControl

After our mammoth multi-year search for a high-caliber plant-based fungicide and insecticide, the thyme has finally come! For use on cannabis and other annuals; from the makers of Mammoth P. Lab and greenhouse tests show CannControl to prevent and eliminate powdery mildew, Botrytis cinerea (gray mold), mites, aphids, whiteflies, thrips and fungus gnats.

The active ingredients—15% thyme oil, 55% corn oil—are safe to handle, and the product can be used weekly through the season as a foliar spray or root drench to keep fungal and insect pests at bay. As a preventive, use 1 fl oz per gal water. To address an active infestation or infection, increase the mix rate to 3 fl oz per gal water. We recommend first testing your solution on a few leaves and observing for 2 days; discontinue use if you see signs of burning. Do not use it on newly planted cuttings or on plants stressed by drought, and avoid application when temp exceeds 90°. Stop applications 2–3 weeks prior to harvesting your crop to ensure all the oil has broken down. As with any horticultural oil, do not apply this product when bees are actively foraging, and avoid applying within 30 days of sulfur-based fungicides. Exempt from EPA registration. Please see pesticide label here. 8712B is a NEW! 250ml size for smaller operations.

Note to certified organic growers: Restricted—may be used if preventative, mechanical, and physical management practices provided for at CFR 205.206(a)-(d) are insufficient to prevent or control crop pests, weeds, and diseases; the operator must document conditions for using the substance in their organic system plan.

Is that pesticide registered in your state?

Each state treats potentially dangerous items differently. Like alcohol and open-carry laws, pesticide registrations are different everywhere. We cannot ship a pesticide to a state where it is not registered.

Before buying or using any pest- or disease-control product, be sure it is registered for use in your state and, if you are a commercial grower, registered for commercial production.

Purdue University has a searchable database of information for most states. You can look up products by name, registration number or active ingredient. Contact information is provided for states that don’t participate in the website.

USDA NOP rule concerning disease and pest control
Caution certified-organic growers:

Before using any of these products for pest or disease control, you must have followed the National Organic Program rule 205.206(e). A product being labeled here as allowed is not sufficient to meet standards for organic certification.
