CannaCure – Natural Foliar Spray for Pest and Mildew Control (Ready-to-Use or 1L Concentrate)
Best for: Growers wanting integrated pest management without harsh chemicals, from preventative weekly use to active mildew and spider mite treatment
Our thoughts
CannaCure works differently to most plant protection sprays. It forms a protective second skin rather than poisoning pests, which means you can use it regularly without worrying about leaf damage or resistance building up. What sets it apart is the leaf nutrient element — you're protecting your plants and feeding them at the same time. One we recommend a lot for newer growers and anyone running an integrated pest management programme.
CannaCure is CANNA's first plant protection spray, and it does something most other pest control products don't: it combines broad-spectrum pest and mildew control with built-in leaf nutrition. Rather than relying on harsh chemicals, it works by creating a flexible, natural protective layer on leaf surfaces. Pests and mildew spores can't penetrate it to feed or establish, while the plant remains able to breathe normally. Available in ready-to-use 750ml spray format for convenience, or 1 litre concentrate that makes up to 3 litres of spray solution, giving you flexibility depending on your setup size.
How it compares
CannaCure sits in its own category — mechanical barrier protection with dual nutrition benefit.
- Broader pest coverage than insecticidal soaps (effective on spider mites, whitefly, mealybug, scale — not just soft-bodied insects)
- Controls both pests and mildew in one product (most competitors do one or the other)
- Includes leaf nutrition as a standard feature, not an add-on
- Works via physical barrier rather than chemical dehydration, meaning resistance is unlikely to develop
- Safe to use right up to harvest — no harvest interval required
- Non-toxic and environmentally friendly, made from biodegradable materials
If you're comparing foliar spray options, this is the one that does most with one bottle.
Usage guidance
Preventative use (recommended approach)
Spray once weekly as part of your standard routine. This stops pests and mildew from gaining a foothold in the first place. Most growers find this approach far less stressful than fighting active infestations.
Active pest or mildew treatment
If you spot heavy infestations (spider mites, whitefly, mealybug, powdery mildew), spray every three days and repeat after a further three days if needed. Then drop back to weekly preventative spraying.
Application timing
Spray when your grow light has just switched off for the dark cycle — your plant's stomata will still be open, allowing the spray to absorb properly. This also avoids any risk of leaf scorch from intense light hitting wet foliage. Ensure you wet both the top and undersides of all leaves thoroughly.
Dilution (concentrate format)
Mix 330ml of CannaCure concentrate into 1 litre of water. This ratio makes up to 3 litres of ready-to-spray solution from a 1L bottle. Don't prepare the solution more than ten days in advance.
Coverage across growing stages
CannaCure can be used from start of growth through to harvest alongside your normal nutrient feeding. However, we advise caution during heavy flowering to avoid encouraging mould. It's not a root feed — use only as a foliar spray and continue your normal soil or hydroponic feeding plan.
Compatibility
Mix only with water. Do not combine with hydrogen peroxide-based products or any other treatments.

Our take
CannaCure is proper kit for anyone serious about keeping plants healthy without reaching for harsh chemicals. It's not flashy, but it works reliably week in, week out. The combination of pest control and leaf nutrition in one spray makes it smart value — you're not buying separate products to do jobs it does together.
Whether you're new to indoor growing or managing an established setup, this is worth picking up while stock lasts. One you'll use constantly once you get into the rhythm of preventative spraying. Good time to grab it.
