Hello, fellow AsianCannabis members
Today, I’m sharing a detailed review of a product that is quite “talked about” among growers in Europe and Australia: Dr. Schimmel S.M.T – Plant & Leaf Wash, which is commonly used for spider mite and russet mite control, as well as leaf cleaning during the vegetative → early flowering stages.
1. What is Dr. Schimmel S.M.T?
It is not a chemical pesticide. S.M.T. is a leaf wash that works through mechanical action:
- Breaks the protective membrane of spider mites
- Blocks spiracles (breathing holes) → mites dehydrate and die
- Washes away eggs and larvae from the leaves
- Cleans dust, honeydew, and light mold from the leaf surface
Biggest Advantage: Zero residue – can be used even during flowering.
2. Benefits from Real-world Testing
- Rapid results at mild to medium levels: Mites clearly reduced after 2 sprays
- Very safe – no leaf burn, no damage to flowers, no chemical odor
- Easy to use – mix with water, spray, wait, wipe
- Leaves are perfectly clean – dust/honeydew fully removed
- Made from plant extracts and organic surfactants
3. Weaknesses to Know Before Use
This is not a “miracle” product. In these situations:
Severe Infestation (heavy webbing, leaf curling)
→ S.M.T cannot fully eliminate it
→ Combination with bio-acaricides, abamectin, or Beauveria bassiana is necessary
Not a Substitute for an IPM Program
It is only a leaf wash, not a systemic pesticide.
Repeat Spraying Required
Every 3 days for 7-10 days → for full effectiveness.
4. Comparison with Competitor: SV Biotech – MiteTech

5. Conclusion
