How It Works: Mode of Action
Magister works by targeting the energy center of the mite (Mitochondria). It is classified as a METI (Mitochondrial Electron Transport Inhibitor).
- Contact & Ingestion: The active ingredient, Fenazaquin, enters the pest through direct contact with the spray or when the mite feeds on treated leaves.
- Energy Blockage: It binds to Complex I in the mitochondria, blocking the production of ATP (energy).
- Total Paralysis: Without energy, the mite becomes paralyzed, stops feeding immediately, and dies shortly after. It also prevents eggs from hatching.
This unique mode of action makes it effective even against mites that have developed resistance to other older chemicals.

Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Using too little water will reduce efficacy.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Tea | 400 - 500 ml | 200 Litres | 2.0 - 2.5 ml | 7 Days |
| Chilli & Vegetables | 500 ml | 200 Litres | 2.5 ml | 7 - 10 Days |
| Apple | Based on Tree Volume | High Volume | 0.4 ml (40ml/100L) | 30 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply at the first sign of infestation (when you see 3-5 mites per leaf). Don't wait for webs to form.
- Mixing: Do not mix with highly alkaline products like Bordeaux mixture or Lime Sulphur. Compatible with most common fungicides.
- Coverage: Mites hide on the underside of leaves. Use a high volume of water and a Hollow Cone Nozzle to ensure the spray reaches underneath the foliage.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying near water bodies.
