How It Works: Mode of Action
Magister uses advanced METI (Mitochondrial Electron Transport Inhibitor) technology to target the pest's energy centers.
- Contact & Translaminar: The spray penetrates the leaf surface, reaching mites hiding on the underside of leaves.
- Energy Blockade: It binds to the mitochondria (Complex I) in the mite's cells, instantly cutting off their energy supply (ATP).
- Immediate Paralysis: Without energy, the mites become paralyzed, stop feeding, and die rapidly.
Note: This unique action also helps control the Tea Mosquito Bug effectively.
