What is Magister Insecticide?
Magister insecticide is a selective acaricide and insecticide primarily used to control mites such as red spider mites, yellow mites, and other harmful pests. Its active ingredient is generally Fenazaquin 10% EC, which works by disrupting the energy production system of mites, leading to their rapid death.
Magister is mainly applied in crops like cotton, chilli, tea, brinjal, tomato, apple, grapes, and ornamental plants. It is especially effective at different life stages of mites, including nymphs and adults.

How Magister Insecticide Works
Magister insecticide works through contact and stomach action. Once the pest comes into contact with the sprayed surface or feeds on treated plant parts, the chemical interferes with mitochondrial respiration. This results in reduced energy production, paralysis, and eventual death of the pest.
One of the key advantages of Magister is its long residual activity, which continues to protect crops for several days after application. This helps reduce the frequency of spraying and lowers overall pest management costs.
