Active Ingredient Profile and Mode of Action
Propargite belongs to the sulfite ester chemical family (IRAC Group 12C), formulated as an emulsifiable concentrate (57% EC).
It works by inhibiting the mitochondrial ATP synthase enzyme in mite cells, halting the synthesis of adenosine triphosphate (ATP).
Deprived of cellular biochemical energy, exposed mobile mites suffer rapid paralytic knockdown, feeding cessation, and death within hours.
- Formulation: 57 percent Emulsifiable Concentrate (EC)
- Mitochondrial ATPase inhibitor: Rapidly deprives mites of cellular energy
- Active life-stage control: Highly effective against mobile larvae, nymphs, and adult feeding mites
- Vapor action: Mild vapor redistribution helps penetrate dense mite webbing and curled leaf margins
Target Mite Species and Approved Crop Applications
Propargite is registered across commercial tea plantations, chilies, apples, brinjal, and floriculture.
It is internationally recognized as a premier solution for controlling red spider mites, two-spotted spider mites, and yellow mites.
Foliar applications should be initiated when mite scouting reveals active colonies multiplying on lower leaf surfaces.
- Tea: Highly effective against red spider mites (Oligonychus coffeae), pink mites, and purple mites
- Chilies: Suppresses yellow mites (Polyphagotarsonemus latus), reversing leaf curling and stunted shoot growth
- Apple & vegetables: Controls two-spotted spider mites (Tetranychus urticae) beneath dense webbing
Application Guidelines, Canopy Wetting, and Safety
Because mites inhabit lower leaf surfaces beneath protective webbing, spraying requires high water volumes and fine cone nozzles.
Ensure thorough spray coverage of lower leaf surfaces and interior canopy leaves.
Wear standard personal protective equipment during handling and observe label pre-harvest intervals.
- Underside penetration: Direct spray nozzles upward to thoroughly coat leaf undersides and interior foliage
- Water volume: Use sufficient clean water per acre to penetrate dense mite webbing
- Safety apparel: Wear protective clothing, rubber gloves, and an approved dust respirator during mixing

Common questions
What is the active chemical in Omite acaricide?
Omite contains Propargite 57% EC, a contact and residual sulfite ester acaricide.
Does Propargite kill both nymph and adult mites?
Yes, Propargite delivers rapid knockdown and mortality across all active, mobile mite stages including larvae, nymphs, and adults.
Is Propargite systemic inside plant tissues?
No, Propargite works through contact action and mild vapor pressure; thorough canopy coverage is mandatory for complete mite control.
