Chemical Class and Complex II Mitochondrial Inhibition
Cyenopyrafen belongs to the pyrazole carboxamide chemical class and acts as a Mitochondrial Complex II Electron Transport Inhibitor (IRAC Group 25). It binds specifically to the succinate dehydrogenase complex within mite mitochondria.
This metabolic blockade shuts down cellular respiration, depriving mite cells of energy. It exhibits fast contact action, halting feeding within hours of foliar deposition and causing complete mortality within 24 to 48 hours.
- IRAC Group 25 Mode of Action: Inhibits Complex II respiration without cross-resistance to legacy organophosphates or avermectins.
- All-Stage Acaricidal Control: Active against mite eggs, six-legged larvae, protonymphs, deutonymphs, and reproductive adults.
- Suspension Concentrate (SC): High-concentration water-based formulation that adheres firmly to leaf cuticles.
Target Mite Species and High-Value Crops
Phytophagous mites cause severe economic damage in high-value horticulture crops, tea plantations, and protected polyhouses during warm, dry spells. Feeding damages chlorophyll cells, causing chlorotic mottling, leaf bronzing, and premature defoliation.
Kunoichi is officially registered under CIBRC standards for controlling red spider mites (Tetranychus urticae and Oligonychus coffeae), two-spotted spider mites, and yellow mites across crops such as tea, chilli, apple, and brinjal.
- Tea Plantation Management: Rapidly knocks down red spider mites and scarlet mites on tender harvestable tea bushes.
- Chilli & Solanaceous Vegetables: Controls yellow and red mites that trigger severe downward leaf cupping and flower abortion.
- Polyhouse Floriculture: Controls resistant spider mite populations on greenhouse roses and gerberas.
Foliar Spray Technique and Resistance Management
Because mites inhabit the undersides of leaves and spin protective silken webs, thorough spray coverage is essential. Use hollow cone nozzles on knapsack sprayers, directing spray jets into the lower and middle plant canopy.
To delay resistance development, rotate Kunoichi with acaricides of distinct modes of action (such as Spiromesifen, Fenazaquin, or wettable sulphur) within the same growing season.
- Targeted Underside Spray: Ensure water volume is sufficient to thoroughly coat lower leaf surfaces.
- Rotation Strategy: Avoid more than two sequential applications of Complex II inhibitors in a single season.
- Beneficial Insects: Demonstrates safety toward beneficial predatory insects like ladybird beetles and honeybees when applied per label.

Common questions
What is the technical ingredient in Kunoichi miticide?
Kunoichi contains Cyenopyrafen 30% SC (Suspension Concentrate), a specialized acaricide from the pyrazole chemical group.
Does Kunoichi kill mite eggs as well as adults?
Yes, Cyenopyrafen possesses strong ovicidal, larvicidal, and adulticidal activity, controlling all life stages of phytophagous mites.
How does Kunoichi halt mite respiration?
It acts as an IRAC Group 25 Mitochondrial Complex II inhibitor, stopping electron transport and cellular energy generation.
