Active botanical profile and ecological mode of action
- Formulation basis: Proprietary blend of plant extracts, herbal alkaloids, and fatty acid esters formulated for agricultural pest protection.
- Multi-modal action: Functions through contact disruption of insect spiracles, digestive tract inhibition, and powerful repellent signaling.
- Anti-feedant properties: Treated crop surfaces deter sucking insects from feeding, disrupting their normal reproductive and oviposition cycles.
- Residue-free: Leaves zero hazardous synthetic residues, making it ideal for residue-conscious export horticulture and organic farming.
Target insect pests and crop recommendations
- Chilli: Controls devastating thrips (Scirtothrips dorsalis), yellow mites, and aphid colonies causing leaf curl.
- Cotton: Manages whiteflies, jassids, and early-stage thrips without flaring secondary pests.
- Vegetables: Protects tomato, brinjal, capsicum, and cucurbits against sucking insects and whitefly-borne viral vectors.
- Horticulture: Effective in pomegranate, papaya, and citrus against scale insects, mealybugs, and mites.
- Beneficial safety: Safe for honeybees, ladybird beetles, chrysoperla, and other predatory natural enemies when applied as recommended.
Application timing, spray calibration, and storage
- Spraying schedule: Apply at the first symptom of sucking pest build-up, repeating at 7 to 10-day intervals depending on pest pressure.
- Spray quality: Use 150 to 200 litres of water per acre with fine hollow-cone nozzles for complete foliar coverage, targeting leaf undersides.
- Tank mixing: Avoid mixing with strongly alkaline agrochemicals or copper-based fungicides.
- Storage: Store in the original sealed bottle in a cool, shaded environment away from direct heat and sunlight.
