Active Ingredient and Inscalis Mode of Action
Afidopyropen represents a novel pyropene chemical class derived from the fermentation of the fungus Penicillium coprobium.
Classified under IRAC Group 9D, it targets vanilloid receptor-like (TRPV) channels in chordotonal organs, disrupting the insect's senses of hearing, balance, and gravity, which induces immediate and irreversible feeding cessation.
- Active Molecule: Afidopyropen 50 g/L DC (Dispersible Concentrate)
- Inscalis Technology: Chordotonal organ modulator paralyzing the sensory and feeding organs of sucking pests
- Rapid Feeding Cessation: Target sucking insects stop extracting plant sap within minutes of contact, preventing viral transmission
- Acro-Translaminar Movement: Penetrates leaf tissues, moving acropetally to protect newly expanding leaves and shoots
Target Pests and Crop Defense
Sefina is registered across broad-acre fiber crops and high-value vegetables facing destructive homopteran pest attacks.
In cotton, it provides knockdown and long-lasting residual control of all whitefly life stages (nymphs and adults).
- Cotton: Whiteflies (Bemisia tabaci) and jassids (Amrasca biguttula biguttula)
- Chilli: Foliar aphids and whitefly complexes causing honeydew sooty mold
- Brinjal & Tomato: Whiteflies and jassids transmitting geminiviruses
- Extended Protection: Delivers up to 14 to 21 days of persistent sucking pest suppression
Application Guidelines and Pollinator Safety
Sefina offers an outstanding safety profile toward honeybees, predatory ladybird beetles, and lacewings, making it an ideal IPM tool.
Apply at the first appearance of whitefly nymphs using hollow-cone nozzles for thorough canopy penetration.
- Application Rate: Apply at 400 ml per acre using 200 liters of water for complete vegetative coverage
- Timing: Early intervention at threshold levels prevents whitefly population explosions and honeydew mold
- Beneficial Conservation: Highly selective; preserves natural predators that consume remaining pest populations
