Chemical profile and multi-action insecticidal properties
Profenofos belongs to the organothiophosphate subgroup within the organophosphorus class (IRAC Group 1B).
Key technical properties:
- Active ingredient: Profenofos 50% Emulsifiable Concentrate (EC).
- Acetylcholinesterase inhibition: Disrupts nerve transmission across synaptic junctions, leading to hyperexcitation, paralysis, and death.
- Translaminar mobility: Moves efficiently across leaf blades to reach sheltered larvae and mites feeding on the underside of foliage.
- Ovicidal action: Kills insect eggs on contact, preventing pest larvae from emerging and initiating feeding damage.
- Acaricidal activity: Controls spider mites simultaneously, reducing the need for specialized standalone miticides.
Approved crops and key target insect pests
Profenofos is registered by the Central Insecticides Board for multiple field crops:
Primary target spectrum:
- Cotton: American bollworm (Helicoverpa armigera), spotted bollworm, pink bollworm, and cotton whitefly nymphs.
- Soybean: Semilooper, tobacco caterpillar (Spodoptera litura), and girdle beetle.
- Pulses (Pigeon pea, Chickpea): Pod borer complex and pod bug (Clavigralla).
- Chilli: Mites, thrips, and fruit borer infestations.
Safe handling protocols and resistance management
Dilute according to CIBRC-approved product label rates (typically 400 to 600 ml per acre in 200 litres of water). Rotate Profenofos with insecticides from alternate mode-of-action groups (such as diamides or avermectins) to delay pest resistance. Applicators must wear nitrile gloves, protective masks, and rubber boots, avoiding spraying during intense midday heat.
