Active ingredient and furanicotinyl mode of action
Dinotefuran acts as a competitive agonist of the nicotinic acetylcholine receptor (nAChR, IRAC Group 4A). Its unique tetrahydrofuran ring structure gives it high water solubility and swift acropetal translocation through plant xylem, resulting in rapid insect paralysis, immediate feeding cessation within hours, and mortality.
- Active constituent: Dinotefuran 20% SG (soluble granules)
- Chemical family: Furanicotinyl / Neonicotinoid (IRAC Group 4A)
- Systemic mobility: Rapid xylem uptake and translaminar penetration protecting new vegetative flushes
Target crops and major sucking pest complexes
- Paddy (rice): Brown plant hopper (Nilaparvata lugens) and white-backed plant hopper (Sogatella furcifera).
- Cotton: Whiteflies (Bemisia tabaci), jassids, and aphids.
- Vegetables and chili: Thrips and whitefly nymphs.
Application technique in paddy fields
For controlling brown plant hopper in paddy, direct the spray nozzle toward the base of rice hills where hopper colonies congregate on lower tillers. The recommended dose is typically 80 to 100 grams per acre in 200 litres of water. Avoid spraying during active daylight bee foraging hours, and adhere to CIBRC registered pre-harvest intervals.

Common questions
What is the active ingredient in Osheen insecticide?
Osheen contains dinotefuran 20% SG, a third-generation furanicotinyl systemic insecticide.
How should Osheen be sprayed to manage brown plant hopper (BPH)?
Spray should be directed toward the lower base of rice tillers where BPH colonies feed and multiply.
Does Osheen possess translaminar activity?
Yes, its high systemic and translaminar activity allows it to penetrate leaves quickly to reach pests feeding on the underside.
