Brown planthopper (BPH) remains one of the most destructive pests in rice – not only sucking sap and causing hopper burn but also transmitting serious viral diseases such as grassy stunt and ragged stunt, leading to heavy yield loss.
So how can farmers control planthoppers quickly and effectively?
The answer is Fenobucarb – a carbamate insecticide developed and widely used in Japan.
Key Highlights of Fenobucarb:
Rapid Mode of Action: Inhibits cholinesterase in the insect nervous system, causing paralysis and death within hours.
Dual Action: Works by both contact and ingestion – hoppers are killed whether they touch or feed on treated plants.
Broad Efficacy: Effectively controls brown planthopper, green leafhopper, stink bugs, and leaf folders – protecting rice during seedling and tillering stages.
Quick Field Recovery: Reduces hopper burn, limits virus transmission, and helps rice plants recover faster.
Environmentally Friendly: Low residue and rapid degradation in soil and water – safer for the paddy ecosystem.
Recommended Use (Reference):
- Dosage: 0.75 – 1.0 L/ha.
- Apply early when hoppers first appear, targeting areas with high density.
- Rotate with other insecticide classes to delay resistance.
Safety Notes:
- Wear protective clothing during mixing & spraying.
- Avoid spraying near fishponds, beehives, and drinking water sources.
- Respect pre-harvest interval (7–14 days).
