One week your paddy field looks fine. The next, round dry patches appear out of nowhere — and by the time you notice, brown plant hopper control in paddy is no longer optional, it's urgent. The brown plant hopper (BPH), Nilaparvata lugens, hides low at the base of the plant sucking sap, quietly weakening tillers until the whole patch collapses into what farmers call "hopper burn." Left unchecked, it can wipe out a healthy-looking field within days. Along with its cousins the white-backed plant hopper and green leaf hopper, BPH multiplies fastest in humid, densely planted, heavily fertilised fields — and it builds resistance quickly if you spray the same chemical again and again. Here are 9 proven ways to fight back and keep hopper burn from spreading in your paddy.
1. Thiamethoxam 75% SG
Thiamethoxam is a systemic neonicotinoid that the plant absorbs through its roots or leaves and carries through its vascular system. Once inside, it disrupts the hopper's nervous system, giving both quick knockdown and extended protection. It works well as an early-stage application when hopper numbers are just starting to build up at the base of the crop.

2. Ethiprole 10.7% + Pymetrozine 40% WG
This combination pairs two different modes of action in one spray. Ethiprole acts on contact to disrupt the hopper's nervous system, while pymetrozine works by stopping the pest from feeding altogether, causing it to starve. Together they give both quick knockdown and long residual protection, and are considered gentle on natural predators like spiders in the field.

3. Fipronil 0.3% GR
Formulated as a granule, this active ingredient is broadcast directly into the standing water of the paddy field rather than sprayed. It moves through the soil and root zone, giving longer-lasting protection in irrigated conditions and reaching hoppers sheltering low on the plant, close to the waterline, where sprays often miss them.

4. Buprofezin 23.10% + Fipronil 3.85% w/w SC
This ready-mix formulation combines an insect growth regulator with a nerve-acting insecticide. Buprofezin stops young hoppers from moulting into adults, while fipronil delivers fast knockdown on the pests already present. The dual action makes it effective against mixed populations of nymphs and adults in one round of spraying.

5. Dinotefuran 70% WG
Dinotefuran is a fast-moving neonicotinoid that is readily taken up by the plant and travels efficiently through leaf tissue, reaching hoppers even where spray coverage is uneven. It offers quick knockdown against brown plant hopper, white-backed plant hopper, and green leaf hopper together, making it a useful choice when more than one hopper species is active in the field.

6. Fipronil 4% + Thiamethoxam 4% w/w SC
This blend brings together a contact-acting phenylpyrazole and a systemic neonicotinoid in a single spray. Fipronil stays active on the leaf surface while thiamethoxam moves inside the plant, so the combination offers both immediate control and inherent, longer-term protection — useful when hoppers are already at damaging levels and a fast response is needed.

7. Fipronil 15% + Flonicamid 15% WDG
Flonicamid works as a selective feeding blocker, making hoppers stop feeding almost immediately, while fipronil adds a strong contact and stomach action for direct kill. This pairing gives farmers both a fast visible reduction in feeding damage and dependable knockdown, and it is considered relatively safe for pollinators and other beneficial insects when used as directed.

8. Buprofezin 25% SC
A dedicated insect growth regulator, buprofezin blocks chitin synthesis, so hopper nymphs are unable to moult into adults and die before they can multiply further. It also suppresses egg-laying in surviving adults. Because it targets growth rather than the nervous system, it is considered soft on beneficial insects and fits well into an integrated pest management approach.

9. Buprofezin 20% + Acephate 50% w/w WP
This combination covers both life stages of the hopper population in one application: acephate, an organophosphate, knocks down adult hoppers quickly through contact and stomach action, while buprofezin prevents the surviving nymphs from developing further. It also helps manage stem borer and leaf folder, which often show up alongside hoppers in the same field
