Product details
Sigalit Insecticide | Pymetrozine 50% WG
A systemic and translaminar feeding blocker for brown planthopper in rice, with spray placement directed to
the plant base.
Target: Brown planthopper in rice, not every rice insect or an unrestricted
all-crop treatment.
First treatment: At the beginning of BPH infestation, with thorough canopy coverage
and spray droplets directed to the base of the plants.
Area and harvest limits: Keep 120 g product and 200 L water per acre together, and
allow 19 days from final application to harvest.
Why Choose This Product? Key Benefits
-
🌾 Focused BPH control: Provides a specific
treatment option for brown planthopper in rice, rather than assuming all rice pests are covered.
-
🛑 Feeding-blocking activity: Disrupts
feeding by susceptible planthoppers; immediate visible knockdown is not the only way to judge its action.
-
🍃 Movement within treated plants: Systemic
and translaminar activity helps the active move within plant tissues, including across treated leaves.
-
🐛 Activity on nymphs and adults: Affected
immature and adult BPH stop feeding and die through starvation; the product also suppresses egg laying.

How It Works: Mode of Action
-
The active reaches susceptible BPH: Contact and ingestion activity, together with systemic and translaminar movement, contribute to
delivery of the active to the pest.
-
Sensory control is disrupted: Pymetrozine modulates TRPV channels in chordotonal organs, sensory structures involved in
coordination and feeding.
-
Feeding stops and starvation follows: Affected BPH lose their normal ability to feed. Nymphs and adults may remain visible before
mortality occurs, so do not add an unsupported early repeat.
These are steps in one IRAC Group 9B mode of action, not three separate groups. Changing to another pymetrozine
brand does not change that mode of action. Neither plant movement nor feeding inhibition removes the need for correct placement and
resistance management.
Target Crops & Pests

Use only the rice–brown planthopper pairing permitted on the supplied Indian Sigalit pack. Do not extend this
row to other hoppers, rice insects or crops without their own permitted directions.

Use the row only when the supplied current Sigalit pack permits the exact crop and target and agrees with the
complete directions. Measure the treated area and keep its product amount, water volume, placement and first-treatment stage together.
These are acre-based quantities, not a per-litre or tank recipe. The pre-harvest interval runs from final application to harvest;
worker re-entry and repeat-treatment intervals are separate.
Use well-maintained spray equipment and suitable nozzles to deliver the specified amount to the target. Ensure
thorough crop-canopy coverage and direct droplets to the plant base. Do not replace this placement instruction with a general spray
over the top of the canopy.
No automatic repeat, extra-adjuvant or tank-mix programme is given. Follow the applicable current-pack
restrictions and assess the pest rather than treating visible survivors as a reason for an early extra application.
How to Apply: Best Practices
-
Confirm the crop and pest: Identify brown planthopper in rice and check the exact 50% WG product and permitted use on the current
pack.
-
Measure area, product and water: Use 120 g product and 200 L water for each acre treated. Weigh accurately and calibrate equipment
to the measured area, not to an assumed number of tank loads.
-
Treat at the beginning of infestation: Apply at the beginning of BPH infestation. Thoroughly cover the crop canopy and direct
droplets to the base of the rice plants.
-
Maintain equipment and prevent drift: Use well-maintained spray equipment and proper nozzles for target delivery. Follow the pack’s
mixing, weather and operator-protection directions. Avoid drift and runoff.
-
Check mixtures and further treatment: Mix with another product only when both current labels expressly permit the proposed
combination for the crop and use. Physical compatibility alone is not permission to mix. Do not automatically add an adjuvant, fertilizer
or another insecticide, or repeat sooner because immediate knockdown is absent.
-
Record and observe waiting periods: Record the field, pest, area, quantity and application date. Allow 19 days from final
application to harvest and observe worker-entry and any further-treatment restrictions separately.
Frequently Asked Questions
1. What pest is this rice programme for?
Brown planthopper. It is not a general recommendation for all rice hoppers, caterpillars or other crop
pests.
2. How much product and water are used per acre?
The rice–BPH row uses 120 g product with 200 L water per acre, as a crop spray at the beginning of
infestation. Keep the full stage, placement and 19-day harvest restriction together and check the supplied current pack.
3. Where should the spray reach?
Cover the crop canopy thoroughly and direct spray droplets to the base of the rice plants. Use
well-maintained equipment and appropriate nozzles so the treatment reaches the target rather than relying only on top-canopy
wetting.
4. Why might BPH remain visible after treatment?
Sigalit blocks feeding and mortality follows starvation rather than necessarily immediate knockdown. Monitor
the pest and follow current-pack directions; do not invent an early repeat or a fixed guaranteed kill time.
5. Can the harvest interval be used as a repeat or entry interval?
No. The 19-day pre-harvest interval runs from the final application to harvest. Re-entry, further treatment
and mixture restrictions are separate. The area quantities also do not create an independently labelled per-litre or pump dose.
