Bazak - Pymetrozine 29.2% + Dinotefuran 11.7% WDG - ADAMA
Bazak Insecticide | Pymetrozine 29.2% + Dinotefuran 11.7% WDG
A two-active rice insecticide for brown planthopper, with effervescent water-dispersible granules for spray
preparation.
Crop and target: Rice: brown planthopper (Nilaparvata lugens).
Formulation: Effervescent water-dispersible granules for preparation in spray
water.
Before treatment: Confirm the pest, the first application timing and the full
crop-specific label directions.
Why Choose This Product? Key Benefits
-
🌾 Brown-planthopper focus: A rice
insecticide directed at the brown-planthopper problem, rather than an unspecified treatment for every rice pest.
-
💧 Effervescent spray preparation: The
formulation helps granules break up in spray water for easier preparation.
-
🧩 Complementary insect actions: Pymetrozine
affects feeding-related function, while dinotefuran acts through a different nerve-signalling pathway.
-
🎯 Two systemic ingredients: The combination
contains two systemic active ingredients, while still requiring correct label-directed application and coverage.

Pymetrozine 29.2% + Dinotefuran 11.7% WDG |
| Product type |
Insecticide for brown planthopper in rice |
| Formulation |
WDG: water-dispersible granules with effervescent formulation technology |
| IRAC groups |
Pymetrozine: Group 9B, chordotonal organ TRPV channel modulators. Dinotefuran: Group 4A, nicotinic acetylcholine receptor
competitive modulators. |
| Chemical families |
Pyridine azomethine derivative (pymetrozine) and neonicotinoid (dinotefuran) |
How It Works: Mode of Action
-
Disrupts feeding-related function: Pymetrozine affects chordotonal sensory organs involved in insect movement and feeding,
disrupting normal feeding by susceptible planthoppers.
-
Disrupts nerve signalling: Dinotefuran acts at nicotinic acetylcholine receptors, disturbing normal nerve communication through a
separate pathway.
-
Combines complementary effects: The two-active formulation brings together feeding disruption and a different nerve-system effect
against the target pest.
The combination does not guarantee control of resistant populations or repair crop tissue already damaged.
Count both IRAC Groups 9B and 4A when planning other treatments; a brand change alone may repeat the same groups.
Target Crops & Pests

Brown planthopper (Nilaparvata lugens) |
Identify brown planthopper before treatment. Do not transfer this use to stem borers, white-backed planthopper
or another crop.
Dosage & Application Guide
Prepare WDG in spray water and protect the harvest interval
For the rice–brown-planthopper use, the dilution-water guidance is 500 L/ha, approximately 202.34 L/acre. Add
the water-dispersible granules to spray water as the supplied label directs; do not scatter them dry in the field. Confirm the product
rate and first treatment timing before mixing.
Harvest safeguard for rice treated against brown planthopper: allow at least 22 days between the last
application and harvest, and confirm the current supplied label. This waiting period is not a repeat interval, worker re-entry period
or a complete application programme.
How to Apply: Best Practices
-
Identify the hopper: Inspect the rice crop and confirm brown planthopper, rather than treating every hopper or symptom as the same
problem.
-
Confirm the first treatment timing: Obtain the crop-specific label trigger or stage before applying. A claim about tiller vigour
during the reproductive stage is not an application instruction.
-
Measure and disperse: Weigh the label-directed product amount for the measured area. Follow the mixing order and agitation
directions; do not mix with bare hands.
-
Calibrate the equipment: Use the specified water volume with suitable calibrated equipment, following the label’s spray
instructions. Prevent drift and contamination of water sources.
-
Record and reassess: Record the treatment and planned harvest dates, keep the 22-day last-application-to-harvest safeguard, and
monitor pest activity before considering any further treatment.
Frequently Asked Questions
1. Is Bazak a dry-field granular insecticide?
No. WDG means water-dispersible granules. Prepare it in spray water using the supplied label, rather than
using the directions for a field-applied GR product.
2. Which pest does it target?
Brown planthopper in rice. This use is not a blanket recommendation for every rice hopper or borer.
3. Can I choose a dose from the water volume alone?
No. Obtain the crop-specific product rate, first application timing and complete method before treatment.
The water quantity is not a universal concentration or pump recipe.
4. What is the harvest waiting period?
For the rice–brown-planthopper use, leave at least 22 days after the last application before harvesting and
check the current supplied label. Harvest waiting and worker re-entry are different restrictions.
5. Can I mix it or rely on the premix to prevent resistance?
Use a mixture only when both current labels permit the exact products, crop and method. The premix does not
eliminate resistance risk; account for both Groups 9B and 4A in later treatment choices.
Safety & Disclaimer
Before you use it: Read the supplied Indian label and leaflet before opening the pack, and use the
product only for its listed crop and target. Wear the specified protective clothing and equipment. Avoid skin and eye contact and
inhalation; do not eat, drink or smoke while handling the product. Wash thoroughly and change contaminated clothing after
