Bazak - Pymetrozine 29.2% + Dinotefuran 11.7% WDG - ADAMA

ADAMA Bazak: Product Overview

ADAMA Bazak is an effervescent water-dispersible granule insecticide containing Pymetrozine 29.2% + Dinotefuran 11.7% WDG. Its verified Indian use is the control of brown plant hopper, or BPH (Nilaparvata lugens), in rice.

Bazak combines two insecticide modes of action: Pymetrozine in IRAC Group 9B and Dinotefuran in IRAC Group 4A. ADAMA presents the product as a preventive or prophylactic shield to be used before BPH pressure escalates. The current sources checked do not provide a universal pest threshold, exact rice growth stage, spray interval or repeat count, so those details must come from the current physical label and qualified local advice.

The verified formulation rate is 500 g/ha in 500 L water/ha, with a 22-day pre-harvest interval. This page intentionally does not convert that label rate into a per-acre, per-litre, tank or pack-coverage claim.

Why Choose Bazak?

• Verified rice-BPH use: the Indian registration decision covers brown plant hopper on rice.
• Complementary modes of action: Pymetrozine and Dinotefuran belong to two distinct IRAC groups.
• Effervescent WDG formulation: ADAMA states that the patented effervescent granule is designed for faster disintegration and easier, more consistent mixing.
• Clear hectare directions: the official major-use table gives both the formulation dose and water volume.
• Resistance-aware positioning: the page identifies both IRAC groups so farmers can avoid treating another Group 9B or 4A product as a different-group rotation.

Technical Specifications

How Bazak Works

1. Pymetrozine - IRAC Group 9B: IRAC classifies Pymetrozine as a chordotonal-organ TRPV-channel modulator in the pyridine azomethine group.
2. Dinotefuran - IRAC Group 4A: IRAC classifies Dinotefuran as a neonicotinoid nicotinic-acetylcholine-receptor competitive modulator.
3. Two target-site groups: the combination brings the two modes of action together in one formulation. It does not guarantee control and does not remove the need for scouting, correct timing, calibrated application and resistance stewardship.

Verified Crop, Pest, Dose, Water, PHI and Timing

PHI = pre-harvest interval. Use the exact hectare directions above. Do not infer a universal per-acre, per-litre, tank or pack-coverage rate from this table.

Application and Resistance Stewardship

• Scout rice fields regularly and identify brown plant hopper correctly before selecting an insecticide program. Follow the current Bazak label and qualified local recommendations for application timing.
• Measure the formulation for the treated hectare and use the verified 500 L water/ha. Use clean, calibrated spray equipment and obtain the coverage required by the current label.
• Follow the pack directions for adding and dispersing the WDG formulation. ADAMA states that its effervescent granules improve disintegration and mixing consistency, but this page does not replace the label's preparation sequence.
• Bazak already contains IRAC Groups 9B and 4A. A Pymetrozine product such as Mihir or a Dinotefuran product such as Senpai shares one of Bazak's groups and is not a fully different-group rotation.
• Where the separate product label, crop, pest and local resistance program permit, rotate to a standalone insecticide from an unrelated IRAC group. Do not make repeated applications based only on the trade name.
• This page makes no tank-mix or simultaneous-use recommendation. Every Related and rotation product below is a standalone option for a separate, label-directed application.

Safety and Environmental Precautions

• Read the current Bazak label and wear all label-specified personal protective equipment. Avoid inhalation, ingestion and contact with skin or eyes.
• The Indian registration review records the formulation as moderately toxic to aquatic organisms and freshwater fish. Keep product, spray and rinsate away from ponds, streams, drains, fish culture and aquaculture areas.
• The registration review also records high toxicity to honeybees with long-lasting effects. Do not apply when bees are actively foraging, and follow every pollinator precaution on the current label.
• Keep the product in its original labelled container, locked away from children, food, feed and animals. Follow the label for first aid, storage, spill handling and container disposal.

Frequently Asked Questions

What is Bazak's verified Indian use?
Bazak is registered for brown plant hopper, Nilaparvata lugens, on rice. This page does not claim cotton, redgram, pulses, white-backed plant hopper, green leafhopper, whitefly, aphids or other crops and pests.

What is the verified Bazak dose?
The formulation rate is 500 g/ha in 500 L water/ha. Do not replace the hectare directions with an unverified per-acre, per-litre or tank rate.

What is the waiting period?
The verified pre-harvest interval is 22 days.

When should Bazak be applied?
ADAMA positions Bazak preventively before BPH pressure escalates. The current sources checked do not state a universal crop stage, threshold, repeat interval or maximum spray count, so follow the current physical label and qualified local advice.

Are Pymetrozine 50% WG and Dinotefuran 20% SG different-group rotations?
No. Pymetrozine 50% WG shares Bazak's IRAC Group 9B, while Dinotefuran 20% SG shares Group 4A. They may be same-role substitutes where their own labels permit, but they are not fully different-group rotations from Bazak.
