Why Choose This Product? Key Benefits
-
🌾Rice-hopper focus: The manufacturer lists both brown and white-backed planthoppers in rice.
-
🍽️Feeding disruption: Interferes with the pest’s ability to continue feeding on the crop.
-
↗️Systemic movement: The active ingredient moves within the plant.
-
🍃Through-leaf movement: Can move through a treated leaf as well as acting through contact.
-
🔬Distinct resistance group: Pymetrozine belongs to IRAC Group 9B, useful to identify when planning a rotation.

How It Works: Mode of Action
Astra is a selective feeding blocker with contact and systemic action. Its active ingredient affects sensory structures that help insects coordinate normal behaviour.
-
Treatment reaches the pest: Contact, systemic and through-leaf activity help bring pymetrozine into contact with susceptible feeding pests.
-
Normal sensing is disrupted: Pymetrozine affects channels in the insect’s sensory organs that help regulate movement and feeding.
-
Feeding is interrupted: The pest’s feeding behaviour is disrupted. Use the label’s assessment and repeat-treatment directions rather than assuming an immediate visible knockdown.
Do not assume that resistance cannot develop. Rotate suitable modes of action within the crop’s recommended pest-management programme.
Target Crops & Pests
Coromandel lists these rice pests for Astra. Check the supplied label for the complete directions for each target.
| Crop |
Target Pest(s) |

| Rice |

Both pests are included in the manufacturer’s product scope, but each requires its own complete current label programme. Do not transfer BPH carrier or harvest directions to WBPH.
Dosage & Application Guide
Numerical application programmes are withheld because the available manufacturer information and separate formulation references do not establish complete current Astra directions with matching treatment conditions, method, carrier and harvest requirements. Verify these together on the supplied pack before use.
Complete Programme Verification
Keep brown planthopper and white-backed planthopper as distinct target programmes. Generic formulation references for BPH do not establish the current branded WBPH carrier or harvest directions.
The manufacturer booklet limits the authority of its recommendations and is not the supplied current label. Do not combine product quantities with water or waiting periods from separate references. A missing waiting period does not mean immediate harvest is permitted.
No separate per-litre or tank dose is provided. Confirm the application method, mixing sequence, crop-stage timing, repeat interval, maximum sprays, rainfast time and re-entry interval on the supplied label.
How to Apply: Best Practices
-
Identify the hopper: Confirm whether the target is BPH or WBPH, then use the matching directions on the supplied Astra label.
-
Follow the stated application: Use the pack’s equipment, mixing sequence, coverage and crop-stage instructions. The listed crop and target scope alone is not a spray programme.
-
Check mixtures: Avoid highly acidic or alkaline mixtures. Do not assume every insecticide or fungicide can be added; follow the applicable labels.
-
Plan harvest and reassessment: Confirm the target-specific waiting period and re-entry instructions. Assess pest activity as the label directs before deciding whether another treatment is needed.
Frequently Asked Questions
What does Astra contain?
Astra contains pymetrozine 50% in water-dispersible granules (WG).
Does Astra cover both BPH and WBPH?
Coromandel lists brown planthopper and white-backed planthopper in rice. Confirm that the supplied label includes your intended target and complete directions.
Is Astra systemic?
Yes. The manufacturer describes contact and systemic action, together with movement through treated leaves.
Can I transfer the BPH harvest interval to WBPH?
Do not assume that. Confirm the exact current Astra label’s waiting period for each target separately before treatment and harvesting.
Should I spray again if insects do not fall immediately?
Do not automatically repeat the treatment. Astra works by disrupting feeding. Follow the label’s assessment, repeat-interval and maximum-application directions.
