Syngenta Chess is a highly specialized, world-class systemic insecticide engineered specifically to target and eliminate destructive sap-sucking pests. It is widely celebrated by farmers as the ultimate specialist for controlling Brown Plant Hopper (BPH) in paddy crops, effectively preventing catastrophic "hopper burn".
Technical Overview
Active Ingredient: Pymetrozine (50% WG).
Formulation: WG (Water Dispersible Granules) — a dust-free, easy-dissolving granular formulation.
Mode of Action (Chordotonal Organ Modulator): Chess features a unique 3-way systemic and translaminar action. The moment a pest ingests or comes into contact with the chemical, it paralyzes their mouthparts (stylet) and legs.
The "Starvation" Effect: Within 1 hour of application, the pests permanently lose the ability to pierce the plant and suck sap. Although they may remain visible on the plant for 2 to 4 days, they cannot feed, cause no further damage, and ultimately die of starvation.
Key Benefits
Immediate Crop Protection: Halts crop feeding damage inside of an hour, instantly breaking the cycle of yield loss.
Suppresses Reproduction: It stops adult pests from laying further eggs, putting an end to future population spikes.
Halts Disease Transmission: By rapidly blocking the feeding mechanism, it stops hoppers from transmitting devastating viral plant diseases like Grassy Stunt and Ragged Stunt viruses.
IPM Friendly & Safe for Beneficials: It selectively targets sucking pests while remaining highly safe for predatory spiders and beneficial insects that naturally hunt pests.
Excellent Rainfastness: The systemic granules penetrate the leaf rapidly, making the application safe from being washed away by rain just 2 hours after spraying.
Crop-Specific Uses & Dosages
For row crops, dissolve the product and apply uniformly using 150 to 200 Litres of water per acre.
Crop | Target Pests Controlled | Recommended Dosage | Waiting Period (PHI)* |
Paddy (Rice) | Brown Plant Hopper (BPH), White Backed Plant Hopper (WBPH), Green Leaf Hopper (GLH) | 120 grams / acre (0.6 g per Litre) | 19 - 21 Days |
Vegetables | Aphids, Whiteflies | 100 to 120 grams / acre (0.5 to 0.6 g per Litre) | 14 Days |
Cotton | Aphids, Whiteflies, Leafhoppers | 120 grams / acre (0.6 g per Litre) | 14 Days |
Mango | Mango Hoppers | 0.6 grams per Litre of water (varies by tree size) | N/A |
*Note on PHI: The Pre-Harvest Interval (PHI) is the mandatory minimum number of days you must wait between the final spray application and harvesting the crop.
Application Best Practices for Maximum Efficacy
Target the Canopy Base (Crucial for Paddy): Brown Plant Hoppers primarily live and breed at the very bottom of the rice stalks (the culm). Do not just spray the top leaves; direct your spray nozzle downward into the lower canopy base to ensure the chemical reaches the pest zone.
Prophylactic & Early Timing: Apply at the Economic Threshold Level (ETL)—typically when you count 5 to 10 hoppers per hill. Spraying early prevents the population from exploding into "hopper burn".
Aquatic Warning: Pymetrozine is toxic to aquatic life. Avoid using Chess in fields where integrated paddy-fish farming is practiced, and ensure there is no chemical drift into nearby fish ponds.
