Chess is a unique insecticide from Syngenta specifically designed for controlling rice planthoppers, particularly the Brown Planthopper (BPH).1 Its active ingredient is Pymetrozine 50% WG (water dispersible granules), which offers a novel mode of action for effective and sustainable pest management.2
Key Features and Benefits:
Unique mode of action: Pymetrozine belongs to the pyridine azomethine group (IRAC Group 9B) and works by disrupting the feeding behavior of planthoppers.3 It causes rapid cessation of feeding, leading to starvation and eventual death.4
Systemic action: Absorbed by the plant and translocated both upwards and downwards, providing protection throughout the plant.5
Fast action: Quickly stops planthoppers from feeding, minimizing damage to the rice crop.6
Long-lasting residual control: Offers extended protection against planthoppers, reducing the need for frequent applications.7
Anti-oviposition effect: Reduces egg-laying by planthoppers, further suppressing the pest population.8
Selective action: Generally safe for beneficial insects like natural enemies, making it suitable for Integrated Pest Management (IPM) programs.9
Excellent rain fastness: Resists wash-off by rain, ensuring continued protection.10
Target Crops and Pests:
Rice (Paddy): Primarily used for controlling Brown Planthopper (BPH) and other planthoppers.11
Other crops: Also effective against aphids and whiteflies in some crops.12
Recommended Dosage:
The recommended dosage for Chess is generally 120 grams per acre.13 However, it's crucial to consult the product label or a qualified agricultural expert for specific recommendations based on the pest infestation and growth stage of the rice crop.
Application Method:
Foliar spray: Apply Chess as a foliar spray, ensuring thorough coverage of the rice plants.14
Prophylactic usage: For optimal control of BPH, prophylactic applications of Chess are recommended.15
Apply at the first sign of infestation or as a preventive measure.16
Repeat applications as needed, based on pest pressure and recommendations.
Safety Precautions:
Always wear protective clothing, including gloves, masks, and eye protection, when handling and applying Chess.
Avoid contact with skin and eyes.
Do not inhale the spray mist.
Keep out of reach of children and animals.
Store in a cool, dry place away from direct sunlight and heat.
