Crystal Carlos Insecticide - Pymetrozine 50% WG for Brown Plant Hopper Control in Paddy

Crystal Carlos is a powerful and reliable insecticide from Crystal Crop Protection, formulated with Pymetrozine 50% WG (Water Dispersible Granules). It is specifically designed to control Brown Plant Hopper (BPH) in paddy crops, which is one of the most damaging pests for rice farmers. Carlos belongs to the Pyridine azomethines chemical group and works as a feeding blocker, targeting the pest's nervous system to stop it from feeding on the plant.

Once applied, Carlos is absorbed by the plant through its systemic and translaminar action, reaching even hidden feeding sites where pests may be sheltering. It not only kills existing hoppers by starvation but also prevents adult hoppers from laying eggs, which stops future infestations and reduces the chance of hopper resurgence. This makes Carlos a highly effective and long-lasting solution for paddy farmers looking to protect their yield.

Beyond paddy, Crystal Carlos is also effective against other sucking pests like aphids and whiteflies in crops such as chilli, brinjal, groundnut, potato, and citrus. Its eco-friendly profile and compatibility with Integrated Pest Management (IPM) programs make it a smart choice for farmers who want effective pest control without harming beneficial insects or the environment.

Key Benefits

• Immediate feeding stop: Carlos blocks the nervous system of sucking pests, stopping them from feeding within hours and causing them to die of starvation.
• Long-lasting protection: Systemic and translaminar action ensures the chemical reaches all parts of the plant, providing extended control and reducing the need for frequent sprays.
• Prevents hopper resurgence: Inhibits egg-laying in adult hoppers, breaking the pest life cycle and preventing future outbreaks.
• Effective on multiple sucking pests: Works on Brown Plant Hopper, aphids, and whiteflies across paddy and vegetable crops.
• Safe for IPM programs: Minimal impact on beneficial insects and pollinators when used as directed, making it suitable for integrated pest management.
• Cost-effective solution: Longer control periods and reduced resurgence mean fewer sprays and lower overall pest management costs.
• Eco-friendly formulation: Supports sustainable farming with minimal environmental impact when used according to recommendations.

How It Works

Crystal Carlos contains Pymetrozine, a unique active ingredient that belongs to the Pyridine azomethines chemical group. Unlike conventional insecticides that kill pests directly through contact or ingestion toxicity, Pymetrozine works as a feeding blocker. It targets the nervous system of sucking pests, specifically interfering with the neural regulation of feeding behavior.

When a pest like Brown Plant Hopper feeds on a plant treated with Carlos, the active ingredient disrupts its nervous system and causes immediate cessation of feeding. The pest stops sucking plant sap within hours of exposure. Unable to feed, the insect slowly dies of starvation over the next few days. Additionally, Carlos also affects the reproductive system of adult hoppers, reducing or stopping egg-laying altogether. This dual action—immediate feeding block and reproduction inhibition—ensures both quick control of current infestations and long-term prevention of pest resurgence.

Carlos has systemic action, meaning it is absorbed by the plant and moves through its vascular system to all parts, including new growth. It also has translaminar activity, allowing it to move from the upper leaf surface to the lower surface where many sucking pests hide. This ensures comprehensive protection even in hard-to-reach areas of the plant.

When to Use

For best results, apply Crystal Carlos at the first sign of pest infestation. In paddy crops, watch for early symptoms of Brown Plant Hopper damage such as yellowing of leaves, stunted growth, or the presence of hoppers at the base of the plant near the water line. Early application during the vegetative to early reproductive stage gives the best control.

For vegetable crops like chilli, brinjal, and potato, apply during the vegetative growth stage when aphids or whiteflies first appear. On citrus, apply when active pest populations are noticed on new flushes or tender leaves. Avoid spraying during heavy rainfall or strong winds to ensure proper coverage and effectiveness. The product is rainfast shortly after application, meaning light rain after drying will not wash it off.

Step by Step Usage Instructions

1. Prepare the spray solution: Take the recommended quantity of Crystal Carlos (120–200 g depending on crop) and mix it with 200 litres of clean water per acre.
2. Mix thoroughly: Stir the solution well until the granules are fully dispersed and a uniform mixture is formed.
3. Use proper equipment: Fill the solution in a knapsack or power sprayer fitted with a flat-fan nozzle for even and complete coverage.
4. Apply at the right time: Spray early in the morning or late in the evening when pests are most active and temperatures are lower.
5. Cover all plant parts: Ensure thorough coverage, especially the lower parts of the plant and leaf undersides where sucking pests typically hide.
6. Avoid adverse weather: Do not spray during rain, strong winds, or extreme heat to prevent drift and ensure good deposition.
7. Post-application care: Wash spray equipment thoroughly after use. Do not drain leftover solution into water bodies.

Precautions & Safety

• Wear gloves, mask, and protective clothing while mixing and spraying the insecticide.
• Avoid inhalation of dust during mixing and spray mist during application.
• Wash hands and face thoroughly with soap and water after handling the product.
• Store in original packaging in a cool, dry place away from food, feed, and children.
• Prevent spray drift to nearby water bodies, ponds, or non-target crops.
• Do not eat, drink, or smoke while handling or applying the product.
• In case of accidental contact with eyes or skin, rinse immediately with plenty of clean water and seek medical advice if irritation persists.

PHI / REI & Storage

• Pre-Harvest Interval (PHI) for Paddy: 21 days after application.
• Storage: Store in a cool, dry place away from direct sunlight and moisture. Keep the container tightly sealed when not in use.
• Shelf Life: Refer to the product label for expiry date. Use before the mentioned expiry for best results.
