Crystal Nidan Insecticide - Cartap Hydrochloride 4% GR Granules for Rice & Sugarcane Pests

Crystal Nidan is a granular insecticide containing Cartap Hydrochloride 4% GR, manufactured by Crystal Crop Protection. It belongs to the Nereistoxin analogue chemical group and is designed to control key insect pests in rice and sugarcane crops. The product comes in a free-flowing granule form (1000–500 micron size) that is easy to apply by broadcasting in standing water or soil.

Nidan works through three modes of action — contact, systemic, and stomach poison. When applied to the field, the granules are absorbed by plant roots and move systemically within the plant. Pests that feed on treated plant tissue ingest the active ingredient, which disrupts their nervous system, causing paralysis and death. This triple-action mechanism makes Nidan effective even against pests hiding inside plant stems or leaf folds.

The product is particularly effective against stem borers, leaf folders, and whorl maggots in rice, and early shoot borer in sugarcane. It provides long-lasting residual control, reducing the need for frequent reapplication. Nidan is also considered safe for the environment and compatible with Integrated Pest Management (IPM) programs, as it has minimal impact on non-target organisms when used as directed.

Key Benefits

• Controls stem borer, leaf folder, and whorl maggot in rice effectively
• Triple-action protection — contact, systemic, and stomach poison for complete pest control
• Works well even in flooded paddy fields with standing water
• Long residual activity reduces the number of sprays or applications needed
• Safe for beneficial insects and suitable for Integrated Pest Management (IPM)
• Easy-to-use granular formulation — no mixing, no spray equipment needed
• Provides effective control of early shoot borer in sugarcane as well

How It Works

Cartap Hydrochloride, the active ingredient in Nidan, is a Nereistoxin analogue. It acts as a neuromuscular disruptor by blocking acetylcholine receptors in the insect's nervous system. When pests come into contact with treated plant surfaces or ingest treated plant tissue, the chemical interferes with nerve signal transmission. This causes continuous nerve stimulation, leading to paralysis, loss of coordination, and eventually death of the pest.

Because Nidan has systemic action, the active ingredient is absorbed by plant roots and moves upward through the plant's vascular system. This means even pests that are hidden inside stems (like stem borers) or protected within folded leaves (like leaf folders) are exposed to the insecticide when they feed. The contact action provides immediate control on direct exposure, while the stomach poison effect ensures pests that feed on treated plant parts are also eliminated. This triple-action mechanism makes Nidan highly effective against a range of chewing and boring pests.

Recommended Dosage & Application

Crop	Target Pest	Dosage (per acre)	Application Timing
Rice	Leaf folder, Stem borer, Whorl maggot	7.5–10 kg	At initiation of infestation (15–25 days after sowing)
Sugarcane	Early shoot borer	10–12 kg	30–40 days after planting

Application Method: Broadcast the granules uniformly over the field. For rice, ensure standing water is present in the field during application. After applying, maintain water level for 2–3 days for best results.

When to Use

Apply Nidan at the first signs of pest infestation for best results. In rice, watch for early symptoms such as dead hearts (stem borer), folded leaves (leaf folder), or stunted growth (whorl maggot). The ideal application window is 15–25 days after sowing (DAS) when these pests typically begin to appear. In sugarcane, apply at 30–40 days after planting when early shoot borer activity starts.

For rice, the product works best when there is standing water in the field. Apply and keep the field flooded for 2–3 days after application to allow the granules to dissolve and be absorbed by plant roots. Avoid application just before heavy rainfall or irrigation that may wash away the granules from the target area.

Step by Step Usage Instructions

1. Wear protective gear: Put on gloves, a mask, and long-sleeved clothing before handling the product.
2. Check water level: For rice, ensure the field has standing water (about 2–5 cm depth) before application.
3. Measure the dose: Use the recommended dosage of 7.5–10 kg per acre for rice or 10–12 kg per acre for sugarcane.
4. Broadcast evenly: Spread the granules uniformly across the entire field by hand or using a granule applicator.
5. Maintain water: After application, keep standing water in the rice field for 2–3 days. Do not drain or let the field dry.
6. Monitor the crop: Check for pest control effectiveness after 5–7 days. Reapply only if needed based on pest pressure.

Precautions & Safety

• Wear gloves, mask, and long-sleeved clothing while handling and applying the product
• Avoid direct skin and eye contact — wash thoroughly with soap and water after handling
• Store in a cool, dry place away from food, animal feed, and drinking water
• Keep out of reach of children and pets
• Do not reuse empty packaging — dispose of it safely
• Avoid application near water bodies, ponds, or fish farms
• In case of accidental ingestion, seek immediate medical attention. Treat symptomatically as there is no specific antidote

Compatibility

Nidan is compatible with most commonly used pesticides and fertilizers used in rice and sugarcane farming. However, it is recommended to conduct a small jar test before mixing with any new product. Do not mix with alkaline substances as Cartap Hydrochloride may degrade under high pH conditions.
