Cartap 50% SP Insecticide (Cartap Hydrochloride 50% SP) for Rice Stem Borer Control

Cartap 50% SP is a modern, biorational-type insecticide derived from a synthetic analogue of a natural marine worm toxin. It is formulated as a water-soluble powder (SP), which dissolves quickly in water to form a uniform spray solution for field application.

Key positioning:

• Specialised for rice stem borer management in paddy rice
• Strong stomach poison with additional contact, anti-feeding and ovicidal effects
• Fits high-humidity, irrigated rice systems typical in Asia, Africa and other rice-growing regions
• Suitable for importers and distributors seeking a cost-effective, field-proven rice insecticide

What Is Cartap 50% SP?

1 Active Ingredient & Formulation

• Active ingredient: Cartap hydrochloride – 50% w/w
• Formulation type: SP – Water-Soluble Powder

The SP formulation offers:

• Easy dissolution in water for spray applications
• Clean handling with no oil-based solvent odour
• Convenient storage and transport, with lower leakage risk compared to liquid EC formulations

2 Why SP Formulation Works Well in Rice

For rice farmers, especially in developing markets, SP formulations provide:

• Compatibility with common knapsack or power sprayers
• Ease of use for smallholder and large-scale operations
• Reduced risk of staining and odour compared to certain liquid products
• Efficient packaging, suitable for both wholesale and retail channels

Mode of Action

1 How Cartap Controls Insects

Cartap is a neurotoxic insecticide with a unique mode of action compared to many conventional products:

• It works primarily through stomach poisoning when insects feed on treated plant tissues.
• It blocks nerve impulse transmission at the central nervous system level, leading to paralysis and death.
• In addition to strong stomach action, it also exhibits:
  • Contact activity
  • Anti-feeding (feeding inhibition)
  • Ovicidal effects on certain pest stages

2 Benefits of This Mode of Action

• Effective against borer-type pests, which ingest treated plant tissue as they feed or before boring into stems.
• Fast knock-down of active larvae, reducing damage to tillers, stems and panicles.
• Longer residual effect, providing protection over a meaningful period when applied at the correct growth stage.
• A useful alternative molecule to rotate with other insecticide groups in resistance management programmes.

Target Pests & Crops

1 Primary Target Pest

• Rice Stem Borer (including second-generation borers in many markets)
  • Cartap is particularly valued for controlling stem borer larvae at early stages.
  • When applied at the proper timing, it helps reduce dead-hearts and whiteheads caused by stem feeding.

2 Main Crop

• Paddy rice

In many rice-growing countries, Cartap 50% SP is used as a standard option against stem borers in irrigated and rainfed rice systems. Use on any other crop or pest should strictly follow local registration and label approvals.

Usage & Application Guidelines

The following is a general overview for professional users. Exact dose, spray volume, interval and number of applications must always follow the approved product label and local regulations in your country.

1 Application Timing

For optimal performance against rice stem borers:

• Apply when egg hatch is at peak and early instar larvae are present, before they bore deep into the stems.
• Monitor fields and follow local agronomic guidance on threshold levels and timing.
• Applications can be scheduled according to pest pressure, typically with an interval as indicated on the label.

2 Water Management in Paddy Fields

• After spraying, maintaining a shallow water layer in the paddy field for several days can support effective coverage and uptake.
• Avoid draining treated water directly into natural water bodies, irrigation channels or aquaculture ponds.

3 Application Conditions to Avoid

• Do not spray under strong wind conditions, which increase drift and uneven coverage.
• Avoid application if rainfall is expected shortly after spraying, as wash-off can reduce efficacy.
• Respect the pre-harvest interval (PHI) as indicated on the label; typical PHI for rice is around 21 days, but you must follow local registered values.

Key Advantages for Distributors & Growers

1 Performance Benefits

• High efficacy on rice stem borers
  Cartap targets a major yield-threatening pest in rice and offers reliable control when used at the correct timing.
• Strong stomach action with long residual effect
  Larvae feeding on treated plant tissues rapidly stop feeding, become paralysed and die, while the residual activity provides extended protection.
• Good fit for intensive rice systems
  Especially suitable for rice regions with multiple borer generations per season.

2 Operational & Commercial Benefits

• Water-soluble powder – easy to transport, store and handle
• Low odour compared with certain liquid insecticides, more acceptable for operators
• Cost-effective solution for large acreages
• Versatile for both wholesale and retail channels through flexible packaging sizes

Safety & Environmental Information

This product is intended for professional use only. It must be handled and applied by trained personnel aware of pesticide safety standards.

1 Operator Safety

• Avoid inhaling dust or spray mist.
• Avoid contact with skin, eyes and clothing.
• During mixing and spraying, wear appropriate personal protective equipment (PPE):
  • Protective clothing with long sleeves
  • Chemical-resistant gloves
  • Face mask/respirator and eye protection
• Do not eat, drink or smoke while handling the product or during spraying.
• After work, wash hands, face and exposed skin thoroughly and change contaminated clothing.

If symptoms of poisoning occur (such as dizziness, nausea, headache or breathing discomfort), stop work immediately and seek medical advice. Treatment should follow local guidelines for Cartap exposure and be supervised by medical professionals.

2 Environmental Safety

• Toxic to honey bees and silkworms.
  • Do not apply on flowering crops visited by bees.
  • Do not use near silkworm houses or mulberry plantations.
• Use restrictions in aquatic-related systems:
  • Not recommended in rice fields where fish, shrimp or crabs are raised together with rice.
  • Do not wash equipment or dispose of leftover spray in ponds, rivers, canals or other water bodies.
• Follow local environmental regulations for use near sensitive areas, beneficial insect release zones, and protected habitats.

3 Storage & Disposal

• Store in a cool, dry, well-ventilated and rain-proof place.
• Keep away from heat sources, open flame and direct sunlight.
• Do not store together with food, feed, drink or other household goods.
• Keep out of reach of children and unauthorised persons; keep locked when not in use.

Frequently Asked Questions (FAQ)

Q1. What is Cartap 50% SP mainly used for?
Cartap 50% SP is mainly used for controlling rice stem borers in paddy fields. It is especially effective when applied at egg hatching and early larval stages to prevent larvae from damaging rice stems and panicles.

Q2. How does Cartap differ from other common rice insecticides?
Cartap has a distinct mode of action as a strong stomach poison with additional contact, anti-feeding and ovicidal activity. It is particularly suitable for borer-type pests and can be a valuable rotation partner with other insecticide groups in resistance management programmes.

Q3. Can Cartap 50% SP be used in rice fields with fish or shrimp?
In general, Cartap is not recommended for rice–fish or rice–shrimp integrated systems. You should always follow local label restrictions and avoid contaminating aquaculture water bodies.

Q4. Can I tank-mix Cartap 50% SP with other pesticides or fertilisers?
Tank-mixing should be approached with caution. Avoid mixing with strongly alkaline products. Always consult the local label and conduct a small compatibility test before preparing a full tank mix. When in doubt, use Cartap 50% SP alone in the spray tank.

Q5. What personal protective equipment (PPE) is required when using Cartap 50% SP?
Operators should wear protective clothing, chemical-resistant gloves, a suitable mask/respirator and eye protection during mixing and spraying. After work, they should wash thoroughly and change contaminated clothing.
