Recommended Crop & Target Pests

These rates correspond to approximately 7.5 kg per acre for stem borer and approximately 7.5–10 kg per acre for leaf folder and whorl maggot for the registered Cartap Hydrochloride 4% GR technical use.

Because the exact current Paidavaar Calwar label could not be independently located online, always use the dose printed on the physical Calwar product label as the final authority.

Mode of Action

Cartap Hydrochloride – IRAC Group 14: Cartap is a nereistoxin analogue that acts as a nicotinic acetylcholine receptor channel blocker. It interferes with normal transmission of nerve impulses in susceptible insects.

Affected insects show reduced feeding activity followed by paralysis and control. Cartap Hydrochloride 4% GR also provides systemic activity after application to the crop environment.

Paidavaar Calwar for Paddy Stem Borer

Stem borer is an important insect pest of paddy that can damage tillers and affect crop productivity. Cartap Hydrochloride 4% GR is registered for stem borer management in rice and can be broadcast uniformly according to label recommendations.

Early detection and timely application are important because severe stem damage cannot be reversed after it has already occurred.

Paidavaar Calwar for Leaf Folder

Rice leaf folder larvae fold crop leaves and feed within the folded portion, reducing healthy photosynthetic leaf area. Cartap Hydrochloride 4% GR is used for management of leaf folder when applied according to the registered recommendation.

Granular Broadcasting

Calwar is a granular formulation and should be applied by broadcasting the granules uniformly in the paddy field. It is not a foliar spray formulation and should not be converted into a per-litre spray dose.

Maintain suitable paddy-field conditions according to the product label so the granules are distributed effectively around the crop.

How to Use Paidavaar Calwar Insecticide

1. Identify the target pest correctly before application.
2. Measure the required quantity according to the crop area and current Calwar label.
3. Broadcast the granules uniformly throughout the paddy field.
4. Avoid concentrating excessive granules in a small area.
5. Maintain field water conditions according to the current product-label recommendation.
6. Monitor the crop after application to assess pest activity.
7. Repeat application only when permitted by the current product label and pest-management recommendation.

Best Time to Apply

Apply Calwar during the early stage of registered pest infestation, before severe crop damage develops. Regular field scouting can help identify stem borer and leaf folder activity at an appropriate treatment stage.

Application Tips

• Broadcast granules uniformly throughout the treated area.
• Do not dissolve the GR formulation for foliar spraying.
• Apply only on crops and pests permitted by the current label.
• Maintain suitable field moisture or water conditions according to label directions.
• Avoid excessive application beyond the recommended rate.
• Use gloves and suitable protective equipment when handling granules.
• Rotate insecticide modes of action where repeated pest treatments are required.

Resistance Management

Cartap Hydrochloride belongs to IRAC Group 14. Repeated use of the same insecticide mode of action can increase resistance-selection pressure in pest populations.

Where additional insecticide treatments are required, rotate with appropriate registered insecticides from other effective IRAC groups and integrate cultural, biological and mechanical pest-management practices wherever practical.

Safety Precautions

• Read the complete physical product label and accompanying leaflet before use.
• Wear suitable gloves, protective clothing, footwear and other recommended PPE while broadcasting.
• Avoid direct contact with skin, eyes and mouth.
• Do not eat, drink or smoke while handling the insecticide.
• Avoid contamination of ponds, streams and drinking-water sources.
• Keep children and animals away from the product and treated field according to label instructions.
• Wash hands and exposed skin thoroughly after application.
• Store securely away from food, feed and children.
