Heranba Signor Insecticide

Fast-Acting Synthetic Pyrethroid Insecticide for Cotton Bollworm Management

Heranba Signor is a broad-spectrum insecticide containing Permethrin 25% EC. It belongs to the synthetic pyrethroid group and provides rapid contact and stomach action against susceptible insect pests.

Signor acts on the insect nervous system by disrupting normal sodium-channel function. This produces rapid knockdown, paralysis and mortality of susceptible pests. It is recommended for bollworm management in cotton when used at the correct pest stage and label-recommended dose.

Recommended Crop, Pest and Dosage

The approximate per-acre rate is converted from the registered hectare recommendation. Always follow the current Signor product label for the final field dose and spray-water requirement.

Mode of Action

Permethrin acts on voltage-sensitive sodium channels in insect nerve cells. It delays the normal closing of these channels after activation, resulting in repeated nerve impulses and disruption of normal nervous-system function.

Affected insects develop hyperexcitation followed by paralysis and mortality. The contact and stomach activity of Signor supports rapid pest knockdown when susceptible pests receive adequate exposure.

Cotton Bollworm Management

Bollworms can damage cotton squares, flowers and developing bolls. Larval feeding on reproductive plant parts can directly affect crop development and yield potential when infestations are not managed in time.

Apply Signor when field scouting indicates that bollworm populations have reached the recommended treatment threshold. Timely application and thorough crop-canopy coverage are important for effective pest exposure.

How to Use Heranba Signor

1. Monitor the cotton field regularly for bollworm activity.
2. Measure the recommended quantity accurately.
3. Partially fill the spray tank with clean water.
4. Add the required quantity of Signor while maintaining agitation.
5. Add the remaining water and mix thoroughly.
6. Apply uniformly over the cotton crop canopy.
7. Ensure good coverage of leaves, flowers and developing reproductive parts.
8. Use the prepared spray mixture promptly.

Best Time to Apply

Apply Signor when bollworm infestation reaches the recommended economic threshold rather than through unnecessary calendar spraying. Early treatment of an active infestation generally provides better pest management than application after extensive crop damage has occurred.

Spray under suitable weather conditions and avoid application during strong winds, immediately before rainfall or during excessive midday heat.

Application Tips

• Use the registered crop-specific dose.
• Ensure uniform spray coverage throughout the cotton canopy.
• Use properly calibrated spraying equipment.
• Monitor pest populations before and after treatment.
• Avoid unnecessary repeated applications of the same insecticide group.
• Follow all precautions and restrictions printed on the current product label.

Tank-Mix Compatibility

Heranba states that Signor is generally compatible with many commonly used insecticides and fungicides. However, compatibility should always be confirmed before preparing a full tank mixture.

• Avoid strongly alkaline materials.
• Avoid incompatible sulphur-based products.
• Avoid incompatible copper-based fungicides.
• Conduct a small jar test before using an unfamiliar tank mixture.
• Follow the label instructions of every product in the mixture.

Safety Precautions

• Wear gloves, protective clothing, eye protection and a suitable mask while handling and spraying.
• Avoid direct contact with skin and eyes.
• Avoid inhalation of spray mist.
• Do not eat, drink or smoke while mixing or spraying.
• Wash hands and exposed skin thoroughly after use.
