General Information

Astu is a broad-spectrum insecticide formulated with a combination of deltamethrin, a synthetic pyrethroid insecticide, and buprofezin, an insect growth regulator. Deltamethrin acts as a sodium channel modulator, disrupting nerve function in insects, leading to overexcitation, paralysis, and eventually death. Buprofezin inhibits the development of chitin, a key component of insect exoskeletons, preventing molting and leading to the death of immature insects.

Mode of Action

Deltamethrin works by binding to the sodium channels in the insect's nervous system. This binding prevents the normal opening and closing of these channels, leading to a sustained influx of sodium ions into the nerve cells. This influx of sodium ions disrupts the normal electrical balance of the nerve cells, resulting in overexcitation and paralysis of the insect.

Buprofezin interferes with the biosynthesis of chitin, a crucial component of the insect's exoskeleton. Chitin is essential for providing structural support and protection to the insect's body. By inhibiting chitin formation, buprofezin prevents immature insects from molting, a process necessary for their growth and development. This disruption of molting leads to the death of the immature insects.

Target Pests

Astu effectively controls a wide range of biting and sucking insects, including beetles, caterpillars, flies, aphids, whiteflies, and leafhoppers. It is particularly effective against pests that attack the foliage of plants.

Application Timing and Method

Astu can be applied as a foliar spray. Apply the insecticide to ensure thorough coverage of the plant foliage. Start applications when pests are first seen or when damage is observed. Repeat applications as needed, but allow at least 7 days between applications.

The recommended application rate of Astu varies depending on the target pest, crop, and application method. It is important to carefully read and follow all label instructions to ensure effective pest control and minimize potential risks to human health and the environment.

Precautions and Safety

Astu is a moderately toxic pesticide. It is essential to wear personal protective equipment (PPE), including gloves, goggles, and a long-sleeved shirt and pants, when handling and applying the insecticide. Avoid contact with skin and eyes. Wash thoroughly with soap and water after handling Astu.

Environmental Considerations

Deltamethrin and buprofezin are moderately toxic to aquatic organisms. Do not apply Astu near water bodies or where runoff may occur. Dispose of empty containers and unused product according to local regulations.

Conclusion

Astu is a versatile and effective insecticide that can be used to control a wide range of pests in various crops and settings. Its combination of deltamethrin and buprofezin provides rapid knockdown and long-lasting residual control, protecting crops from damage and ensuring yield protection. When used responsibly and with proper safety precautions, Astu can be an integral component of an integrated pest management (IPM) program.

Additional Guidelines for Applying Astu

• Foliar Spraying: Apply Astu as a foliar spray when pests are first seen or when damage is observed. Repeat applications as needed, but allow at least 7 days between applications.

• Integration with IPM Programs: Astu can be effectively integrated with other IPM strategies, such as biological control and cultural practices, to achieve long-term pest control.

• Monitoring and Retreatment: Monitor crops regularly for signs of pest activity. If necessary, reapplication of Astu may be required to maintain effective pest control.

By following these guidelines and consulting with local experts, you can effectively utilize Astu to control pests and protect your crops from damage.
