General Information

Fencro is a broad-spectrum insecticide formulated with a synergistic combination of diafenthiuron and bifenthrin. Diafenthiuron, a benzoylurea insecticide, acts as a chitin synthesis inhibitor, disrupting the formation of chitin, a crucial component of the insect exoskeleton. This disruption of chitin formation prevents molting, a process necessary for insect growth and development, leading to the death of immature insects. Bifenthrin, a synthetic pyrethroid insecticide, acts as a sodium channel modulator, further disrupting nerve function in insects and providing rapid knockdown effect.

Mode of Action

Diafenthiuron works by interfering with the biosynthesis of chitin, a key component of the insect exoskeleton. Chitin is essential for providing structural support and protection to the insect's body. By inhibiting chitin formation, diafenthiuron 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.

Bifenthrin works by binding to sodium channels in the insect's nervous system, preventing the normal opening and closing of these channels. This disruption of sodium channel function leads to a sustained influx of sodium ions into the nerve cells, resulting in overexcitation and paralysis of the insect.

Target Pests

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

Application Timing and Method

Fencro can be applied as a foliar spray or soil drench. For foliar spraying, 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 10 days between applications.

For soil drenching, apply the insecticide around the base of the plant and allow it to soak into the root zone. This method is particularly effective against pests that attack the roots or lower stems. Repeat applications as needed, but allow at least 14 days between applications.

The recommended application rate of Fencro 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

Fencro 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 Fencro.

Environmental Considerations

Diafenthiuron is moderately to highly toxic to aquatic organisms. Do not apply Fencro near water bodies or where runoff may occur. Dispose of empty containers and unused product according to local regulations.

Conclusion

Fencro 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 diafenthiuron and bifenthrin provides rapid knockdown, long-lasting residual control, and broad-spectrum effectiveness, making it a valuable tool for integrated pest management (IPM) programs. When used responsibly and with proper safety precautions, Fencro can effectively protect crops from damage and ensure yield protection.

Additional Guidelines for Applying Fencro

  • Foliar Spraying: Apply Fencro as a foliar spray when pests are first seen or when damage is observed. Repeat applications as needed, but allow at least 10 days between applications.

  • Soil Drenching: Apply Fencro as a soil drench around the base of the plant and allow it to soak into the root zone. This method is particularly effective against pests that attack the roots or lower stems.

  • Integration with IPM Programs: Fencro 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 Fencro may be required to maintain effective pest control.

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