Buprofezin is an insect growth regulator (IGR) widely used to control sap-feeding pests such as whiteflies, planthoppers, and scale insects. It disrupts the development of these pests by inhibiting molting and chitin synthesis, making it highly effective for managing immature stages while minimizing impacts on beneficial insects.

Key Features

1. Targeted Action: Specifically effective against nymphal stages of pests.

2. Low Toxicity to Beneficial Insects: Ideal for integrated pest management (IPM).

3. Long Residual Effect: Provides extended protection for crops.

4. Environmentally Friendly: Minimal impact on non-target organisms when used as directed.

Applications

Target Pests

• Whiteflies (Bemisia tabaci, Trialeurodes vaporariorum)

• Planthoppers (Nilaparvata lugens, Sogatella furcifera)

• Scale insects (Coccus hesperidum, Aonidiella aurantii)

• Leafhoppers (Amrasca biguttula)

Usage Areas

• Field Crops: Rice, cotton, and maize

• Vegetables: Tomatoes, cucumbers, and peppers

• Fruits: Citrus, apples, and mangoes

• Ornamental Plants: Roses and other decorative species

Application Methods

• Foliar Spray: Directly applied to infested plants for optimal pest control.

Mode of Action

Buprofezin inhibits the synthesis of chitin, an essential component of the exoskeleton in insects. By disrupting molting and development, it effectively controls nymphal stages and prevents population buildup. It also exhibits some ovicidal activity, reducing egg viability.

Advantages

1. Selective Toxicity: Targets pests without harming beneficial predators and pollinators.

2. Resistance Management: An alternative mode of action to conventional insecticides.

3. Extended Residual Activity: Reduces the need for frequent applications.

4. Broad Crop Compatibility: Safe for use on a variety of crops.

Safety and Environmental Considerations

Handling and Storage

• Wear appropriate personal protective equipment (PPE) during handling and application.

• Store in a cool, dry place, away from direct sunlight and incompatible substances.

Environmental Impact

• Aquatic Safety: Avoid runoff into water bodies to protect aquatic life.

• Bee Safety: Minimal impact on bees when applied during non-flowering periods.

Human Health Risks

• Low acute toxicity to humans; avoid direct contact with skin or eyes.

• Follow safety guidelines and label instructions to minimize risks.

Limitations

1. Stage-Specific Action: Ineffective against adult pests, requiring complementary control measures.

2. Resistance Potential: Overuse can lead to resistance; rotate with other insecticides.

3. Environmental Precautions: Requires careful application to avoid contamination.

Conclusion

Buprofezin is a highly effective and environmentally conscious solution for managing sap-feeding pests. Its unique mode of action, selectivity, and compatibility with IPM strategies make it a valuable tool for sustainable pest control in agriculture. Proper application ensures optimal results while safeguarding non-target organisms and the environment.
