Bromopropylate is a contact acaricide widely used in agriculture to control mites on crops. It belongs to the organochlorine group and is effective against a variety of mite species, including spider mites and rust mites. Known for its long-lasting residual activity, Bromopropylate is applied to protect fruits, vegetables, and ornamental plants from mite infestations.

Key Features

1. Contact Action: Kills mites upon direct exposure.

2. Long Residual Activity: Provides extended protection against mites.

3. Broad Applicability: Effective on fruits, vegetables, and ornamentals.

4. Specific to Mites: Focused action with minimal effects on other pests.

Applications

Target Pests

• Spider mites (Tetranychus spp.)

• Rust mites

• Red mites

Usage Areas

• Fruits: Apples, pears, citrus, and stone fruits.

• Vegetables: Tomatoes, cucumbers, and peppers.

• Ornamental Plants: Roses and other flowering plants.

Application Methods

• Foliar Spray: Applied directly to infested areas for optimal results.

Mode of Action

Bromopropylate disrupts the normal metabolic processes of mites by interfering with their respiration. It is highly effective against adult mites and helps prevent population buildup.

Advantages

1. Effective Mite Control: Targets a wide range of mite species.

2. Residual Efficacy: Reduces the need for frequent applications.

3. Crop Compatibility: Suitable for use on a variety of crops.

4. Resistance Management: Can be rotated with other acaricides to manage resistance.

Safety and Environmental Considerations

Handling and Storage

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

• Store in a dry, cool place, away from food, water, and incompatible substances.

Environmental Impact

• Aquatic Toxicity: Harmful to fish and aquatic organisms; avoid runoff into water bodies.

• Pollinator Safety: Use with caution during pollination periods to protect bees.

Human Health Risks

• Low acute toxicity to humans, but prolonged exposure may cause irritation.

• Follow safety guidelines and label instructions to minimize risks.

Limitations

1. Narrow Spectrum: Effective primarily against mites, limiting its use for other pests.

2. Environmental Concerns: Potential risks to aquatic organisms require careful application.

3. Resistance Potential: Overuse can lead to resistance in mite populations.

Conclusion

Bromopropylate is a reliable acaricide for controlling mites in various agricultural settings. Its long-lasting residual effect and broad crop compatibility make it an essential tool for farmers. Proper application and adherence to safety guidelines ensure effective mite control while minimizing environmental and health risks.
