PHOSALONE

Colorless crystals with a slight garlic odor. Melting point 48 ℃, room temperature vapor pressure is negligible. Solubility in water 10 mg/L at room temperature, slightly soluble in cyclohexane, petroleum ether, soluble in acetone, acetonitrile, benzene, trichloromethane, ethanol, methanol, toluene and xylene. Stable and non-corrosive under general storage conditions.

Organophosphorus insecticides and acaricides, with broad-spectrum, fast-acting, penetrating, low residue, no endosorption and other characteristics. It is mainly used to kill pests by touch and stomach poisoning. Used in cotton, rice, fruit trees, vegetables and other crops. Preventing and controlling the cabbage moth, cabbage greenfly, cabbage aphid.

Phosalone is an organophosphate insecticide and acaricide widely used in agriculture to control a broad spectrum of pests. It is particularly effective against sucking and chewing insects, as well as mites, on various crops, including fruits, vegetables, and ornamental plants. Phosalone is valued for its broad activity range and residual efficacy.

Key Features

1. Broad-Spectrum Activity: Effective against insects and mites, including aphids, caterpillars, and spider mites.

2. Residual Effect: Provides extended pest control after application.

3. Contact and Stomach Action: Kills pests through direct contact and ingestion.

4. Wide Application Range: Suitable for use on fruits, vegetables, and ornamental plants.

Applications

Target Pests

• Aphids

• Caterpillars

• Mites (e.g., spider mites)

• Leafhoppers

• Thrips

Usage Areas

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

• Vegetables: Tomatoes, peppers, and cucumbers.

• Ornamentals: Roses and other flowering plants.

Application Methods

• Foliar Spray: Applied directly to plant surfaces for effective pest control.

• Soil Treatment: Occasionally used to target soil-dwelling pests.

Mode of Action

Phosalone inhibits acetylcholinesterase (AChE), disrupting nerve signal transmission in pests. This leads to paralysis and death, effectively controlling pest populations.

Advantages

1. Broad Activity Spectrum: Controls a wide range of pests in diverse crops.

2. Long-Lasting Protection: Reduces the need for frequent reapplication.

3. Dual Action: Combines contact and stomach poisoning for comprehensive pest control.

4. Compatibility: Can be used in combination with other pest management tools.

Safety and Environmental Considerations

Handling and Storage

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

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

Environmental Impact

• Toxic to Non-Target Organisms: Harmful to bees, fish, and aquatic organisms; avoid application during pollination periods and near water sources.

• Residue Management: Follow recommended pre-harvest intervals to minimize residues.

Human Health Risks

• Exposure may cause symptoms like headaches, nausea, or respiratory irritation.

• Strict adherence to usage guidelines minimizes risks.

Limitations

1. Toxicity Concerns: High toxicity to non-target organisms, requiring careful application.

2. Resistance Development: Overuse may lead to resistance in pest populations.

3. Environmental Persistence: Requires careful management to prevent runoff and contamination.

Conclusion

Phosalone is a powerful tool for managing a wide range of agricultural pests. Its broad-spectrum activity and residual efficacy make it a preferred choice for many growers. However, its use must be carefully managed to minimize risks to human health, beneficial organisms, and the environment. Adhering to best practices ensures sustainable and effective pest control.
