Buprofezin and its uses

1. Chemical Composition and Properties:

• Active Ingredient:

1.?Buprofezin 25% SC: Contains 25% Buprofezin by weight.

2.?Buprofezin 70% DF: Contains 70% Buprofezin by weight.

• Formulation Type:

1.?Buprofezin 25% SC: Suspension concentrate formulation.

2.?Buprofezin 70% DF: Dry flowable formulation.

• Source:

Buprofezin is a selective insect growth regulator (IGR) that inhibits the synthesis of chitin in insects, thus disrupting their molting process and preventing their development.

• Appearance:

1.?Buprofezin 25% SC: Clear, colorless to slightly amber liquid concentrate.

2.?Buprofezin 70% DF: Fine powder, which forms a suspension when mixed with water.

• Solubility:

Buprofezin is slightly soluble in water but forms a stable suspension in water when mixed for spray applications.

2. Mode of Action:

Mechanism: Buprofezin acts as an insect growth regulator (IGR) by inhibiting the synthesis of chitin, a key component of the insect exoskeleton. This prevents proper molting in insect nymphs and larvae, causing them to die before they can mature.

3. Target Pests:

Buprofezin is effective against a variety of sucking insect pests, including:

• Whiteflies
• Thrips
• Aphids
• Leafhoppers
• Planthoppers
• Other similar pests that affect crops.

4. Application on Crops:

• Crops Treated:

Buprofezin 25% SC and 70% DF are commonly used on crops such as rice, vegetables (e.g., tomato, cucumber, peppers), fruits (e.g., citrus, apples, mango), and ornamentals.

• Dosage:

1. Buprofezin 25% SC: Typically applied at a rate of 200 to 400 ml per hectare, depending on the pest population and crop type.

2. Buprofezin 70% DF: Typically applied at a rate of 50 to 150 g per hectare.

• Spray Timing:

For best results, Buprofezin should be applied during the early stages of pest infestation, particularly when pests are in the nymph or larval stages. It is recommended to spray early morning or late evening to reduce evaporation and heat stress.

5. Features and Benefits:

• Selective Action: Buprofezin specifically targets sucking insect pests without significantly affecting beneficial insects, making it safer for pollinators and other natural predators.
• Long Residual Activity: It provides long-lasting control of pests, reducing the need for frequent applications.
• Low Resistance Risk: Due to its unique mode of action, Buprofezin has a low risk of developing resistance in pest populations compared to conventional insecticides.
• Environmental Compatibility: Buprofezin is less toxic to mammals, birds, and beneficial insects when applied according to the product's instructions. It is environmentally friendly if used as part of an integrated pest management (IPM) strategy.

6. Precautions During Use:

• Toxicity: Buprofezin has relatively low toxicity to humans and mammals when used as directed but can cause mild irritation if ingested or if it comes into contact with skin or eyes. It is toxic to aquatic life and non-target insects.
• Protective Measures: Wear personal protective equipment (PPE), such as gloves, goggles, and masks when handling or applying the product. Avoid inhalation of dust or spray mist, and prevent contact with skin or eyes.
• Environmental Safety: Avoid spraying near water bodies to prevent contamination of aquatic environments. Ensure that baits or spray drift do not reach non-target plants or insects.

7. Waiting Period (Pre-harvest Interval):

• Depends on the crop and regional regulations: For rice and vegetables, the pre-harvest interval is typically between 7 to 14 days. For fruits, it is generally between 10 to 21 days, depending on crop type and regional regulations.

8. Storage and Handling:

• Storage Conditions: Store Buprofezin in a cool, dry place, away from direct sunlight, heat, and moisture. Keep containers tightly sealed to prevent degradation of the active ingredient.
• Handling: Handle the product with care to avoid spills or contamination. In the event of a spill, clean up immediately using soap and water. Follow product-specific instructions for proper dilution and application.

9. Toxicology and First Aid:

• Symptoms of Exposure:

1. Skin Contact: Mild irritation, redness.

2. Eye Contact: Irritation, watering.

3. Inhalation: Headache, dizziness, respiratory irritation.

4. Ingestion: Nausea, vomiting, abdominal discomfort.

• First Aid:

1. Skin Contact: Wash the affected area immediately with soap and water.

2. Eye Contact: Rinse eyes with clean water for at least 15 minutes.

3. Inhalation: Move the affected person to fresh air and provide symptomatic relief.

4. Ingestion: Seek medical attention immediately. Do not induce vomiting unless instructed by a healthcare provider.

• Antidote: There is no specific antidote for Buprofezin. Treatment is symptomatic and supportive.

10. Market Information:

Buprofezin 25% SC and 70% DF are available in various packaging sizes suitable for both small-scale and large-scale agricultural use. These formulations are effective for managing insect pests in a variety of crops, offering long-term pest control solutions.

11. Resistance Management:

• Rotate with Other Insecticides: To reduce the risk of resistance, rotate Buprofezin with other insecticides that have different modes of action.

• Integrated Pest Management (IPM): Incorporate Buprofezin into an IPM strategy that includes cultural practices, biological control, and mechanical methods to manage pest populations.
• Monitor Pest Populations: Regular monitoring of pest activity will help determine the optimal timing for application and reduce the chance of resistance development.
