Why Buprofezin Remains a Cornerstone Insecticide in 2025

1. Unique Value Proposition

Buprofezin (a thiadiazine-class insect growth regulator) has maintained global relevance due to its:

• Unmatched efficiency against nymphal stages of hoppers/whiteflies

• Minimal ecological disruption (LD50 >5,000 mg/kg for mammals)

• Cost-effectiveness at $12–18/ha versus alternatives like flonicamid

2. 2025 Application Hotspots

3. Resistance Management Protocol

The 3-System Rotation™ adopted by IRAC in 2024:

1. Buprofezin (Group 16) → 2. Spirotetramat (Group 23) → 3. Afidopyropen (Group 9D)
   Field trials show 82% efficacy retention vs. mono-use systems

4. Regulatory Crossroads

• Banned in EU since 2023 (persistent metabolite TP-303)

• US EPA 2025 Special Local Need labels for California citrus

• China's new 14-day PHI for tea plantations

Operational FAQ

Q: How does 2025's El Niño affect application?

Delay sprays if >35°C – volatilization losses exceed 30%.

Q: Best tank-mix partners for orchards?

Hexythiazox (miticide) + potassium silicate (anti-feeding adjuvant)

Q: Organic alternative with similar action?

Azadirachtin (neem) + diatomaceous earth (physical barrier)
