1. What is Spirotetramat 22.4%?

• Chemical group: Tetramic acid derivatives
• Mode of action: Two-way systemic (moves both upward via xylem and downward via phloem), blocks lipid synthesis in insects – halting development and leading to death
• Formulation: OD (oil dispersion) – oil-based suspension in water
• Characteristics: Effectively targets both larvae and adults, safe for beneficial insects

👉 Spirotetramat is highly favored in clean and sustainable agriculture due to its strong mobility, long-lasting efficacy, and compatibility with IPM programs.

2. Mode of Action of Spirotetramat

Spirotetramat inhibits lipid synthesis enzymes in insects, resulting in:

• Immediate developmental arrest after feeding or sap-sucking
• Insects cannot molt or reproduce
• Gradual but complete mortality

Notably, once absorbed through leaves, it moves to both new shoots and roots, offering full-plant protection – a rare feature in insecticides.

3. Key Features Compared to Other Actives

✅ Two-way systemic action – reaches the entire plant, including emerging leaves
✅ Kills eggs, larvae, and juveniles – breaks the insect life cycle
✅ Safe for beneficials – bees, ants, spiders, and predators are unaffected
✅ Long residual effect – lasts 10–21 days
✅ Ideal for IPM, GlobalGAP, and VietGAP certified production

4. Target Insects Effectively Controlled

Pest Type	Typical Host Crops
🐛 Mealybugs	Mango, longan, durian, coffee
🐜 Soft-bodied aphids	Citrus, pomegranate, soursop
🐞 Thrips	Cucumber, tomato, melon, chili
🕷 Red spider mites	Tomato, cotton, watermelon
🐛 Piercing-sucking larvae	Leafy greens, chrysanthemum, orchids

5. Usage Guidelines and Dosage

• Recommended rate: 10–25 ml per 16–25 liters of water depending on pest pressure
• Application timing: Early infestation or at juvenile stage
• Spray method: Evenly cover both leaf surfaces; focus on high egg-laying areas
• Reapplication interval: Every 10–14 days in high pressure conditions
  📌 Can be mixed with biological spreader/sticker agents for better uptake

6. Precautions When Using

• Avoid spraying during intense sunlight or before rain
• Do not mix with alkaline products (e.g., lime, sulfur)
• Avoid overuse: no more than 2 consecutive applications per crop
• Observe proper pre-harvest intervals (PHI): 7–14 days depending on crop
• Store in a cool, dry place away from direct sunlight

7. Conclusion

Spirotetramat 22.4% is a next-generation two-way systemic insecticide, offering long-lasting, safe, and highly effective control of aphids, mealybugs, thrips, mites, and other sap-sucking pests. It's especially suitable for high-value vegetables, fruit orchards, and organic production systems.

👉 Choosing the right deep-acting, wide-reaching insecticide helps farmers reduce pest risk, save costs, and protect long-term yields.
