**7. Conclusion**

Microemulsion formulation is the most suitable thermodynamically stable formulation for essential oils. Essential oils give maximum stability in microemulsions with optimized surfactants and co-surfactants. Various essential oil microemulsions have been formulated and found very useful for controlling multiple agricultural pests. Many studies revealed that essential oil stability and bio-efficacy could be further improved by using eco-friendly stabilizers and botanical synergists. Essential oil microemulsion could be a better alternative to synthetic pesticides and opens a new corridor for the promotion of the greener way of plant protection in India and across the globe.
