**6.4 Scope of work in promoting essential oil microemulsion in crop protection**

Essential oil based microemulsion formulation is a promising tool for the biocontrol of the pests of economic importance. However, there are still some areas of improvement that should be focused upon in order to promote oil based microemulsion system in the agriculture sector.

1. **The need for combinatory botanicals or synergists**: Essential oil ME in pure form requires a higher rate of application for controlling pest species, which will increase the cost of formulation and limits its usage. So, there is an urgent need for discovering new combinatory or synergistic constituents, which will be very helpful in promoting essential oil ME.

2. **Extraction and refinement of active components**: There are many active components present in the essential oils, and each gives some specific property. So, many research studies are required to extract, isolate, and identify these constituents. After refinement of most active components, Microemulsion formulation will be straightforward and give much fold of efficacy against various insect pests in an economical way.

All these advanced formulations are only up-to the lab level. So, a proper system of endorsement and awareness is required for the promotion of essential oil ME formulation.
