Name of technology: A method for preparation of plant based Nano-emulsion for agricultural use thereof
Patent No./Patent application No.: 201711023901 A
Date of filing/granting: 07/07/2017
Technology related to: Crop production, crop protection

Brief Description of Technology including Salient Features:
Thymol is water insoluble and problem of insolubility ameliorate through its nano-emulsion. Thymol nano-emulsion has been prepared by synthetic surfactant and which is not safe for use in agriculture and food. In present invention, biosurfactant, saponin (a plant extract) has been used for synthesis of plant based nano-emulsion which is safe for said purpose. In agriculture 40-50% of agrichemicals are not reaching to targets. Nano sized droplets of nanoemulsion effortlessly absorbed by plant cell and microbes and act as sustainable plant growth and protection agent which solve the problem of runoff/drift off agrochemicals. Prepared plant based nanoemulsion in which thymol is encapsulated in saponin and further coated with Zinc molecules, prevent the sudden expose of thymol to cellular system which prevent the toxicity of thymol and Zinc serves as micronutrient for sustainable plant growth and provides nutrition to growing plant. Thymol nanoemulsion is very effective at very low dose, therefore, economical for users.

Utility:  Plant growth promoter, plant nutrient, crop protection against pathogens
Impact, if Adopted: NA
Social Impact: Reduces the environment hazards and/human health. Eg. thymol nanoemulsion is biodegradable and synthesized by non-synthetic material and can be very safe for agricultural application.
Technology Spread: NA
Target users/stakeholders: Farmers
Business and Commercial Potential, if any: Yes
Target Market/Users: Agrochemicals
Status of Existing Comparable Process/Product: NA
Advantage over Existing Process/Product: Better availability, less toxicity & reduce application losses
