The growing global population is driving the stipulation for food and agronomical resources. The application of traditional agrochemicals in the agriculture sector has wide-ranging consequences on both organisms and the environment. Prospects in formulating nanoemulsions used as nano delivery systems for agrochemicals in fields, crop protection, and farm animal management by improving animal and plant efficiency in agriculture. This review places emphasis on bio nanoemulsion formulation for different agricultural applications such as pesticides, fungicides, acaricides, insect and tick repellents, herbicides, and nematicides, which reduce toxicity and, in turn, improve environmental sustainability. Overall, nanoemulsion paves the way to more efficient, eco-friendly and reliable implementation in agronomics. The targeted active substance is advantageous using a method of nanoemulsion due to their unique size to surface area ratio. This allows better penetration through plant cuticles and insect agrochemicals. The controlled release mechanisms inherent in nanoemulsion systems can minimize the environmental impact of agrochemicals. By allowing for targeted application at lower dosages, nanoemulsions protect active ingredients from disintegration due to factors such as light and heat fluctuations. This stability ensures that the agrochemicals remain effective over longer periods, enhancing their usability in various agricultural settings.
