Nanocarriers: An Emerging Tool for Micronutrient Delivery in Plants

Presently, the requirements of food have increased with increasing population, hence the necessity for effective agricultural technologies that enhance the productivity of crops and reduce environmental risks. Nanotechnology in medicine enhances therapeutic accuracy by the targeted delivery system to the diseased cells and also disabling biological barriers. The application of nanomaterials or nanocarriers as nano-pesticides, nano-fertilizers, and sensors might enhance the productivity of crops, thereby making these emerging areas of research nowadays. The nanocarriers effectively enhance the micronutrient, fertilizer, and agrochemical delivery within the plants. Also, nanocarriers have the potential ability to protect plants against pathogens through numerous mechanisms mainly reactive oxygen species (ROS). The nanocarriers have the ability to replace conventional pesticides and fertilizers, and also reduce environmental impacts. This book chapter focuses on the various nanocarriers such as carbon and polymer-based nanocarriers and its application in micronutrients, and pesticide delivery system. We also focus on the toxicological aspects of nanocarriers and its environmental impacts.
