Applications of biopolymers in agriculture with special reference to role of plant derived biopolymers in crop protection.
Biopolymers are a diverse and remarkably versatile class of materials that are either produced by biological systems or synthesized from biological source materials. Biopolymer seed coating serves as soil stabilizer, seed protector, yield-enhancer, and plant growth regulator. Biopolymers dry quickly, dissolve rapidly in water, form effective water-soluble film, readily adhere to seeds, minimize the required dose of fungicides, and provide excellent control of plant diseases thereby contributing to enhanced plant productivity. Biopolymer seed coatings with various active ingredients precisely provide early access to each sown seed with nutrients, fertilizers, and pesticides in an accurate and timely manner with long lasting ingredients. New biocompatible and biodegradable biopolymers are produced from plants, microbes, animals, renewable agricultural wastes, and feedstocks. Modern biotechnology and nanotechnology tools are used to create new materials by genetic modification of an organism in order to produce greater quantities of a particular biopolymer. Biopolymer applications in agriculture are increasing, and there is an emphasis on further research for more expertise in biopolymer engineering and genetic modification of biological systems to produce designed biopolymers for agricultural use.
