As per our beliefs, agriculture is all about nature and natural colors. It may sound odd that dyes are required to colour the agricultural products. But the truth is that agricultural products are in need of colours as much as the artificial products do. From seed treatment to fertilizer colorants, agricultural dyes have extensive use throughout the world in the agricultural field. Most importantly, unlike in other fields where the dyes are used to increase the visual appeal, agricultural dyes perform vital function of identification and differentiation.
