Agricultural Colorants are used to enhance the appearance and quality of crops. They can be either natural or synthetic in nature.
Agricultural Colorants are a group of dyes and pigments that are added in fertilizers and seed treatment products to differentiate them. These colorants help in separating pesticides from insecticides and help to improve the quality of agricultural products. Seed treatments are used to enhance seed germination, stand establishment, and crop yields under changing climatic conditions. Seed coating technologies are being investigated for adapting crops to abiotic stresses such as drought stress or saline soil conditions. These abiotic stresses can negatively impact seed growth, crop productivity and food quality. Biological seed treatments, such as microbial inoculants and biofertlizers, can be applied by seed coating to promote crop growth, yield, and nutrient use efficiency. However, the success of these applications will depend on the development of bio-inoculants that can be adapted for large-scale application. The use of fertilizers to support healthy crop production is a common practice among farmers. However, these products are expensive and can harm the environment if they are not used properly. Besides, the use of these products can also lead to runoff that pollutes surface and groundwater systems. Fertilizers are designed to supply nutrients to plants in a controlled manner, so they need to be applied at the right time and in the proper amounts. Natural fertilizers, such as composted sewage sludge or cow manure, provide nitrogen and other essential nutrients to plants slowly over time. They can also help improve soil structure and contain minor nutrients that are not found in synthetic fertilizers. Synthetic fertilizers produce harmful pollutants such as nitrous oxide, an ozone-depleting and climate-warming gas. They are a significant source of emissions to the atmosphere, especially when combined with other pollution sources like livestock manure. Agricultural Colorants can be used as a turf treatment for overseeding or to improve the appearance of turf during dormancy. They may also be used as a substitute to overseeding under severe water restrictions or in situations where seed prices are volatile. The use of Agricultural Colorants can reduce the cost of overseeding and may be a more efficient alternative. They require minimal turfgrass preparation and can enhance green color and appearance. Turf colorants can also be used to increase surface temperature during drought conditions and to help reduce mottled grassy appearances due to winter or summer stress. Some colorants have been shown to reflect potentially harmful near infrared (NIR) light, which can improve turf quality and vigor. Some of the newer pigments have been found to reflect NIR light, which is beneficial for turfgrass. However, this effect can vary depending on the type of product used and the amount of time that a colorant remains applied to the turf. Variegations in the foliage and flowers of ornamental plants are often sought after by horticulturists and garden enthusiasts. These phenotypes can be de- sired in many plants and include green leaves with other colors, such as red or yellow, alone or combined. Some species of plants are cultivated for their flowers which display aesthetically pleasing traits, such as flower breaking, which involves petals that exhibit irregular distributions of pigments. Although these phenotypes can be desirable, viruses that cause these foliar or floral characteristics should not be applied to ornamental plants unless they are not likely to transmit to agronomic crops through whiteflies and thrips.
