The application of chitosan in the measurement of pesticides

Today, nanotechnology has been entered as a revolution in all branches of science. Including the sciences, agriculture and environment. Chitin chitosan as a matter of) the second most abundant biological polymer after cellulose in nature (This natural polymer skin from various sources, such as crab, shrimp, cuticle achieved [1]. To control pests, fungi and maintenance products and the rise of new diseases, priority ways that Without the use of chemicals to increase the quality and quantity of the product [2]. Chitosan as an amino poly Natural polysaccharide which has a unique structure and properties of multifunctional, including the specification Biocompatibility, biodegradability, oral agents, anti-fungal and anti-bacterial properties it. With Due to its importance to deal with a wide variety of applications tensions in the planting, harvesting and post for crops has found, and also because of its use in the protection of the environment [3].
