Abstract :
Sweet pepper fruit has a remarkable nutritional value and its production and consumption has been increased today in the country. However, this fruit is very susceptible to postharvest diseases and major part of produced pepper is lost during the storage and marketing due to the inability to control of its fungal and bacterial diseases. Today, the use of safe methods to control diseases in agricultural products is of interest to researchers. ZnO nanoparticles are one of the effective treatments in control of agricultural diseases. However, the production of metal nanoparticles is usually done by physical and chemical methods, which is doubtful by the consumer in terms of safety. But in recent years, a safe method of green nanotechnology in the production of metal nanoparticles has been developed. Green nanotechnology is an environmentally friendly method that uses plant compounds and residues to produce nanoparticles. In this experiment, at first ZnO nanoparticles was produced using carrot peel extract and then the effect of these nanoparticles on the control of sweet pepper diseases, including Fusarium and Pectobacterium in in-vitro condation was investigated. The results showed that ZnO nanoparticles at concentrations of 0.1 and 0.2 effectively control the incidence of postharvest diseases in sweet pepper fruit in in-vitro conditions, and it can be used as an effective and safe treatment to increase the postharvest life of sweet pepper fruit.
