Abstract The fruit of the strawberry (Fragaria ananassa Duch.) contains an important amount of antioxidants and micronutrients, being a source rich in vitamin C and folic acid. Compared to other fruits also it has a high water content, less low molecular weight carbohydrates and a higher glucose / fructose ratio. The growth, production and quality of the strawberry fruit depends on the different agricultural treatments that are carried out during its development season. At present, efforts are being made worldwide to minimize the amounts of chemical fertilizers and pesticides applied to vegetables and edible plants to reduce the cost of its production and the pollution of the environment, without a reduction on the performance. In this sense, there is necessary to search alternatives to integrated pest management in strawberry crop. One of the strategies which has been the most studied in recent years is the use of chitosan to regulate the phytopathogen populations, increase the fruits yields and to improve the quality and commercial life of the fruit. Among the oligosaccharines, chitosan is the most studied and applied in the field of pre and postharvest agriculture. For these reasons, the aim of this review is to highlight the main results found in different studies where the action of this biostimulant on strawberry cultivation has been tested
