Frost protection: nutrition, phenology and biostimulation. Late frost at the end of winter or early spring cause every year severe damage to different crops, including vineyards and fruit trees. This phenomenon is predicted to increase in certain regions with increased climate change. Plants have developed different mechanisms to prevent the formation of ice crystal in the cell or increase the tolerance to freezing. Many strategies and products against freezing have been created and developed from the study of these mechanisms. When trying to protect orchards from frost damage, growers should thing interms of frost management. Frost management includes both active (wind machines, over-tree sprinkling, heaters) and passive (selecting of variety and site, management of soil, fertilization and products against frost, among them) methods of minimizing frost, among them) methods of minimizing frost risk and damages. In this article, we focus on the different kind of products to protect fruit crops against frost.
