With a particular focus on addressing the weather (temperature) concerns of vineyards - viticulturists - Frostdefense Envirotech personnel and their advisoty team provide a range of relevant serices from * assessments of the specific needs of particular vineyards creating a customized frost management intervention; provision of technology to reduce frost damage; enabling customers to maintain profitability; to manage labor and mechanized practices; reduce the costs of frost management and provide predictive analytics to guide application of the technology = assist growers with decision making regarding frost management during the entire frost season. The effort is providing solutions that allow delay of time when new buds break in spring. to minimize damage from early spring frost and improve labor and mechanization management. Solutions are based on a non-toxic / non hormonal, organic, and environmentally friendly spray - a not previously available physiological base method that slowdown endogenous plant physiological development past the riskiest frost window without delaying harvesting.
