Development of an Integrated Solution to Prevent Spring Frost Damage Using an Aqueous-based Insulating Foam

In recent years, agricultural crops experience unusually early onset of vegetation due to global warming, which can cause major frost damage with devastating effects on crop yields. To mitigate the risk damage, an integrated solution was developed, consisting aqueous-based biocompatible foam and a portable applicator enabling wine cultivators treat up 1000 m2 vineyards one filling containing 10 L foam. The is biocompatible, stable for several days easily removed by rain. Foam application yielded insulation efficiency 1.5°C during spring nights buds covered when combined electrically heated wire. Moreover, it observed that also created 'mini greenhouse' effect at positive temperatures days, might be side helping plants grow this stage year.
