It is important that frost control begins on the day of application of the dormancy breaker (hydrogen cyanamide or budbreak uniformity product), regardless of the frost control system used.
)
Frost damage occurs when nucleation begins, namely the intracellular formation of ice crystals. With the preventive application of products capable of lowering the freezing point of tissues, the aim is to delay intracellular nucleation and reduce its triggering temperature, as well as to improve cell membrane stability and repair before, during and after the event.
These tools make it possible to prevent, mitigate and repair damage caused by low temperatures.

After a frost event, it is necessary to carry out disease control treatments. It should be considered that we are in the stages when the cherry tree is most susceptible to diseases, particularly bacterial canker.
During this period, several risk factors coincide: the increase in the Pseudomonas population, the presence of free water, frost events and the progressive opening of plant tissues, which makes plants even more vulnerable to disease pressure.
Therefore, after these rainfall events, it is necessary to adopt the appropriate management practices to preserve the health status of orchards.

Exports are mainly concentrated from November to March, with a volume for the 2023/24 season estimated at 4,000 tonnes. For the 2024/25 season, exports of fresh cherries are expected to increase to 5,000 tonnes, the second highest ever recorded.

Gli strigolattoni rafforzano le difese post-raccolta delle ciliegie dolci contro Botrytis cinerea. Lo studio sulla cultivar Xianfeng mostra che 0,1 μM riduce muffa grigia, lesioni e biomassa fungina attivando fenilpropanoidi, flavonoidi e proteine di difesa.

Managing frost damage in cherry trees requires action from dormancy breaking through vegetative growth. Preventing ice nucleation, protecting cell membranes, and controlling Pseudomonas and bacterial canker can help preserve orchard health, resilience, and productivity.
