Pollination by drones: an alternative for cherry production

The initiative aims to optimise fruit production and alleviate bee pollination difficulties at certain times of the year.
The bacterial canker of sweet cherries is caused by the bacterium Pseudomonas syringae pv. syringae (PSS) van Hall (Romoli, 1963, Latorre et al., 1980). This pathogen is commonly associated with humid and cold climates (Latorre, 2008). The pathogen P. syringae can colonize any plant tissue without causing infections or symptoms. However, the bacterium requires a wound or natural opening, along with conditions of moisture or standing water, to infect trees. As a result, autumn becomes a critical period for preventive management.

The most evident symptoms of bacterial canker in sweet cherry are a dark canker, often accompanied by gummosis (reddish-brown exudate) (Latorre, 2008, CABI, 2020) (Figure 1). Symptoms commonly develop at the base of trees, particularly in younger trees, which are more susceptible to damage caused by machinery, rodents, frost, and irrigation. These factors provide ample opportunities for PSS infection.

Research has examined the impact of using cherry juice and pomace in beer. The results of chemical analyses show that the addition of these elements increases the concentration of phenolic compounds in beers and consequently also the antioxidant activity.

In frozen fruit B2B, the right balance between sweetness and acidity is essential: it shapes taste, formulations, compliance, and supply stability. A poor choice may lower consumer acceptance, raise costs, and undermine competitiveness in highly demanding international markets.
