Specially trained dogs are proving to be valuable allies for winemakers in the fight against damaging pests and vine diseases. Recent trials conducted by researchers at Cornell University revealed that these canine detectives can effectively sniff out invasive species, such as the spotted lanternfly.
In a study highlighting the capabilities of two dogs, Dia, a Labrador retriever, and Fagan, a Belgian Malinois, it was found that they were able to detect 3.4 times more egg masses of the spotted lanternfly than human participants in nearby forested areas. The study emphasized that while humans performed better in the vineyards where a systematic search could be conducted, dogs excelled in wooded settings where their sense of smell is particularly sharp.
The urgency of this research stems from the substantial threat the spotted lanternfly poses to grapevines, with infestations potentially leading to mortality rates in vines as high as 80% to 100% within a single growing season, according to professor Angela Fuller from Cornell University.
Dogs are also trained to detect powdery mildew, a globally prevalent fungus. Research published in the Journal of Veterinary Behavior demonstrated that dogs can recognize the scent associated with this disease, although further investigation is needed to confirm their effectiveness comprehensively.
In California, a pilot project showed that dogs could accurately detect leafroll 3 virus and vine mealybugs, with specific breeds, including Labradors and Spaniels, being trained for this purpose. These findings not only highlight the potential for canines in viticulture but also suggest their capability in addressing various agricultural challenges.
The implications of these studies paint a promising picture for integrated pest management in vineyards, with dogs serving as a proactive tool for early detection and intervention against potential threats.
