Incredible dogs trained to protect vineyards with new method of pest control: 'It's a game to them'

Want a suitable replacement for pesticides? Apparently, dogs just might be it.
Dr. Stephanie Bolton, a sustainable winegrowing director for the Lodi Winegrape Commission, wanted to find eco-friendly ways to combat pests (mainly the vine mealybug) in wine vineyards.
After receiving a $428,000 grant from the California Department of Pesticide Regulation, she went to work, successfully training four dogs known for their above-average sense of smell to find mealybugs and infected vines.
Should the government be allowed to restrict how much water we use?
Definitely
Only during major droughts
No way
I'm not sure

The results were astonishing. According to Wine Spectator, the dogs found mealybugs on average over 97% of the time during three sets of trials. They also detected leafroll viruses around 93% of the time. Once they locate the problem, the dogs sit to alert their handlers to a compromised vine.
If you're worried about the dogs working overtime, don't be. "The canines are rewarded by play; it's a game to them," Bolton added, noting that "the dogs will even improve with time."
Pesticides have been continuously proven to have adverse effects on the environment. According to the British Columbia Ministry of Agriculture, pesticides can pollute the air and soil when improperly applied or disposed of.
There are also restrictions in place for their usage. For example, the U.S. Environmental Protection Agency currently has restrictions on specific toxic pesticides, though some argue that even those aren't enough, citing their harm to humans and bee populations.
Using dogs completely eliminates that problem — and ups the cuteness factor on vineyards by 1000%.
At this point in time, canines aren't used for pest detection on a large scale, but given Dr. Bolton's successful study, they could be. Wine Spectator shared that dogs are being taught to sniff out other pesky bugs in vineyards, suggesting that the future is bright for this one-of-a-kind project.

Cal Poly Humboldt students study how barn owls are used in Lodi vineyards

LODI – In a tiny wooden box perched high off the ground at the Lodi Wine and Visitor Center is a family of six barn owls. For owl parents Poppy and Yarrow, that's a lot of mouths to feed. In an effort to study their daily life, professors and students at Cal Poly Humboldt started a new project. "It's part of this broader research project we got going on with Cal State Humboldt to study barn owls and how they're used in our Lodi vineyards," Winemaker and Lodi Winegrape Commission Executive Director Stuart Spencer said. Over the past 35 years, wine growers across Lodi have used barn owls to control rodents. So much so, many farms have installed these owl boxes within the vines. "A family like this can eat up to 3,500 gophers in one season," Spencer explained. "They're an incredible tool for dealing with rodent pests in your vineyards, and they hunt all night long. It's a great, sustainable way to manage rodents in the vineyard." Using these boxes, researchers had an idea to put GPS tracking devices on the owls to study their behavior. "This owl is going probably half a mile away from us here and feeding in some open fields to the west of us, and then circling back around, and you can see this incredible pattern of where they're hunting," Spencer shared. There are over 170 owl boxes throughout Lodi. On top of studying the owls' patterns, this research is key to understanding how the relationship between farming and wildlife is essential. "We live in our vineyards, you know, they're going to be the healthiest when they're in balance with the overall ecosystem," Spencer said. "The more we can use natural predators like ours to control things in the vineyard, the better off the whole ecosystem would be, the better the quality of the grapes will be, the better the wine will be, and the better off we all are as a community." You can watch the four baby owls in Lodi grow on a YouTube livestream provided by these researchers at Cal Poly Humboldt. CBS Sacramento plans on speaking with these researchers and their process of tracking the owls in the coming weeks.

Dogs could be the saviour of global wine production threatened by disease

For more than a century, English Springer Spaniels have proven invaluable to huntsmen as loyal gun dogs that sniffed and flushed out their quarry. But, now the animal's acute sense of smell is to be harnessed to thwart the threat posed to the world's vineyards by viruses and bugs. A study has found the English Springer is adept at detecting mealybugs and leafroll that can decimate grape harvests producing some of the finest wines. The pilot research project in California, which involved two English Springer Spaniels named Sauvi B and Zinny, discovered that using these working dogs was the cheapest way to efficiently scour acres of vineyards for potential infestations and contamination. Sauvi B, along with a German Shorthaired Pointer named Cab, was able to detect the presence of vine mealybugs 97.3 per cent of the time, as well as rule out such an infection 100 per cent of the time. Zinny worked with a black Labrador named Malbec and was successfully able to detect the Leafroll 3 virus 93.4 per cent of the time. Stephanie Bolton, the grower research and education director at Lodi Winegrape Commission, who conducted the tests, told a recent winemakers' summit in San Luis Obispo that the use of so-called 'winery dogs' could help protect vineyards from common forms of blight. The vine mealybug, or planococcus ficus, is a pest that carries the Leafroll 3 virus which adversely affects a vine's health and reduces crop size. This mealybug spreads quickly because it regularly reproduces during a single season. It can be transported by birds, pruning shears and mechanical harvesting equipment, prompting intensive cleaning routines to help prevent its spread. As reported by Wine Business, an online industry magazine, Ms Bolton told the winemakers' summit: 'The robust olfactory senses of canines can detect vine mealybugs and Leafroll 3 virus in nursery mother blocks and commercial vineyards at a level, which contributes to integrated pest management and is both economically feasible and scalable. This holds great potential for the sustainability of our industry.' Referring to the problem caused by leafroll and mealybugs, she added: 'We are not going to get ahead of this challenge if we keep planting infested and infected vines'. As an incentive, the dogs would receive a reward after spotting infestations, leading to them viewing their work as a game. The animals' detection rate is expected to improve over time as they become more efficient through practice. The magazine said that Ms Bolton and her colleagues are now presenting their findings to leading members of the industry to try to establish how a 'canine detector programme' could be rolled out. The trial was funded with a $428,000 (£350,000) grant from the California Department of Pesticide Regulation. The dogs, who came from Hungary and Canada, were trained at Lisa Finke's Canine Detection Services in Fresno. Ms Bolton has been experimenting with dogs working in vineyards since 2020 after learning that canines were used to detect infections in the citrus growing industry. Mealybugs are often first noticed as a fluffy white wax on leaves, but closer inspection typically reveals the presence of eggs underneath. Large populations of mealybugs can stunt growth and cause premature leaf drop. The Royal Horticultural Society website says several species of mealybug, including Pseudococcus calceolariae (Glasshouse mealybug), Pseudococcus longispinus (Longtailed mealybug), Planococcus citri (citrus mealybug) and Rhizoecus species (root mealybugs), occur in greenhouses or on houseplants within the UK. Other research has established that dogs can also be used to sniff out other invasive species that can destroy vines, with dogs able to recognise the scent given off by powdery mildew. The use of dogs to detect such outbreaks can also help reduce the industry's reliance on pesticides. English Springer Spaniels have long been used as sniffer dogs by police and the military to detect explosives, drugs, and weapons. These gun dogs, traditionally used to flush out and retrieve game, are descended from the Norfolk and Shropshire spaniels of the mid-19th century, although the breed has since split into separate working and show lines. English Springers are also closely related to the Welsh Springer Spaniel and the English Cocker Spaniel. Broaden your horizons with award-winning British journalism.
