Freedom Rootstock*


February, the month of love, romance or, as some may say, chemistry. Mostly, we view the chemical compounds that attract us to potential mates as positive. For the vine mealybug, their sex pheromone may be their undoing.

As explained in the Research Focus article below, two USDA-ARS scientists—Jacob Corcoran and Walt Mahaffee—have definitively located the vine mealybug’s odor receptor in males that enables them to identify the highly specific sex pheromone emitted by females. The discovery could open the door to further R&D to essentially jam the signal received via their antennae to prevent them from mating and therefore spreading. And it could help enable the development of technology to sniff out the wily insects hiding under bark or in soil, based on their unique olfactory signal. Something to consider as you spray on your cologne… And also a beautiful example of the awesome possibilities of science.

Science is a beloved but often overlooked part of our everyday lives. Consider this infographic showing the volume of research represented in a simple pizza. The base of your garden-variety pie is formed from wheat bred specifically for baking. Breakthroughs in tomato processing have improved sorting and reduced repetitive motion injuries for workers. Advances in pest management reduce the cost of inputs for onion growers—savings that are passed along to pizza lovers who like onions on top. It may not look like a miracle of science, but there’s a lot of innovation in every bite.

How might that translate to the grape and wine industry? The tractor you use began as an invention by a farmer named John Froelich in Northeast Iowa, and has been reshaped, resized and alternatively powered in myriad ways ever since. The varieties of grapes you grow may be thousands of years old or they could be newer Cornell varieties, developed by grape breeder Bruce Reisch, that confer cold hardiness, disease resistance, unique flavors or other traits of interest. The cover crop you use is probably not just grass or random weeds but plants specifically selected, based on trials by your local Extension agent, to improve water holding capacity or enrich soil health and vine nutrition. Your trellising system, row spacing and orientation, irrigation system, sprayer, sensors and other tools and techniques for growing grapes and managing vineyards are all innovations based on science.

And they all started with an idea someone had, seeking some way to solve a problem. Just like Jacob and Walt (the ARS researchers) sought to help combat a pest of economic significance by leveraging its biology against it.

As the Month of Amore concludes, let’s show some love for science and for the big thinkers and diligent researchers whose ideas and innovations make the world a lovelier place. The mealybug might not appreciate their advances, but the rest of us can rejoice!

USDA Reports Declining Number of Farms, Farm Revenue

The USDA’s National Agricultural Statistics Service (NASS) this month announced the results of the 2022 Census of Agriculture, showing a continued decline in the total number of US farms. From 2017 to 2022, the census found, US farmland declined by nearly 20 million acres—from 900.1 million acres in 2017 to 880.1 million in 2022. The census also shows there are now 1.9 million farms in the country, down 142,000 from the previous survey, a number equal to all current farms in New England excluding Connecticut, Farm Progress reports. See complete census data.


“A combination of trade wars, the pandemic and policies that furthered a ‘get big or get out’ mentality pushed more people out of farming in the five years since the last census, than in any other census period this century,” said Agriculture Secretary Tom Vilsack in a statement on the results. “America, and especially our rural communities, cannot afford this trajectory toward larger, but fewer, farms.”


In related news, NASS annual Farms and Land in Farms 2023 Summary shows that there were an estimated 1,894,950 farms in the US in 2023, down 5,700 more farms from 2022. Nearly half of them had less than $10,000 in sales. The biggest change for 2023 is that producers in Sales Class $1,000,000 or more operated 14,160,000 more acres than in 2022.

Using Sex Against Them: Vine Mealybug’s Sex Pheromone Receptor Revealed

By Jacob Corcoran and Walt Mahaffee, USDA-ARS

Smell is, by far, the sense that insects rely on the most to navigate their environment. Some insects have evolved to depend heavily on, for example, vision (e.g., dragonflies) or hearing (e.g., crickets), however, these are exceptions and not the rule. For most insects, it’s all about how things smell. Food sources, mates, oviposition sites, caste members and more are recognized and differentiated based on their unique volatile chemical signatures. These olfactory determinations are critical to their survival. How they make these “decisions” is via odorant receptor proteins present in their “nose.” Disrupting the function of these proteins could be a game-changer—particularly for the grape and wine industry, to which the vine mealybug, vector of the economically critical leafroll virus, poses a major threat.

Up till now, though, very little has been known about insect olfactory proteins. The incredible uniqueness of these proteins has only been recognized in the last decade or so due to dramatic advances in genetic and molecular biology technologies, such as next-generation sequencing platforms. Two prerequisites to targeting insect olfactory proteins—having the ability to 1) identify them in an organism of interest and 2) study their function—have only become tangible relatively recently. Thus, we set out to definitively identify the receptor used by the vine mealybug to detect its own sex pheromone.

Why vine mealybug? Because of its role in spreading the devastating leafroll virus, as previously mentioned. But also because the bugs are incredibly cryptic and therefore hard to spot in vineyards, current control methods are inadequate and at risk of strict regulatory control or ban, and the geographic range of the pest is likely to spread with global warming. Plus, the insect’s sex pheromone, lavandulyl senecioate, is biologically unique—it is literally not found anywhere else in nature. A chemical signal this distinct, emitted into the environment, makes a terrific target to potentially exploit.

The vine mealybug uses roughly 50 different receptors to detect odorant molecules in the environment. Given that female mealybugs emit a sex pheromone that is detected by an odor receptor in male mealybugs and that males’ reproductive fitness relies on their ability to detect these cues, we reasoned that the receptor for the sex pheromone would be one of the most highly expressed receptors in male antennae (their “nose”). Indeed, this approach allowed us to identify a receptor that was highly specific and sensitive to the vine mealybug sex pheromone in our cell-based assay system. Eureka! We give you the first report of odorant receptor gene family expression levels, as well as the identification of the first sex pheromone receptor in soft-scale insects.

Why is this breakthrough important? The identification of a receptor for the vine mealybug sex pheromone will allow for the pursuit of two novel pest control tools: synthetic mating disruptants and species-specific biosensors. Work on disruptants has heretofore been hampered by painstaking and expensive field and behavioral assays. The cell-based approach we used in this study will allow for much more efficient and effective evaluation of synthetic molecules against pheromone receptors, which may speed up their development toward commercial application.

A vine mealybug specific biosensor capable of detecting the pest in the field would be a boon to grape growers everywhere. Imagine being able to detect a mealybug infestation early enough to prevent significant losses from infection and transmission of leafroll virus. And not just in your own vineyard. Such sensors could be spread and networked across larger geographies and linked to automated reporting systems that could monitor the spread of the pest throughout a region or across borders, in true areawide programs.

We’re excited about the applications of this work and eager to see the innovations that will undoubtedly emerge. The vine mealybug’s exceptional sense of smell may yet be its undoing!

Combating Climate Chaos with Adaptive Winegrape Varieties

February 15, 2024 | Sustainable Winegrowing with Vineyard Team

Heavier, longer rainfall interspersed with drought can disrupt grapevines’ natural ability to adapt to climatic changes. Cornell AgriTech’s Jason Londo explains how big weather changes can disrupt vines’ natural process of winter acclimation and deacclimation, increasing the chances they’ll wake up earlier and face greater risk of freeze or frost damage. To reduce inputs and increase sustainability, he says, we need to put the right grape in the right climate.

February 12, 2024 | Wine Industry Network

Michael Kaiser, Executive Vice President and Director of Government Affairs for WineAmerica, an NGRA member-organization, was profiled by Wine Industry Advisor as a “wine industry champion, fighting for the future of America’s wineries.” Michael advocates on behalf of the industry with members of Congress, and with federal agencies such as the USDA and Alcohol and Tobacco Tax and Trade Bureau (TTB). He’s quoted: “A lot of people don’t understand how much trade associations such as WineAmerica do for you, even if you’re not a member. Our work benefits the entire industry.”

The Power of Earthworms: Boosting Soil Health & Crop Yields

February 12, 2024 | Lodi Wine Growers Blog

With advances in chemicals to enhance plant growth and crop yield, many farmers have turned away from the most natural way of boosting their plants: earthworms. From the burrows they form to the casings they leave behind, the earthworms in your vineyard can help improve soil health, vine nutrition and even amplify the taste of your terroir.

DIY Vineyard Rootstock Trials

February 7, 2024 | Good Fruit Grower

As Washington State grape growers adapt to using rootstocks, WSU viticulture extension professionals advise them to do their own on-farm trials. They’ve even put together a guide to step growers through the process. “If enough growers do it, the entire Washington wine grape industry will begin to better understand the seemingly infinite combinations of rootstock, scion and growing conditions as the industry shifts from a long history of own-rooted vines to using rootstocks to protect against phylloxera and nematodes,” Good Fruit Grower reports.

Gardeners Can Now Grow a Genetically Modified Purple Tomato Made with Snapdragon DNA

February 6, 2024 | NPR

The new Purple Tomato is the first genetically modified food crop to be directly marketed to home gardeners vs. commercial growers. The transgenic fruit was developed at Norfolk Plant Sciences by inserting the color gene from snapdragon into tomato, providing not only pigment but also high levels of anthocyanin, a superfood compound. In fact, the new tomato has as much anthocyanin by weight as blueberries or eggplants. The company hopes it will help change Americans’ perception of GMO foods.

Tune into this podcast to hear UC Davis’ Akif Eskalen discuss how to prevent harm with pruning wound protectants and promote recovery if your vines become infected, particularly with biologicals.

Wine and the Sweet Smell of Grandma

February 5, 2024 | Wine-Searcher

If you’ve ever had a red wine that smelled unpleasantly like “grandma’s perfume,” you’ve probably experienced “rose taint.” As WSU’s Tom Collins explained at a session at the 2024 Unified Wine & Grape Symposium, when grapevines emerge from dormancy early (e.g., late winter, early spring), as is becoming more common with climate change, they begin producing new leaves. When oncoming frost kills the tiny leaves, they often remain in the canopy till harvest and end up fermenting with the wine. Just two grams of frost-dried leaves in a kilogram of grapes is enough to produce the effect, he said.

The Legacy of Past Droughts Induces Water-Sparing Behavior in Grüner Veltliner Grapevines

February 5, 2024 | Plant Biology

A longer-term study of hardening, led by scientists in Austria, examined gas exchange in well-watered potted vines that had experienced two previous seasons of drought. The findings suggest that grapevines exposed to drought may adopt a more water-conserving strategy in subsequent seasons, regardless of current soil water availability, with the degree of change influenced by the intensity and duration of past drought events.


Spray Shows Promise Against Smoke Taint

January 30, 2024 | Western Farmer-Stockman

A coating that can be sprayed on grapes on the vine, in development by scientists at Oregon State University, shows promise for preventing uptake of wildfire smoke compounds. The team expects to have the coating available for use in the next several years. It “has the potential to transform the wine industry,” said Oregon State’s Elizabeth Tomasino.

The Stomatal Traits That Conserve Water Without Compromising Grapevine Carbon Gain Depend on Climate Change Severity and Wine-Growing Region

January 22, 2024 | Agricultural and Forest Meteorology

As temperatures rise globally, growers and grape breeders dream of heat-tolerant varieties, but the genetic basis for grapevines’ heat response is complex. Research by scientists at UC Davis shows that stomatal traits that regulate vine carbon gain, water stress and evaporative cooling may be easier targets for breeding, and help reduce both irrigation and warming impacts. “Developing varieties with a range of water-saving trait values would provide plant material tailored to different regions and reduce the risk around future climate,” they write.

Rootstock Research Reaches for Drought Resistance

January 1, 2024 | Grape & Wine Magazine

Luis Diaz Garcia, rootstock breeder at UC Davis, is developing novel approaches to screen grapevine germplasm for native adaptive traits to drought more efficiently. Genomics, robotics, proximal sensing and artificial intelligence are some of the tools he’s using to speed up this time-intensive part of the breeding process: finding the traits in existing varieties.

Ozonated Water Spray Does Not Suppress Grapevine Powdery Mildew or Grape Mealybug

January 2024 | American Journal of Enology and Viticulture

Following studies showing that ozonated water spray can suppress powdery mildew growth in a greenhouse setting and kill bugs in vitro, researchers at WSU sought to see if it would work under lab and field conditions to tackle grapevine powdery mildew and grape mealybug. It did not.

Mechanisms of Grapevine Resilience to a Vascular Disease: Investigating Stem Radial Growth, Xylem Development and Physiological Acclimation

December 8, 2023 | Annals of Botany

The trunk disease Esca causes loss of hydraulic conductance due to the occlusion of xylem vessels. Grape research from INRAE indicates that grapevines’ natural resilience to this vascular disease may be enhanced by modified cropping practices, such as avoiding late-season topping, in Esca-symptomatic plants.

This Texas Scientist Trains Dogs to Sniff Out Invasive Species

October 25, 2023 | Texas Monthly

The Texas Tech Canine Olfaction Research and Education Lab recruits shelter dogs to train them on “conservation detection” work, sniffing out invasive species, agricultural pests and hazardous pollutants. Scientists there have trained their charges to find powdery mildew before it’s visible to the naked eye. And more recently, they’ve zeroed in on spotted lanternfly egg masses, which the dogs find 95 to 99% of the time. Center Director Nathaniel Hall believes that “dogs across the country,” including household pets, “could be leveraged for these types of tasks.”

Catching Spores: Linking Epidemiology, Pathogen Biology, and Physics to Ground-Based Airborne Inoculum Monitoring

January 22, 2023 | Plant Disease

This paper was published a year ago, but the findings are still fascinating. They highlight an approach to disease management by conceptualizing airborne inoculum as particles to better understand their dispersal and thereby improve monitoring. The paper includes simulations showing how particles move in complex agricultural environments, illustrating the limited sampling area of common air samplers today.
