When life throws you grapes, make wine
With increased pressure to feed a growing global population, farming families have embraced modern science and technology to maximise output at whatever cost. So when John and Wilma Huisman took over the family farm in Balkbrug, in the eastern province of Overjissel, Netherlands in 1993, they chose a different approach. The couple embraced organic farming methods, valuing quality over quantity. ...

First raisin grape that dries naturally on vine developed
Agricultural Research Service (ARS) scientists in California have developed a new raisin grape that dries naturally on the vine, making it unnecessary for growers to cut into the woody “canes” connecting the grapes to the mother vine weeks before harvest. For mechanically harvested raisin grapes like Thompson Seedless, growers have to cut the canes each summer, usually about 2 weeks ...

An autonomous robot that eliminates downy and powdery mildew overnight
Robot Thorvald has passed its final tests on Chardonnay with flying colours. This spring, it went through the rows of vines and projected its ultraviolet rays on the leaves to eliminate powdery and downy mildew completely autonomously. To successfully suppress the fungal diseases, it had to work by night. “What makes it possible for us to use UV to control these plant pathogens is we ...

More California winemakers using less water to grow grapes
The grape vines that grower Frank Leeds tends in Napa Valley stand among the unheralded heroes of California's drought, producing decade after decade of respected Cabernets and other wines without a drop of added water. In a state where farms and dairies take the biggest gulp of the water supply, Leeds and the owners of his Frog's Leap Winery are among a minority - but a growing minority - of ...

How policies could help winegrowers adapt to climate change
Grapes are sensitive to small changes in temperature, rain and sunlight, meaning climate change will have implications for wine producers worldwide. This study assessed local vulnerabilities and adaptation strategies in two wineproducing areas in France. The findings may help growers to develop suitable methods of adapting to long-term climate change. Changes to climate are already having ...

Florendovirus: new genus of virus in plant genomes
While the extent and importance of endogenous viral elements have been thoroughly researched in animals, there is a dearth of knowledge when it comes to plants. Within the framework of a broader international effort, researchers at INRA Versailles-Grignon and Cirad have described a new genus of the Caulimoviridae family of viruses, called Florendovirus, whose members have colonised the genomes of ...

Joining consortium to develop `Biochar`: Biological Charcoal Compost
Black to the future (BTF) is a research project to develop an advanced mix of biological charcoal (biochar) and compost with the goal to reduce soil depletion, increase carbon capture, and improve yield quality. The biochar and compost are obtained from agricultural residues in a circular network where farmers are both feedstock producers and product end users. The co-maturation of this compost ...

Purfresh Ozone Container Trials Show Promise for Smoke-Affected Winegrapes
Trials conducted during the 2020 harvest with smoke-exposed winegrapes using controlled ozone (O3) treatments in shipping containers indicate such pre-crush treatments can mitigate and reduce levels of smoke-related volatile phenol (VP) compounds from grapes and produce resulting wines with more favorable sensory and quality characteristics. Purfresh Wine of Hayward, California (formerly branded ...

Simulating Agricultural Climate Change Scenarios using Controlled Growth Chambers
Extreme weather, believed to result from climate change and increased atmospheric CO2 levels, is a concern for many. And beyond extreme events, global warming is also expected to impact agriculture.1,2 Although it is expected that climate change will significantly affect agriculture and cause decreases in crop yields, the full effects of climate change on agriculture and human food supplies ...

Simulating the effect of climate change on agriculture
Increased atmospheric CO2 levels and climate change are believed to contribute to extreme weather conditions, which is a major concern for many. And beyond extreme events, global warming is also predicted to affect agriculture.1,2 While climate change is expected to affect agriculture and reduce crop yields, the complete effects of climate change on agriculture and the resultant human food ...
