NASA Scientists Develop Advanced Imaging Instrument to Combat Grapevine Disease
Scientists at NASA have made a significant breakthrough in helping grape growers combat a devastating disease known as grapevine leafroll-associated virus complex 3 (GLRaV-3). This disease poses a major threat to the grape industry, causing billions of dollars in damage and losses every year.
GLRaV-3 is primarily transmitted by insects and can result in reduced crop yields and spoiled fruits. Early detection and treatment of the disease are crucial, but current methods are expensive and require molecular testing and meticulous inspections.
However, researchers at NASA’s Jet Propulsion Laboratory have developed an advanced imaging spectrometer called AVIRIS-NG, which has the potential to revolutionize the detection and treatment of GLRaV-3. This next-generation instrument records the interaction of sunlight with chemical bonds and has previously been utilized to monitor wildfires, oil spills, and air pollution.
In a recent study, the research team used AVIRIS-NG to examine grape crops in California. The imaging spectrometer was able to identify the early stages of GLRaV-3 before visible symptoms appeared, thanks to its ability to detect cellular stress in plants. By combining the imaging system with machine learning and computer models, the researchers achieved an impressive 87% accuracy in differentiating between infected and non-infected vines.
To confirm the system’s findings, ground crews evaluated 300 acres of crops during a heatwave, further confirming the accuracy of the imaging system. This early detection can provide farmers with up to a year to prepare and combat an outbreak, giving them a crucial advantage.
The study results indicate a potential breakthrough in early treatment and prevention of crop diseases worldwide. Researchers now hope to expand the use of this technology to monitor and combat other crop diseases on a global scale.
This groundbreaking research by NASA scientists not only promises to save grape growers billions of dollars but also has the potential to protect other crops from devastating diseases. With the ability to detect and treat diseases at an early stage, farmers can take proactive measures to prevent crop damage and ensure the health and productivity of their farms.
