WSU Faculty, Dr. Lav Khot, Presents at 2017 APS Annual Meeting in San Antonio

Dr. Lav R. Khot
State-of-the-art on Sensing Technologies for Plant Disease Detection

Lav Khot, Assistant Professor,
Department of Biological Systems Engineering
IAREC, Washington State University

APS Annual Meeting 2017 website headerBrief description: Site-specific disease detection is one of the key aspects of effective crop (loss) management. Recent advances in detectors (optical, chemical) have improved feasibility of development and use of rapid non-contact/nondestructive sensing techniques in plant diseases detection. Advances in versatile ground-, aerial-platforms, and internet of things (IOT)-enabled data acquisition, in-field onboard processing, and near-real-time delivery techniques have also helped in easing logical concerns, about time and labor, of field level crop scouting. This talk will thus focus on state-of-the art in the field of chemical and optical sensors, platforms (e.g. small and mid-sized unmanned aerial systems), and IOT based technologies that could be an aid in rapid disease detection. Through case studies in specialty crops, the talk will discuss the feasibility of the technology in field level disease detection as well as challenges that need further research before its commercial use.

Washington State Professor Finds Sky-high Opportunities for Drones in Agriculture

February 27, 2017  |  Washington Farm Bureau

Many farmers and ranchers are already benefitting from drone technology, but the work of researchers like Dr. Lav Khot is showing that we’ve only scratched the surface of what this relatively new technology can do for agriculture. Khot works for Washington State University’s Center for Precision and Automated Agricultural Systems and in the agricultural automation engineering research emphasis area of the Department of Biological Systems Engineering.

Plant biologists welcome their robot overlords

Old-school areas of plant biology are getting tech upgrades that herald more detailed, faster data collection.

January 25, 2017 |by Heidi Ledford, Nature – International Weekly Journal of Science

drone flying over cropAt Washington State University in Pullman, biological engineer Sindhuja Sankaran’s lab is preparing to deploy drones carrying lidar, the laser equivalent of radar. The system will scan agricultural fields to gather data on plant height and the density of leaves and branches. Sankaran also uses sensors to measure the volatile chemicals that plants give off, particularly when they are under attack from insects or disease. She hopes eventually to mount the sensors on robots.

Agtech: Higher yields, lower costs, better environmental protection

Dr. Lav Khot operating a drone in flight

Fall 2016 | Washington Business Magazine, by Richard S. Davis

Advanced technology has contributed to tremendous growth in production since the middle of the 20th century, while farmers have been able to reduce inputs, including labor, chemicals, and energy.  The agricultural and food industry accounts for 13 percent of Washington State’s economy. Biotech, “flying tractors”, designer orchards, and robots have changed everything on the farm, from planting to harvest to packing house.

Drone captures vineyard irrigation data

NBC Right Now logo Growing wine grapes with less water: The study Khot is involved in is an effort to reduce the amount of irrigation water used to grow wine grapes by applying water directly to the roots of a vine in the ground, instead of dripping water on the ground near the trunk. The project is led by WSU professors Pete Jacoby and Sindhuja Sankaran, both affiliate faculty members of CPAAS. » More ...

DJI, WSU to partner on ag drone research, education

DJI, the world’s leading commercial drone manufacturer, and Washington State University Tuesday announced their intention to partner on research and use of unmanned aerial systems in precision agriculture. WSU’s Center for Precision & Automated Agricultural Systems (CPAAS), based in Prosser, Wash., will lead the effort. CPAAS provides the vast agricultural community in the Pacific Northwest with the latest technology for increased farming efficiency and environmentally friendly production. » More ...

Phenotyping in the field goes high-tech

Good Fruit Grower | Nov 25, 2015

WSU researcher is using thermal infrared cameras and other sensor technologies to study fruit traits.

Researchers have made strides in the study of fruit genomics in recent years, but less ground has been gained in the field of phenomics, the measurement of plant and fruit traits.

Genotyping and phenotyping go hand in hand; one must know if a specific fruit trait is present, and in what form, in order to tie the trait to a specific gene.
