Best Paper Presented by a Young Researcher – The IEEE MetroAgriFor 2020 announces the Conference Award to the research group, Rakesh Ranjan, Rajeev Sinha, Lav R. Khot, R. Troy Peters, Melba R. Salazar-Gutierrez, all from Washington State University, USA. This was awarded to the group for the paper titled “Internet of Things enabled crop physiology sensing system for abiotic crop stress management in apple and sweet cherry”.
The selection of this paper was based on technical merit, originality, potential impact on the field, clarity of the written paper, and quality of the presentation.
Spray without the sprayer – To get good coverage, researchers modified low-cost irrigation emitters to bounce a cone of spray up into the grapevine canopy as part of a trial to optimize the engineering of a solid-set spray delivery system for vineyards underway at the Washington State University’s Irrigated Agriculture Research and Extension Center in Prosser. Lead researcher Lav Khot says the system aims to provide efficient coverage with minimal drift.
Researchers across the country have been collaborating on the idea, which started in tree fruit, for close to a decade now. Matt Grieshop at Michigan State University leads the project, which is funded by U.S. Department of Agriculture Specialty Crop Research Initiative grants.
“We are as good as airblast in terms of coverage and deposition, but with less drift,” said Rajeev Sinha, who recently finished his doctorate at Washington State University while working on the system. “The best thing is the part that’s lost to drift in airblast hits the canopy, too… continue reading the article…
August 13, 2019 | California Dutch AgFoodTech Collaboration Update #17
The summer vacation period was in between the last newsletter in July and this one. We used this period to prepare important next steps for the project. One of these steps was adding Washington State to the initiative, Peter Frans de Jong of Wageningen University & Research and Marcel van Haren visited Washington State and California to further specify next steps in the so called collective CAWADU project for fruit orchard automation.
The first week of our visit we got to know the Washington State fruit sector very well, thanks to great help of Washington State University (WSU) and the Washington Tree Fruit Research Commission. The picture is taken at the WSU extension in Prosser (WA) where Peter Frans and Marcel had the pleasure to present about Fruit 4.0, FME and AgriFoodTech Platform for a large group of students and other interested people…
Experts from WSU, the Washington State Department of Labor & Industries, Microsoft FarmBeats and ASI Robots will share updates on cutting-edge agricultural advances with growers, agricultural industry professionals, and crop consultants.
This year’s event explores the theme of automation in specialty crop production, and includes field demonstrations and discussions of digital agriculture solutions, automation in farm operations, robotics in specialty crops, intelligent orchard sprayers, a survey of autonomy on the farm, and regulations on the use of autonomous vehicles in Washington farming.
Against the gray, late-autumn sky, it’s hard to miss the green plume spraying into the dormant orchard.
It’s a very colorful solution to a nearly invisible problem.
Underlying every pesticide label regulation lie complex calculations of risk to protect workers, bystanders and the environment from drift. But the methods federal regulators use to determine drift allowances from airblast sprayers date back decades — and likely overestimate the risk in modern orchards.
“All the restrictions and statements on labels are based on a set of assumptions of a worst-case scenario,” said Washington State University extension specialist Gwen Hoheisel. “If we could have a better estimate and the worst-case scenario is not actually as bad as it’s currently estimated, it could lead to less restrictive labels.”
That’s why Hoheisel, WSU agricultural engineer Lav Khot and a team of research associates were eager to watch the path of that fluorescent green cloud from the airblast sprayer. To the naked eye, little drift beyond the orchard block could be seen. However, dozens of drift samplers transecting up to 600 feet across the adjacent field were poised to catch and measure any particles that reached them.
BSE graduate students in the Agricultural Automation Engineering research area Haitham Bahlol and Rajeev Sinha presented their work on “Horticultural oil thermotherapy for pear psyllid management”. During the event, Rajeev Sinha spoke to CAHNRS Dean Wright at the 2019 BioAg Symposium
Their poster was awarded the ‘Best Graduate Poster Award’ with $500 scholarship.

PROSSER – WSU’s Lav Khot will look to reduce reliance on broad spectrum pesticides that result in residues on food with an award from the Foundation for Food and Agriculture Research (FFAR).
Khot and his collaborators received one of FFAR’s New Investigator awards for 2018, which includes a 3-year, $300,000 grant. Part of the grant will be used to study the usefulness of ozonated water, or water that has the O3 molecule, also known as ozone, dissolved into it.

To speed robotic advancements that help farmers grow food with fewer resources, scientists at Washington State University and Australia’s University of Technology Sydney have partnered to form the new Joint Center for Agricultural Robotics.
The first collaboration of its kind for WSU’s Center for Precision and Automated Agricultural Systems (CPAAS), the partnership joins WSU scientists’ expertise in innovative automation solutions for farms and orchards with pre-eminent research in robotics at the University of Technology Sydney’s (UTS) Centre for Autonomous Systems.
Biological Systems Engineering Faculty Claudio Stockle, Troy Peters, and Lav Khot received USDA-NIFA Funding as part of the State of the Washington Water Research Center (WRC) project titled “Technology for trade: new tools and new rules for water use efficiency in agriculture and beyond.”
