JUST PUBLISHED: AI Runner Recognition in Strawberry Plants
Oct 4, 2024
JUST PUBLISHED: "A Two-Step Deep Semantic Segmentation and Object Detection Approach for Runner Recognition in Strawberry Plants" by Mojtaba Ahmadi, Abbas Atefi, Mohammadreza Ramzanpour, and John Lin. Strawberry farming in California faces a costly challenge: removing runners that divert plant resources away from fruit production towards producing daughter plants. Traditionally cut by hand, this labor-intensive task adds up to significant costs for farmers.
In collaboration with the California Strawberry Commission, this study introduces a two-step deep learning framework that combines semantic segmentation and object detection to accurately identify runners in strawberry fields. Successfully tested on three different cultivars, the AI system demonstrated high accuracy in runner recognition. This innovative technology paves the way for autonomous pruning robots, potentially reducing labor costs, increasing efficiency and boosting productivity for strawberry growers.

Center entomologist meets with Parabug for a drone demonstration
Oct 1, 2024
This past week our entomologist, Mohammad Amir Aghaee, met with former Strawberry Center graduate student Kiley Jensen to witness a demonstration of the Parabug drone delivering predatory mites on strawberries in Santa Maria.
It was an opportunity to discuss predatory mite research and methods with Bill Turechek, Andrew Molinar, and Roberto Mendoza (former Center undergraduate student) of the CSC, Sally Grey of Biobest, Daniel Ibarra PCA and Gabino Duran of Rancho Bonita. Kiley showed us how the drone is loaded and applied, and spoke about the laws surrounding drone use in California agriculture. Daniel Ibarra discussed the economics of using drones compared to normal hand releases. It was a great opportunity to hear new perspectives and make connections!
A change of pace from picking strawberries!

A little change of pace from picking strawberries... Some of our staff and students had the chance to pick some pumpkins this past week! We always enjoy connecting with other operations on campus and making the most of these opportunities. Happy Fall!
Samantha Simard successfully defends her master's thesis
Sep 24, 2024
CONGRATULATIONS to Sam Simard who successfully defended her master's thesis last week! Her thesis is titled "Survey of Soilborne Pathogens Infecting Strawberry in Oxnard, CA & Effect of Planting Date and Chill Treatment on Strawberry" and you can watch her presentation here: https://youtu.be/G31z_hLspdI?si=CJA1EuSAo7LMqoG_
Her thesis committee is comprised of Drs. Gerald Holmes (chair), Shashika Hewavitharana and Mark Hoffman (NCSU).
We're incredibly proud of her and we can't wait to see her grow in her role as Pathology Research Associate! 
Two Center students receive 2024 WRCCA Scholarship
Sep 20, 2024
Two of our student assistants, Sawyer Claussen and Olivia Bruns, received the 2024 WRCCA (Western Region Certified Crop Advisor) Allan Romander Scholarship Awards! Out of only four scholarships granted, we are incredibly proud that two of our own from the Strawberry Center have been recognized.
Scholarship applicants were selected using the criteria of academics, leadership, awards, professional development and their pathway to becoming a CCA. Congratulations Sawyer and Olivia for this well-deserved recognition!

Marina Gutierrez researches stress contributions to Macrophomina severity
Sep 3, 2024
Graduate student Marina Gutierrez researched how environmental stressors like drought and high salinity affect Macrophomina root rot in strawberries. By artificially infecting Fronteras and Sweet Ann strawberry cultivars with Macrophomina inoculum and subjecting them to various stress conditions, she found that drought was the most significant factor in plant mortality, followed by the high ECw stress. This research aims to better our understanding of how these stressors contribute to Macrophomina disease severity in strawberries.
She presented this year's data at our Field Day. Check out her handout here.
