Legislators learn about Steam Weeder and CropManage at UC Innovation Day

Michael Cahn, center, and Aparna Gazula explain how the decision-support tool CropManage helps farmers save water and fertilizer.

On May 8, the University of California hosted an emerging science and technology innovation day at the UC Center in Sacramento. The UC inventions showcased at the event were examples of how academic research translates into real-world applications that benefit Californians and the world.

Of the 25 innovations featured, UC ANR was represented by two inventions – Steam Weeder and CropManage. Innovations were displayed for legislators and staff for most of the day.

During the Fireside Chat on innovation, UC regents Rich Leib and Lark Park listen as Assemblymember Jacqui Irwin speaks.

Vice President Glenda Humiston also participated in the Fireside Chat, where over lunch UC Board of Regents Chair Rich Leib and Regent Lark Park led a conversation on innovation, clean energy and biomedical discoveries.

Steam Weeder is a machine designed to inject steam into the soil, offering a safer alternative to chemical pesticides. By heating soil to a precise temperature, this device effectively eliminates pests by thermally rupturing their cell walls, protecting crops and reducing the need for hazardous chemicals. This innovative machine reduces weeds by 85% and decreases the incidence of soil-borne diseases. Steam Weeder is ideal for farmers managing row crops, vineyards and orchards, especially those facing increased costs and strict regulations for chemical fumigants. The Steam Weeder, developed by Steven Fennimore, UC Davis professor of Cooperative Extension and extension specialist for vegetable weed management, offers an effective, safe and economical solution for large-scale weed management.

CropManage is a web-based tool developed by UCCE Monterey County farm advisor Michael Cahn to help farmers manage and make informed decisions for efficient crop production. Using years of research and field studies, CropManage software integrates data from satellite imagery, water stations, soil maps and field sensors to tailor specific recommendations for irrigation and fertilization of crops. CropManage provides water and fertilizer management guidance while maximizing production efficiency.

UCCE Santa Clara County small farms advisor Aparna Gazula and grower Mark Mason participated in the event to explain to legislators and staff how CropManage helps growers save water and fertilizer.
