Bagrada Bug Community Forum
Andrew Brait, Full Belly Farm
Paul Underhill, Terra Firma
Bagrada bug is an emerging invasive stink bug pest in California, which preferentially feeds on plants in the mustard family (i.e. broccoli, kale, cauliflower, cabbage). It is a sucking insect and can cause severe yield losses, especially when it attacks young plants. On January 12, 2021 UCCE hosted a forum for Yolo, Sacramento, and Solano county organic growers to discuss their experiences with fighting bagrada bug. Paul Underhill and Andrew Brait led the discussion.
Evaluating Biochar for Use in California Agriculture
Dani Gelardi, UC Davis
Jan 26, 2021
Biochar is often described as a silver bullet for increasing agricultural production while decreasing environmental impact. Due to its unique properties, biochar has the potential to address many pressing agricultural challenges, including fertilizer pollution, yield decline, vulnerability of soils to drought, depleted soil carbon stocks, waste management, and dependence on fossil fuels. Despite increased interest and investigation, there remain many questions about whether or not biochar can address these issues. In this 30-minute talk, Dani Gelardi will cover the basics of biochar: What is it? How is it made? What can it do? She will then review recent research from the UC Davis Environmental Chemistry Lab to illustrate how the basics may or may not apply to agricultural systems in California.
