In this episode, Sarah Marsh Janish talks with Dr. Lina Bernaola, an assistant professor in the Texas A&M AgriLife Research Department of Entomology, to give a rundown on rice delphacid, a pest that is ravaging the Southern Rice Belt and is a vector of Rice Hoja Blanca. While it is not present in CA yet, it's important to be aware of potential threats to the US Rice industry

In this episode, Luis Espino and Sarah Marsh Janish give a rundown on stem rot, one of the main diseases of rice in California. One disease that can be found in practically every rice field is stem rot. This fungus causes the tillers to rot at the water level and, when severe, it causes blanking and lodging.

Sarah Marsh Janish sits down with Mia Avila and Oscar Deleon, Jr., who spent summer 2025 with the UCCE Rice Team as part of Chico STEM Connections Collaborative, a collaborative undergraduate research experience at California State University Chico. CSC² is an innovative program working in collaboration with other California State Universities throughout the state to coordinate and integrate project data into one of the largest and most comprehensive evaluations of best practices found in the nation. CSC² serves educationally disadvantaged students and, to the extent possible by law, emphasizes participation by students from groups with low eligibility rates for four-year institutions.

Mia and Oscar, as members of this collective, spent their summer working on various research projects with the UCCE Rice Team, as well as performing their own supervised rice research throughout the summer.

Mia Avila Bio: My name is Mia Avila, I’m a 4th year undergraduate student at CSU Chico studying Plant & Soil Science, and I’ve grown up in the north state all my life.

Oscar Deleon Bio: My name is Oscar Deleon Jr., and I’m a second-year Plant & Soil Science major at CSU Chico. I transferred here from the Coachella Valley, specifically Indio, and I’m passionate about anything agriculture-related.

Together, the UCCE Farm Advisors seek to provide relevant, topical research-backed information relating to CA rice production.

We're doing a rerun episode today: Luis Espino and Sarah Marsh will be talking about Rice Armyworm Monitoring Program and the second generation of armyworms in rice. We're using this episode as the second peak of armyworms is approaching quickly!

Two true armyworm generations occur in rice; moths fly in spring and early summer, laying eggs in rice fields and surrounding vegetation. The larvae that emerge feed on rice foliage. A second moth flight occurs in mid-summer, followed by larvae feeding on rice foliage and panicles.
