SJC and Delta Field Crops

Please see this article on the UC Rice Blog for an update on armyworm populations. We will continue to monitor traps in the Delta through mid-September, and we will plan to monitor populations next season.

A land manager recently contacted me with questions about overseeding alfalfa. Her alfalfa stand is diminishing but not to the point of giving up on it.

Please mark your calendar with the following fall outreach events.

I recently visited a bean field in the southern part of the county with a PCA. From a distance, the beans in certain areas of the field appeared to be drying up and dying. A closer look showed that the leaf margins were drying up first before the whole plants declined.

I have received armyworm traps from UC Davis entomology specialist, Larry Godfrey, and UCCE farm advisor, Luis Espino, to monitor populations in San Joaquin County rice fields. Luis has described 2016 armyworm pressure in a recent posting on the UC Rice Blog.
