SJC and Delta Field Crops

As the Covid-19 pandemic persists, and as government and University recommendations maintain that we should social distance, the SJC and Delta Field Crops Meeting will now be VIRTUAL. The meeting will still take place THIS Friday, January 14th from 8am to noon.

UC Cooperative Extension will host the SJC and Delta Field Crops Meeting on Friday, January 14, 2022 from 8:00am to 12:00pm. The meeting location is the Cabral Agricultural Center in Stockton (2101 E. Earhart Ave., Stockton, CA 95206).

From 2019-2021, we conducted trials to evaluate the efficacy of a new herbicide product called Loyant (florpyrauxifen-benzyl; group 4 herbicide; Corteva Agriscience) in Delta drill-seeded rice. Loyant is registered in rice growing states in the southern US but would be a new chemistry in California.

In 2021, rice acreage in the Delta, south of the Yolo Bypass, was roughly 6,600 acres. Most of the Delta acreage is in San Joaquin County, with a few hundred acres in Sacramento County. Delta rice acreage has been steadily increasing over the last several years (Table 1).

In a previous blog post, I introduced a project about using nitrogen (N) rich reference zones in wheat. The goal of the project is to show how N-rich reference zones can be used to guide N fertilization in small grains, to increase crop productivity and N use efficiency.
