It's that time again! If you would like to submit seeds for herbicide resistance testing, many weed species will be maturing right about now.

The UCCE Rice Team is conducting a field survey to collect watergrass samples over the next few weeks.

This field day is open to the public. Please share broadly to those who may be interested in attending.

I have been getting quite a few questions regarding blast, mostly from Glenn and Colusa counties. It seems that 2020 will be a year with significant blast pressure. Under California conditions, blast can be observed in fields before heading. This occurrence is referred to as leaf blast.

The period between panicle initiation (PI) and heading is critical with respect to grain formation. During this time, cold temperatures can result in pollen sterility as the plants go through meiosis. Pollen sterility results in blanking. Nighttime temperatures below 58 oF can result in sterility.
