The UCCE Rice Team has developed a series of Factsheets to simplify and convey information about important topics that we find we are frequently discussing with growers and PCA's. Each fact sheet is 2 pages long, back to front.
A new herbicide is available this year for use in California rice: RebelEX, manufactured by Corteva. It is a premix of two other well-known herbicides: Clincher and Granite SC, both from Corteva. The active ingredients in RebelEX are cyhalofop (same as Clincher) and penoxsulam (same as Granite SC).
This year we are conducting a study at the Rice Experiment Station to look at lodging differences between M-206 and M-105. There has been anecdotal evidence that M105 is more susceptible to lodging than M-206. We want to quantify this and see if we can manage N to reduce lodging if need be.
While checking traps recently, I noticed a lot of activity in the water in several recently flooded fields. A quick glance into the water might make you believe that tadpole shrimp is present in large numbers, or even perhaps that a treatment did not work.
Following my blog post about a week ago about using urea or aqua-ammonia (aqua), a number of people have been asking to see the data. The study was conducted in 2017 at the Rice Experiment Station. Aqua and liquid urea were applied at three rates (50, 100 and 150 lb N/ac).
