Linquist, Al-Khatib and teams discuss new varieties, pests, possibilities
New varieties of rice that offer more effective weed control with less herbicide were showcased by UC Davis Department of Plant Sciences researchers at the recent Rice Field Day north of Yuba City in California's Central Valley. Amid the West's ongoing drought, green rice with heads full of grain stood tall and lush in some test plots, while dry, brown stubble poked up in others. Department researchers discussed the impact of letting ricelands go fallow, including potential for pest control and ways to conserve soil moisture.
The event was hosted Aug. 31 at the Rice Experiment Station.../h3>

In California rice, herbicide resistance has been documented in Echinochloa spp. since the early 2000's. Recent reports of uncontrolled grasses, as well as possible new species or biotypes have precipitated renewed...

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. Previous company trials have indicated that Loyant provides good control of...

In 2020, we conducted a small screening with a set of 10 watergrass samples (collected in 2018) from across the valley, trying to see if we could get an idea of what herbicides controlled the different species/biotypes. The results from those 10 samples indicated that Clincher, propanil, and Regiment, as well as Cerano, had the best.../span>
