Control of weeds has always been a major economic cost in subtropical fruit production because of favorable climate that allows for weed germination and year-round growth. The use of chemical weed control has increased dramatically due to labor costs, equipment costs, product costs and availability, the shift to more narrowly spaced tree rows, and installation of low volume irrigation systems that prohibit the operation of mowing or tillage equipment under the tree canopy area (Futch 2001).

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...

Oregon leads the United States in the production of Christmas trees, with almost 8.5 million trees sold in 2015. Weed control is essential in Christmas trees to reduce competition for moisture and nutrients, allow fast and robust tree growth, and ensure growers top prices for high-quality trees. Research is needed on weed management in Christmas trees in the West to ensure they remain economically competitive. Herbicides are the primary weed control option for Christmas tree growers, but options are limited, and herbicide-resistant weeds challenge weed control. Herbicide resistance has increased weed management costs in Christmas trees; growers must now turn to mixtures of herbicides or planned rotations. Increased diversity of...
