Summary
Winged primrose willow is an invasive weed that was identified in Butte County rice fields in 2011. Most infestations were along borders of fields and canals; however, this weed can thrive in the flooded environment within rice fields. Winged primrose willow can disperse through seeds and plant fragments floating in the irrigation water and tillage and harvest equipment.
Greenhouse tests showed that winged primrose willow can be controlled with rice herbicides. Early, into-the-water applications of Bolero Ultramax, Cerano or Granite GR effectively killed young plants. Foliar applications of Sandea and...

During the 2000s, organic milk production was one of the fastest growing segments of organic agriculture in the United States, according to a USDA Economic Research Service publication Characteristics, Costs, and Issues for Organic Dairy Farming. In 2008, about 3 percent of the nation's cows were managed organically.
Among the conditions necessary for a cow to produce organic milk, she must eat only organic feed or browse on organic pasture for at least the previous 36 months. However, dairy producers have found that producing or sourcing organic feed – which must be grown without synthetic fertilizers, insecticides or herbicides – is...

Some data from over 15 years ago may help people better asses the damage from phenoxy herbicide drift in the San Joaquin Valley this year. This data is only for one trial in one year, but shows the range of damage which can occur in cotton. The yield losses were the greatest when the cotton plants show continued phenoxy symptoms on new growth all season long.
Thousands of acres of cotton in the Sacramento Valley were damaged by phenoxy herbicide drift in 1995. Cotton had not been planted on a large acreage in the Sacramento Valley since being planted in the 1920’s. This widespread damage continued in 1996 and 1997 and only stopped when the phenoxy herbicde manufactures severely restricted...
