The California Department of Pesticide Regulation is currently reviewing the use of Transform (sulfoxaflor) for insect pest management in alfalfa hay production. A decision on whether to register Transform with a label for use in California alfalfa is expected to occur by the end of 2020. The registration of Transform has been so far deferred due to concerns of potential impacts on pollinators. Transform currently has a full EPA label for use in alfalfa hay in all other states, but not in California.

A virtual forage and alfalfa field day - our insect pest contribution
This year, the Kearney Research and Extension Center Alfalfa and Forage Field Day went virtual. Attendees did not get the chance to look out over lush fields of alfalfa or towering plantings of sorghum, but they get did an update on ongoing work in alfalfa and other forages. Our team put together a rapid-fire video to discuss what are typically the key insect pests in California alfalfa: summer worms, alfalfa weevils, and aphids.

We all recognize human health as a goal, but healthy soils is a key goal for farming operations, since healthy soils frequently result in higher yields and economic returns over time. "Health" is often defined with a range of properties including high fertility, good water-holding capacity and drainage, long-term productivity, and sustaining organic matter content.
