The University of California Division of Agricultural & Natural Resources will be holding the California Alfalfa & Grains Symposium this year in Long Beach CA on December 10-12, 2014.
- Listen to expert speakers.
- Visit with your colleagues at the evening receptions.
- Stop by the exhibit area to see the latest on alfalfa and forage products and services.
- Receive Symposium Proceedings
California grows over 3 million acres of alfalfa and other forage crops. The Symposium will be a comprehensive meeting to focus on critical issues related to alfalfa and forage crops, particularly global issues, economics, and practical 'how to' talks on crop production techniques.
The blue alfalfa aphid, Acyrthosiphon kondoi Shinji was first identified by entomologists in the spring of 1975 in the Imperial Valley of California. Since then it has become widespread throughout the state and has become established in Arizona, Nevada, New Mexico, and as far east as Kansas and Oklahoma. Both adults and nymphs feed on photosynthetic fluids from the leaves and stems of the alfalfa plant. Low to moderate populations of blue alfalfa aphid may cause little to no visible yellowing of plants. Blue alfalfa aphid feed in the new growth, at the tips and young leaves. After prolonged feeding, leaves will eventually turn yellow, starting at the veins, leaves will curl and wilt, and turn necrotic...

Hang onto your hats - A decision by USDA yesterday paves the way for commercialization of the second genetically-engineered (GE) trait in alfalfa in 2015 – one with a quality feature.
Reduced Lignin in alfalfa may improve milk production per ton, and potentially allow growers to harvest later, increasing yields.
The USDA-Animal and Plant Health Inspection Service (APHIS) has declared a “FONSI” – finding of no significant impact for the KK179 trait in alfalfa, which confers reduced lignin levels in the plant, effective 10 November, 2014.
This formally deregulates the low lignin GE...
Alfalfa (Medicago sativa L.) has been cultivated in California since it was first introduced from Chile in 1850. Alfalfa yields can be reduced by several species of insects, such as leafhoppers in the genus Empoasca. These leafhoppers are highly polyphagous and capable of successful reproduction on over 200 plant species in 25 different families. In alfalfa hay in California there is a complex of three species of Empoasca leafhoppers (ELH) that are nearly identical in appearance and behavior. These include the potato leafhopper, Empoasca fabae (Harris), the garden leafhopper, Empoasca solana DeLong, and the Mexican leafhopper,.../h3>

We are collecting email addresses to create an electronic mailing list for meeting announcements. The cost of printing and mailing newsletters has become prohibitively expensive, so we are migrating to electronic delivery. The list will not be used to send information other than meeting-related announcements. If you didn't provide your email at the meeting and would like to be added to the list, please send...
