A land manager recently contacted me with questions about overseeding alfalfa. Her alfalfa stand is diminishing but not to the point of giving up on it. Rachael Long, Yolo County farm advisor, Dan Putnam, UC Davis alfalfa specialist, and Mick Canevari, San Joaquin County farm advisor emeritus, presented on this topic at the Alfalfa and Forage Symposium a few years back and wrote up a proceedings paper on this topic. Additionally, there is a production manual which is available...

OK - those millions of pretty yellow and white butterflies that have fluttered over fields and ditches and smeared across your windshields - what are they?
Alfalfa fields appear more yellow and white than green with outbreaks of alfalfa caterpillar (Colias eurytheme) butterflies in some fields this year in the Sacramento Valley. There have been massive populations observed throughout the Sacramento and San Joaquin Valleys.
Although these butterflies are pretty, in this case looks are deceiving. High numbers of butterflies are a warning sign, as they can be serious pests of alfalfa. The larvae, green caterpillars with a white strip along their sides, consume entire leaves and can strip a plant,...

Last year Klamath Basin alfalfa growers had to deal with an outbreak of the blue alfalfa aphid (BAA) and the associated cost of insecticide sprays as well as the yield loss. Fortunately, aphids have not been a problem this year. This may be due to the relatively wet year we have had (especially this spring) providing more favorable conditions for fungi that can keep aphids in check.
