We are excited to announce that our Alfalfa IPM YouTube video titled, “Identification of parasitized alfalfa caterpillars and armyworms”, was a finalist in the annual national Entomological Society of America YouTube Contest this week in Minneapolis, MN.
This video shows how to monitor alfalfa insect pests and their natural enemies to help make informed management decisions on pest control in alfalfa production. Step-by-step instructions are presented on how to identify parasitized caterpillars under field conditions and how to use this information for managing caterpillar pests, to help reduce pesticide use and production costs in alfalfa.
Take a look at this 2.4-minute Alfalfa IPM video that was produced in...

UC IPM is pleased to announce the availability of new tools for IPM in alfalfa. As part of the California Department of Pesticide Regulation's contract to evaluate critical uses of chlorpyrifos in alfalfa, an innovative Decision Support Tool (DST) was developed to support insecticide decision making around key insect pests. The tool supports the use of chlorpyrifos (Lorsban and other generic products) for those times and situations where it makes for the best practice and provide multiple alternative practices and AIs for other situations. This decision support tool is embedded in the UC IPM Pest Management Guidelines (PMG) or

Tempted to ‘sheep off' or graze your fall growth after a drought year? You'd better be careful!
Many fields of alfalfa have been ‘dried down' this year, but most will start growing again this fall when rains return. Farmers and grazers are often tempted to graze those fields in the fall/winter period when green growth reappears in October-February.
An observational trial was conducted last year in Yolo County to evaluate the impact of deficit irrigation on alfalfa stands, including those grazed by sheep in the fall.
Stand counts were taken in four alfalfa fields in October 2014 in fields that had not received any water throughout the growing season due to zero water allocation from the...
