PROPOSED LABEL CHANGES
The US EPA has proposed a series of dramatic changes to rodenticide labels which will significantly change how rodenticides are used in alfalfa, pasture, and many other crops (orchardes, vineyards).
Among other restrictions,
- All rodenticides for field applications will be restricted-use (new requirements for equipment, training)
- Above-ground applications eliminated

A new caterpillar was found this fall on alfalfa in the Palo Verde Valley of California and several other alfalfa growing areas of western Arizona.

The initial finding of the ‘dot-lined angle' caterpillar (moth) was reported to UCCE in mid-October by a highly experienced pest control advisor (Richard Wellman), who had collected it in several fields in the Palo Verde Valley but realized it was an unfamiliar species. UCCE advisor Michael Rethwisch (Riverside County, CA) identified the species as the dot-lined angle (Psamatodes abydata), with this identification confirmed by Marc Epstein at the California Department of Food and...

Sudangrass (Sorghum bicolor L.) is a type of sorghum which is widely grown for hay, greenchop or grazing systems. Typically over 50,000 acres of sudangrass are grown for hay in the Imperial Valley of California, much of it exported to Japan.
However, sudangrass (and sudan-sorghum hybrids) can be grazed or fed as greenchop to livestock particularly beef animals or used as a vigorous cover crop. What are the risks of feeding sudangrass to livestock?
Is Grazing Safe? A couple of questions have come up about grazing sudangrass including: 1) grazing sudangrass stubble after harvest, and 2) grazing sudangrass in a cover crop. Is this a safe practice? Maybe, but pay attention! Care is...
