University of California Cooperative Extension, in collaboration with the Agronomy Research and Information Center at UC Davis, has produced a short video which explains how to collect seed to make sure that if you do submit weed seed for testing, you get back accurate results.

The form, which must accompany any submitted weed seeds, can be found on the UCANR Rice Website
