Validation of a standard field test method in four countries to assess the toxicity of residues in dung of cattle treated with veterinary medical products
Registration of veterinary medical products (VMPs) includes the provision that field tests may be required to assess potential non‐target effects associated with the excretion of product residues in dung of treated livestock (Phase II, Tier B testing).

Diversity in seed production characteristics within the USDA-ARS limnanthes alba germplasm collection
Meadowfoam (L. alba) seeds are a source of long-chain fatty acids which are stable under diverse conditions. The fatty-acid composition makes this seed oil valuable for use in cosmetics, lubricants, rubber additives, and plastics. While a few meadowfoam cultivars have been developed, high-yielding germplasm is required for further crop improvement. The objective of this study was to evaluate ...
