The Bait Surcharge Program: Research Improves Zinc Phosphide Use for Vole Control in Alfalfa

This paper describes several unexpected benefits of rodenticide-registration research funded by The California Bait Surcharge Program. An enclosure-type study was conducted to determine efficacy of single, preand test-bait broadcasts (10 lb./ac.) of 0% and 2% zinc phosphide (ZqP,, CAS #1314-84-7) steam-rolled-oat (SRO) groats to control voles (Microtus spp.) in alfalfa (Medicago sariva). Unexpe...

An Overview of Recent Ground Squirrel Bait Registration Research Supported By the California Bait Surcharge Program

The California Department of Food and Agriculture Rodent Bait Surcharge Program is actively funding studies to develop and register safe, effective and practical ground squirrel baits. Under this program, Genesis Laboratories has conducted eight studies since 1994 designed to fulfill registration requirements for existing baits and to develop new baits. Areas of research include field efficacy,...

Zinc Phosphide Poisoning

Zinc phosphide has been used widely as a rodenticide. Upon ingestion, it gets converted to phosphine gas in the body, which is subsequently absorbed into the bloodstream through the stomach and the intestines and gets captured by the liver and the lungs. Phosphine gas produces various metabolic and nonmetabolic toxic effects. Clinical symptoms are circulatory collapse, hypotension, shock sympto...
