Abstract

Many methods have been developed to control accidental contamination from liquid pesticides. They comprise “dry-break” or dripless connectors, and closed systems. The latter result from progressive legislation in California that restricts the open pouring of liquid pesticides.

The usual method for extracting pesticides from containers employs a removable, reusable probe, which is always contaminated. A new means to avoid contamination, the Universal Closed System, currently in development, uses a built-in disposable probe and valve in each container. The valve is dripless and is always closed unless activated by a unique extractor.

Field testing has shown the system to be safe, reproducible, and easy to use. Anticipated costs are at acceptable levels.
