The US EPA has issued guidelines to enable pesticide registrants to comply with the new standards for pesticide containers and containment structures that were finalised last year. The Agency has established standards for refillable and non-refillable containers, including design specifications for rinsing, durability and standardised closures. The Pesticide Registration Notice is available on the EPA's website at: http://www.epa.gov/PR-Notices/pr2007-4.pdf
