US EPA launches fumigant buffer calculator

The US EPA has launched an electronic Buffer Zone Calculator, which was developed to help soil fumigant applicators, growers, enforcement personnel and others determine the buffer zone distances required by soil fumigant product labels.

The EPA-developed Buffer Zone Calculator is specific to each fumigant product and is based on look-up tables on the product labels. In addition to calculating buffer zone distances, the calculator can also be used to quickly calculate buffer zone reductions through the use of credits and modifications to application parameters. Applicators will need to verify that the buffer zone results from the calculator are consistent with the buffer zone requirements on product labels. If there are any discrepancies, applicators should follow the label.
