- Title
Loss of enhanced biodegradation of 2,4-D and MCPA in a field soil following cessation of repeated herbicide applications.
- Authors
Smith, A.; Aubin, A.
- Abstract
The article presents a four-year field study which investigates the ability of soils from plots in Saskatchewan to retain their 2,4-dichlorophenoxyacetic acid (2,4-D) and 4-chloro-2-methylphenoxyacetic acid (MCPA) populations. The study uses laboratory persistence studies and the most probable number (MPN). Results show that the soil microflora maintain the ability to rapidly degrade 2,4-D for at least 204 weeks while its ability to degrade MCPA is maintained for between 48 and 100 weeks.
