, terbuthylazine, and hexazinone are or have been used in the Edendale nursery, and metribuzin is attributed to horticultural operations (potatoes) in the area (Hughes 2000).
Deethyl atrazine also can be a by-product of propazine degradation (Thurman and others, 1998).
Detection frequencies of atrazine and deethyl atrazine in ground-water collected from central Alabama may indicate that an additional parent compound such as propazine also is degrading to produce deethyl atrazine; however, ground-water samples collected from central Alabama were not analyzed for propazine.
The primary herbicides used in both tillage systems were propazine
, atrazine, cyanazine, chlorsulfluron, and metolachlor, applied at labeled rates.
Chloro-s-triazines, introduced in the late 1950s, include atrazine (ATR), simazine, propazine, terbutylazine, and cyanazine (Worthing and Walker 1987).
Other chlorotriazines used in addition to or instead of ATR in the field, such as propazine and simazine, are similarly metabolized.
The median concentrations for cyanazine, metribuzin, and propazine
were all [is less than] 0.
In addition to atrazine, simazine, and propazine
