Best Answer: The 1 st two guys missed what you said.. If you have a skirted tub I would definitely do under the skirt. It doesn t have to be all the way under, just the skirt edge. Since these skirts are made to be removed, you don t want to lock it in with tile.
Atrazine is thus said to have carryover, a generally undesirable property for herbicides. Glyphosate (Roundup) was introduced in 1974 for nonselective weed control. Following the development of glyphosate-resistant crop plants, it is now used very extensively for selective weed control in growing crops.
Atrazine biodegradation can occur by two known pathways: 1  Hydrolysis of the C-Cl bond is followed by the ethyl and isopropyl groups, catalyzed by the hydrolase enzymes called AtzA, AtzB, and AtzC. 2  Dealkylation of the amino groups gives 2-chloro-4-hydroxy-6-amino-1,3,5-triazine, the degradation of which is unknown.
