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.
It's estimated that atrazine can increase crop yields by up to six percent. Atrazine has also been used in conservation tillage systems to control weeds and reduce soil erosion. As late as 2002, it was estimated that atrazine was the most commonly used herbicide in the world with applications in 80 countries. But studies around that time showed that atrazine was dissolving into water in the fields and was showing up in streams and underground drinking water supplies all over the world.
