1 Swish 1 to 2 teaspoons of a vegetable-based oil (coconut, sesame, or olive) in your mouth for 20 minutes, spit it out, rinse with warm water, and brush well after rinsing, says, Marc Lowenberg, DDS, a dentist at Lowenberg, Lituchy & Kantor in New York City.
Atrazine is the most widely-used conservation tillage herbicide in corn and is a critical rotation product to manage weed resistance. Conservation tillage makes cropland much less vulnerable to soil erosion, which is reduced by as much as 90 percent when compared to intensive tillage.
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.
