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.
So in higher-pH soils, the triazine and sulfonylurea herbicides persist longer, and more is available for plant uptake. (Some triazine and sulfonylurea herbicides do not persist and carry over, regardless of how high the soil pH is.) Low pH also can affect the persistence of both the triazine and sulfonylurea herbicides. Soil pH levels below 6.0 allow a more rapid dissipation of both these herbicide families. In acid soils, herbicides like atrazine become bound to soil particles, making them unavailable for weed control, but at the same time, they are chemically degraded more quickly.
