| Abstract/Contents: | Discusses the potential effects of water quality on pesticide efficacy. States that "the two main water quality factors that determine the stability and overall efficacy of pesticides are water hardness/softness and pH. Addressing these two factors when tank mixing will help increase the success of a pesticide application." Explains that "water hardness is a measure of the total concentration of calcium (Ca2+) and magnesium (Mg2+), which often are expressed as parts per million (ppm) or milligrams per liter (mg L-1)...Hydrolysis, a process that breaks the bonds holding pesticides together, can reduce the life of a pesticide in a solution and is significantly affected by water pH. Extremes in spray tank pH can render a pesticide mixed in the morning useless in the afternoon." Concludes that "many factors affect the efficacy of pesticides applied to turf and ornamentals. Two factors, water hardness and pH, can be easily determined and accounted for when making pesticide applications." |
