Wisconsin Pesticide Applicator Practice Test

A highly soluble pesticide is poorly adsorbed and more likely to leach because it doesn't bind well to soil particles and can easily move through the soil and potentially contaminate groundwater and other water sources. Options A and C are incorrect because highly soluble pesticides are not more likely to bond with soil particles and are also not less toxic. Option D is also incorrect because the solubility of a pesticide does not necessarily determine its toxicity.
