The article “IPM and Pollinators” in the April 2015 issue of IPM Insights incorrectly stated that neonicotinoid pesticides are not soluble in water. In fact, the solubility of imidacloprid in water is 610 milligrams per liter at 20 degrees Celsius. See http://npic.orst.edu/factsheets/imidacloprid.pdf and Hladik, M.L., D.W. Kolpin and K.M. Kuivila. 2014. Widespread occurrence of neonicotinoids in streams in a high corn and soybean producing region, USA. Environ. Pollution 193:189-196. Our thanks to readers who spotted this error.
