Wood preservatives dominate Maryland pesticide use
Wood preservatives accounted for 68% of the 16.5 million lbs (748 tonnes) of pesticides applied in the US state of Maryland in 2011, according to the latest use survey by the USDA's National Agricultural Statistics Service. The survey, which was conducted in 2012, was the first to be commissioned by the Maryland Department of Agriculture (MDA) since 2004 because of budget restrictions, the MDA notes. Herbicides accounted for 21% of total pesticide usage, with insecticides making up 5% and fungicides 3%. Fungicide use had declined by 84% from 2004, while herbicide use had dropped by 46% and insecticide use by 5%, the MDA points out. The survey covered farmers, private applicators, commercially licensed businesses and public agencies that are permitted by the MDA to apply pesticides.
