AMERICAN WIGEON MORTALITY ASSOCIATED WITHTURF APPLICATION OF DIAZINON AG500
American Wigeon (Anas americana) Science Article 1 abstract Nine fairways of a golf course located in Bellingham, Washington were treated with diazinon AG500 at a target application rate of 2.2 kg active ingredient (Al) per ha.
