Effects of selected pesticide application routines on pest and beneficial arthropods on soybean in Mississippi
Environmental Entomology 12 (2), 552-557
Abstract: The impact of a nematicide-insecticide (aldicarb), two postemergence herbicides, (acifluorfen and bentazon), a fungicide (benomyl), and an insecticide (methyl parathion) applied alone or in scheduled treatment routines on pest and beneficial arthropod populations was determined on soybean, Glycine max (L.) Merrill, in south Mississippi during 1980 and 1981. Arthropod populations in soybean were not affected by pesticide routines including aldicarb, acifluorfen, bentazon, and benomyl. However, pest and beneficial arthropod populations were reduced significantly after application of methyl parathion, with resurgence of populations by days 7 and 16 posttreatment, respectively. The acifluorfen and acifluorfen + benomyl + methyl parathion-treated soybean sustained less defoliation than the untreated soybean during 1980; no differences in defoliation were recorded among treatments in 1981. Soybean treated with acifluorfen + benomyl + methyl parathion yielded more than untreated soybean and soybean receiving routines in which benomyl was not included in 1980. Yields did not differ among treatments in 1981.
