dimethoate; Chrysomelidae; nontarget organisms; spatial distribution; Fallopia convolvulus; mortality; fecundity; winter wheat; environmental exposure; adverse effects
Abstract:
... Direct insecticide deposition on adults of the chrysomelid beetle Gastrophysa polygoni L. was measured by use of fluorescent spray tracer. The beetles captured 1.3- to 2.5-fold the spray volume of an equivalent area of weed leaf surface. This disproportionate rate of exposure declined down through the crop canopy toward the ground. Spray deposition was measured for insects placed on both the upper ...

Abstract:
... The critical period of weed control is the portion of the life cycle of a crop during which it must be kept weed-free to prevent yield loss due to weed interference. The advent of herbicide-resistant canola (Brassica napus L.) varieties in western Canada has meant that there are now more options for postemergence weed control in canola, and this has prompted increased interest in identifying the o ...

Abstract:
... Field studies were carried out in 1989–1995 and 2006–2012 on plantations of sugar beet (Beta vulgaris L. subsp. vulgaris). During this period, 542 phytosociological relevés were made using the Braun-Blanquet method. In total, 46 weed species were found. In 1989–1995, the occurrence of 36 segetal species was reported. The highest cover indices were determined for Chenopodium album and Amaranthus re ...
