The influence of weed seed predation by invertebrates and vertebrates was examined in relation to distance from hedgerows in maize fields of southwestern Michigan. Experiments were conducted in spring and winter and included five common weed species, i.e., velvet-leaf (Abutilon theophrasti), redroot pigweed (Amaranthus retroflexus), common lamb's-quarters (Chenopodium album), fall panicum (Pani...

Th e term “planta hortifuga“ refers to all cultivated plant species that have escaped from cultivation and grow spontaneously in diff erent natural, semi-natural or manmade habitats. List of “planta hortifuga” (Tab.1) consists of 120 taxa. Traits are given for each species: Raunkiaer’s life-form groups, taxonomic rank (family and species), geographical origin, use value, invaded habitat, invasi...

Clements, D. R. and DiTommaso, A. 2012. Predicting weed invasion in Canada under climate change: Evaluating evolutionary potential. Can. J. Plant Sci. 92: 1013 1020. Many weed species have already advanced northward from the United States into Canada, and their number threatens to increase with warming trends under climate change. For many weed species, this range expansion can be attributed to...

to evaluate the effects of sowing date, cultivars and herbicides on weed species control and soybean yield, a strip split plot layout in as a randomized complete block design with three replications was conducted in dasht-e-naz company sari-iran, in 2008. treatments included two planting dates (planting june 7th and 27th), soybean cultivars (bp, jk, 032, 033 and sahar) and herbicide application...

Weeds are a major problem in seeding rangeland and cropland to native grasses. However, many immature weedy forbs and grasses are palatable to cattle. Research was conducted using yearling cattle for weed control in big bluestem (Andropogon gerardii var. gerardii Vitman) seedings (1987, 1988) at Mead, Nebraska on a Sharpsburg silty clay loam (fine, montmorillonitic, mesic Typic Argiudoll) soil....

Plant Sci. 89: 969 975. A study was conducted over a 3-yr period (2003, 2004, and 2005) to evaluate the effect of reduced herbicide rates 20, 40, 60, 80, and 100% of the manufacturer’s recommended rate (MRR) ...
