Southern Redcedar and Southern Magnolia Wood Chip Mulches for Weed Suppression in Containerized Woody Ornamentals

Weed Control in Southern Hardwood Nurseries

In the South, most nursery managers have relied on methyl bromide for weed control in hardwood seedbeds. When methyl bromide is no longer available, handweeding times will likely increase unless management regimes adapt to the change. Some nursery managers will increase use of both sanitation practices and herbicides. Although several herbicides are registered for use on hardwoods, some can inj...

Giant flowers of Southern magnolia are hydrated by the xylem.

Flowering depends upon long-distance transport to supply water for reproductive mechanisms to function. Previous physiological studies suggested that flowers operated uncoupled from stem xylem transport and received water primarily from the phloem. We demonstrate that the water balance of Southern magnolia (Magnolia grandiflora) flowers is regulated in a manner opposite from that of previously ...

Weed Resistance to Herbicides in Rice Fields in Southern Brazil

Effect of Weed Control with Fibre Mulches and Herbicides on the Initial Development of Spruce, Birch and Aspen Seedlings on Abandoned Farmland

Post-planting weed control methods on abandoned farmland were studied in three fi eld trials in southern Finland using a completely randomized design with four treatments and 30 to 40 replications. Mulches of 60 × 60 cm [sheet mulch – strips of plane waste and plastic fi bre, newspaper – waste paper slurry, wood chips, pure wood fi bre slurry], herbicides [i.e. glyphosate or terbuthylazine alon...

Effect of living mulches and conventional methods of weed control on weed occurrence and nutrient uptake in potato

The aim of the study was to determine the biomass, abundance and species composition ofweeds, as well as macroelement uptake in potato weeded using mechanical, mechanical–chemical and mechanical control combined with the sowing of living mulches of white mustard,common vetch, Persian clover and tansy phacelia. Abundance and biomass of the weeds was themost effectively limited by the mechanical ...
