Bioeconomic model of weeds in pastures

Agro-Ecosystems, 1979
Interactions between weeds, pastures and grazing animals are reviewed. It is argued that the economic interpretation of effects of weeds should be based on a farm unit. The weed, Silybum marianum, is examined in relation to a specific farming system. Within a wholefarm framework, two of its effects, competition and reduction of accessibility of pasture,

Canopy and Chemistry of Pasture Weeds

Weed Science, 1980
Morphological and chemical characteristics of 11 warm season pasture weed species were defined. Goldenrod (Solidago altissima L.) was significantly taller and common ragweed (Ambrosia artemisiifolia L.) had the largest canopy diameter of the 11 species studied. Species ranged from 14 to 134 cm in height with canopy diameters of 25 to 70 cm.

The first consideration about poisonings is the possibility of one being present. In acute poisoning, whether it is plant or chemical, the first tip-off, of course, is single or multiple death and illnesses that ...

Weed Management in Crop-Pasture Rotations

1989
On wheat-sheep farms in the south-west of Western Australia, pasture production in winter is a major limiting factor for the sheep enterprise. This paper describes an economic evaluation of reducing herbicide usage in crops below recommended levels to increase subsequent pasture production in pasture-crop rotations.

Weeds of pastures and meadows in Japan

1982
In Japan, from ancient times, semi-natural grassland dominated by grass species such as Miscanthus sinensis, Sasa spp., Zoysia japonica and Pleioblastus distichus var. nezasa has been maintained under moderate grazing, mowing or periodic burnings. These grass species are utilized for forage, thatch, charcoal bags and litter. Z.

Chemical weed‐control and pasture productivity

Journal of the Science of Food and Agriculture, 1954
AbstractThe principal weeds of grassland are unwanted grass species, and, although some possibilities are indicated, no chemical method for their removal in farming practice is yet available. The hormone weedkillers may be used for the control of a number of broadleaved weeds.
