Formatted Abstract/Summary
A survey was undertaken in June 2008
in the main production areas for taro and banana on
Viti Levu, Fiji, to determine the frequency and density
of Mikania micrantha. There were significant
differences in the densities of the weed found in the
different areas. Within the taro areas, the mechanised
fields had the lowest densities (0.0 to 0.7 ± 0.4 plants
m-2) of the weed while the traditionally farmed fields
had the highest densities (0.9 ± 0.3 to 6.8 ± 2.8 plants
m-2). The banana areas had very high densities (3.0 ±
0.4 to 16.3 ± 2.0 plants m-2) of the weed. The higher
density of M. micrantha found in the traditional taro
fields as compared to the mechanised fields suggests
that the adoption of modern farming practices helps
manage and reduce densities of M. micrantha. However,
banana systems by their very nature, remain
very susceptible to M. micrantha invasion. Under
mechanised and traditional taro production, Cuphea
carthaginensis and Ageratum conyzoides were the
most frequently occurring weed species respectively.
However, in banana cultivation, M. micrantha was the
most common weed.
