"The 2010 RUFORUM Biennial Conference was the second in the series. The main objective of the Biennial conferences is to provide a platform for agricultural research for development stakeholders in Africa and beyond to actively exchange findings and experiences, while at the same time learning lessons towards improving performance of the agricultural sector and ultimately people’s livelihoods. The biennial conference is RUFORUM’s most comprehensive meeting for the diversity of stakeholders in agriculture. It is especially dedicated to graduate students and their supervisors, grantees in RUFORUM member universities and alumni. It is a platform for peer review, quality control, mentorship, networking and shared learning. This record contains an extended abstract accepted under the theme of Pests"
Distribution and potential invasion of Opuntia spp. on selected Namibian sites
Abstract:
The distribution, density and size attributes of an alien invasive
species, Opuntia spp., were assessed on each of north, west,
south and eastern communal and commercial farming sites in
Namibia. A chemical control trial on this species was carried
out with two chemicals, Monosodium Methyl Arsenate (MSMA)
and Glyphosate. The density of Opuntia in Namibia was found
to be sparse. Most populations had a significantly higher juvenile
proportion, indicating potential for aggressive invasion of the
species. MSMA treatment yielded the best results. Landowners
are advised to treat Opuntia spp. chemically while densities
are still low.
La distribution, la densité et les caractéristiques de taille d’une
espèce envahissante étrangère, appelée “ Opuntia spp.” ont
été évaluées sur chacun des sites agricoles commerciaux et
communaux du nord, de l’ouest, du sud et de l’est de la Namibie.
Une épreuve de contrôle chimique sur cette espèce a été
effectuée avec deux produits chimiques, arséniate méthylique
monosodique (MSMA) et glyphosate. Il s’est avéré que la
densité d’ Opuntia en Namibie est dispersée. La plupart des
populations ont eu une proportion juvénile sensiblement plus
élevée, indiquant la possibilité d’une invasion agressive de
l’espèce. Le traitement avec MSMA a donné les meilleurs
résultats. Des propriétaires fonciers sont avertis de traiter cette
espèce chimiquement pendant que les densités sont encore
basses.
