Rooting out parthenium: A milestone moment for sustainable weed management in Pakistan
Parthenium hysterophorus, commonly known as parthenium or “famine weed”, is one of Pakistan’s most damaging invasive species. It spreads aggressively, suppresses crop productivity, threatens grazing lands, impacts biodiversity, and poses serious health risks to humans and livestock. Over the past decade, CABI has led a comprehensive, science-based campaign to address this threat. Now, as the…
Horizon scanning for climate-driven pest threats can prevent biodiversity loss
On International Day for Biological Diversity, CABI’s Dr MaryLucy Oronje looks at horizon scanning and pest preparedness – approaches that help prevent the spread of invasive species, a major threat to biodiversity. Horizon scanning for invasive pests is crucial for preventing biodiversity loss. The early identification and assessment of emerging threats allow ecosystems to be…
How does parthenium weed impact maize crop production?
Parthenium hysterophorus, or parthenium weed, is highly invasive in many parts of the world. It is native to Central and South America but is now found in Asia and Africa, among others. In Australia, it has caused millions of dollars in crop yield losses. This is because the weed can produce prolific seeds, germinate, and…
Biocontrol agent released to safeguard crops from parthenium weed in Pakistan
Invasive plants can be extremely harmful to crops. “Famine weed” or parthenium is one such plant. Native to tropical America, it was accidentally introduced to several countries. In Pakistan, the weed now covers thousands of hectares of agricultural and rangeland. And it poses an economic burden to farmers.
Training workshop focuses on rearing of stem boring weevil to fight noxious parthenium weed in Pakistan
Parthenium hysterophorus is a highly destructive weed that has crossed continents, and is spreading rapidly in both rural and urban landscapes across Pakistan. A variety of methodologies have been used to control its spread but no single management option is adequate to manage parthenium. Therefore, there is a need to integrate various management options.
