Strengthening vegetable value chains in Pakistan

Small-scale vegetable farmers in Pakistan encounter a number of issues that compromise their sustainable livelihoods; particularly for women and youth. Through the project, an alliance of selected organizations aimed to improve the livelihoods of rural communities in Sindh and Punjab by strengthening selected horticultural value chains and promoting sustainable production and marketing opportunities.

Biological control of oxeye daisy

Although closely related, Oxeye daisy is an invasive weed in places like North America and Australia, while Shasta daisy remains a garden favourite, especially in North America. CABI is investigating whether specialist natural enemies from oxeye daisy’s area of origin in Eurasia could be introduced in North America and Australia as biological control agents. In North America the popularity of Shasta daisy makes this a challenge because any introduced agent must damage oxeye daisy but not Shasta daisy.

Assessing a biocontrol agent for Jatropha gossypiifolia

Jatropha gossypiifolia (bellyache bush) is a major invasive plant in northern Australia. Previous biocontrol efforts have focused on insects but the Australian Government is now also keen to explore fungal pathogens. As experts, CABI is carrying out safety and efficacy experiments with the rust pathogen Phakopsora arthuriana using a strain originating from Trinidad. Results will help the Australian authorities decide whether this rust is suitable for biocontrol of J. gossypiifolia in Australia.

Finding a biocontrol agent for Crassula

Crassula helmsii is an invasive water weed that dominates still or slow-flowing water bodies. It’s spreading throughout the UK and has the potential to out-compete native flora and reduce oxygen levels by forming dense mats. Management of this species can be very challenging, with chemical and mechanical options limited. CABI were commissioned by the UK government to investigate the possibility of controlling the weed using biological control. This includes testing by our scientists to ensure that any potential agent is safe for release.
