Two Plant Health Rallies have recently been held in Grenada to raise awareness of the West Indian Fruit fly and promote the control of this pest using fruit fly bait stations. The rallies, which were organised in collaboration with the Ministry of Agriculture, Lands, Forestry, Fisheries and the Environment, were aimed at local farmers with the first attracting 25 attendees and the second around 12. The farmers were given practical advice on how to make and use bait stations which they were able to take away with them afterwards. Thaddeus Peters (MoA) presented at one of the rallies explaining what damage the West Indian fruit fly causes and how the MoA and farmers can both play a part in controlling the pest.  Read more of this post

Plantwise in Pakistan and its opportunities to share knowledge

In June 2014, Dr Aamir H Malik, CABI Country Coordinator for Pakistan, Cambria Finegold, Head of Project Development for the Plantwise Knowledge Bank and Julien Lamontagne-Godwin, Plantwise scientific officer, organised a workshop in Islamabad that united major stakeholders in the Pakistani plant health system. These included the departments of Extension and Adaptive Research, Pest Warning and Quality Control of Pesticides, Agricultural Information, the National Agricultural Research Centre, the Punjab Seed Corporation and the Horticultural Development and Export Company.

The objective was to demonstrate the power and possible use of the data being generated by the rising number of plant clinics in the country. The participants felt that it is crucial that the data, owned by the Directorate General of Extension and Adaptive Research, is shared to a maximum amount of actors in the plant health system.  This will enable them to work more efficiently in the agricultural domain, depending on their mandates: develop updated and topical research strategies, conduct more targeted extension campaigns, understand the health of various crops in a region and develop better seeds or resistant varieties. Indeed, this is one of the core objectives of Plantwise.

Overall, the workshop was an unqualified success, as many partners are now keen to be linked to the data sharing platform that is the Plantwise Knowledge Bank, and receive topical and interesting data from the Directorate General of Extension and Adaptive Research plant clinics.
