Ufra disease has broken out in the Ayeyarwady region of Myanmar. The partial emergence and distorted panicles are due to nematode infection.

Ufra disease has broken out in the Ayeyarwady region of Myanmar. The partial emergence and distorted panicles are due to nematode infection.

Here’s a taste of some of the latest stories about plant health, including the insect-resistant maize that could increase yields and decrease pesticide use in Mexico, nematodes that are threatening rice in the Ayeyarwady Region of Myanmar and a study into how salt-loving plants could contribute to sustainable global food production.

Mexico eradicates Mediterranean fruit fly

Mexico’s Secretary of Agriculture, Livestock, Rural Development, Fishing and Food (SAGARPA) has declared the country free of the Mediterranean fruit fly, Ceratitis capitata, in a development that is expected to ease trade restrictions and boost the produce industry.

The declaration will positively impact on 1.8 million hectares of growing land for some key agricultural crops – including tomatoes, mangoes and avocados – with an annual production of 17.6 million metric tons (MT). The total value of the affected produce is estimated to be around 86 billion pesos (US$6.4 billion).

SAGARPA said the fruit fly’s eradication was a result of phytosanitary measures that had been in place for 35 years.

Fruit flies are a menacing pest across the world, causing damage to fruits and other agricultural crops with large financial consequences for international trade when export bans are imposed. For example, Pakistani mango imports were at risk of being banned by the EU earlier this year due to fruit fly infestations (http://www.newspakistan.pk/2014/06/23/eu-ban-import-pakistani-mangoes-due-infestation/), and in May this year the EU controversially banned all imports of Indian mangoes due to the discovery of tropical pests in the imported produce (http://www.bbc.co.uk/news/business-27238239).

Pesticides-L mailing list: creating a global conversation on pesticides issues

Written by Melanie Bateman, Integrated Crop Management Adviser, CABI Switzerland

plant clinicAs has been mentioned before in this blog, there are a staggering number of chemicals in the world – estimates go as high as 2 million different preparations for sale. This is a lot for regulators in any given country to assess and monitor for safety concerns, especially given the nature of many of the problems associated with pesticides. While symptoms of acute pesticide poisoning become apparent relatively rapidly after exposure, chronic effects such as cancer can be caused by repeated, low level exposure over extended periods of time. For these chronic problems, it is much more difficult to uncover the connections between the chemical and the disease.

International agreements such as the Rotterdam and Stockholm Conventions provide formal channels for information sharing on these issues between countries.

At a recent workshop on pest management and pesticide risk reduction, Mr David Kamangira, Senior Deputy Director in Zambia’s Department of Agricultural Research Services, offered up a suggestion for a grassroots approach for sharing information and staying informed about pesticides. He shared his experience with the “Pesticides-L” mailing list, an online forum for discussions regarding pesticides management issues. Moderated by Dr Andrea Rother of the School of Public Health and Family Medicine of the University of Cape Town, Pesticides-L is open to anyone with an interest in issues related to pesticides. Posts to the list cover topics ranging from research results on human health and environmental effects to policy debates to meeting announcements. The Pesticide-L mailing list is a rich information source and a valuable tool for linking together a global community of stakeholders such as researchers, NGO’s, chemical companies, policy makers, affected individuals, unions, farmers, community groups and government representatives. To subscribe to this list, email ‘pesticides-l-owner@lists.uct.ac.za’.
