We’ve selected a few of the latest new geographic, host and species records for plant pests and diseases from CAB Abstracts. Records this fortnight include the first report of Rhizoctonia oryzae causing crown and root rot on wheat in Chile, a survey of nematodes associated with fruit trees in the state of Amapá, Brazil and the first report of Ramulispora sorghi, a new pathogen of sorghum in NE Argentina.

A two day training on Plant Disease Diagnosis was conducted in the Department of Food, Faculty of Food and Agriculture, The University of the West Indies, St Augustine from July 13 to 14 to agricultural extension officers of Trinidad and Tobago.

The training was organised under the auspices of The UWI-RDI (Research Development Impact) funded project on ‘Promoting Agriculturally Important Microorganisms to Address the Challenges in Food Safety and Food Security in the Caribbean”. The training was attended by 23 agricultural extension officers of Trinidad and Tobago representing seven counties [St George, St David, St Andrew, County Caroni, Nariva/Mayaro, St Patrick West, County Victoria] of North Regional Administration and South Regional Administration, Research Division Central Experiment Station, Extension Training and Information Services Division and Agricultural Division of Tobago. During the training programme, the agricultural extension officers were trained to diagnose the various vegetable diseases caused by fungi, bacteria, viruses based on the symptom expressed in roots, stems, vascular tissues, leaves and fruits.

Known as the poor people’s crop, cassava (Manihot esculenta Crantz) is one of the most important subsistence crops in Africa, particularly in sub-Saharan Africa and West Africa being consumed fresh, cooked or processed. It is estimated that cassava contributes to nearly 40% of the total daily calories consumed by poor smallholders in marginal and sub-marginal areas. The significant contribution to daily calories is due to its efficient production and storage of starch on the roots.

Plantwise Vietnam training on data validation, processing and analysis

Reblogged from Vietnam Academy of Agricultural Sciences news


During 3-day training workshop, participants learnt how to validate Plantwise diagnoses and recommendations and how to analyze data from Vietnam stored on the Plantwise Knowledge bank. This activity is useful and necessary for the staff working in plant protection because they can examine and evaluate skills and qualifications of Plant doctors and also can have an overall vision and panorama picture about pest and diseases of each plant in each region of the project.  Thus, the need for training of Plant doctors could be identified with the aim to enhance their skills and knowledge, to diagnose more accurately pests, and to improve the quality of advice helping farmers prevent effectively pests and diseases, while ensuring safety for people and environment.

“Pest-smart” to climate-smart in Southeast Asia

Climate-smart agriculture calls for pest management that controls farm pests and diseases in a way that does not negatively affect ecosystem services and human health.

Climate change affects not only farming practices in that extreme events may flatten trees and crops. It also affects the distributions and life cycles of animals and insects such as pests, disease-causing organisms and crop-pollinating insects and animals. Farmers in Vietnam speculate that the increase in temperatures brought about by climate change might be favouring certain pests.

To further understand the behavior, control and management of pests and diseases in the light of climate change, the Centre for Agriculture and Biosciences International (CABI) Southeast Asia is conducting “Pest Smart”, a two-year initiative under the CGIAR Research Program on Climate Change, Agriculture and Food Security Southeast Asia (CCAFS SEA) Climate-Smart Villages (CSVs) project.
