1st day workshop plant disease

Two day training sessions on Plant Disease Diagnosis


The two day training on Plant Disease Diagnosis was conducted in the Department of Food Production, Faculty of Food and Agriculture, The University of the West Indies, St. Augustine from 13 to 14th July, 2016 to Agricultural Extension Officers of Trinidad and Tobago. The training was organized 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 twenty three agricultural Extension Officers of Trinidad and Tobago representing seven counties [St. George County, St. David County, St. Andrew County, 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 program, 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. They had hands on experience in identification of damping off in vegetable nurseries, Phytophthora collar rot and anthracnose in hot pepper, gummy stem blight in pumpkin and christophene, fungal and bacterial wilts in tomato, downy mildew and powdery mildew in cucurbits and okra, black mold in okra, cercospora leaf spot in cucurbits, rust and pod rot in bodi, bacterial leaf spot and leaf speck in tomato, hot pepper and lettuce.  Further, the training has exposed the officers to identify the pathogens based on the existence of signs, microscopic observations, morphological characters and molecular techniques such as ELISA (Enzyme Linked Immunosorbent Assay) and PCR (Polymerase Chain Reaction).

The participants were trained to isolate and observe the pathogenic fungi and bacteria from the infected cucumber and tomato plants. Senator Avinash Singh, Parliamentary Secretary, Ministry of Agriculture, Land & Fisheries has attended the closing ceremony of the two day training programme on 14th July, 2016 to deliver the special address and present participation certificates to 23 agricultural extension officers who successfully completed a two day training program. Senator Avinash Singh has emphasized the need for plant disease diagnosis by quoting the Plantwise program’s data on the current loss in crop production due to plant pests and diseases. He also said that for every 1% reduction in crop pests and diseases, plantwise program has estimated that an extra 25 million people could be fed. Thus to ensure food security of the region, he called the need for empowering the knowledge of agricultural extension officers in the field of pest and disease control by training programs so as to effectively serve the farming community. Senator Singh himself a farmer, he shared his own experience with serious occurrence of pest and disease problems in crops with the participants. Dr. Reynold Stone, Head, Department of Food Production and Dr. Wayne Ganpat, Head, Department of Agricultural Economics and Extension, UWI were present and congratulated the participants for successful completion of the training. The training was facilitated by Dr. Duraisamy Saravanakumar, Senior Lecturer and AIMS Project Leader, UWI-RDI Fund, Department of Food Production, Faculty of Food and Agriculture, UWI, St Augustine campus.
