Info on biology and ecology of Fall Armyworm and experiences in other countries shared
Says range of non-pesticide options also given
Eradication of Sena unlikely, farmers will have to learn to manage it as any other pest

The Food and Agriculture Organisation (FAO) yesterday said it had shared information with the Agriculture Ministry on effective methods to combat the Fall Armyworm, including non-toxic options, and stands ready to provide technical assistance in the future.

The Fall Armyworm (FAW) or Spodoptera frugiperda has been reported in all major maize growing areas in Sri Lanka and is also affecting sugarcane cultivation. There is a growing concern that it may affect other crops, including rice, FAO said in a statement.

In the absence of natural control or good management, the FAW can cause significant damage to crops and affect the livelihoods of farmers. Once established in a new area, FAW cannot be practically eradicated. It becomes one more pest that farmers need to learn about and manage, it said.

“Raising awareness about the FAW and understanding lessons learned from other parts of the world, including available management options are essential first steps in responding adequately to the situation in Sri Lanka. In this regard, the Food and Agriculture Organisation of the United Nations (FAO) has shared background information with the Ministry of Agriculture and the Department of Agriculture on the biology and ecology of the FAW, on how to scout the pest, and on management strategies. The information includes a range of options available that don’t use hazardous pesticides, minimise the use of chemical pesticides, and educate policy makers and farmers about agro-ecological approaches used by small-holder farmers in Latin America and being tested by small-holders in Africa and India as well,” it said.

Field guides and Guidance Notes about FAW Integrated Pest Management (IPM) strategies developed by responding to the outbreak in Africa, particularly by implementing Farmer Field Schools, have been disseminated to the Ministry of Agriculture and the Department of Agriculture in Sri Lanka. Tools such as the Fall Armyworm Monitoring and Early Warning System (FAMEWS) mobile app developed by FAO to collect information on FAW population levels by field scouting and/or use of pheromone traps have been shared. FAMEWS supports all stages of FAW management: to identify the pest, monitor the level of infestation to map its spread to make decisions, as well as to learn about the important natural enemies and the measures that are most effective in managing it.

FAO remains committed to supporting the concerned national authorities to manage the pest and to protect the Sri Lankan farmer community’s livelihoods. The Organization will continue to monitor the situation in Sri Lanka and provide any technical assistance/expertise requested by the Government.

Native to the Americas, FAW was first detected in Central and Western Africa in early 2016 and quickly spread across virtually all of Sub-Saharan Africa. In July 2018, it was confirmed in India in Karnataka state and since then it has been found in seven other States including in Tamil Nadu. FAW was also detected in Yemen in 2018 and has now reached Sri Lanka.
