Control Strategy: Integrated Pest Management

Control Measures: Integrated Pest Management

As fall armyworm (FAW) possess the ability to cause significant crop yield losses and a threat to food security; hence the management and control strategies need to be practice with utmost priority and caution. Furthermore, as the trade and transportation proliferate around the globe, the infested region continues to serve as a hub of dispersal of FAW pest around the globe. If the pest reaches the environmentally and geographically suitable conditions, the species can survive year-round with continuous expansion and pose a severe threat to global food security. On the contrary, being an invasive species with high reproductive capacity, the pest still presents certain areas of weakness such as the absence of diapause and vulnerability to natural enemies which could be utilized for planning management strategies. Meanwhile, the unaffected area needs to proceed forward with caution while practicing quarantine strategies wherever required. Also, the concerned stakeholders from affected and unaffected areas should come forward to build knowledge bases which could assist national and regional pest risk assessments and appropriate control measures of this devastating pest as enumerated below;

  • Pheromonal Control
    • Survey & Monitoring
    • Mass Trapping
    • Mating Disruption
  • Biological Control
  • Biotechnological Control
  • Chemical Control
    • Seed Treatment
    • Foliar/Whorl Applications

However, based in the global experiences, the Integrated Pest Management, IPM triangle is an outline of best practices to be followed by farmers to avoid any unforeseen events due to FAW infestation. Following illustration demonstrates the integrated pest management (IPM) as a holistic solution to fall armyworm.

Adherence to responsible agricultural practices, besides integrated pest management plans, can help the farmers avoid or detect and eradicate early stage FAW infestations.

  • Seed Treatment: Always use maize seeds treated as per approval of Central Insecticides Board and Registration Committee (CIBRC), Ministry of Agriculture & Farmers’ Welfare, Government of India
  • Village-wide Approach: Timely & Synchronized sowing of quality seeds
  • Good Agricultural Practices (GAP: Always follow good agri practices by State Agricultural Universities (SAUs) / Indian Council of Agricultural Research (ICAR)/States Agriculture Department
  • Install Pheromone Trap: Install 4-5 pheromone trap/acre at the time of germination, regularly monitor FAW adult moths & scout for pest incidence & plant damage at early stage of crop
  • Action Window 1: Destroy egg mass/neonates larvae and apply foliar spray 5% NSKE / Azadirachtin1500ppm @ 5 ml/litre of water & other recommended biologicals. In case of heavy significant, apply Chlorantraniliprole 18.5% SC (CoragenTM/CoverTM/VesticoreTM etc) @ 0.4 ml/litre of water or Thiamethoxam 12.6% + lambda cyhalothrin 9.5% @ 0.5 ml/litre of water
  • Action Window 2: During mid-whorl to late whorl stage, scout for larvae and plant damage & incase of need, go for whorl spray either Chlorantraniliprole 18.5% SC (CoragenTM/CoverTM/VesticoreTM etc) @ 0.4 ml/litre of water or Thiamethoxam 12.6% + lambda cyhalothrin 9.5% @ 0.5 ml/litre of water
  • Action Window 3: Tasseling and post tasseling stage, insecticide application is not cost effective & therefore farmers are advised to install pheromone for mass trapping and bird perches
