The Fall Army worm (FAW), or spodoptera frugiperda, is the latest threat that the agricultural sector is facing. FAW, which wreaked wide Spread Distruction in Africa, entered Karnataka last year and spread very rapidly to other States. Though it predominantly infects maize, Fall Armyworm has the potential to spread to many other crops. The fact that it spread to 50 countries in two continents in just two years reflects the speed with which it spreads, causing large-scale damage to crops. Dos and don'ts set up five pheromone traps in the infested area and also in areas that are likely to be affected by Fall Armyworm. They should be there both in crop season and off season too Deep ploughing is recommended before sowing. This will expose FAW pupae to predators.  Timely sowing is advised.  Avoid staggered sowings.  Inter-cropping of maize with suitable pulse crops that are vogue in a particular region Growing ornamental flowering plants as an inter-crop will help in build-up of natural enemies. Balanced use of fertilisers and cultivation of maize hybrids with tight husk cover will reduce ear damage by FAW,” Hand picking and destruction of egg masses and neonate larvae in mass by crushing or immersing in kerosine water would help Application of dry sand in to the whorl of affected maize plants immediately after noticing the FAW incidence will also help
