Integrated Management of American Fall Armyworm (Spodoptera Frugiperda) on Maize Crops
Fall armyworms majorly impacts the maize crop in the United States and its outbreak has been observed in Southern India since June last year. This pest caused serious damage to Kharif, Rabi and summer seasons, as well as tea and maize crops during the last year. Maize cultivation is currently postponed due to delayed rainfall throughout the country. In the coming season, there is a strong possibility of significant crop losses in all maize-producing states, including Maharashtra. It is time to collectively incorporate all-inclusive integrated pest control measures into the management of this pest.
Integrated management: Napier grass trap has to be planted as a side crop for maize. Immediately after sowing the maize crop, 10 T perches per acre should be established in per one acre of the field. Eggs that appear in the early phases on the corn leaf and larvae should be gathered and demolished. Before sowing for pest studies and for further installation of 15 such traps, five pheromone traps should be mounted. Spray 5 per cent neem extract or 1500 ppm Azadirectin 50 ml per 10 litres of water for the control of larvae in the original phases. Nomuria Relay 50 gm or Metarhizium Anisopliae 50 gm per 10 litres of water should be sprayed with biopesticide. Spraying Bacillus thuringiensis (Bt) is also helpful for the control of fall armyworm pest. While spraying pesticides, it is essential to be cautious and follow the proposed procedure. Emamectin benzoate 5% SG 4 gm or Thiamethoxam 12.6% + Lambda Cyhalothrin 9.5 ZC @5 ml or Spinetoram 11.7 SC @4ml or Chlorantraniliprole 18.5 SC @4ml should be sprayed with 10 litres of water.
