Abstract:
A field experiment on seasonal incidence of fall armyworm in maize var. Sugar-75 was carried out at Tetawali block–B, Central Experiment Station, Wakawali, under Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli during Rabi - 2019-20 and 2020-21 to know the status of the pest in Konkan region. The result revealed the, the incidence of fall armyworm population was ranged from 0.03 to 0.45 larvae per plant. The pest incidence was started on 2^nd SMW (8^th Jan to 14^th Jan), however the outbreak was noticed during 8^th SMW (19^th Feb to 25^th Feb) & 9^th SMW (26^th Feb. to 4^th March) i.e. 0.45 larvae per plant while the minimum population was recorded at 13^th SMW (26^th March to 1^st April). The correlation study during Rabi 2019-20 and 2020-21 indicated that, the fall armyworm in terms of larval population showed positively significant correlation with bright sunshine hours and negatively significant correlation with evening relative humidity.
