Abstract

The investigation of “Evaluation of different insecticides against Spodoptera frugiperda (J.E. Smith) in maize”. The field experiment was conducted on the field of progressive farmer Shree. Baburao Mhaske Domegoan, Taluka Ambad, Dist. Jalna under the guidance of research guide, college of agriculture Badnapur during kharif 2021. The work was carried out in Randomized Block Design with three replications and Seven treatments. The net plot size and gross plot size was 3.0 m × 2.2 m and 4.2 m × 3 m respectively with maize crop variety Fourtuner. The studies revealed that, after three application of insecticides for the management of Spodoptera frugiperda, Emamectin benzoate 5SG (T1) was found to be effective against the fall armyworm and egg masses of fall armyworm population, followed by Chlorantraniliprole 18.5 SC (T2), Spinetoram 11.7 % SC (T3), Flubendiamide 49.35 SC (T3), Indoxacarb 15.8 EC (T4) and Chlorfluazuron 5.4 EC (T6). The maximum population of fall armyworm and egg masses of fall armyworm was observed in untreated control as compare to all other treatments. To convince the farmer for layout experiment in already planted crop and to keep watch on the activities of pest and it's response to different treatments were the challenges. The entire research programme monitored and guided by research guide besides all the inputs were provided by college of agriculture Badnapur and losses occurred in the plant population during layout and losses in the yield caused by untreated control were beared by farmer.

Conclusion

The study indicate that among the all treatments Emamectine benzoate 5 SG (T1) @ 4 gm/10 L was found best with the lowest population of spodoptera frugiperda larvae and their egg masses. Result revealed that next better treatment was Chlorantraniliprole 18.5 SC (T2) @ 3 ml/10 were found effective against fall armyworm of Maize.
