Abstract

The study was undertaken at Potato Research Station, S.D. Agricultural University, Deesa, Gujarat (India) between 2020-21 and 2022-23 to assess novel insecticidal compounds for their efficacy against aphids in potato crops. The seven different treatments were evaluated against potato aphid. Based on pooled data of three years. The treatment T1, involving two foliar spray of Flupyradifurone 200 SL @0.1% at 14-day interval, exhibited the highest statistically significant reduction (77.91%) in aphid populations at fourteen days after last spray and which was found at par with T4 i.e., Foliar sprays of Pymetrozine 50 WG @ 0.06 % followed by Flupyradifurone 200 SL @ 0.1 % (14 days after last spray. Furthermore, T1 demonstrated superior tuber yield (48.81 t/ha) and a higher Benefit-Cost (BC) ratio of 2.10 compared to the untreated control treatment

Conclusion

Based on the findings of this investigation, it is deduced that two foliar spray of Flupyradifurone 200 SL @ 0.1% with a 14-day interval effectively controls potato aphids while also yielding superior economic returns. This treatment regimen not only mitigates aphid infestations efficiently but also enhances profitability in potato cultivation
