Abstract

The present field experiment aimed to estimate yield losses in brinjal due to insect pests. The results revealed that the mean fruit yield from plots treated with alternate sprays of malathion 50 EC at 0.05% and acephate 75 SP at 0.05% was 340.77 q/ha and 343.46 q/ha in 2022 and 2023, respectively. In contrast, the yield from untreated plots was 213.38 q/ha and 210.92 q/ha in the same years. The yield differences between treated and untreated plots were statistically significant, with an increased yield of 127.38 q/ha and 132.54 q/ha in 2022 and 2023, respectively. This represented a yield increase of 59.70% and 62.84%, while the avoidable loss was 37.38% and 38.59% in 2022 and 2023, respectively. The study concluded that yield losses due to brinjal shoot and fruit borer can be effectively mitigated by the protective application of insecticides to the brinjal crop

Conclusion

The study demonstrated a significant increase in fruit yield in treated plots compared to untreated plots in Kharif, 2022 and 2023. The mean fruit yields in treated plots were substantially higher with increases of 127.38 and 132.54 q ha-1, translating to a 59.70% and 62.84% increase over untreated plots in 2022 and 2023, respectively. The pooled data from both years showed a mean yield increase of 129.96 q ha-1, equivalent to a 61.27% increase. Additionally, the percentage of avoidable losses due to insect pests was 37.38% and 38.59% for the two years, with a pooled average of 37.99%. This highlights the effectiveness of pest control measures in significantly boosting brinjal production
