Abstract: Growing incidence of red ants causing damage to tubers has been a major problem among potato farmers in Doti. A field experiment was carried out at farmer’s field in Budar, Jorayal Rural Municipality-2, Doti during March-June, 2023 to study the performance of locally available botanical pesticides on red ant infestation to potato tubers and compare it with chemical control. Five treatments namely Eupatorium (Banmara) (T1), Jholmol (T2), Agave americana (Ketuke) (T3), chlorpyriphos 50% EC + cypermethrin 5% EC (T4), control (T5) were arranged in a randomized complete block design and replicated four times. A significantly higher marketable yield (t ha-1) was observed in all treatments except control (T5) (7.42±1.46 tonnes); the highest marketable weight was observed in chlorpyriphos 50% EC + cypermethrin 5% EC (T4) (16.07±1.46 tonnes) being at par with Jholmol (T2) (15.57±1.46 tonnes), Eupatorium (Banmara) (T1) (15.37±1.46 tonnes) and Agave americana (Ketuke) (T3) (13.13±1.46 tonnes). Results also exhibited that the application of Jholmol (T2) (4.75%), Eupatorium (Banmara) (T1) (9.64%), Agave americana (Ketuke) (T3) (15.70%) were statistically at par with chlorpyriphos 50% EC + cypermethrin 5% EC (T4) (0%) in terms of loss percentage of tubers due to red ants whereas control (T5) had the highest loss percentage of 46.33%. However, B: C ratio was the highest from Eupatorium (Banmara) (T1) and the lowest from chlorpyriphos 50%EC + cypermethrin 5% EC (T4). This study suggests that there are statistically significant botanical alternatives (especially Eupatorium (Banmara) to chemical pesticides and proposes further study into the performance of botanicals.
