Synthetic pesticides have made an impact on aphid control but limitations due to the development of resistance and negative impact on humans and the environment, focus has shifted to alternative strategies. We explored the effectiveness of indigenous plant extracts of  Artemisia absinthium  and  Prunus armeniaca  against  B. brassicae  and  H. pruni  while preserving its natural enemies. Four replicates of the extracts were studied under laboratory conditions. Ethanolic extract of  Artemisia absinthium  (EEAA) shows 75.64% and 60.25% mortality while ethanolic extract of  Prunus  apricot kernel (EEPAK) shows 66.66% and 48.71% mortality of  H. pruni  and  B. brassicae  respectively ( p  &lt; 0.01). Similarly, aqueous extracts of  Artemisia absinthium  (AEAA) and  Prunus  apricot kernel (AEPAK) also seem to be useful with 62.5% and 58.78% mortality in  H. pruni,  respectively. Of the different ethanolic extracts, 5% of AA was found most effective against aphids with a population reduction of 75.64% while 1% of aqueous extract of the PAK showed the least (7.69%) aphid mortality. Due to their availability, affordability, and eco-friendly, small-scale farmers can use them as a replacement for chemical pesticides. Thus, we suggest the use of  Prunus  apricot kernel (PAK) and  Artemisia absinthium  (AA) for the management of aphids in and around Ladakh.
