ABSTRACT
Potato (Solanum tuberosum L.) is the fourth major food crop of the world and it is gaining status of cash crop in Gilgit Baltistan. White grub is most destructive insect pest damaging potato tubers and causes economic loss of Gilgit-Baltistan. The study was conducted with an aim to develop eco-friendly management of white grub. Fermented extracts of four herbs Sophora alopecuroides, Artemisia sieversiana, Peganum harmalla and Tagetes minuta were evaluated against white grub under field conditions for two consecutive growing seasons during 2018 and 2019. The minimum per cent infestation, number of white grubs per plot, yield loss and maximum tuber yield was recorded in plots treated with S. alopecuroides fermented extract and Refree. The fermented extract of S. alopecuroides significantly reduced percent infestation, number of white grub per plot and yield losses as compared to the control plot, however efficacy of the fermented extract of A. sieversiana, P. harmala and T. minuta was significantly low as compared to Refree. Our current field study indicated that the fermented extract of S. alopecuroides has potential to develop eco-friendly approach for management of white grub.
