Study was carried out to evaluate the repellency property of various biomedicinal oils and two acaricides against two spotted spider mite on castor. The treatments neem oil, pungam oil, pinnai oil, mahua oil, mustard oil, dicofol and fenazaquin alongwith untreated check were tested for their efficacy against two spider mite. The maximum repellency was recorded in case of fenazaquin followed by dicofol and neem oil. The pungamoil and pinnai oil shows on par results, whereas the mahua oil recorded a moderate repellency against mite. The least repellency was recorded in mustard oil against two spotted spider mite after 48 hrs of release. Plant biomedicinal oils are ecofriendly, hence leads to a safer environment to the people.
