EFFICACY OF SOME ESSENTIAL OILS AGAINST PHOMOPSIS AZADIRACHTAE - THE INCITANT OF DIE-BACK OF NEEM

Abstract

ABSTRACT Phomopsis azadirachtae causes die-back of neem. This disease has become a major devastating disease of neem in India resulting in 100% loss of fruits. To develop an eco-friendly biocontrol strategy for the control of this pathogen five essential oils viz., eucalyptus oil, fennel oil, pepper oil, coriander oil, nutmeg oil, and two oleoresins namely, capsicum oleoresin and turmeric oleoresin were tested in vitro against this fungus. Nutmeg oil, coriander oil and turmeric oleoresin were very effective against P. azadirachtae and can be used to manage this fungus.
