Nano-Particle Derived from Chaetomium cuprem cc3003 against Anthracnose of Coffee var. Arabic

Abstract

Colletotrichum gloeosporioides is proved to be a pathogenic isolate causing anthracnose disease on coffee var. Arabica in Lao PDR. Chaetomium cupreum CC3003 inhibits sporulation of C. gloeosporiodes by 42.60% in 30 days. The tested nano CCH, nano CCE and nano CCM derived from C. cupreum CC3003 significantly inhibits C. gloeosporioides that cause coffee anthracnose at low concentrations of about 3–15 ppm. The tested nano-particles applied to inoculated coffee seedlings significantly reduce coffee anthracnose. Research and development on nano-particles extracted from fungi are necessary to discover new strategies to control plant disease.
