Incidence and severity of leaf blight caused by Fusarium pallidoroseum on varied age of Castor (Ricinus communis) inoculated using different methods

Abstract

Castor seeds were planted at three different times of seven days interval (11, 18 and 25 DAS) so as to have varying ages at inoculation date. The plants were inoculated at the same time using three methods (spray, smear and soil inoculation). Plants at 11 and 18 DAS had higher incidence and severity and were not significantly different (P=0.05), while plants at 25 DAS had the least disease and was not significantly different with the control (P=0.05).
