Sariah Meon, . Infection of chilli by Cercospora capsici. pp. 321-325. ISSN 0126-6128
Abstract
Cercospora capsici was shown to be consistently associated with leaf spot of chilli reducing appreciably the photosynthetic activity of infected plants leading to losses in yield. Incipient symptoms consisted of small necrotic lesions on the surface of the leaves which later coalesced giving an irregular and blighted appearance with the production of abundant conidia. The pathogen sporulated abundantly at 20-30 deg C but poorly at 10 deg C. At 40 deg C no sporulation occurred. Sporulation on lesions was greatest near moisture saturation but declined with decreasing water potential to -6 MPa. The best temperature for germination was in the range of 20-30 deg C and declined with decreasing water potential. Pathogenicity tests and studies on the mode of infection of C. capsici on chilli leaves revealed that it was a primary invader.
