Abstract : A study was conducted to determine the host range of anthracnose (C. gloeosporioides [Glomerella cingulata]) in cashew (Anacardium occidentale) nurseries where 15 plant species including weeds acted as hosts and spread the pathogens. Among the 5 plant species tested, cashew showed the highest susceptiblity to anthracnose disease followed by Mangifera indica, Citrus sinensis, Annona squamosa and Punica granatum. All the 10 weeds (Aristolochia bracteata, Achyranthes aspera, Argemone mexicana, Corchorus trilocularis, Cleome viscosa, Datura stramonium, Parthenium hysterophorus, Leucas aspera, Tribulus terrestris and Tridax procumbens) were susceptible to C. gloeosporioides, recording a range of 13.24-70.00 percent disease index.
