A severe leaf spot disease on the weed Clerodendron (Clerodendron infortunatum) caused by Colletotrichum gloeosporioides, newly reported in clove gardens of Kerala, India, may serve as a source of inoculum for the leaf spot, twig blight, and flower shedding disease of clove (Eugenia caryophyllata). The causal organism survives well under adverse conditions on infected leaves of Clerodendron.
