Anthracnose development was not influenced by different plant population. Yield loss of marketable fruits was 99–5%. Carbendazim and benomyl applications had decreased disease intensity, increased yield and decreased infection rates. Carbendazim, benomyl and captafol had reduced the basic infection rate R values to 1:18, 1:10 and 1:4, respectively. Correlations between the disease indices and marketable and total fruits were negative, while with the diseased fruit numbers were positive. Bottlegourd anthracnose epidemic progressed as a polycyclic disease.
