Abstract: (1) For systematic studies of the Fungal ecology of Golaghat Sub-division of the district Jorhat, Assam; the whole sub-division was divided into eighteen sectors. It comprises 3540.7 sq. kms. of land. The sectors are - (1) Golaghat, (2) Kamarbandha, (3) Athgaon, (4) Ghiladhari, (5) Merapani, (6) Dakhinhengra, (7) Missamara, (8) Dergaon, (9) Gurju-Gonia, (10) Kakodunga, (11) Kathalguri, (12) Rongamati, (13) Kamargaon, (14) Bokakhat, (15) Kaziranga, (16) Marangi, (17) Borpathar, (18) Sarupathar. (2) A map indicating the whole area and the sectors has been attached for ready reference. (3) Actual study started in the month of January/1984 by visiting all the sectors. The visits were made at different areas of cultivated crops, season-wise and collected the disease materials with records of rainfall, temperature, humidity and soil types. This has been continued for three years consequtively in 1984, 1985 and 1986 and recorded the necessary datas for investigation. (4) There were altogether 14 types of cultivations namely viz-Cereals, Pulses, Cole crops, Root crops, Bulb crops, Fruit vegetables, Tuber crops, Corms, Leafy vegetables, Fruits, Spices, Plantation crop, Cash crop and Fats and Oil crop. So far, different crops are concerned, it was found to be about 14 types; among which main types are Rice, Pulses, Cole crops, Fruit vegetables, Corms, Leafy vegetables, Fruit crops, Betelnut, Betelvine, Bamboo, Tea, Sugarcane and Mustard. (5) The whole sub-division is more or less plain, altitudes varies from 65 to 118 metre. The main rivers of the sub-division are Dhansiri, and Dayang, But with limited occurrence of flood. Rainfall generally varies from 5.5mm - 79.5 mm. during winter season and 52.8 mm - 394.2 mm. during summer season, with humidity in between 60%-90%. The temperature is also more or less similar in whole of the sub-division varying from 22.30 - 36.60c in summer and 3.20c-21.90c in winter. (6) Parasitic fungal diseases were recorded on different cultivated crops, sector-wise. There were altogether 124 sp....
