Abstract

Coconut is an important plantation crop in India. Many diseases severely impact coconut trees in the current climate change scenario, declining the vigor and yield of palms and deteriorating the quality of nuts on the trees. Basal stem rot caused by Ganoderma spp. is one of the most destructive diseases of coconut. Ganoderma can endure an extended period in the soil as a soil-borne pathogen. Chlamydospores are formed under unfavourable conditions, helping the pathogen's survival and spread of the disease. Rain and irrigation water also contribute to the spread from one field to another. This study assessed coconut consortia's efficiency in combating the basal stem rot disease at the field level. The experimental trial was conducted at Tittuvillai village of Thovalai panchayat, Kanyakumari district, from 2021–2022 to 2023–2024 for three consecutive years with four treatments and seven replications. The palms exhibiting the typical symptom were selected, and the experiment was started in 2021. A total of 28 palms displaying basal stem rot symptoms were randomly selected for the experiment. Four treatments were imposed, and the details of treatments include T1: Drenching of Coconut consortia (TNAU Cococon) @ 2 liters/palm along with application of mycorrhizae @ 100 g/palm at quarterly interval, T2: Drenching of Coconut consortia (TNAU Cococon) @ 2 litres/palm and root feeding with hexaconazole (0.2%) at quarterly interval, T3: Drenching of Bordeaux mixture 1% and T4: Control (Untreated). Among the four treatments, soil drenching of coconut consortia (TNAU Cococon) @ 2 liters/palm followed by root feeding with hexaconazole (0.2%) at quarterly intervals effectively reduced the disease index from 21.74 to 15.96 and enhanced nut yield from 67.14 to 90.00 nuts per palm per year in three years under field conditions.
