The significance of extracts of Garlic, Allamanda and Neem were tested to pprevent seed-borne fungi of Okra seeds collected from the farmers of Monirampur Upazilla of Jessore district. Sprouting test and presence of seed-transmitted fungi were investigated by blotter method in the Pathology Center of seed (SPC) and M.S. laboratory at Bangladesh Agriculture University (BAU). Plant extracts are very vital for seed treatment because they can purification fungal pathogens, bacteria, and other organisms that affect seeds. Plant extracts are also stimulants that can improve seed germination and plant growth. The largest germination status was collected from Ufsi (90%), while the lowest (50%) was in Muktessari. There are Six types fungal genera were identified. The type of genera of fungi were Fusarium oxysporum (5.33%), Aspergillus flavus (4.3%), Aspergillus niger (5.30%), Colletotrichum dematium (4.80%), Rhizopus stolonifer (3.66%) and Penicillium sp. (3.17%). The nutrient Agar plate technique resulted in one bacterial isolate Pseudomonas sp from okra seeds. Seed Germination status and fungal infection varied from spices to spices. In experimented seeds among all the plant extracts viz. garlic, neem, and allamanda germination differ from 60-90% and infections were recorded from 0.57-5.6%. Garlic extracts @ 1:1 showed the best performance in increasing seed germination (95.5%) next to Neem (60%) and reduction of fungal flora (53.25%). The Vigour index of Okra seeds was increased by 27.91% over untreated seeds by the treatment of Garlic extracts @ 1:1. Garlic extract@1:1 seemed to be adoptable at the farmer’s level as an organic management practice.
