One of the prerequisite for healthy crop and good agriculture production system is healthy seed, health of the seeds are greatly depend on storage condition and proper seed treatment before storage. Seed borne pathogens are responsible for causing various abnormalities in the seed and also result in reducing the yield significantly, if infected seeds are planted in the field. Fungicides have been developed to protect plants against diseases, which cause serious problems such as loss of germination, abnormalities in seedling growth, abnormalities in root and aerial parts and change in biochemical activities. It has been noticed that the storage fungi has effect on the seeds of Cowpea. The deterioration has been reflected in multiple directions. Here the effect of storage fungi has been assessed on root and aerial part of seedling. The storage fungi of the seed not only deviate its physiology and biochemistry but they afflict disease in the seedlings The aim was to test the abnormalities in the root and aerial part of seedling of fungal treated seeds and to study the effect of fungicidal treatment on root and aerial part under different moisture condition. The study was conducted under three moisture level; 6.82% 7.68% and 9.87% and results are compared with control treated seeds. The fungicides used were five commonly used fungicides, they are Thiram, Captan, Bavistin, Difolatan and Dithane M-45. The fungicidal dressing probably destroyed the fungal spores and protected the seeds from deterioration.As regards the pathological symptoms in the root and aerial part of the seedlings raised from the seeds dressed with fungicides, 0.35 Bavistin and Difolatan can be recommended followed by Captan with the caution, the seeds must have less than 9.87% moisture.
