Mujibar4200254The effectiveness of solar heat in controlling seed borne fungal infections of wheat was tested by drying of seeds on concrete floor, brown paper and mixing with sand (50:50) for 0, 4, 8 and 12 hours. It was observed that the seeds dried with sand mixture always yielded lowest number of seed borne infections of all the fungi followed by concrete floor and brown paper. Reduction rate of fungi achieved in all the treatments differed significantly from that of control. Twelve hours was the best period in inhibiting the seed borne infections. However, in some cases both 12 and 8 hours treatments behaved equally. Reduction of total seed borne infection and increase in seed vigour positively correlated with the increase in drying period. Therefore, to minimize the seed borne infections, it would be advisable to use seed dried with sand mixture for 12 hours under direct solar heat.]]>Agarwal, R.L.,19962nd Edn.,pp: 583-590pp: 583-590Bedi, K.S.,195710138141Fakir, G.A., M.A. Sardar, G.A.
