EVALUATION OF CARBOXIN 37.5% + THIRAM 37.5% WP (VITAVAX POWER) AS SEED TREATMENT FUNGICIDE FOR DISEASE CONTROL IN RICE

摘要

Different methodologies of seed treatment of rice with Carboxin 37.5% + Thiram 37.5% were tried. Sprouted seeds treated with the fungicide gave the best control of several diseases, both in nursery and main field. Germination percent and morphologicalcharacters were also better in case of treated seeds. Anong cereals, rice holds the key position in ndia. However, its yield per acre is 3.03t/acre Anon., 2007) which is at a lower rung as compared to that of Australia, Japan and China (FAO, 2000). Biotic stresses like various diseases are one of the reasons for this low yield. Seed borne diseases cause considerable loss, but there is no accurate estimation of this loss. Seed treatment by fungicides is an established and effective management practice and several chemicals like thiram, mercury based compounds, benzimidazole etc. have been targeted for this purpose (Rao and Murlidharan, 1983; Mishra and Vir, 1990).
