Effcct of Fungicidal Seed Treatment and Commercially Available Seed Dressers on Safflower Seed Germination and Seedling Vigour

摘要

The seeds treated with Thiram + Carbendazim showed lowest percentage of mycoflora and recorded superiority over rest of the treatments in all the test varieties followed by Thiram. In case of individual seed flora systemic fungicides yielded better result against Alternaria carthami and non-systemic fungicides against Aspergillus flauus. While in total seed flora PBNS 12 cuitivar showed overall best response to all fungicidal treatments. Thiram + Carbendazim treatment over total seed mycoflora was recorded to the tune of 12.8 (Manjira), 10.9 (Sharda), 8.5 (PBNS 12) and 13.9 (Nira) per cent in blotter paper method, while 13.0 (Manjira), 11.0 (Sharda), 9.9 (PBNS 12) and 14.9 (Nira) per cent in rolled towel method. All the fungicides improved the germination percentage and restricted pre and post emergence mortality. Thiram + Carbendazim and Thiram treatments gave maximum germination percentage with increased vigour index and reduced- seed mycoflora percentage in all varieties and methods.
