The peanut wilt caused by Sclerotium rolfsii Sacc was widely distributed over the peanut growing regions throughout this Island. Approximately 9-15% of the plant wilted in the field during July to September yearly. In order to improve the seedling emergance an effort was made, to find some dependable seed protectants which could be recommended for use with this crop. This paper presents the preliminary results on the effectiveness of severals seed protectants on the seedling emergance of peanut in compost, infested with S. rolfsii, in Taipei, Taiwan,
From the results of seed germination obtanied in greenhouse and field trials it was concluded that majority of fungicides used in this experiment were proved to be of some value and may be expected to improve the stands after treatment. Of the materials used, Spergon at 0.8 per cent and Agrosan GN at 0.8 per cent dosages by weight of seed showed the most promice while Arasan SF at 0.4 per cent the next.
The effect of Phygon. XL, Femide and Phygon at all dosages were not so significant in the greenhouse trial as compared with the field trial but in the condition of the former the percentage of seed germination tends to increase toward the higher dosage.
New Improved Ceresan retarded seed germination when its dosage is over 0.2 per cent but the percentage of seed germination tends to increase as its dosage decreased. Then in conclusion New Improved Ceresan would have its fungicidal value for this crop if lower dosage was recommended.
