Species of Fusarium are responsible for a variety of seedling diseases including seed rots, pre and post-emergence damping-off, wilts, root rot, and late season damping-off. Several disease management strategies are available e.g. cultural, biological control, resistant cultivars, crop rotation and chemical control. Resistant cultivars are the most effective measure of controlling Fusarium wilt, but new races of the pathogen appear to overcome resistance genes in currently grown cultivars. The evaluation of fungicides against collar rot of groundnut caused by Aspergillus niger van Tiegham revealed that all the systemic fungicides were capable of inhibiting the growth of the test fungus at different concentrations as compared to check.
