Abstract

In safflower Anucop, captan and Mancozeb M-45 were found extremely effective in reducingFusarium oxysporum f.sp. carthami wilt. The seed treatments improved seed germination, seedling vigour and plant stand. Due to these treatments many of the seed-borne fungi failed to express in the normal way. Bioagents formulations viz., Trichoderma harzianum, Bacillus subtilis and Pseudomonas fluorescens reduced the wilt incidence both under greenhouse and field conditions, thereby enhancing the growth of the seedlings. These antagonists significantly reduced the population of Fusarium oxysporum f.sp. carthami, increased the seed germination and seedling vigour. Leaf extracts of Becopa monniera andAdathoda vasica were found effective in the control of safflower wilt. Comparatively B. monniera enhanced the seed germination and quality parameters of plants both under greenhouse and field conditions and also effectively suppressed the wilt up to flowering.

 

Key words: Fungicides, bioagents, plant extracts, Fusarium oxysporum f.sp. carthami, disease management.
