The statistical design for conducting the experiment was CRD. Some of the plant species have been reported to possess harmless eco-friendly chemicals that have growth promoting effect. In the present studies, botanicals were prepared from the leaves of five locally available plants viz. Callistemon lanceolatus, Eucalyptus teriticornis, Azadirachta indica, Tagetes erecta, Aegle marmelos at 20 % and 40 % concentrations and were used for treating corms before planting and then up to harvesting of spike. The present investigations were conducted to know the growth promoting and fusarium wilt disease suppressing effects of botanicals. Present studies revealed that all the ten treatments showed significant differences in growth, yield, physiological and biochemical parameters of plants as compared to control. On qualitative phytochemical analysis of botanicals, it was confirmed that, all the botanicals have steroids and flavonoids. Forty percent concentration of botanicals had more growth promoting effect on plants than 20% concentration. All these botanicals suppressed the fusarium wilt disease of gladiolus to a variable extent. Eucalyptus teriticornis was found as best botanical for fusarium wilt disease suppression. On GC-MS analysis of E. tereticornis botanical, two major antifungal compounds (α-phellandrene and viridiflorol) were found. Among all treatments; E. tereticornis, A. indica and C. lanceolatus were found more effective in growth promotion as well as disease suppression than T. erecta and A. marmelos.ennullEffect of botanicals as growth promoter and fusarium wilt suppressor on gladiolus (Gladiolus grandiflorus L.)Thesis
