Abstract

The research aims were to know effect of application time of endophytic fungus T. polysporum isolate ENDO-04 and saprophyte T. harzianum isolate SAPRO-07 in increasing induced resistance of several vanili clones to Fusarium stem rot disease and their effects to growth of vanili plants. Experiment was conducted in plastic house of Agriculture Faculty of Mataram University by using Completely Randomized Design with factorial experiment consisted of two factors. Application time of Trichoderma fungi factor consisted of four levels, ie: without application of Trichoderma fungi (control), ENDO-04 fungus was given at the same time with SAPRO-07, ENDO-04 was given two weeks before SAPRO-07 isolate, and ENDO-04 was given four weeks before SAPRO-07 isolate. Vanili clones factor consisted of three levels, ie: Timbenuh NTB clone, Jurang Malang NTB clone, and Malang JATIM clone. The result shows that: application of T. polysporum ENDO-04 isolate given at the same time or two and four weeks before application of T. harzianum SAPRO-07 isolate was effective in controlling Fusarium stem rot disease and can increase induced resistance vanili plants to stem rot disease either on Timbenuh NTB clone, Jurang Malang NTB clone, and Malang Jatim clone. Application of T. polysporum isolate ENDO-04 fungus given at two and four weeks before application of T. harzianum isolate SAPRO-07 fungus was more trigger the vegetative growth (elongation of leaf shoots/spiral shaped) compare to when the two fungi were given at the same time.
