| Abstract | A total of one hundred and twenty-six isolates of Fusarium oxysporum f.sp.lycopersici were successfully isolated from tomato plants showing Fusarium wilt symptomsfrom commercial fields at Doi Inthanon national park, Chiang Mai. The isolate FolCK_117was the most virulent isolate due to plant showing wilting or death and selected asrepresentative strain. After that, six strains of soil actinomycetes namely NSP1, NSP2,NSP3, NSP4, NSP5 and NSP6 isolate from the Doi Suthep-Pui national park, Chiang Mai.were tested for ability of growing on glucose yeast malt agar (GYM) mixed withfungicides by the manufacturer recommeded dose include Brodeaux mixture, captan,etridiazole + quintozene, iprodione, mancozeb, metalaxyl and prochloraz. The resultshowed that all actinomycetes could be able grown on GYM mixed with metalaxyl atrecommended concentration (1,000 mg/kg). Moreover, they showed significantly higher oninhibiting the growth of pathogen than actinomycetes growing on GYM. The highestefficacy was given from isolate NSP3, which inhibited mycelial growth and sporulationof fungal pathogen at 84.11 and 94.44%, respectively. In addition, The non-filtrateculture (NF) of actinomyces isolate NSP3 showed the efficiency of 93.89% inhibitingthe conidial germination of pathogen at 6 hr. In all experiments, 2 factorial in completelyrandomized design was conducted. |
