Abstract

One of the new methods for plant diseases management is application of plant extracts.Soilborne pathogens fungal are world wide distributed and important phytopathogens. They cause yield losses in tobacco growing countries. The purpose of this study is to evaluate the antifungal activity of plant extracts on soilborne pathogens fungal of tobacco (Rhizoctoniasolani and Phytophthora nicotianae) and determine the best concentration of extracts on antifungal activity. The experiment was done in a factorial design based on completely randomized with three factors and five replications under in vitro condition. The first factors, plant extract (nine plant species), the second factor, solvent (five solvent) and the third factor, concentration (three concentration) were considered. In our previous study, experiments were carried out in pot condition based on factorial design with eight eentreatments and three replications in Tirtash Reaserch and Education Center, in 2013. In this study, the first factor including three plant extracts (catmint, tobacco and thyme), these cond factor, three concentration (0.5, 1 and 2 in 1000), and the third factor, treatment application of method two (spray and drench) were considered. The results indicated that different concentration of crude extracts of catmint, tobacco, thyme, fennel, hyssop and badrashbi have remarkable antifungal activity on the fungi. Methanol is perfect solvent for extraction of antifungal compounds. The maximum inhibitory concentration of eachextracts was 2000 ppm. The results of analysis variance showed that the effect of plant extracts on control of soilborne pathogens fungal of tobacco was significant at 1% level. Inour study, the interactions of "plant extracts × concentration", "concentration × application method" and also, "plant extracts × concentration × application method" was significant at1% level. Comparison of treatments means showed that extracts of both plant (catmit andtobacco) at 0.2% concentration were the best treatments with 80% and 75% inhibition off ungi, respectively.
