Effects of soil solarization, fumigation with metam sodium, cow manure and their combinations on fusarium wilt of carnation, were investigated using randomized complete block design in three replications in greenhouse condition under artificial inoculation at Mahallat.Region In this study, population density of Fusarium oxysporum was reduced considerably in upper 10cm layer of soil in solarization, fumigation, and combination solarization with cow manure and solarization with metam sodium treatments. During the 9 months after treatments, the amount of fusarium decreased in solarization and metam sodium treatments but increased in combination of salarization and metam sodium and stabilized in combination of solarization and cow manure. The amount of wilt in carnation at end growth season reached to minimum in solarization, metam sodium and combination of solarization and cow manure treatments. Relate of the disease was resemble in combination treatments and fumigation retarded the disease considerably but had not significant different with solarization. Combination of solarization and cow manure had highest amount of flower in plant and vase life. The other quality and quantity properties have not significant different in treatments. In consider to best effect of combination of solarization with cow manure on quality properties of carnation and decreasing of infected plants, this treatment could be a suitable alternative for pre-plant treatment for control of this disease. Key words: Carnation,Cow manure, Fusarium oxusporum, Metam sodium, Soil solarization
