Trials were conducted in the 2017-2018 production season. Metam sodium 500 g / l (MS) (50, 75, 100 l / da) in 2 tomato greenhouses in Mersin-Adanalıoğlu, 3 doses, 4 replications were applied before planting. Tomato wilt and root rot (Fusarium oxysporum, Rhizoctonia solani) effect on the disease rate (%) S + MS 50, 75, 100 l / ha applications 66.65-73.69%, 84.91-90.00%, 89.98-92.26, respectively 47.58-56.79% in solarization alone application, 88.23-91.43% in comparison application (S + dazomet, 97%, 40 kg / da) (P <0.05).
Application doses of metam sodium 500 (MS), metam potassium 500 (MP), dimethyl disulfide (DMDS) fumigants (100 l/da, 100 l/da, 60 kg/da) and solarization application in strawberry production area in Mersin-Silifke combined with half doses (50 l/da, 50 l/da, 30 kg/da). The effects of fumigant applications, MS100, MP100, DMDS60, on root rot and wilt disease in strawberry (Macrophomina phaseolina, Fusarium spp., Rhizoctonia solani, Alternaria alternata, Aspergillus niger) were determined as 53.86%, 71.82%, 67.30% in the half doses by 81.75%, 85.29% and 90.55% solarization respectively (P < 0.05).
In tomatoes, S, S+MS50, S+MS75, S+MS100, S+D40, average yield in control applications 5.2, 6.5, 7.7, 8.0, 7.9 and 4.3 kg / m2, strawberries in control 3.0-3.5 tons / ha, with solarization in the plots where fumigants were applied together, it increased as 4.5-5.0 ton / da (P < 0.05).
It was determined that the combination of solarization and fumigants in tomato controls the output of soil-borne diseases adequately and increases the yield, whereas the recommended doses of fumigants in strawberries are more effective than the half-doses applied with solarization, but the yield increase is close in all applications.
