Özet

41 SUMMARY In this research, the prevalence of Rhlzoctonia solani in Izmir which caused col lor and root rot on carnations and possibilities of chemical control were studied. Results from the experiment are as follows; 1. In the surveys in the circuit of Izmir and the prevalence and incidence of R. solani were found as 89.19 % and 11.93 %, respectively. From the calculations made, the losses which were caused by the pathogen were estimated to be 690.747.000 TL. (with yearly values for Izmir in 1990). 2. In the pathogenicity tests, R. solani isolates which were isolated from the diseased carnation showed were high virulence on carnations. 3. In in vitro tests of fungicides, tolclofos-methyl showed a great effectiveness on the isolates. In terms of effectiveness, flutriafol, benomyl, thiram and çaptan followed tolclofos-methyl respectively. The fact that some of the R. solani isolates could survive despite the highest doses of three most effective fungicides goes to show that control against the pathogen would be difficult in the future. 4. In the experiments to determine the effectiveness of the fungicide in pots, as in the in vitro experiments, tolclofos-methyl was shown to be the most effective chemical to R. solani isolates. Flutriafol and thiram followed this, but benomyl showed different level of effectiveness. Meantime and likewise, çaptan showed the lowest effect to the isolates under the pot conditions as iji vitro. When the results of the experiment were evaluated with Duncan tests from statistical point of view, in effectiveness, tolclofos-methyl formed the first group, flutriafol, thiram and benomyl, the second group, and çaptan which was in the same group as the control, third group. 5. Depending on the results of the experiment, it was42 recommended that tolclofos-methyl should be applied as trans plant water in the phase of planting time of the seedling which was the most critical for disease in the order to be able to control the pathogen. It was also emphasized that other fungicides should be applied as well as tolclofos- methyl. Although flutriafol was found to have a high effectiveness on R. solani, it was concluded that this fungicides should be applied after a wide range of trials. 6. The following are suggested as well as chemical control in order to be effective in the control against R. solani : - For growing carnation, greenhouse soil which has no disease should be used and if necessary, the soil shold be fumigated, - Healty seedlings should be trasplanted, The greenhouse shold be ventilated and the over fertilization should be avoided, The weeds must be controlled inside and around of thegreenhouse, It is necessary to take care of seedling when planting.
