Efficacies of application programmes on brown patch disease (Rhizoctonia Solani Kühn.) of turf | Çim alanlarýnda sorun olan kök ve kök boðazý hastalýðýnýn (Rhizoctonia Solani Kühn.) savaþýmýnda ilaçlama programlarýnýn etkinliðinin araþtýrýlmasý

Turkish. Bu çalýþmada, çimlerde her sene sorun olan kök ve kök boðazý hastalýðýna (Rhizoctonia solani) karþý bitki aktivatörü, biyolojik fungisit ve etkili fungisitlerden oluþan ilaçlama programlarý ile saha denemesi kurularak etkililikleri araþtýrýlmýþtýr.Deneme alanýna karýþým çim tohumlarý ile çim ekimi yapýlmýþtýr. Deneme tesadüf parselleri deneme desenine göre 4 tekerrürlü olarak kurulmuþtur. Deneme, 5 programdan (4 ilaç programý + kontrol) ve toplam 20 parselden oluþmuþtur. R. solani etmeni suni olarak inokule edildikten sonra 15 gün ara ile ilaçlamalar gerçekleþtirilmiþtir. Yapýlan uygulamalar sonucunda en iyi etkiyi sýrasýyla 4. program ([Lactobacillus acidophilus fermentasyon ürünü + tolclofos methyl+thiram] + trifloxystrobin), 3. Program (Streptomyces lydicus strain WYEC 108 + azoxystrobin), 2. program (menadiona sodium bisulphite + fosforoz asidi) ve 1. program ([gamma aminobutryric asit L-glutamic asit +yaprak gübresi] + Streptomyces candidus) vermiþtir. Sonuç olarak, bitki aktivatörler ve biyolojik preparatlarýn etkili olmalarý, çevre dostu olmalarý ve kalýntý riskleri olmamalarýndan dolayý bu hastalýða karþý ilaçlama programlarýnda fungisitlerle birlikte yer almalarý gerektiði kanýsýna varýlmýþtýr.

English. It was evaluated that efficacies of the different application programs including plant activators, biological fungicides and fungicides against brown patch (Rhizoctonia solani) disease which is common problem annually on turf areas were tested with field trial. Trial plot was sown with mixed turf seeds. Experiment was set up at random plots design with four replicates. Trial included 5 different application programmes (4 application programmes + 1 control) with total 20 plots. After inoculation of R. solani, applications were made at 15-day interval. In the results of applications, the highest efficacies were obtained from 4th programme ([Lactobacillus acidophilus fermentation product + tolclofos methyl+thiram] + trifloxystrobin)], 3rd programme (Streptomyces lydicus strain WYEC 108 + azoxystrobin), 2nd programme (menadiona sodium bisulphite + phosphorus acid) and 1st programme ([gamma aminobutryric asit L-glutamic asit + leaf fertilizer] + Streptomyces candidus), respectively. Consequently, it was concluded that plant activators and biologic compounds because of having acceptable effectiveness, environmentally friendly, and no residue risk should be included into application programmes along with fungicides in control of this disease.
