Abstract:

 This study was conducted with the aim of determining the results of effective fungicides against Rhizoctonia solani AG 4 and their combinations with different doses of activators, as well as identifying an environmentally friendly method of combating the disease using low fungicide doses. The effect of different doses of two fungicides, found to be effective against the fungus in in vitro conditions, in combination with Lactobacillus acidophilus, Arthrobacter sp., and Harpin Protein was initially determined through pot experiments under greenhouse conditions. The effects of two combinations, which were found to be successful in pot experiments, were investigated against the disease under field conditions in Antalya and Ankara. According to the trial results in field conditions, the highest efficacy was observed with the combination of Arthrobacter sp.-ProthioconazoleSpiroxamine at the recommended dose 100 mL da-1, with a percentage of 90.77. This was followed by the combination of Arthrobacter sp.-ProthioconazoleSpiroxamine at a reduced fungicide dose 50 mL da-1, which achieved an efficacy of 88.37. When used alone against the disease, Arthrobacter sp., Lactobacillus acidophilus, and Harpin Protein exhibited low efficacy values of 46.20, 39.73, and 23.40, respectively, placing them at the lower end. As a result, it has been concluded that the application of Arthrobacter sp.-ProthioconazoleSpiroxamine at the 1st lower dose 50 mL da-1 can be effective in combating Rhizoctonia solani AG 4 in turf areas as an environmentally friendly control practice due to the use of low fungicide doses.

 Bu çalışma, Rhizoctonia solani AG 4e karşı etkili fungisitlerin ve bunların farklı dozlarının aktivatörlerle kombinasyonunun sonuçlarını tespit etmek ve düşük dozda fungisit kullanımı ile çevre dostu bir mücadele yöntemi tespit etmek amacıyla yapılmıştır. İn vitro koşullarında fungusa karşı etkili bulunan iki fungisitin farklı dozlarının Lactobacillus acidophilus, Arthrobacter sp. ve Harpin Protein ile kombinasyonlarının etkisi öncelikle sera koşullarında saksı denemeleri ile belirlenmiştir. Antalya ve Ankarada arazi koşullarında ise saksı denemelerinde başarılı bulunan iki kombinasyonun hastalığa karşı etkileri araştırılmıştır. Tarla koşullarındaki deneme sonuçlarına göre  90.77 ile en yüksek etki Arthrobacter sp.-ProthioconazoleSpiroxamine önerilen doz 100 mL da-1 kombinasyonunda bulunurken bunu fungisit dozunun azaltıldığı  88.37 etki ile Arthrobacter sp.-ProthioconazoleSpiroxamine 50 mL da-1 takip etmiştir. Hastalığa karşı tek başına kullanılan Arthrobacter sp., Lactobacillus acidophilus, ve Harpin Protein sırasıyla  46.20,  39.73 ve  23.40 düşük etki değerleri ile sonlarda yer almıştır. Sonuç olarak düşük doz fungisit kullanılmasından dolayı çevre dostu bir mücadele uygulaması olarak Arthrobacter sp.-ProthioconazoleSpiroxamine 1. alt doz 50 mL da-1 uygulamasının, çim alanlarında Rhizoctonia solani AG 4 mücadelesi için etkili olabileceği sonucuna varılmıştır.
