Abstract
Laboratuvar koşullarında karbendazim, mankozeb ve tebukonazol’ün toprak
solunumu, toprağın mikrobiyal populasyonu, katalaz ve üreaz enzim aktiviteleri üzerine
etkileri 40 günlük inkübasyon süresince belirlenmiştir. Toprak örnekleri inkübasyonun
0, 5, 10, 15, 20, 25, 30, 35 ve 40. günlerinde alınmıştır. Toprak solunumu, katalaz ve
üreaz aktivite fungisidlerden önemli olarak etkilenmiştir. Toprak mikroorganizmalarının
sayımı farklı seçici ortamlarda yapılmıştır. Çalışmada kullanılan fungisidlerden
mankozeb, inkübasyon periyodunun 20. gününde fungi sayısını arttırmıştır.
Karbendazim kullanıldığında ise; inkübasyon periyodunun 20. gününde aktinomiset
sayısı, inkübasyonun 40. gününde ise toplam bakteri sayısında artış belirlenmiştir.
Çalışmamızda, topraklara uygulanan karbendazim, mankozeb ve tebukonazol 40 günlük
inkübasyon süresi boyunca üreaz aktivitesini etkilemiş ve inkübasyon süresinin 25.
gününde üreaz aktiviteyi stimüle etmiştir. Sonuçlar fungisid uygulamalarının toprak
mikrobiyal populasyonu, toprak solunumu, katalaz aktivite ve üreaz aktiviteyi
etkilediğini göstermiştir.

Abstract
The effects of mancozeb, carbendazim and tebuconazole on soil microbial
populations, soil respiration, catalase and urease enzyme activities were determined
through a 40 day incubation period in laboratory conditions. Soil sampling was carried
out after 0, 5, 10, 15, 20, 25, 30, 35 and 40 days of incubation. Soil respiration showed
fluctation with kind of the fungicide. Soil respiration, catalase and urease activity were
significantly (p<0.05) affected from the fungicides. Enumeration of the soil
microorganisms were made on different selective media. The mancozeb from fungicides
used in this study increased the number of fungi at 20th day of incubation period.Carbendazim increased the number of actinomycetes at 20th day of incubation period
and the number of total bacteria was increased at 40th day of incubation period. In this study, in the soils amended with mancozeb, tebucozole and carbendazim in 40th day of incubation period observed urease activity, but stimulation in the activity was recorded
in 25th day of incubation period. It was concluded that fungicide applications affect soil microbial population, soil respiration, catalase activity and urease activity.
