Serada domates yetiştiriciliğinde Kök ur nematodu (Meloidogyne spp.)’na karşı toprak dezenfeksiyonu

Bu çalışma, domatesde kök ur nematodlarına karşı solarizasyonun metam sodium 100 l/da ve dazomet 40 kg/da dozu ile kombine uygulamaların etkileri araştırılmıştır. Denemeler 2014-2015 yıllarında Mersin ili Adanalıoğlu-Yenitaşkent’de üç farklı serada yürütülmüştür. Dazomet toprağa karıştırıldıktan sonra dikim sırtları hazırlanmış ve plastik örtü kapatılmıştır. Metam sodium fumigantı toprağa 2 gün sonra dekara 10 ton su ile uygulanmıştır. Temmuz 2014’de yapılan solarizasyon uygulamasının metam sodium ve dazomet kimyasalları ile kombinasyonunun kök ur nematodlarına karşı etkili olduğu saptanmıştır. Solarizasyonun dazomet ve metam sodium ilaçları ile kombinasyonunun Mart 2015’de bitki köklerindeki urlanma oranları 0 iken, kontrol parsellerinde urlanma oranı 6.84 olarak tespit edilmiştir. Solarizasyon ile dazomet 40 kg/da ve metam sodium 100 l/da ilaçlarının kombinasyonlarında bitkilerin söküm döneminde köklerindeki urlanma oranları 2’nin altında saptanmıştır. Fakat uygulamanın yapılmadığı kontrol parsellerinde ise urlanma oranı sırasıyla 7.4, 7.9 ve 7.6 olarak tespit edilmiştir. Sonuç olarak domates yetiştiriciliğinde entegre mücadele içerisinde dayanıklı çeşitler, toprak solarizasyonu ile fumigant kombinasyonlarının kök ur nematodlarına karşı etkili olduğu saptanmıştır.

Soil disinfestation against root knot nematodes on grown tomatoes in greenhouses

This study was investigated to determine the effect of combined application of metam sodium 100 l/da and dazomet 40 kg/da with solarization against root-knot nematode in tomato. The trials were carried out in three different greenhouses in Adanalıoğlu – Yenitaşkent of Mersin province in Turkey in 2014-2015. Dazomet was mixed into the soil and then beds were prepared, and was covered with plastic. The plots were saturated with drip irrigation before metam sodium was applied. Then, the fumigant of metam sodium was applied 2 days later with 10 tons/da water. In 2014 July, the solarization treatment combined with dazomet and metam sodium was effective against root-knot nematodes. The combined treatment of solarization and two fumigants was detected without any symptoms while control treatment showed 6.84 galling index in March 2015. The 40 kg/da dazomet and 100 l/da metam sodium in combination with solarization had less than 2 galling index at the end of the production season. While the control treatment showed mean galling index of 7.4, 7.9, and 7.6 at the same study respectively. Results showed that soil solarization to the beds combined with dazomet and metam sodium, resistant varieties are effective against root-knot nematodes in tomato in integrated approach.
