Örtüaltı Hıyar Yetiştiriciliğinde Sorun Olan Kök-ur Nematodları (Meloidogyne spp.)’na Karşı Kimyasal Mücadeleye Alternatif Mücadele Olanaklarının Araştırılması

Bu çalışma, örtüaltı hıyar yetiştiriciliğinde sorun olan kök-ur nematodları (Meloidogyne spp.)’na karşı kimyasal mücadeleye alternatif mücadele olanaklarını araştırmak amacıyla 2017-2018 yıllarında Kocaeli ilinde yürütülmüştür. Denemeler, saksı denemesi şeklinde tesadüf parselleri deneme desenine göre 8 karakter, 10 tekerrürlü ve 2 tekrarlı olarak gerçekleştirilmiştir. Domates saf kültürden elde edilen ikinci dönem kök-ur nematodu (Meloidogyne incognita) larvaları (L2), Ceylan F1 hıyar çeşidi bitkileri, Hint hardalı (Barassicae juncae), Kadife çiçeği (Tagetes erecta) bitki aksamları, Susam yağı (Nemax®), Trichoderma herzianum Rifai KRL-AG2 4x106 spor/g (T-22 Planter Box®), Arbüskülar Mikorizal Fungus (Endo root®, %23,5 canlı Glomus spp.) ve karşılaştırma ilacı Fenamiphos etken maddeli (Nemasat®) denemenin materyallerini oluşturmuştur. Elde edilen bulgulara göre; kök-ur nematodunun hıyar bitkisinde oluşturduğu urların engellenmesi, topraktaki nematod sayısının azaltılması, daha az yumurta kümesi oluşumu, bitki boyunu artırıcı etkisi, bitki yaş ve kuru ağırlığına, kök yaş ve kuru ağırlığına etkileri bakımından her bir saksıya 50 g Hint hardalı yeşil aksam uygulamalarının etkisi diğer karakterlerdeki uygulamalara göre daha yüksek bulunmuştur. Hint hardalı (B. juncae)’ndan sonra T. harzianum ve Susam yağı karakterleri etkili bulunmuştur.

The Investigation of Altaernative Control Possibilities Instead of Chemical Control Against Root-knot Nematodes (Meloidogyne spp.) in Greenhouse Pepper Cultivation

This study was conducted in order to investigate the alternative control to chemical control against root-knot nematodes (Meloidogyne spp.) which was a problem in greenhouse cucumber growing in Kocaeli (Turkey) province during 2017-2018. The experiments were carried out according to randomized plot design with 8 characters, 10 replications and two repititions as pot trials. The second stage rootknot nematodes (Meloidogyne incognita) larvae (J2) obtained from the pure culture of tomatoes, Ceylan F1 cucumber variety plants, Indian mustard (Barassicae juncae), Marigold (Tagetes erecta) plant components, Sesame oil (Nemax), Trichoderma herzianum Rifai KRLAG2 4x106 spore/g (T-22 Planter Box®), Arbaceous mycorrhizal fungus (Endo root®, 23,5% live Glomus spp.) and the comparative nematicides Fenamiphos (Nemasat®) composed of the experiment materials. According to the findings obtained; it was been found more effective effect of 50 g Indian mustard green component applications in each pot than other characters, in terms of prevention of knots created by root-knot nematodes in cucumber plants, reduction of the number of nematodes in the soil, formation of less egg-cluster, increasing effect of plant height, effects of plant wet and dry weight and root wet and dry weight. T. harzianum and Sesame oil characters were found to be effective after the Indian mustard (B. juncae).
