Seralarda Kök Ur Nematodlarına (Meloidogyne spp.) (Nematoda: Meloidogynidae) Solarizasyon ve Toprak Fümigasyon Kombinasyonunun Etkisi

Abstract

Root knot nematodes are economically important crop pests that is difficult to control. Soil fumigation and solarization are significant methods to control root knot nematodes. The application of soil fumigation and solarization on nematodes is not fully understood. Therefore, this study was carried out to determine the effect of the combination of the solarization with reduced dose of metam-sodium to control root knot nematodes in pepper. Experiments were conducted in greenhouses in Adanalıoğlu and Kazanlı region of Mersin province in 2014-2015. Following the planting beds were prepared in the experiments, the solarization with reduced metam-sodium fumigant was applied at 750 l/ha. The plots were saturated via drip irrigation, and waited for two days before metam-sodium was applied with 100 ton/ha water. The solarization application in July 2014 combined with reduced metam-sodium treatment were effectively protected pepper against root-knot nematodes until July 2015 where gall formation ranged between 0-1.4. Solarization combination with reduced metam-sodium application resulted with gall formation below 2 while in non-treated parcels were ranged from 6.4 to 7.1. Solarization with reduced metam-sodium application resulted 98,8% to 234,5% yield increase in pepper. Results indicate that combination of solarization with reduced metam-sodium application reduced the root-knot nematodes. It is thought that when the manufacturers apply the solarization with combination of metam-sodium correctly, they will not have nematode problems and the possibility of encountering lower ineffectiveness of the chemicals.
