Abstract

The application of Trichoderma spp. for the suppression of plant-parasitic nematode populations is a promising tool in biological control. Sixteen strains of six Trichoderma species (T. atroviride, T. harzianum, T. rossicum, T. tomentosum, T. virens and T. asperellum) were tested in vitro in order to identify the most appropriate strains to control the dagger nematode Xiphinema index. Mortality assays revealed that the strains of the widely investigated T. harzianum species have caused significant reduction of X. index populations, although T. harzianum strains were not the most efficient among all the tested fungi. Certain T. virens and T. atroviride strains and T. rossicum have triggered faster and higher mortality. Generally, our data indicate that Trichoderma species have innate ability to decrease X. index population. Furthermore, as we had difficulties with maintaining X. index in vitro, we successfully used a newly developed method to keep X. index specimens viable during the experiments.

Introduction The genus Xiphinema Cobb, 1913 belonging to the family Longidoridae represents ectoparasitic root nematodes commonly known as the dagger nematode. There are approximately 260 nominal species in the genus to date ( Gutiérrez-Gutiérrez et al ., 2012 ). They are typically divided into two groups, namely X. americanum -group with about 50 species and non- X. americanum -group ( Loof & Luc, 1990 ; Lamberti et al ., 2000 ). The genus Xiphinema includes phytopathogenic species that damage a large number of wild and cultivated plants through

In this context, Martinez et al. (2010) determined that one of the most important problems being faced by modern sport marketeers was the service quality providing the following arguments: the proxy measure of management performance; an important factor in positioning the company; and an essential determinant of customer behaviour variables such as customer loyalty.
