Abstract

This study was conducted to evaluate the efficiency treatments namely the pesticide Tervigo 20SC and some bio control fungi Trichoderma harazianum , Paecililomycis lilacinus  and Nematron formulation and pomegranate peel powder compared with nematicide Vydate10/L against root-knot nematode Meloidogyne spp under greenhouse conditions in September 2016 in Kirkuk governorate. The results showed efficiency of all treatments in reducing the symptoms of the root-knot nematode and improve the growth characteristics of cucumber, Tervigo was the superior in reducing root nodes and nematode population 61.37% and 80.48% compared with control treatment, while T. harazianum was the least 43.19% and 52.58% . The effect of bio control fungi and plant organic formulation were similar effective. All treatments positively contributed in improvement of shoot system for infected and non-infected plants, Nematron , pomegranate peel powder and Tervigo were achieved highest increase in plant length, Tervigo and Nematron were the superior in increase rate of fresh and dry shoot weight and weight of fruits resulting in 54.24 and 33.11% for non-infected plants and 345.45 and 311.91% respectively, for infected plants compared with control treatment. All treatments had a positive effect in increase root system length except, Vydate which had a negative effect by 0.46% , Which led to reduced fresh and dry root weight for infected plants, except Nematron, which increased the rate of fresh and dry root weight compared with control treatment .
