EFFECT OF CRUDE EXTRACT GARNEW ON PEACH AND GRAPE INFECTION WITH ROOT KNOT NEMATODE

A pot experiment were carried out during two seasons of 2009/2010 and 2010/2011 under greenhouse conditions in the nursery of hortculture research institute. garnew crude extract of ( artemisia, garlic, chrysanthemum, menthe and marjoram)was tested to control the nematode infection of meloidogyne incognita and meloidogyne javanica on peach and grape .three concentrations of garnew were used ( 0.5% ,5% and10%) to control the both nematode species on peach and grape. the most effective concentration of garnew was 10%. whereas the nematicide ethoprop decreased the nematode soil population by 98.8% at the recommended dose and oxamyl decreased it by 98.1% at the recommended dose. garnew decreased the number of galls ,egg-masses and the developmental stages of the both nematode species on peach and grape by the same level of reduction. results of plant growth parameters indicated that the highest concentration of garnew (10%) has appositive effect on plant growth. mineral accumulation in the leaves or roots of both cultivars of peach and grape was differed according to the concentration of the treatment, but generally increased than the untreated plants. the total protein electrophoresed on one dimension sds-page revealed differences in the intensity of the same protein bands between the treated and untreated plants.
