THE IMPACT OF SOLARISATION INTEGRATED WITH PLANT BIO-FERMENTATION ON ROOT KNOT NEMATODES

34238

The impact of different freshly/dried chopped medicinal or aromatic plant materialsas an organic amendment in pot cultures, as well as integrated with solarisation under greenhouse conditions on the root knot nematodes population was evaluated. Results indicated that application of solarisation alone gave good control (72%) but when integrated with different plant materials, the control level increased to 95% with Allium sativum and 90% with Mentha microphylla and slightly less with other plant materials which ranged from75 to 80%. The results of pot experiments revealed that the most significant effect on the number of nematodes was achieved with Tagetes patula followed by Pimpinella anisum,Melia azadirach and Origanium syriacum reaching 0.0, 1.2, 1.2 and 2.5/g of roots,respectively. Total control was obtained with Allium sativum. Origanium syriacum contained the highest amount of essential oil (6%). Results obtained indicated that integrated approachusing solarisaion combined with plant materials could be the best alternative control for the root-knot nematodes.
