Abstract
Abstract Preparing nematicides and irrigation by non-magnetized water or magnetized water gave different reduction percentages of the estimated nematode larvae of the Root-knot nematodes in the soil of grapevines rhizosphere at different periods from the application. The treatment by the mixture of Biozied 125g+Bioarc125g/100L./9 trees surpassed the other treatments recording 79% and 85.8 reduction on the average of root knot nematode number /250 g soil with the preparation and irrigation by non- magnetized and magnetized water, respectively. While the treatment with Bioarc alone was retarded recording average reduction 53.2% and 62.1% in root knot nematodes population. On the other hand potency of the bionematicides such as Bioarc and Biozied or their mixture increased gradually till the fourth month then declined. With chemical nematicide (Rugby) the reduction in population of root –knot nematodes gradually decreased it. This nematicide reduced nematode clearly in the first month whereas the nematode reduction was 67.4 % and 83.8% with the use of nonmagnetized and magnetized water, respectively. It is worth to mention that preparation of Rugby by magnetized water gave more reduction in root knot nematodes than using of no-magnetized water especially in the first month count whereas the reduction was 83.8 % versus 67.4% with non-magnetized water. Abamectin behaved in the same trend of Rugby whereas their efficiency gradually weakened from 62.2% root-knot nematode reduction after one month to 46.7% after five months from application in usage of non-magnetized water for preparation of nematicides and irrigation
