EgyptJournal Article20191031A greenhouse trail was conducted to study the influence of five plant dried<br />leaf powders i.e. cabbage, sorrel, spinach, rocket and tomato in comparing with<br />oxamyl on root-knot nematode M. incognita infecting eggplant under greenhouse<br />conditions. All treatments showed remarkable increase in plant growth parameters<br />as well as reduced nematode criteria. Cabbage dried leaf powder showed higher<br />effectiveness of the tested botanical dried leaf powders and enhanced plant growth<br />parameters with significant increase values. On the other hand, spinach dried leaf<br />powder as soil amendments overwhelmed other treatments in suppressing<br />nematode population in soil (78.3%), root galling number (87.0%), egg-masses<br />(91.5%) and eggs / one gram root (91.5%) respectively. However, the least values<br />of the same nematode criteria was achieved by sorrel treatment with values of<br />34.0,77.3,90.5 and 89.3 respectively, comparing to nematode alone. The recorded<br />results showed a potential properties of using such plant dried leaf powders as ecofriendly<br />control method instead of chemical pesticides.<br /><br />https://ejaj.journals.ekb.eg/article_56206_f06dfa6645f6417625f10891871b08f8.pdfEgyptian Society for AgronematologyEgyptian Journal of Agronematology1110-615816120170101Integrated Management of Root-Knot Nematode, Meloidogyne javanica Infected Cucumber and Courgette11205620810.21608/ejaj.2017.56208ENM.Abo-KorahEcon. Ent. & Agric. Zoology Dept., Fac. Agric., Menoufia Univ., Shebin Elkom, EgyptJournal Article20191031This work was conducted to study the effect of nematode – trapping fungus<br />(Arthrobotrys conoides); white wormwood (Artemisia herba alba) and the<br />nematicides, Tervigo (half dose) in the integrated control programs of plant parasitic<br />nematodes. These agents were evaluated alone as well as in combination against<br />Meloidogyne javanica infected Cucumber and Courgette under greenhouse<br />conditions, at the Experimental Farm, Faculty of Agriculture, Menoufia University,<br />Shibin El-Kom, Egypt. The obtained results showed that, the application of A.<br />conoides + Wormwood + Tervigo treatment gave the highest reduction percentage<br />of the nematode with reduction ratio of (85.0%) followed by the treatment of A.<br />conoides + Tervigo (77.3%) in Cucumber plants and the same previous treatments<br />gave (80.0% and 70.5%) in Courgette plants, respectively. Moreover, the two<br />previous applications gave better enhancement in various growth parameters such<br />as, plant height, shoot weight, and root weight in both Cucumber and Courgette<br />plants. The same application gave the lowest gall index (1.0) representing the<br />highest total decrease in gall numbers (-83.3%) in cucumber and (-81.8%) in<br />Courgette compared with control. There are significant differences in root gall index<br />between control treatment and all other treatments. Results indicate that Tervigo as<br />a nematicide had no adverse effects on the predaceous activity of A. conoides.<br />Moreover, dried leaves of Wormwood play an important role in nematode control, as<br />well as it promoting plant growth and enhancing beneficial microorganisms in soil.https://ejaj.journals.ekb.eg/article_56208_34d52959072b54f37a5586e4d96c94a5.pdfEgyptian Society for AgronematologyEgyptian Journal of Agronematology1110-615816120170101Effects of Plant Leaf Extracts on Egg-Masses Hatching and Juveniles Mortality of the Root-Knot Nematode, Meloidogyne Javanica21295719410.21608/ejaj.2017.57194ENA.AananyAgric.

Results indicated that none of the tested potato cultivars was immune to<br />nematode infection since galls or egg masses on root system of such cultivar was<br />recorded and all plant growth parameters were obviously diminished. Among the<br />tested potato cultivars, Spunta showed the highest percentage reduction values of<br />all plant growth characters. Host category of the tested cultivars was determined<br />according to the relationship between host growth response in term of reduction %<br />of whole plant fresh weight and R Factor recorded that Cara and Draga potato<br />cultivars were classified as moderately resistant (MR), whilst potato cvs. Spunta and<br />Solana were rated as highly susceptible (HS) and susceptible (S), respectively.<br /><br />https://ejaj.journals.ekb.eg/article_57200_091cc4a2bce4edf33fefbedd444c5b4b.pdfEgyptian Society for AgronematologyEgyptian Journal of Agronematology1110-615816120170101Plant-Parasitic Nematodes Associated with Forage Legumes Planted in Fallow and into Living Grass Sod39495720510.21608/ejaj.2017.57205ENMahfouzAbd-ElgawadPhytopathology Department, National Research Centre;MohamedEissaPhytopathology Department, National Research Centre;Abd-ElmoneimEl-GindiDepartment of Agricultural Zoology and Nematology, Faculty of Agriculture, University of Cairo,Giza, EgyptGroverSmartDepartment of Entomology and Nematology, IFAS, University of Florida, USA.Journal Article20191106The capability of legumes to fix and provide sufficient nitrogen for crop<br />production has encouraged re-appraisal of cropping systems that utilize relevant<br />forage legumes. However, plant-parasitic nematodes (PPN) can damage forage<br />legumes but differently according to forage legume production systems. Therefore,<br />this study determined the population levels of PPN associated with three different<br />production systems. Different species of forage legumes were planted in fallow soil<br />and into living grass sod of two species; 'Pensacola' bahia grass and 'Tif-81'<br />bermuda grass. Thirteen genera of PPN were associated with one or more cultivars<br />of twelve forage legumes in one or more of three locations in Alachua County near<br />Gainesville, Florida, USA. No significant difference (P ≤ 0.05) was found in the<br />nematode population levels among clover cultivars overseeded in dormant bahia<br />grass or bermuda grass sod. However, when clover cultivars were planted in fallow<br />plots, significant differences (P ≤ 0.05) occurred in population levels of Meloidogyne<br />spp. Also, significant differences (P ≤ 0.05) occurred in populations of Meloidogyne<br />spp. and Criconemella spp. among the three experiments.<br /><br />https://ejaj.journals.ekb.eg/article_57205_dcad1db7c81e7b2c607db57db160832b.pdf
