Entomopathogenic Nematode Application in Egypt and Russia: Challenges and Opportunities

Spiridonov
Biocontrol is a safe and environmentally sound alternative to chemicalinsecticides. Current status of entomopathogenic nematode (EPN) research andapplication as bio-pesticide in Egypt and Russia is outlined. Adoption of organicagriculture has induced fundamental changes in organic farmer managementpractices. Therefore, new challenges for organic agriculture to include EPN againstinsect pests in such practices in both countries are discussed. Major impedimentsand solutions for EPN commercialization in Egypt and Russia are presented. Morefinancial, informative, regulatory, and technical support is needed in order to exploitthe potential for increased pest management through EPN applications in bothcountries. We pointed out perceived reasons to develop techniques that exploit thepotential for effective pest management through different EPN application tactics.Local EPN production should be encouraged to eliminate or reduce transport,packaging, formulation and storage costs. Furthermore, local EPNs may be moreadaptive and less expensive without any risk to Egyptian and Russian fauna andflora than imported strains. We addressed also guidelines necessary to increase thenumber of people interested in the activities of EPN application against pestshoping to reap clean and safe agro-products for man and the environment.

The study aimed to use two culture algal Spirulina platensis, Anabaenaazollae, Azolla pinnata and Pleurotus columbinus besides olive mill waste incontrolling root knot nematode, Meloidogyne javanica in banana was monitoredunder both laboratory and commercial greenhouse conditions. Laboratoryexperiment revealed that high juvenile mortality percentage occurred during all theexposure periods of all treatments, the best results were after 72 hr exposure.Spirulina platensis followed by Anabaena azollae, Azolla pinnata, Pleurotuscolumbinus and olive watery extract significantly increased juveniles mortality up to70%after 72h at the highest concentration of 1:10 (85.2, 81.4, 79.9, 73.5, 71.7 and70.1%, respectively).In the productivity greenhouse experiment, the combination of culture filtratesof Spirulina platensis, Anabaena azollae, Azolla pinnata, Pleurotus columbinus andolive mill waste water achieved the highest reduction in the number of totalnematodes in both soil and roots, also in numbers of galls. In addition, allcombinations significantly increased the crop yield of banana plants comparing withthe individual treatment and the control.The combined treatments significantly enhanced the CO2 evolution,dehydrogenase and nitrogenase activities over the control. It could berecommended that application of biological control agents against root knotnematode in banana is preferable to reduce the chemical nematicides inputs.

Histological and Control Studies on Aerial Gall Nematode Infecting Camphor Trees in Egypt
A.
Kella
Histological studies on aerial gall nematode infecting camphor trees,Cinnamomum camphora in Egypt were conducted at the experimental station of theNematology Department, Plant Pathology Research Institute, Agricultural ResearchCenter. Transverse sections in the healthy and infected leaves with aerial gallnematode at early and late infection symptoms of camphor trees were done with theaid of electronic microtome. At early symptoms of infection with nematode, smallgalls with a light green color in the main axon of leaf were observed, meanwhile atlate symptoms of infection, nematode galls transfer to dark green or light red color.Giant cells were characterized with thickened walls and necrosis. Histologicalpreparations of the infected leaves cleared that, giant cells in the early symptomsinfection contain different stages of the nematode, Fergusobia spp. and the insect,Fergusonina spp, while at the late symptoms infection it was found different pores inthe galls where the emergency of the adult insect in the gall was done through it.Control experiments by the nematecide, Vydate 24% L. and the insecticide Pyridan45% L. were applied spraying on the whole plant of camphor or applied in theirrigation water against both of nematode and insect, Fergusobia spp. andFergusonina spp. The obtained results indicated that the mixed treatment of Vydate24% L. at irrigation water and Pyridan 45% spraying on plants recorded the bestresults in controlling aerial nematode galls on camphor trees.

Two types of compost, (plant and animal) as well as furan 10%G wereeffective in reducing Meloidogyne incognita number of galls, nematode reproductionand fecundity. Compost was investigated as amendment for suppressingpopulations of Meloidogyne incognita and increasing plant vigor. The greenhouseand laboratory studies were conducted with mature compost produced in SEKEMorganic farm. Compost extract was prepared by steeping 100 g compost in 200 mltap water and removing biomass with cheesecloth filtration followed bycentrifugation. The supernatant was diluted I: 4 in water, sterile filtered and used asI00% compost extract treatment. In micro well as says, M. incognita J2 activity wereinhibited by all tested compost extract concentrations (25%, 50%, 75% and 100%extract), with >55% inhibition in 100% compost extract after 72h. (Animal and plant)Compost treatments mixed with soil at doses 25, 50,100g/ kg were greatertreatment gave the best result in reducing the nematode reproduction comparedwith untreated check. (Animal and plant) compost suppressing final nematodepopulation values that average 92.18% and 92.54 respectively, at doses 100g/kgsoil compared with nematicide Furan 10% at dose 2g/ kg suppressing finalnematode population values that average 79.10%. Also the used (animal and plant)compost tea at two times 2 days before inoculation and 10 days after inoculationshowed the same results. The highest percentage of reduction in nematode finalpopulation (80.59%) and (82.90%) was noticed in concentration dose100 g/200 cm3water / kg by animal and plant compost tea 2 days before inoculation.All the tested materials significantly suppressed nematode final populationand rate of buildup. In general there were positive correlation between theconcentration used and the obtained degree of nematode management.

The influence of five medicinal plant dried leaf powder extracts i.e. cinnamon,lupine, garlic, onion and wormwood; and yeast extract singly or mixed with yeastextract as foliar spraying applications in comparison with oxamyl on M. incognitainfecting broadbean cv. Sakha 1 plant growth response and nematode criteria undergreenhouse conditions (19±3ºC). Results indicated that all tested applicationssignificantly improved broadbean plant growth characters and reduced nematodeparameters as well. Moreover, all tested concomitant treatments significantly gavebetter results than single one did. Of the single treatments, yeast extract showedthe maximum values in ameliorating plant length, total plant fresh weight and shootdry weight followed by garlic, onion and then cinnamon, whereas lupine plantpowder extract gave the minimum values for the same parameters, respectively.Meanwhile, plant received yeast plus garlic achieved the maximum results inameliorating broadbean growth parameters followed by yeast plus onion extracts,respectively. Moreover, yeast extract overwhelmed other single treatments insuppressing nematode population (74.7%), whereas lupine extract showed the leastvalue of this parameters (36.9%), respectively. Meanwhile, pots received yeastmixed with garlic overwhelmed other integrated treatments in this respect. Chemicalanalysis of N, P, K, total phenol and total chlorophyll in this study was recorded anddiscused.
