Tomato (Solanum lycopersicum L.) is one of the most important vegetables worldwide. productivity limited by, among other factors, biotic constraints including root-knot nematodes (Meloidogyne species) which lower both quality and quantity crop. Two trials were conducted at Horticulture Research Teaching Field, Egerton University, Kenya, to evaluate effects fresh organic manure slender leaf (Cro...
in this research, 30 sugar beet breeding populations developed by crossing of sugar beet monogerm and multigerm male strile lines with nematode resistant wild sources (w-1009 contaning resistance gene from beta procumbens and w-1010 contaning resistance genes from beta maritima) were compared with resistant and susceptible checks with respect to nematode resistance and yield. the experiments we...
Growth of alfalfa (Medicago sativa cv. Vernal) seedlings was compared after inoculation with combinations of either Pratylenchus penetrans and Fusarium soloni or P. penetrans and F. oxysporum f. sp. medicaginis. A synergistic disease interaction occurred in alfalfa when F. oxysporum and P. penetrans were added simultaneously to the soil. Alfalfa growth was suppressed at all inoculum levels of P...
Intestinal parasitic infestation is a common condition in developing as well as developed countries. According to WHO Global Burden of Disease 2004 report, approximately 150.9 million of world population has high intensity infection by intestinal nematode while 37.7 million people alone from south East Asia are infected. Among developing countries like Pakistan, intestinal parasitic infestation...
The nematode Caenorhabditis elegans is attracted by at least four classes of attractants: by cyclic nucleotides, cAMP and cGMP; by anions, Cl(-), Br(-), I(-); by cations, Na(+), Li(+), K(+), Mg(+); and by alkaline pH values. The nematode's behavioral response to gradients of these attractants involves orientation and movement up the gradient, accumulation, and then habitutation. Comparison of t...
Agrobacterium tumefaciens stimulated and Fusarium oxysporum f. sp. lycopersici inhibited development and reproduction of Meloidogyne incognita when applied to the opposite split root of tomato, Lycopersicon esculentum cv. Tropic, plants. The lowest rate of nematode reproduction occurred after 2,000 juveniles were applied and the fungus was present in the opposite split root. The effects of all ...
abstract in order to identify the plant parasitic nematodes of potato fields, 55 soil samples and 60 infested tuber samples were collected from different fields in khorasan razavi province during 2005-2006 . soil samples were washed and nematodes were extracted by centrifugal flotation technique. according to de grisse, the extracted nematodes were fixed and transferred to glycerin. baermann fu...
