(Received: June 6, 2013; Accepted in Revised Form: Nov. 13, 2013) Abstract: Although medical wastewaters are considered as hazardous, little attention is paid to their proper management and disposal. This study conducted on two typical educational hospitals with 300 and 220 beds capacity for parasite cysts and Ova reduction by the hospital wastewater treatment plants. Samples were collected fro...

Plant parasitic nematodes (PPNs) are obligate biotrophic parasites causing serious damage and reduction in crop yields. Several economically important genera parasitize various crop plants. The root-knot, root lesion, and cyst nematodes are the three most economically damaging genera of PPNs on crops within the family Heteroderidae. It is very important to devise various management strategies a...

Root-knot nematodes cause physiological and anatomical disorders in plants. The present study contains the results of an investigation of the effect of Meloidogyne incognita race2 on the growth of roots and aerial organs of tomato under greenhouse conditions. The experiment in a completely randomized design split split plot on two susceptible (Falat Y) and tolerante (Gina VF) tomatoes variety w...

Root-knot nematode (RKN) Meloidogyne incognita is an economically important pest of crops. Pasteuria penetrans, is a nematode hyperparasitic bacterium capable of suppressing the reproduction of RKN and thereby useful for its management. Secreted fatty acid and retinol-binding proteins are unique in nematodes and are engaged in nutrient acquisition, development and reproduction; they are also a ...

Multiple Brassica species commonly grown in Georgia were evaluated as a potential alternative to methyl bromide for management of root-knot nematode in vegetables. Brassica species produce general biocides called glucosinolates and were grown as cover crops and incorporated as green manures prior to transplanting of vegetable crop. Nematicidal activity of the Brassica species was based on net c...

The objective of this study was to determine if planting cotton into the space between the previous year's rows reduces crop loss due to Meloidogyne incognita compared to planting in the same row every year. Row placement had a significant (P </= 0.05) effect on nematode population levels only on 8 July 2005. Plots receiving 1,3-dichloropropene plus aldicarb had lower nematode population levels...

A simple and applicable technique was developed for the detection of soil infestation with rice rootknot nematode, Meloidogyne graminicola by farmers themselves at their fields. The collected soil samples from root-knot nematode infested fields were diluted by adding sterilized sand in the ratio of 1: 1, 1: 3, 1: 7, 1: 15, 1: 31 and 1: 63 and sown with sprouted rice seeds (cv MUT 7029) for dete...

Root-knot nematodes (RKN) are obligatory plant parasitic worms that establish and maintain an intimate relationship with their host plants. During a compatible interaction, RKN induce the redifferentiation of root cells into multinucleate and hypertrophied giant cells essential for nematode growth and reproduction. These metabolically active feeding cells constitute the exclusive source of nutr...

A field inoculation method was developed to produce Meloidogyne spp. infestation sites with minimal quantities of nematode inoculum and with a reduced labor requirement compared to previous techniques. In a preseason-methyl bromidefumigated site, nematode egg suspensions were delivered at concentrations of 0 or 10(x) eggs/m of row where x = 2.12, 2.82, 3.52, or 4.22 through a drip line attached...
