pasteuria penetrans is a bacterial parasite of some plant parasite of nematodes whichcan attach to the cuticle of nematode. differences in attachment of p. penetrans spores to the second stag juvenile (j2) cuticle may provide evidence for nematode cuticle diversity even between different ages of j2s. for investigating this purpose, we studied the effect of different ages of the same population ...

root-knot nematodes, meloidogyne spp., are one of the important plant parasitic nematodes of tomato in the world. the most suitable control method of plant parasitic nematodes is the use of resistance sources and tolerant cultivars. in the earlier studies, the results showed thatonly 2% (19 out of 537 varieties) were resistant and tolerant to the root knot nematodes. in the supplementary studie...

The root system is vital for the cotton plant to absorb nutrients and water from the soil and to anchor the plant. Two important soil-borne pathogens of cotton, Meloidogyne incognita (root-knot nematode), and Thielaviopsis basicola can adversely affect root systems resulting in suppressed growth and less efficient water and nutrient uptake and transport. In fields where these pathogens occur to...

The Nematodes are roundworms that are found in every environment of the earth. While some species are harmful parasites, others play a vital role in nutrient cycle and medical research. Nematode infestation in the fields is poly-specific; however, depending on the agro-climatic conditions, one or two species are dominant over the rest. The present studies attempts to observe and control the roo...

Both the root-knot nematode (Meloidogyne incognita) and the soilborne fungus that causes black root rot of seedling cotton (Thielaviopsis basicola) are widely distributed in cotton field soils in Arkansas. Both of these pathogens are capable of causing significant crop damage and yield loss, primarily through damage to the root systems of infected plants. When root-knot nematode or T. basicola ...

sugar beet (beta vulgaris) is one of the hosts for different root-knot nematode species. in this study, firstly the effect of different inoculum levels including 250+250, 500, 500+250, 750, 500+500 and 1000 second stage juveniles of meloidogyne javanica were evaluated on a susceptible variety named jolgeh. the results showed that all inoculum levels were suitable for infection on sugar beet pla...

The influence of different initial inoculum densities of the root-knot nematode Meloidogyne javanica on the growth of sage (Salvia officinalis), root-knot development and nematode multiplication was investigated 90 days after inoculation under greenhouse conditions. With the increase in the nematode initial inoculum densities, shoot fresh/dry weight, shoot/root length and root fresh/dry weight ...
