Meloidogyne javanica and Rotylenchulus reniformis are important nematode pests of pigeonpea. Greenhouse evaluation of 66 accessions of 25 species of Cajanus, Rhynchosia, and Flemingia for resistance to M. javanica based on number and size of galls, galled area of root, and number of egg masses showed resistance to be available in these wild relatives of pigeonpea. Thirty-five accessions had </=...

The species of the genus Meloidogyne are globally distributed and generally induce formation galls or nodules in roots a wide variety plants, due to this; this nematode is known as "Root knot nematode". affected plants show loss turgidity leaves, chlorosis withering, which leads reduction crop yields. In Ecuador, presence several root has been registered, wild cultivated plants. For diagnosis, ...

Root-knot nematodes (Meloidogyne spp.) are considered as one of the main limiting factors in crop production systems. Currently, several eco-friendly root-knot control technologies have been developed, which is biofumigants. The purpose this study was to determine effectiveness biofumigants from Brassicaceae and Non-Brassicaceae nematodes. conducted using a one-factor Completely Randomized Desi...

Background: Root-knot nematodes (Meloidogyne spp.) are the most devastating pests of vegetables, especially in tropic and subtropic regions. Meloidogyne incognita is among major pathogens found tomato crop causes a significant yield loss. This study evaluates resistance susceptible cultivar against root-knot incognita). Methods: A greenhouse was conducted to evaluate or susceptibility nine cult...

The soil fumigant 1,3-dichloropropene (1,3-D) formulated with chloropicrin is viewed as a likely alternative for replacing methyl bromide in Florida when the latter is phased out in 2005. Therefore, it behooves us to learn more about using 1,3-D in deep, sand soils. Two trials were conducted on spring squash to determine the most effective rate of 1,3-D for the control of Meloidogyne spp. Rates...

The study was conducted to determine the occurrence, frequency and density of species Meloidogyne Goeldi, 1892 (Tylenchida: Meloidogynidae) in ware potato cultivation areas Turkey Plant Protection Central Research Institute. Soil samples were taken from Afyonkarahisar (149), Aksaray (69), Bolu (94), Kayseri Konya (127), Nevşehir (91), Niğde (226) Sivas (77) Provinces 2018-2019. juveniles extrac...

Pearl millet, Pennisetum glaucum, has potential as a grain crop in the southeastern United States. Although it is used as a food grain in India and Africa, its primary use in the United States is high quality feed for poultry and livestock (1,6,15). Hybrids adapted to the southeast should be high yielding, resistant to the rust fungus Puccinia substriata var. indica, and early maturing. The two...

Galls induced by Meloidogyne spp. in plant roots are a complex organ formed by heterogeneous tissues; within them there are 5-8 giant cells (GCs) that root-knot nematodes use for their own nurturing. Subtle regulatory mechanisms likely mediate the massive gene repression described at early infection stages in galls, particularly in giant cells. Some of these mechanisms are mediated by microRNAs...

Endoparasitic root-knot (Meloidogyne spp.) and lesion (Pratylenchus spp.) nematodes cause considerable damage in agriculture. Before they invade roots to complete their life cycle, soil microbes can attach to their cuticle or surface coat and antagonize the nematode directly or by induction of host plant defenses. We investigated whether the nematode-associated microbiome in soil differs betwee...
