“…Results showed that among plant-parasitic nematodes infecting grapes, the rootknot nematode, Meloidogyne spp., was more common in 94.5% of all studied soil samples, followed by Xiphinema and Tylenchorhynchus. Mohamed et al (2017) found similar results in the governorates of Giza, Qualiabia and Behaira. Data also showed that the highest plant-parasitic nematodes associated with guava and olive fruit trees were the root-knot nematode, Meloidogyne which was detected in 61.6 and 91.5% of all studued soil samples, respectively, followed by the stunt nematode, Tylenchorhynchus spp., and the spiral nematode, Helicotyleuchus sp.…”

This survey was conducted in four locations of Ismailia governorate in the north eastern part of Egypt during the 2020-2022 seasons to investigate occurrence, population density and distribution of plant-parasitic nematodes associated with various crops. A total of 440 soil samples, were collected from infested fruit trees viz. grape (Vitis vinifera L.), guava (Psidium guajava L.), olive (Olea europaea L) and pomegranate (Punica granatum L.) and vegetable crops viz. green bean (Phaseolus vulgaris L.), pea (Pisum sativum L.), strawberry (Fragaria ananassa) and tomato (Solanum lycopersicum L.). Ten plant parasitic nematodes genera have been identified. The root-knot nematodes, Meloidogyne had the highest mean density over any nematode taxa in the tested samples. The highest density values of Meloidogyne were recorded on olive, grape and guava trees that amounted to 800, 640 and 200 juveniles/250 g soil. respectively. However, the maximum densities for Tylenchorhynchus were 160, 180, 120, and 120 juveniles /250 g soil for grape, guava, olive, and pomegranate, respectively. The maximum density values for Helicotylenchus were 180, 120 and 40 juveniles /250 g soil for guava, olive and pomegranate, respectively. Other genera were found at low density i.e. Criconemoides, Trichodorus, Xiphinema, Longidorus, and Pratylenchus. The root knot nematodes have been nearly found in all vegetable crops. The maximum densities for Meloidogyne were 600, 200, 240 and 720 juveniles /250 g soil for green bean, pea, strawberry and tomato, respectively. Generally obtained data indicated that plant-parasitic nematodes are considered as a serious threat to such plant species under variable agronomic and climatic conditions that need to further developed and implemented of control measures.

“…21, No.1 (2022) Korayem et al (2014) conducted a survey on the plant parasitic nematodes associated with different plants in North Sinai. Also, Mohamed et al (2017) studied phytoparasitic nematodes associated with different cultivars of grape grown in two types of soil in Egypt. Furthermore, Taha (2018) studied the abundance and distribution of plant parasitic nematodes associated with some different plant hosts including grapes, banana, apples, peach and lemon.…”

This study aimed to identify the most important genera or species of nematodes that associate with some fruit trees and cause remarkable economic losses and to study their seasonal fluctuations in newly reclaimed soil in the city of El-Sadat, Menoufia that focused on four fruit trees, namely orange, mango, grapes and peach. Composite soil samples from the rhizosphere of the tested plants were monthly collected, where the first six months of the year 2017 represented summer period (April 2017 -September 2017) and the others represented winter period (October 2017 -March 2018). Composite soil samples from orange trees variety Naval in summer period revealed that there were four nematode genera or species, Tylenchulus semipenetrans, Pratylenchus spp., Hemicycliophora spp. and Xiphinema americanum associated with citrus (orange) trees, where citrus nematode, was the most common representing 51% of the total parasitic nematodes, followed by lesion nematode, Pratylenchus spp. as 33.8% and the dagger nematode, Xiphinema americanum has the lowest frequency of occurrence (0.1%). As for winter months, the same four previous genera were recorded, but at different frequencies of occurrence %. The most important nematode genera in the soil of mango trees variety Kit were: Meloidogyne spp., Pratylenchus spp. and Criconemoides spp. Root-knot nematodes, Meloidogyne spp. recorded the highest frequency of occurrence% of parasitic nematodes associated with mango trees (45.8%) in summer months, followed by Pratylenchus spp. with 39.7%, while ring nematodes, Criconemoides spp. recorded the lowest incidence (14.6%). As for the winter months, the same three nematode genera in the summer months were recorded, but at different proportions. The most important nematode genera or species in the soil of grape variety Flame Seedless were: Meloidogyne spp., Pratylenchus spp., Criconemoides spp. and Xiphinema americanum. The most important nematode genera or species in the soil of peach trees variety Florida were: Meloidogyne spp., Criconemoides spp., and Xiphinema americanum. Root-knot nematode, Meloidogyne spp recorded the highest occurrence % (54.9 %) of the total parasitic nematode in summer months, followed by Criconemoides spp. (38.6 %), while the lowest percentage was for dagger nematode (6.5 %). As for the winter months, the same three nematode genera were recorded, but at different proportions.

“…It has been estimated that these widespread soil inhabitants cause a yield loss of about 12.3% annually, equivalent to approximately $157 billion dollars [ 3 ]. PPNs have expanded widely in the Egyptian vineyard soils [ 4 ]. Their feeding habit on grapevine roots impairs water and nutrients uptake as well as root and shoot growth, resulting in reduced vine vigor and yield losses [ 5 , 6 ].…”

Meloidogyne incognita population control and nutritional status and productivity of Thompson seedless grapevines managed with different treatments

2020

A two-year field trial was conducted in a vineyard (northern Egypt)cultivated with Thompson seedless grapevines to evaluate the effectiveness of four "alternative" (biological/chemical) treatments, Bacillus megaterium, boric acid, calcium nitrate and chitosan, against the rootknot nematode Meloidogyne incognita (Mi), compared to that of the nematicide oxamyl. The influence of these treatments on plant nutritional status and fruit yield and quality was also assessed. All treatments significantly inhibited Mi reproduction parameters in both seasons, decreasing the numbers of nematode galls and egg masses (roots) and of second-stage juveniles (soil). Oxamyl application resulted in the highest reductions in Mi-reproduction parameters, followed by boric acid, which also showed the highest relative nematicidal efficacy (respect to oxamyl). In the 1st season, the highest fruit yield (10.34 kg/grapevine) was recorded from boric acid-treated plants, followed by that from oxamyl-treated plants (7.50 kg/grapevine); in the subsequent season (2019), oxamyl use led to the highest yield, followed by boric acid + chitosan use (10.04 and 8.62 kg/grapevine, respectively). In both seasons, application of boric acid alone and combined with chitosan enhanced the total soluble solids (TSS)/total acidity ratio in grape juice. All treatments led to higher nutrient contents (leaf petioles) and chlorophyll levels (leaves) as well as enhanced fruit size and weight. We conclude that the tested treatments can be safely applied for nematode management in Thompson seedless grapevines, with positive effects on fruit yield and quality.
