“…Although the data suggest a positive association between N levels and populations of Meloidogyne spp., the efficiency of nitrogen fertilisers to control this nematode was previously reported (Karajeh & Al-Nasir, 2012, 2014Wei et al, 2012;Patil et al, 2013). Probably the effect of N on nematodes will depend on the source from where it is available in the soil (Sánchez-Moreno & Ferris, 2018).…”

Summary Meloidogyne spp. and Pratylenchus spp. are the most damaging plant-parasitic nematodes to sugarcane and the knowledge of soil characteristics that influence the occurrence of these pathogens can be useful in their management. With the objective to investigate the relationships between soil variables and populations of Meloidogyne spp. and Pratylenchus spp. in sugarcane fields, root-zone soil and root samples were collected from 20 farms located in 16 municipalities in Alagoas state, Brazil. The multivariate regression tree technique was used to model the population density’s response variables for Meloidogyne spp. and Pratylenchus spp. in the root-zone soil and the roots according to sugarcane cultivars, soil organic matter, and soil chemical and physical variables. The results showed the existence of associations between soil factors, sugarcane cultivars and populations of nematodes. Root samples from soils with K > 37.79 mmolc dm−3, Al < 5.93 mmolc dm−3 and sugarcane ‘RB92579’, ‘SP753046’, ‘SP813250’ and ‘SP921631’ showed the lowest Pratylenchus spp. population densities. However, the lowest densities in the root-zone were found in soils with sum of bases > 1.91 mmolc dm−3, Ca:Mg ratio < 1:2 and soil organic matter < 10.7 g dm−3. The lowest population densities of Meloidogyne spp. in roots were associated with sugarcane ‘RB92579’, ‘RB93509’, ‘RB98710’, ‘SP791011’ and ‘SP921631’ and soil aggregate mean diam. > 0.48 mm, while root-zone densities were minimum in soils with P > 28.59 mg dm−3. This information should support further studies to investigate the effect of each variable on populations of Pratylenchus and Meloidogyne.

“…Additionally, a few percent of clay particles in the soil attracts nematode juveniles from far away to plant roots through adsorption of root exudates on their surfaces, this opinion is consistent with what has been reported by Prot and Van Gundyl (1981).This indicates that nematode migration toward the plant roots and afterwards their reproduction are influenced by the soil texture. Naz et al2012)..Moreover, the other soil properties in all areas including Organic matter, E C and pH were in a suitable range for the presence of root knot nematodes (Al-ghamdi,2021).This is also confirmed by Ismail (1998) for organic matter and pH, and by Karajeh and Al-Nasir (2014 ) for E C of the most surveyed soil except in one of the greenhouses of Kamosak and Mastawa locations and it was one of the reasons for decreasing infection criteria in both locations. Olabiyi et al,(2009) indicated also that such pH values are within range necessary for nematode reproduction and survival.…”

The findings indicated that the highest disease incidence (D.I.) was observed in autumn 2021 on cucumber plants grown in the greenhouses of Qustapa, with a rate of 87.5%. This was followed by a D.I. of 70% in the same location during spring 2022 and in the greenhouses of Daraband during autumn 2021.In both growing seasons in Daraband, and in Qustapa during Autumn 2021 more than 100 galls per root system were recorded, indicating a high level of infection and a highest rootknot index (5) . In contrast, no infection (D.I. 0.0%) was found in the greenhouses of Kamosak (Grd Goran) in both growing seasons and in Mastawa location during spring 2022. The results of soil analysis conducted in the surveyed locations revealed that the physical and chemical properties of the soil influence the movement and survival of nematodes. Results of Molecular diagnosis using two universal primers included 10 Picomoles (pmol) of forward primer-TW81 (5'GTTTCCGTAGGTGAACCTGC-3') and 10 pmol reverse primer-AB28 (5'ATATGCTTAAGTTCAGCGGGT-3') identified four species of root-knot nematodes Meloidogyne spp., prevalent in cucumber greenhouses across the surveyed locations.namely. M. incognita, M. javanica, M. arenaria and M. hapla and according to their genetic variation two races for each of the first three species were recorded for the first time by this technique.

“…Application of ammonium fertilizers has shown nematicidal effect on plant-parasitic nematodes ( Sudirman and Webster, 1995 , Rodriguez-Kabana et al, 1982 , Zhen-yue et al, 2013 ). Egg-hatching and viability of M. javanica larvae were greatly reduced when NH 4 Cl, (NH 4 ) 2 SO 4 and NH 4 NO 3 were used at elevated levels of EC, and there was a reduction in rate of nematode infection after their use on cucumber under greenhouse conditions ( Karajeh and Al-Nasir, 2012 ).…”

Experiments were conducted in laboratory and pot conditions to determine the effects of urea, di-ammonium phosphate (DAP), single super phosphate (SSP), muriate of potash (MOP) and zinc sulphate (ZnSO 4 ) on hatching of Heterodera avenae . Two concentrations of each fertilizer were tested in lab for which 10 cysts and 5 ml of each concentration were taken in 5 cm diameter Petri plates. Observations were recorded at weekly intervals up to six weeks. Urea, DAP, SSP and MOP inhibited hatching and ZnSO 4 increased it. After six weeks, hatching was least (5.45%) in higher dose of urea and greatest (46.9%) in higher dose of ZnSO 4 . In pot experiment, two doses of urea and single dose of SSP, MOP, and ZnSO 4 were applied in H. avenae -infested soil and WH-1105 wheat was sown. Observations on nematodes in roots, soil and remaining cyst contents were recorded 40 days after sowing. Among all the fertilizers, least nematodes in soil and roots were found at higher dose of urea and greatest number in ZnSO 4 .
