“…In other studies, urea might be lethal for juvenile, immature and mature earthworm of Eisenia foetida , by the mechanism of skin infiltration [ 29 ] and also toxic for filarial vector mosquito, Culex pipiens [ 30 ]. Some investigators observed that inorganic fertilizer (N-P-K) had potential to suppress cereal cyst nematode, Heterodera avenae population [ 31 ] as well as root-knot nematode population [ 32 - 36 ].…”

Aim:The effects of N-P-K fertilizers in the form of urea, single super phosphate and muriate of potash on development of free-living stages of Haemonchus contortus were studied.Materials and Methods:Five parasite free experimental plots of 1 m×1 m area, each of paddy leaves (15-day-old) and an equal number of Cynodon dactylon grass were infested with about 10×104 eggs/ml phosphate buffer saline along with the application of the calculated amount of fertilizers solution. On the 10th day of posttreatment, the pasture was cut, processed, larvae recovered by Baermann method and counted, which was expressed as number of L3 per kg dry matter (DM) of pasture.Results:The average recovered population of L3 of H. contortus per kg DM varied significantly (p<0.05) between the paddy leaves (5933.57±22.718) and Cynodon grass (4861.00±22.718). When different doses of chemical fertilizer and their impact on different pasture were analyzed for control (T-1, 0-0-0 kg/ha N-P-K), the mean L3 recovery per kg DM of paddy (19512.7±50.80) was more than that of Cynodon grass (16540.9±50.80). Larvae recovery per kg DM for different pastures under treatment were in decreasing order as follows: T-2 of paddy (6981.33±50.80, 35.77%), T-2 of Cynodon (5545.38±50.80, 33.52%), T-3 of paddy (317378±50.80, 16.26%), and T-3 of Cynodon (2218.72±50.80, 13.41%) which showed significant difference (p<0.05) among the treatments. In T-4 (paddy) and T-5 (Cynodon), the average number of recovery of larvae was nil implying no significant variation (p>0.05).Conclusion:This study shown that when N-P-K fertilizers administered at recommended level, significantly reduced larval translation of H. contortus minimizing pasture infectivity for the free range grazing animals.

“…Amendments with urea provide additional benefits in suppressing the M. incognita population, as shown in our study. Previous reports have shown that urea and ammonia-releasing fertilizers are effective in controlling plant-parasitic nematodes (Santana-Gomes et al, 2013, Seifi and Bide, 2013, Al-Hazmi and Dawabah, 2014). …”

A greenhouse study was conducted to compare the relative efficacy of different approaches to managing on green bean. These approaches included chemical (fumigant, non-fumigant, seed dressing, and seed dip), biological (the egg-parasitic fungus, and the mycorrhizal fungus sp.), physical (soil solarization), and cultural (chicken litter and urea) methods. Accordingly, nine different control materials and application methods plus nematode-infected and non-infected controls were compared. Two important parameters were considered: plant response (plant growth and root galling) and nematode reproduction (production of eggs and the reproduction factor Rf). The results showed that the use of chicken litter as an organic fertilizer severely affected the growth and survival of the plants. Therefore, this treatment was removed from the evaluation test. All of the other eight treatments were found to be effective against nematode reproduction, but with different levels of efficacy. The eight treatments decreased (38.9-99.8%) root galling, increased plant growth and suppressed nematode reproduction. Based on three important criteria, namely, gall index (GI), egg mass index (EMI), and nematode reproduction factor (RF), the tested materials and methods were categorized into three groups according to their relative control efficacy under the applied test conditions. The three groups were as follows: (1) the relatively high effective group (GI = 1.0-1.4, Rf = 0.07-0.01), which included the fumigant dazomet, the non-fumigant fenamiphos, soil solarization, and seed dip with fenamiphos; (2) the relatively moderate effective group (GI = 3.4-4.0, Rf = 0.24-0.60), which included seed dressing with fenamiphos and urea; and (3) the relatively less effective group (GI = 5.0, Rf = 32.2-37.2), which included and sp.

“…Research has revealed that the diversity and density of soil nematodes can change depending on the fertilization type used in fields ( Liang et al, 2009 ; Diacono and Montemurro, 2010 ; Al-Hazimi and Dacbah, 2014 ; Hu et al, 2014 ). Nitrogen fertilization significantly enhances the contents of soil ammonium and nitrate nitrogen, which have the potential to negatively impact soil nematodes ( Zhao et al, 2014 ; Song et al, 2015 ).…”

“…Similarly, negative effects upon soil nematodes were observed when a high level of phosphate fertilizer was applied in forest soils ( Zhao et al, 2014 ). Specifically, adding urea or calcium superphosphate alone can significantly inhibit the abundance of CCN ( Yang et al, 2008 ; Al-Hazimi and Dacbah, 2014 ). Ammonium sulfate fertilizer was found to significantly limit the abundance of soil nematode communities ( Ikoyi et al, 2020 ), whereas potassium sulfate promoted the occurrence of CCN-associated disease in wheat plants ( Yang et al, 2008 ).…”

Heterodera avenae (cereal cyst nematode, CCN) infects wheat and other cereal crops and causes severe losses in their yield. Research has shown that CCN infestations can be mitigated by organic fertilization in wheat fields, but the mechanisms underlying this phenomenon are still largely unknown. In this study, the relationships among CCN, soil properties, and soil fungal communities with organic fertilizer (OF) or chemical fertilizer (CF) and without fertilizer (CK), were investigated for two years in a wheat field in Henan province, China. Our results showed that the concentrations of soil total N, total P, available P, available K, and organic matter were all promoted by the OF treatment at the jointing stage of wheat, coinciding with the peak in egg hatching and penetration of wheat root by CCNs. Soil total N correlated positively (R 2 = 0.759, p < 0.05) with wheat yields but negatively (R 2 = 0.663, p < 0.01) with Pf/Pi (index of cyst nematode reproduction), implying the regulated soil property contributes to suppressing CCN in the OF treatment. Furthermore, fungal community α-diversity (Shannon and Simpson) and β-diversity (PCoA) of rhizosphere soil was improved under the organic fertilizer treatment. The fungal genera negatively associated with the Pf/Pi of CCN were highly enriched, which included Mortierella and Chaetomium , two taxa already reported as being nematophagous fungi in many other studies. These two genera were heavily surrounded by much more related fungal genera in the constructs co-occurrence network. These results suggested that the OF treatment shifted soil fungal community functioning towards the suppression of CCN. Taken together, the suppressed cyst nematode reproduction with the assembly of fungal communities in the rhizosphere led to greater wheat yields under organic fertilization. These findings provide an in-depth understanding of the benefits provided by organic fertilization for developing sustainable agriculture.
