“…Chicken manure is very effective in reducing M. incognita egg masses by 56%. e finding of Osunlola and Fawole [106] also indicated that poultry dung at 10 to 20 t/ha was highly effective against M. incognita under the field conditions of sweet potato farms compared to the dung of cow, horse, and goat at 10 to 20 t/ ha. Pedroche et al [107] also reported that the crop residues of broccoli (Brassica oleracea) and the species of fungi like Trichoderma inoculants could decrease the M. incognita population from the host plants.…”

Sweet potato is the seventh-ranked food crop produced after wheat, rice, maize, potato, barley, and cassava in the world. It is the most important root tuber crop in temperate, subtropical, and tropical areas of the world. It is grown for food, income-generating, and jobs for farmers and retailers. The important nutritional substances of sweet potatoes are ß-carotene and anthocyanins. However, the production and its valuable products are limited due to root-knot nematode parasitism. One of the most important destructive species of root-knot nematode to this crop is Meloidogyne incognita. The most destructive stage to sweet potato is at its second juvenile stage (J2). At this stage, it invades the roots and tubers of sweet potato highly in warm sandy soil conditions. It is an obligate plant-parasitic nematode. M. incognita caused significant yield loss to sweet potato in terms of quality, quantity, disturbing the process of photosynthesis and nutrient uptake through the formation of galling, establishing of its feeding sites, or induced galls that contain giant-feeding cells, and cracking of tubers and roots directly. It also reduces the market values of the infected tuber of sweet potato by downgrading the production values. The problem of quality and quantity losses to sweet potato by this pest is one of the major problems nowadays. It caused this problem alone or interaction with other plant-parasitic pathogens or through synergistic of fungi, bacteria, viruses, and others. Therefore, this review paper is focused on the sweet potato M. incognita biology, taxonomy, geographical distribution, and management measures.

“…So, after treatment of composted animal manures with high concentrations of N, the richness of bacterivorous nematodes was observed (Shaw et al, 2019) as a result of tight linkages with microbial and plant activities. The C/N ratio of 15-20 is optimal for the soil microorganisms when amendments are added to a 1% level (Osunlola &Fawole, 2015).…”

A survey of nematode community in grapevine plantations grown in Belbes, Sharqia, Egypt revealed the presence of nine plant-parasitic nematodes genera namely Aphelenchus, Criconemoides, Ditylenchus, Helicotylenchus, Pratylenchus, Meloidogyne, Longidorus, Tylenchus and Tylenchorhynchus; free-living nematodes (FLNs) belonging to the genus Rhabditis and predacious nematodes (PNs) belonging to order Mononchida. Nematodes were found with a different frequency of occurrence and population density. Pratylenchus gained a high population density (PD) followed by Tylenchus, Meloidogyne and Helicotylenchus. A higher prominence value (PV) was found with genus Pratylenchus (190.75) while, the genera Meloidogyne, Tylenchorhynchus and Tylenchus were found with moderate prominence values. Animal manures are effective tools in sustainable soil health and agricultural systems. Therefore, the influence of three livestock manures as feasible practices with BECTO Grow Roots®, a commercial plant growth-promoting bacterium (PGPB) on nematode community and plant growth and fruit yield of grapes, Vitis vinifera L. cv. Flame was undertaken. Soil samples were collected at five-time intervals. Composted animal manures significantly (P ≤ 0.05) minified numbers of plant-parasitic nematodes (PPNs). The greatest effect was recorded with oxamyl after two months of treatments followed by chicken, sheep and cow manure. Conversely, at four and five months after application, animal manures were the most effective. Moreover, a noticeable abundance of FLNs and PNs numbers was detected. The highest increment was achieved in soil amended with chicken manure followed by sheep and cow manure whereas oxamyl reduced numbers of FLNs and PNs as compared with untreated vines. Application of manures against PPNs particularly M.incognita decreased numbers of J 2 /250/soil in vines amended with chicken, cow and sheep manure, respectively and increased numbers of FLNs and PNs. Population densities of M.incognita J 2 /250 g soil were significantly minimized (1.55 J 2 /250 g soil) in blocks amended with commercial rhizobacteria and chicken manure. Maximum total fruit weight and leaf numbers were achieved in vines treated with rhizobacteria +chicken, cow and sheep manure, respectively. This study proved that composted chicken, cow and sheep manure applied alone or in combination with PGPB can be a promising tool for the management of phytoparasitic nematodes, enrichment of FLNs and PNs and improvement of plant growth and grapevine yield.

“…Research undertaken in various countries has shown that organic amendments are beneficial to sweetpotato, as they increase yields, enhance its health-promoting properties and improve post-harvest quality (Antonious et al 2011;Siose et al 2018;Atuna et al 2018). Organic amendments also provide useful levels of nematode control, with a field trial in Nigeria showing that various animal manures, but particularly poultry manure applied at 10 t/ha, markedly reduced the reproduction of M. incognita and also reduced the severity of nematode damage to storage roots (Osunlola and Fawole 2015).…”

Australia produces some of the highest sweetpotato yields in the world but the health of the soil used to produce the crop is declining because it is repeatedly tilled to kill volunteer sweetpotatoes, incorporate cover crop residues and prepare beds for planting. Additional disturbance occurs when the swollen roots are harvested. An on-farm study showed that it is possible to replace this tillage-dominated farming system with an alternative that is not only productive, but is also likely to be sustainable in the long-term. When the soil was amended with organic matter, beds were formed 10 months prior to planting, two cover crops (forage sorghum followed by oats) were grown on the beds, residues from those crops were retained on the soil surface as mulch, and sweetpotato cuttings were planted into the mulched, undisturbed beds using strip tillage, the crop established well and yielded 93 t/ha. The only detrimental effect was that root-knot nematode (Meloidogyne incognita) caused severe damage. In contrast, a trial in the same field showed that when organic amendments were placed in a furrow in the centre of the bed so that the swollen roots were surrounded by the amendment as they developed, nematode control was much better. Sawdust and a mixture of sawdust and chicken litter were the most effective amendments, as they both reduced root-knot nematode populations and the severity of nematode damage, and increased marketable yield by 29%. The wide range of natural enemies found in soil collected from the amended furrow at harvest, and the results of a suppression assay in the laboratory suggested that the soils amended with sawdust and sawdust /chicken litter were biologically suppressive to root-knot nematode.
