“…The discrepancy in results may be explained by differences between the plant varieties used, test conditions and the type of material used (dry biomass vs. seed meal). The presented studies, however, showed a favourable effect of vetch seed meal applied in low (1% and 5%) doses, as this species is not a suitable host plant for the northern root-knot nematode (Dobosz & Krawczyk 2019). In addition to the positive im-pact on the growth and development, it has also been noticed that products made from plant tissues have a beneficial effect on the microbial richness of the soil (Jaffee 2006;Chauvin et al 2015;Chen et al 2019) and the diversity of bacterivorous and fungivorous nematode communities in the soil (Jaffee 2006;Renčo 2021).…”

Meloidogyne hapla is a serious pest of many cultivated plants. In response to the economic significance of the species, efforts are being made to develop a new method to reduce its harmful effects on crops. The aim of the study was to determine the effect of diffusates from seeds of selected species of legumes on the motility of second-stage juveniles and to evaluate the effect of meal from seeds of selected species of legume on the capacity to infect the roots of tomato plants by the J2 stage. The experiment examined the effect of diffusates on the motility of the J2 stage performed in Petri dishes, at temperatures of 10 °C, 17 °C and 21 °C. The evaluation of the J2 stage infectivity was estimated in a pot experiment performed under controlled conditions of 20 ± 1 °C. The pots were filled with sterile substrate mixed with meal from the seeds of selected plants at 1%, 5% and 10% of the substrate weight. The studies carried out in the Petri dishes showed varying effects of the seed diffusates from selected legume plants on the motility of the J2 stage of Meloidogyne hapla. J2 were found to lose their motility within 24 h after immersion in water containing seed diffusates from Melilotus albus, Trifolium pratense T. repens, in the temperature ranges investigated (10 °C, 17 °C and 21 °C). However, in a mixture of seed diffusates and soil filtrate from the root zone of tomato plants, the absence of motility in the second-stage juveniles was observed after 24 h at 17 °C and 21 °C, with seed diffusates from Lotus corniculatus, Medicago sativa, Medicago × varia, Melilotus officinalis, as well as Onobrychis viciifolia, Ornithopus sativus, Vicia sativa, used in the mixture. Galega officinalis Risa (GoR) seed diffusates were found to have an inhibiting effect on the motility of the J2 stage of M. hapla 24 h following the immersion of the J2 stage in the solution of the soil filtrate containing tomato root diffusates, at 21 °C. The J2 stage were not rendered immotile in all the experiment set-ups involving the seeds of V. faba, Lupinus spp., likewise in the control set-ups. In the pots studied, a significant effect of the addition of legume seed meal on the development of M. hapla nematodes and tomato plants was found. The introduction of Lotus corniculatus, Onobrychis viciifolia and Vicia sativa seed meal into the substrate in the proportion of 1%, 5% and 10% resulted in the inhibition of the J2 stage penetration into the roots of tomato plants at temperatures of 17 °C and 21 °C. With the admixture of the M. sativa and T. repens seed meal, within the temperature range investigated, no nematode infection was observed in the roots, regardless of the seed meal content in the substrate. As regards to the fresh weight, tomato plants grown in a substrate containing 1% and 5% of the V. sativa cv. Jaga seed meal were characterised by significantly higher plant weight values as compared to those grown in the control set-up. The obtained results imply that is advisable to expand the scope of research to include other economically im...

“…Particular species of legumes have a different impact on the dynamics of M. hapla development in the soil [44]. The population dynamics of the northern root-knot nematode in the soil under annual and two-or three-year red clover and alfalfa precrop cultivation, involves the host suitability of each of those plant species to northern root-knot nematode, the precrop effects for succeeding crops and the timing of the sampling to determine the abundance of this nematode in soil towards assessing its damage potential to crops.…”

The northern root-knot nematode, Meloidogyne hapla, is a major pest of many crop species. The objective of the study was to determine how M. hapla population dynamics is affected by two precrops, i.e., Trifolium pratense and Medicago sativa, in three crop durations: one, two and three years of continuous cultivation. Moreover, we set ourselves the task of evaluating the effect of the legume precrop soil on the growth of the succeeding tomato plant (Solanum lycopersicum) and on the nematode population. The experiment was performed outdoors in pots with naturally infected soil. Both precrop species investigated were found to modify the J2 nematode population density in the soil. The galls and nematode females with egg masses were observed on the roots of both studied plant species at the end of each growing season. They appeared to be more abundant on the red clover roots than on those of the alfalfa. The obtained data indicate that the spring soil sampling is more appropriate for the estimation of the M. hapla population density in the red clover precrop soil. The legume precrop soil had a limiting effect on tomato growth and fruit yield. The nematode population negatively influenced tomato growth. The experiment revealed that tomato plants could be planted in alfalfa precrop soil following at least three years of continuous alfalfa cultivation. The same cannot be said of the cultivation of red clover as a precrop for tomatoes.

“…Thus resistance techniques should be targeted at limiting female populations since males are absent in most species [ 153 ], except in lesion nematodes, which assume a sexual mode of reproduction. The nematode complex can continue their unabated infection spree on available hosts and thrive for many years [ 61 , 63 , 155 , 156 , 157 ].…”

“…For chemical control, fumigation with dichloropropene-based fungicides and non-volatile nematicides can provide a good control of these nematodes to improve pea yields [ 163 ]. Host resistance efforts, using infested fields and controlled pot experiments show promise [ 157 , 164 , 165 , 166 ]. However, for decades, the interest in plant parasitic nematodes has mainly focused on biological control and host–parasite interactions [ 154 ].…”

“…The management of root knot nematodes requires integrated strategies, including cultural methods of prolonged fallowing [ 157 ], avoiding host plant monocultures and abstaining from areas with secondary host weeds such as alfalfa [ 63 , 167 ]. The beneficial associations of some microbes can be exploited to enhance the availability of nutrients and useful minerals to improve plants’ health and immunity to induce resistance to root knot pathogens [ 114 , 179 ].…”

Pea (Pisum sativum L.) is a grain legume widely cultivated in temperate climates. It is important in the race for food security owing to its multipurpose low-input requirement and environmental promoting traits. Pea is key in nitrogen fixation, biodiversity preservation, and nutritional functions as food and feed. Unfortunately, like most crops, pea production is constrained by several pests and diseases, of which rhizosphere disease dwellers are the most critical due to their long-term persistence in the soil and difficulty to manage. Understanding the rhizosphere environment can improve host plant root microbial association to increase yield stability and facilitate improved crop performance through breeding. Thus, the use of various germplasm and genomic resources combined with scientific collaborative efforts has contributed to improving pea resistance/cultivation against rhizospheric diseases. This improvement has been achieved through robust phenotyping, genotyping, agronomic practices, and resistance breeding. Nonetheless, resistance to rhizospheric diseases is still limited, while biological and chemical-based control strategies are unrealistic and unfavourable to the environment, respectively. Hence, there is a need to consistently scout for host plant resistance to resolve these bottlenecks. Herein, in view of these challenges, we reflect on pea breeding for resistance to diseases caused by rhizospheric pathogens, including fusarium wilt, root rots, nematode complex, and parasitic broomrape. Here, we will attempt to appraise and harmonise historical and contemporary knowledge that contributes to pea resistance breeding for soilborne disease management and discuss the way forward.
