“…Most plant species studied here have previously shown potential to reduce Meloidogyne populations, including C. spectabilis (Miamoto et al, 2016), U. ruziziensis (Dias-Arieira et al, 2009), millet (Nascimento et al, 2020;Chidichima et al, 2021), and oat (Marini et al, 2016;Carraro-Lemes et al, 2020). The referred studies evaluated the efficiency of these plant species as cover crops, with or without green manure deposition, and, often, the effects of crops were attributed to their being antagonists or bad hosts to nematodes.…”

Root-knot nematode management requires the adoption of integrated practices. Biological agents and cultural control practices are the most widely used, but little is known about their combined effects. This study aimed to assess the interaction effects of the biological agents Trichoderma harzianum + Purpureocillium lilacinum and different green manures on the control of Meloidogyne javanica in soybean under greenhouse conditions. Green manures from white oat, Urochloa ruziziensis, Crotalaria spectabilis, millet, and buckwheat were grown separately and applied onto the soil surface. Subsequently, soybean seeds were treated with the biological agent and planted. The experiment was repeated twice to confirm the results. In Trial 1 and 2, application of green manure or biological treatment alone was efficient in reducing nematode populations. In Trial 1, there was an interaction between factors on total nematode number and number of nematodes per gram of root. Combined use of biological control with white oat and millet green manure produced great results, since when associated with the biological one, the reduction in the total number of nematodes was potentiated by 55 and 49%, respectively (Trial 1). There was no interaction between green manure and biological factors for Trial 2, and the best results were observed with green manures of C. spectabilis, U. ruziziensis and white oat, with a reduction in the population density of the nematode in 60, 59 and 44%, respectively. It is concluded that green manure application and T. harzianum + P. lilacinum were effective in reducing nematode populations when applied separately. White oat and millet green manures associated with T. harzianum + P. lilacinum increase thecontrol of M. javanica in soybean.

“…(Melo et al, 2022). In a study assessing the response of green manure to M. javanica populations, Chidichima et al (2021) observed a reproduction factor (RF) of 2.94 to 53.46 on buckwheat, explaining the large nematode population in soybeans grown in succession to buckwheat.…”

“…Cajanus cajan was shown to reduce M. javanica populations (Miamoto et al, 2016) and is used as a nematoderesistant standard, with reproduction factor (RF) values of 0.11 to 0.13 (Araújo Filho et al, 2010). Chidichima et al (2021), however, observed RF values of 0.58-2.99 that varyied according to M. javanica populations, suggesting a controversial antagonistic effect of C. cajan (Miamoto et al, 2016) attributed to the different behaviors of cultivars (Araújo Filho et al, 2010).…”

Nematodes are among the main plant parasites affecting Brazilian agriculture. Management practices involving the use of antagonistic or non-host plants are crucial for combating Meloidogyne javanica populations in the country. However, there is still limited information on the effects of herbicides on nematode populations. The aim of this research was to evaluate the impact of herbicides applied to crops on M. javanica populations in soybean and to examine the direct effect of herbicide products on the hatching of nematode juveniles. We conducted greenhouse and in vitro experiments. In the greenhouse experiment, soybean plants were grown in pots with sterile substrate, and a soybean seed was inoculated with 2000 nematodes per plant. The plants grew for 60 d, after which they were cut, and the following cover crops were planted: Crotalaria spectabilis, pigeon pea (Cajanus cajan), Stylosanthes, and buckwheat (Fagopyrum esculentum) for 60 d. These cover crops were desiccated with one of the following three herbicides: fomesafen, chlorimuron, or bentazone. Subsequently, soybeans were replanted and cultivated for additional 60 d. In vitro assays were used to determine the hatching percentage of M. javanica eggs exposed to herbicides. Both tests were repeated at different times of the year (Trials 1 and 2). Meloidogyne javanica reproduction was higher on soybean crops grown when buckwheat was a cover crop. Herbicide application reduced total nematode numbers in soybean grown in succession to buckwheat compared with the untreated control. The vegetative development of soybean crops was negatively influenced by herbicide treatment of cover crops, especially with the use of chlorimuron. Bentazone and fomesafen did not affect nematode hatching in vitro.

“…compared to susceptible varieties. However, the effectiveness of this resistance can be associated with different factors, such as, pathogen population density, the state of homozygous and heterozygous of the resistance loci and soil temperature; temperatures greater than 28 °C result in a decrease of the effectiveness of Mi-1 gene (Özalp and Devran, 2018;Chidichima et al, 2021). High initial population densities not only affect crop yield and fruit quality, but interfere with the level of resistance conferred by the Mi-1 gene.…”

The root-knot nematode Meloidogyne spp. causes yield losses of up to 68% on tomato (Solanum lycopersicum L.) crops. Genetic resistance in the host plant makes the crop sustainable and it can breakdown when there is a high population density of the pathogen. The objective of this study was to determine the nematode population density that allow determining the resistance potential of tomato germplasm associated with the Mi-1 resistance gen. The Mi-1 gene was evaluated with the molecular marker SCAR Mi-23 and specific primers in the genotypes COLY007, IAC1687, LA0445, IAC1622 and two commercial controls (susceptible and resistant). The damage scale and the number of individuals recovered (eggs and juveniles) were assessed, with different population densities of the pathogen inoculated (0, 1000, 2000, 3000, 4000 and 5000 individuals plant -1 ), in a split plot design, with six replicates and a plant as the experimental unit. The genotype IAC1687 and the resistant commercial control presented the resistance allele of the Mi-1 gene and were classified as moderately resistant to a density of 1000 individuals plant -1 . Despite having the Mi-1 gene, the COLY007 genotype was classified as moderately susceptible and with densities greater than 1000 individuals plant -1 can break resistance in all genotypes evaluated. Additionally, it is necessary to correlate the genotypic and phenotypic responses to guarantee the success of the selection supported by molecular markers such as SCAR Mi-23 and identify promising genotypes that could be included in a long-term breeding and also used as rootstocks in an integrated management of root-knot nematode.
