“…This nematode, which is able to produce 300 eggs per female, on average (Schmitt & Riggs, 1989), showed production lower than 40 female eggs -1 in races 1 and 6 (30 days after inoculation) and in races 6 and 14 (60 days after inoculation). Similar results were recorded when C. spectabilis, C. juncea, C. mucronata Desv., C. breviflora and C. ochroleuca were used to reduce the egg mass of M. javanica and M. enterolobii, in comparison to results recorded for Rutgers tomatoes, which were used as control (Rosa et al, 2013;Rosa et al, 2015). Data concerning the number of eggs per female did not statistically differ between the other races and the controls, in both assessments.…”

The aim of the study is to assess Crotalaria ochroleuca susceptibility to six Heterodera glycines races. To this, C. ochroleuca seedlings and two soybean cultivars were transplanted and individually inoculated with nematode races 1, 2, 3, 5, 6 and 14. Plants were collected and assessed 30 and 60 days after inoculation. Crotalaria ochroleuca reduced the number of females and the total number of eggs of the races 1, 2, 5 and 6. The reproduction of race 3 in crotalaria was equal to that of soybean cultivars in both assessment periods, whereas race 14 only reduced the reproduction in crotalaria to 60 days. Races 1 and 6 (30th day) and races 6 and 14 (60th day) showed number of eggs female-1 smaller than the controls. According to female index (FI), C. ochroleuca was resistant to races 1, 2 and 5, susceptible to race 3, and showed varying reactions to races 6 and 14.

“…In this case, C. spectabilis may be used as an example, although it reduces P. brachyurus reproduction (Santana et al, 2012b;Rosa et al, 2013;Debiasi et al, 2016). Such activity is attributed to the low attractiveness of the plant or even to its higher resistance to P. brachyurus and P. zeae penetration (Silva et al 1989a;Santana et al 2012a).…”

One of the main phytonematode control alternatives is the use of antagonistic plants in crop rotation or succession systems. Although java legume shows antagonist potential to control Meloidogyne javanica, its reaction to other nematodes was not investigated so far. Thus, the aim of the current study is to assess the penetration and reproduction factor (RF) of M. incognita, Rotylenchulus reniformis and Pratylenchus brachyurus in java, using soybean as control. Plants individually inoculated with 1000 specimens from each nematode were assessed 5, 10, 15, 20, 25 and 30 days after inoculation (DAI) for nematode penetration and development. The RF was assessed under two inoculum levels of each nematode (1000 and 700 specimens) 60 days after inoculation, for M. incognita and R. reniformis; and 80 days after inoculation, for P. brachyurus. Meloidogyne incognita and R. reniformis showed lower penetration and reproduction in java (RF < 1), whereas P. brachyurus showed higher penetration and RF > 1. Thus, the java legume can be considered resistant to M. incognita and R. reniformis, as well as susceptible to P. brachyurus.

“…Beet production can be affected by a series of phytosanitary issues including nematodes belonging to the genera Heterodera and Meloidogyne (Held et al, 2000;Krall et al, 2000;Rosa et al, 2015). Meloidogyne incognita (Kofoid & White) Chitwood and M. javanica (Treub) Chitwood frequently parasite horticultural plants, with gall formation in the tuberous root, resulting in yield and quality losses.…”

“…Despite the proven interaction between root-knot nematodes and beet, there are no known studies addressing its effects on the nutritional value of tubers, nor the antioxidant potential of beet. It is worth mentioning that tubers infected by nematodes are discarded due to changes in their physical characteristics, such as deformation and diameter reduction, and they do not meet the demands of in natura commercialization (Rosa et al, 2015). However, other alternatives can be proposed to minimize these losses, such as extraction of pigments, antioxidants, and other substances (Clifford et al, 2015).…”

The objective of this work was to evaluate the effects of infestation by Meloidogyne javanica on the vegetative development, nutritional characteristics, and antioxidant potential of beet (Beta vulgaris). Inoculation in beet seedlings was performed with 0, 1,000, 2,500, 5,000, and 10,000 eggs and with possible second-stage juveniles (J2) of nematodes. Plants were collected 60 days after inoculation for the evaluation of the nematological and vegetative parameters, the physicochemical composition, and the content and activity of antioxidant compounds. The population levels of M. javanica reduced the mass and diameter of the tuber, comparing inoculum levels of 0 and 10,000 eggs + J2 of nematodes. There was a significant difference for the number of galls and nematodes per root system, with a proportional increase of population density according to the inoculation level. The reproduction factor in all infected treatments was above 1. Although the infection by M. javanica reduced the plant protein content, other compounds, such as betalains, sugars, and phenolics, were not affected. The inoculation by M. javanica negatively affects tuber development, but does not alter the antioxidant potential of beet.
