Weed hosts of Meloidogyne spp. and the effect of aqueous weed extracts on egg hatching

et al. 2019

Summary Weeds have a great economic impact on agricultural production because they compete with crops for resources and are alternative hosts for pests, microbial pathogens and plant‐parasitic nematodes. This study aimed to investigate the susceptibility of weeds to the root‐knot nematodes Meloidogyne javanica and Meloidogyne incognita and assess the effect of aqueous weed extracts on M. javanica egg hatching. Four experiments were conducted, two for each nematode species. Weeds were inoculated with 2000 nematode eggs and grown for 60 days under greenhouse conditions. Soyabean cv. Monsoy 7110 was used as control. The weeds Ipomoea grandifolia, Solanum americanum, Digitaria horizontalis, Amaranthus deflexus, Sorghum halepense and Commelina benghalensis were susceptible to M. javanica and M. incognita in at least one experiment (reproduction factor, RF >1). Crotalaria juncea and Eleusine indica were susceptible to M. incognita in one experiment, and Digitaria insularis, Sida rhombifolia, Bidens pilosa, Urochloa decumbens, Crotalaria breviflora, Cenchrus echinatus, Crotalaria ochroleuca and Crotalaria spectabilis were immune or resistant (RF <1 or RF = 0). Alternanthera tenella, C. juncea, S. rhombifolia, C. ochroleuca, C. spectabilis, C. breviflora, B. pilosa, E. indica, U. decumbens and C. echinatus were resistant or immune to M. javanica (RF <1 or RF = 0). Compared with the control (water), all weed extracts reduced M. javanica egg hatch. Our results highlight the importance of weed control in agricultural systems, as nematodes can survive and multiply in weed roots during the off‐season. Weed leaves and shoots, however, may be an interesting source of compounds with nematicidal activity.

“…and Digitaria insularis (L.) Fedde are known to be susceptible to root-knot nematodes (Mônaco et al, 2009;Silva et al, 2013;Bell e et al, 2017a). Some weed species, however, are non-host to nematodes and have nematicidal activity (Mello et al, 2006;Gardiano et al, 2011;Corbani & Mazzonetto, 2013;. Crotalaria spp.…”

“…A few researches on different plants have already been done, demonstrating nematicide potential of plant extracts. For example, Chenopodium ambrosioides L. (Mashela and Nthangeni, 2002); castor bean (Ricinus communis L.) (Mello et al, 2006), and Azadirachta indica A. Juss (Javed et al, 2008) can produce such as toxic substances. Besides, another plant species exist in the entire northeast region, the Anadenanthera macrocarpa, might present nematicide and/or nematostatic potential due to its efficiency in pest control in agronomic crops (Moura et al, 2012) and veterinary, as in ticks Rhipicephalus (Boophilus) microplusem bovinos (Silva Filho et al, 2013).…”

The black angico (Anadenanthera macrocarpa) contains some phenolic compounds, such as flavonoids and tannins, which are considered as secondary metabolites with antimicrobial properties and can be used in the nematodes management. The experimental design was completely randomized in a factorial (2 x 5) + 1 (leaf and bark x concentrations (20, 40, 60, 80 and 100 g L -1 ) + control water-only), with five replications. The cotton seedlings were inoculated with suspension of 4,400 juveniles and eggs of M. incognita. The extracts were applied on soil in a total of 100 mL per pot, in four installments of 25 mL each, in intervals of 15 days . After 60 days of the extracts application, agronomic parameters and parasitism characterist ics were evaluated. Plant height and fresh mass of aerial part presented considerable gain with application of leaf extracts. All extracts, regardless of concentration, showed independent suppressive effect to M. incognita. The black angico extracts presented potential capacity to control gall nematodes by the presence of metabolite compounds that affect the plants protection. These results reinforce the need of further studies regarding the isolation of chemical compounds with nematicide action.
