“…Approaches to use biological methods to overcome the infestation of Meloidogyne spp. have been reported by many authors worldwide (Gupta and Sharmaj, 1993;Amarasinghe and Kariapperuma, 2007;Wiratno, et al, 2009;Khali et al, 2012;Khan et al, 2019). Further, Oka et al, (2000) suggested that the essential oils and their main components of aromatic plants cause immobilization of root knot nematodes,…”

Root-knot nematode, Meloidogyne incognita (Kofoid and White) is one of the most destructive plant parasitic nematode species in almost all agriculture and horticulture crops in Sri Lanka. Biologically sound controlling measures against this nematode species has been attempted from long past with ambiguous efficacy. This paper highlights the nemato-toxic potential of crude leaf extract of Annona glabra, and extracellular metabolites of Trichoderma harzianum and T. viride on root-knot nematode species, Meloidogyne incognita infesting in spinach plants under semi-field conditions.Results revealed that nematode infested plants treated with T. harzianum extract showed a significantly higher plant growth together with reduced root galling compared to that of T. viride and A. glabra crude extract. Both T. harzianum and T. viride treatments significantly increased the root growth of the nematode infested plants compared to that of A. glabra crude extract. Annona glabra crude leaf extract at the rate of 125 g/L and fungus mycelium of T. viride and T.

“…Results presented in Table 2 revealed that highest mortality percentages of J2 was found using P. hysterophorus (26,36,42,47, 58 and 80), (29, 39, 47, 51, 67 and 86) and (33,45,51,56, 75 and 91) as well as the least was observed by T. cardifolia (15,23,28,30,37,64 ), (17,28,33,34,33,69) and (27,30,39,39,57,72) at the concentrations of 250, 500, 1000, 1500, 2000 and 2500 µg/ml after 12, 24 and 48 h of exposure period, respectively. On the other hand, aqueous extracts of C. citratus, E. crassipes, and M. deliciosa leaves showed less mortality after 48 h of exposure as compared to P. hysterophorus.…”

The current experiment was performed to determine the nematicidal behaviour of aqueous extract of various weed plants viz., Parthenium hysterophorus, Cymbopogon citratus, Eichhornia crassipes, Monstera deliciosa and Tinospora cardifolia against hatching, mortality and penetration rate of Meloidogyne incognita under in vitro condition. The eggs and second stage juveniles were exposed to various concentrations (250, 500, 1000, 1500, 2000 and 2500 μg/ml) for 5 days and 12, 24 and 48 h respectively. During the experiment, all plant extracts displayed nematicidal potential. Comparison of LC 50 values of different plant extracts showed that P. hysterophorus was found to be most effective with LC 50 664.9 μg/ml, while T. cardifolia was less effective at 48h of LC 50 1419.0 μg/ml. Aqueous extracts of P. hysterophorus at 2500 μg/ml was highly effective against hatching and mortality after 5 days and 72h exposure period respectively. Whereas T. cardifolia was found least effective. The macerated leaves of P. hysterophorus applied at 0.3 g/kg sand showed the lowest penetration of M. incognita in brinjal roots while T. cardifolia displayed highest after 3 and 5 days' post inoculation. This study suggests that aqueous extract of the selected plants having nematistatic and nematicidal properties that can be used for the management of M. incognita in an eco-friendly manner and sustainable agriculture.

“…In the present study population of the three nematodes was significantly reduced along with yield was elevated but at the same time population of bacteria was not altered. Khan et al (2019) reported that leaves of Phyllanthus amarus plant may be used successfully for management of Meloidogyne incognita and could be a possible replacement of synthetic nematicides.…”

The study involves evaluation of two nematicides, namely Turtob-F (a new nematicide) and carbofuran on 3 nematode populations and two bacteria associated with the rhizosphere of brinjal. The effect of the nematicides was observed on the population size of the selected nematodes and bacteria as well as the yield of brinjal crop. All three nematode populations were markedly reduced by the applied nematicides. The bacterial populations (Pseudomonas and Klebsiella) however, remained uninfluenced by the nematicides. The yield of brinjal was found to be significantly elevated (p<0.05).
