“…Females fecundity in terms of the number of egg masses and the number of eggs/single egg mass was significantly (P<0.05) reduced by all treatments compared to untreated plants. Previous studies revealed that combination of biocontrol agents provides effective control of root-knot nematodes in pot and field experiments (Ashraf and Khan,2008;Murslain et al, 2013Murslain et al, & 2014Udo et al, 2014;El Deriny, 2016). The invasion and development of M. javanica on eggplant were greatly affected with standard concentration of combined application of M.oleifera and Trichoderma harzianum (Murslain et al, 2013).…”

“…The invasion and development of M. javanica on eggplant were greatly affected with standard concentration of combined application of M.oleifera and Trichoderma harzianum (Murslain et al, 2013). Meanwhile, Udo et al (2014) reported that double inoculation with P. lilacinus in combination with Lantana camara leaf extract changed the susceptibility of the tomato cultivar and was the most effective treatment in gall and egg mass inhibition, growth enhancement and dry matter accumulation. Chemical analysis of Moringa plant extracts (Ethanolic and Aqueous leaf extracts) indicated the presence of the active ingredients i.e.…”

Two greenhouse pot experiments were conducted to assess the effectiveness of dried leaf powder and extractives (ethanolic, and aqueous extracts) of Moringa (Moringa oleifera) or organic fertilizer (vermicompost) and two commercial products namely BioNematon (Purpureocillium lilacinum) and Abamectin, Gold (Streptomyces avermitilis) on eggplant growth parameters and Meloidogyne incognita infection. In both experiments observed data revealed that combined applications showed better performance than did single ones. Eggplant growth parameters in terms of fresh shoot and root lengths, and shoot and root weights were remarkably improved with single application of Abamectin or BioNematon followed by plant extracts or vermicompost resulting in a significant (P<0.05) suppression in nematode population in soil and root as well as the number of galls and egg masses. However, the potential of bioagent was increased with the addition of Moringa leaf powder and significantly (P<0.05) enhanced eggplant growth and suppressed nematode population, root galling and female fecundity even no significant differences were recorded compared to Oxamyl. Vermicompost derived from municipal wastes showed a low C/N ratio (1:14) with an excess of nitrogen that exhibited nematicidal activity against M.incognita. The addition of vermicompost with such bio-agents showed a synergistic effect upon nematode population, root galling and number of females. Significant differences whether in plant growth or nematode reproduction were not detected compared to Oxamyl. Thus the current study revealed the potential of leaf powder and extractives of Moringa, vermicompost, P.lilacinum and S.avermitilis as safe alternatives to control M.incognita infecting eggplant through an integrated management program and bring sustainability to agriculture.

“…This might be due to the nematicidal activity of aqueous leaf extract of L. camara against M. incognita as indicated by the reduced galling and eggmasses production. Udo et al (2014) also reported that nematostatic properties of L. camara leaf extract were attributed to poor coordination and orientation of infective juveniles towards the plant roots. Among the different treatments, combination of leaf extract of lantana and tomato-mustard intercropping was the most effective in reducing galling intensity and nematode population followed by combination of leaf extract of lantana and tomato-garlic intercropping.…”

Root-knot nematode, Meloidogyne incognita, is the major limiting factor in tomato production in many regions of the world, including Ethiopia. Hence, there is a need for development of root-knot nematode management methods that are cheap and environmentally friendly. A greenhouse experiment was conducted with an objective to evaluate the integrated effect of botanicals and intercropping against M. incognita on tomato. The experiment was laid out in a 2×3×3 factorial completely randomized design (CRD) with four replications. About 30 ml of lantana leaf extract (at 5% v/v concentration) was applied one week before transplanting of convert to days tomato cv Moneymaker seedlings into 20 cm diameter size pot containing 2 kg sterilized soil. Seeds of mustard and garlic were sown directly into the plastic pots on either side of the tomato seedlings. M. incognita was inoculated at the rate of 1000 and 2000 second-stage juveniles (J2) per pot one week after transplanting. A control without any nematode treatment was also maintained. The results revealed that combination of lantana leaf extract and tomato-mustard intercropping at both nematode inoculum levels proved to be the most effective treatment that reduced the soil and root population of the nematode. Application of lantana leaf extract alone and in combination at both inoculation levels showed superiority on tomato growth characteristics. Hence, this ecofriendly approach could be incorporated into integrated nematode management in tomato. However, further research is needed to evaluate their efficacies under field conditions.

“…Many factors may be attributed to these variation for instance physiological characteristics such as the permeability of nematode cuticles which may favor the penetration of certain compounds. 22 Biochemical differences between different nematode species may also have affected the degradation or detoxification of the compounds, therefore reducing activity of the compounds. 11 Mytech (P. lilacinus) and Vydate® had no significant difference in suppression of RKN and in crop biomass but both showed increased crop biomass compared to the other treatments.…”

Assessment of the Potential of Eco-Friendly Nematicides in the Management of Root-Knot Nematodes on French Beans in Kenya

Root-knot nematodes (RKN) (Meloidogyne spp) are a serious pest causing heavy economic losses in a wide range of agricultural crops. A trial was carried out to evaluate the effectiveness of various eco-friendly nematicides in the management of RKN affecting French bean. The field trial was carried out in two seasons with the following treatments; Rigel-G (salicylic acid), Phyto Protect (Sesame oil extract), Mytech (Paecilomyces lilacinus), Neemraj 0.3% (Azadirachtin), Vydate® (Oxamyl) as a positive control and an untreated control. Various rates; Rigel –G (2.5 ml/l), Phyto Protect (10 l/ha), Mytech (125 g/ha) Neemraj 0.3% (3L/ha) and Vydate® (6 l/ha) of treatments were administered and damage on plants was assessed based on galling indices, crop biomass and yield whereas nematode reproductive potential was assessed based on the J2 counts. There was no significant difference (P ≥ 0.05) in the nematode population densities and galling indices observed among the eco-friendly nematicides and the conventional nematicide (Vydate®). Eco-friendly nematicides had a significant (P ≤ 0.05) reduction of RKN J2 population densities compared to the negative control. The negative control had the highest mean of root-knot nematode densities (240 RKN/200 cc soil) and a galling index of 3.77 while Vydate and Neemraj had the lowest mean density (40 RKN/200 cc soil) in the first season. Similar results were observed in the second season with control having the highest RKN J2 population densities (285 RKN/200 cc soil) and a galling index of 3.89 and Vydate had the lowest (23 RKN/200 cc soil). The results of this study clearly indicate that eco-friendly nematicides can be fully adopted to suppress RKN in French beans as alternatives to conventional nematicides.
