A pot experiment was carried out in the net house of Department of Nematology, OUAT, Bhubaneswar, Odisha, India during June to August, 2017 on the application of oilcakes (mustard cake and neem cake) and bio-agents (Trichoderma viride, Glomus fasciculatum, Rhizobium leguminosarum) each alone and in combination for the management of root knot nematode (Meloidogyne incognita) in green gram. Result of the experiment indicated that soil application of mustard or neem cake @ 50 g m-2 with AM fungus (Glomus fasciculatum) @ 5 g m-² and seed treatment of Rhizobium @ 25 g kg-1 of green gram seed declined the root knot nematode population, number of galls plant-1, number of eggmass plant-1and root knot index with corresponding increase of plant growth parameters and chlorophyll content in green gram plant as compared to other treatments and untreated check. But integration of mustard cake @ 50 g m-2 at 2 weeks prior to sowing with AM fungus @ 5 g m-2 at 10 days before sowing and seed treatment of Rhizobium @ 25 g kg-1 green gram seed exhibited the lowest M. incognita population 200 cc soil-1 (153.33 J2), number of galls plant-1 (7.0), number of eggmass plant-1 (2.0) and root knot index (2.0) reflecting enhancement of plant growth parameters, number of pods (206.67%), number of nodules (691.17%) over untreated check. This integrated management module also recorded maximum increase in the availability of NPK content in soil and chlorophyll content as compared to other treatments.

Crop Sequence

With a surface area of 37 000 ha and an annual yield of 3 × 106 t, the south-east of Spain, predominantly the coast of Almeria, is the largest horticultural growing area under protected cultivation in Europe. A survey on perception of the impact of root-knot nematodes on vegetable production was carried out in this area by face-to-face interviews with 120 farm advisors. The survey was designed to evaluate opinions about prevalence and severity of root-knot nematode-induced diseases, percentage of infested area and effectiveness of root-knot nematode control methods. According to the answers, 17.7% of the fields were infested with root-knot nematode and 18.8% of the cultivable area within each site showed root-knot nematode disease symptoms, which came to 2.0% of the total area used to grow vegetables in the region. Average yield loss was estimated at about 30.8% of total vegetable production, and 38.1% of the farm advisors considered that root-knot nematode infections had increased over the last 5 years. Most farm advisors (78.3%) stated that the most commonly used control method was chemical soil fumigation. Non-fumigant nematicides were cited by 59.8% of them, grafting and resistant cultivars by 42.3%, soil solarisation 38.1%, plant extracts 14.4% and biofumigation 6.2%. The majority of farm advisors considered the application of fumigant nematicides combined with soil solarisation, and grafting onto resistant rootstocks as the most effective methods of root-knot nematode control. In addition to the interviews, plant and soil samples were taken from plastic greenhouses throughout the region to determine species of root-knot nematode present. Meloidogyne javanica was the most prevalent species followed by M. incognita and M. arenaria, but species distribution was linked to the predominating crop sequence in each area, since M. javanica occurred less frequently when sweet pepper rather than tomato appeared in the crop sequence.

Integrated control of  ginger wilt disease  (Ralstonia solanacearum Smith) and root knot nematodes (Meloidogyne spp.). The purpose of this research was to obtain  reasonable integrated control ginger wilt disease. The research was conducted in endemic area of ginger wilt disease at Biaung village, Penebel Regency during April, 2003 to Januari, 2004. Randomized block design (RAK) with three replication and 11 treatments was used in this experiment. Research result appears that ginger wilt diseases can be controlled by integrated control using seed treatment with soaked method in urea-polymer + Bacillus sp. (2g/l water for two hours and then for planting treatment with vermi-compost (150g/plant) + fire-wood ash (50g/plant) + Mycorrhiza (100 g/plant). Root knot nematode (Meloidogyne spp.) was effective controlled by dolomit (5g/plant) + seed-treatment with bactericide (Agrimicin 500 ppm) +  vermi-compost (150 g/plant).

Present Trial

Cucumber (Cucumis sativus L.) is a high nutritious and mineral-rich vegetable, which occupies a prominent place as a salad and vegeta-ble. It is being used in many ways in the daily diet of humans and widely cultivated worldwide. The decrease of agricultural land, ad-verse environmental conditions and continuous increase of popula-tion, the demand of nutritious food is a matter of great concern to the world. Protected cultivation is a very effective tool to solve this problem because in this cultivation the productivity of crops is very high as compared to open field conditions. High value crops suc-cessfully grown in protected cultivation, specially vegetables (cu-cumber, tomato, Capsicum etc.) which are highly susceptible to the numerous pests and pathogens, including phyto-parasitic nema-todes (specially root-knot nematode, Meloidogyne spp.). With this view, present trial was taken to estimate the avoidable losses caused by Meloidogyne incognita infecting cucumber in poly-house situated on farmer’s field with the application of phorate at 2 kg a.i. ha-1 over check. Results exhibited that application of chemical treatment significantly reduced number of galls per 5 g roots, egg masses per 5 g roots, eggs & juveniles per egg mass and final nema-tode population 79.03, 81.10, 30.91 and 56.54%, respectively. Avoidable yield losses were recorded to the tune of 66.84% on cu-cumber by M. incognita in poly-house.

In Coastal Plain soils of the southeastern United States, the root-knot nematode (RKN) Meloidogyne incognita race 3 causes significant yield loss in corn. Impact of abamectin + thiamethoxam and clothianidin + Bacillus firmus I-1582 nematicide seed treatments along with terbufos granular nematicide on RKN reproduction, plant populations, plant growth, and yield was assessed at two Alabama sites. Thiamethoxam and clothianidin insecticide seed treatments were included as controls. A factorial arranged as split-split plot with year as the main plot, seed treatment as the split plot, and granular nematicide as the split-split-plot treatment was used. Lower plant populations were noted for terbufos-treated corn at one study site. Reduced RKN reproduction was observed with terbufos granular nematicide at both study sites. Fresh seedling weights and yields were usually higher for the terbufos- than non-terbufos-treated corn. At both sites, both nematicide seed treatments and their insecticide seed treatment counterparts had similar plant populations, RKN reproduction rate, and fresh seedling weights. Yield differences were noted at both locations between abamectin + thiamethoxam and thiamethoxam but not clothianidin + Bacillus firmus I-1582 and clothianidin. With mean yield gains up to 13.5%, terbufos was superior to both of the nematicide seed treatments for managing RKN and protecting corn yields. Accepted for publication 19 October 2015.

<p>Root-knot nematodes (<em>Meloidogyne</em> spp.), play a major role in loss of agricultural production<strong>. </strong>Natural substances<strong>,</strong> such as salicylic acid (SA) could possibly be involved in inducing host plant resistance against nematodes. The present study is concerned with exploring the effects of varying concentrations of SA as seed priming and soil drench on tomato growth parameters and the reproduction of the root-knot nematode <em>Meloidogyne javanica</em>. SA at 50 μM concentration caused only 2% of juvenile mortality under in vitro conditions. SA applied as 50 μM seed treatment caused 95% and, as a soil drench, 78% reduction in the number of egg masses that formed on tomato plants. The numbers of galls were reduced to a lesser extent. Final nematode density per gram of soil was reduced to less than 1 by the 50 μM SA seed treatment, and in other treatments decreased by between 70 and 88% compared with control plants. Our results indicate SA has potential to lower root knot nematode reproduction in tomato, and seed priming is a fairly easy method to work with.</p>

Root-knot nematode, Meloidogyne incognita is an economically important plant-parasitic nematode of vegetable crops grown under open as well as protected cultivation. Use of resistant cultivar is an important measure for managing root-knot nematode as compared to the other management strategies. Despite the potential importance of this nematode, sources of resistance to M. incognita are not yet available for breeding purposes. Present studies were conducted to evaluate the resistant reaction of crop genotype (cucumber japanes long green, tomato shu, cherry tomato P. cherry tomato-1, bitter gourd pusa aushadhi and capsicum yalo wonder) against M. incognita under polyhouse conditions (2018-20). Sixty days after sowing, observations were recorded on number of galls/plant and final nematode population. All the crop genotypes of vegetables were showed varying degree of response against M. incognita. Out of five crop genotypes of vegetables, four (cucumber japanes long green, tomato shu, cherry tomato P. cherry tomato-1 and bitter gourd Pusa aushadhi) were susceptible/highly susceptible while capsicum yalo wonder showed moderately resistant reaction against M. incognita in both the years (2018-2020) and this genotype can be used as a source of resistance.

Abstract Relative efficacy of various approaches to managing Meloidogyne incognita and soil borne fungus, Fusarium oxysporum f. sp. cucumerinum in cucumber for two seasons was tested under protected cultivation. Several management practices adopted such as chemicals (fumigant, non-fumigant, and fungicide), organic amendments (Neem cake, leaves and oil, soil and seed treatment), and biocontrol agents (the egg-parasitic fungus, Purpureocillium lilacinum), all practices combine for the management of disease. Eleven treatments with untreated control in a randomized block design. Two significant parameters were measured: plant growth parameter (plant height, dry root weight and yield) and disease parameters (galls/plant, final nematode population, egg masses/plant and fungal incidence). All treatments significantly improved plant growth parameters and reduced nematode reproduction as compared to untreated check. The integration of formalin and neem oil seed treatment favor the low root galling index compared to all other treatments in both the seasons. Integration of formalin and neem oil seed treatment reduced nematode population and fungus incidence and increased the yield of cucumber during both the seasons.

Pot experiment was conducted to evaluate the efficacy of two formulations (talc formulation and vermi formulation) of four bacterial nematode biocontrol agents viz., Bacillus subtilis, Bacillus pumilus, Bacillus megaterium and Pseudomonus flourescens as seed treatment against root knot nematode, Meloidogyne incognita on tomato. All the bioagents were tries at 10 and 20g / kg of seed. The experiment was terminated at 60 days after sowing the seed. The results revealed that all the treatments significantly increased the plant growth parameters and reduced the nematode multiplication over untreated control. However, maximum plant growth parameters and minimum galls per root system, eggmasses per root system, eggs per egg masses and final nematode population was recorded when seeds of tomato (var. Pusa Ruby) was treated with talc formulation of Pseudomonus flourescens @20g/kg followed by seed treatment with vermi formulation of Bacillus subtilis @ 20g/kg of seed.
