Root-Knot Nematode, Meloidogyne incognita has emerged as one of the serious threats to vegetable production throughout the world due to its adaptable nature, wide host range, and ability to cause huge losses. The losses caused by a root-knot nematode, M. incognita may vary from 16 to 80%. The various diagnostic symptoms are stunted growth, yellowing, root gall formation of the vegetable crop. A survey was conducted in Sitapur district and it was revealed that root-knot nematode is one of the serious threats in pointed gourd production, approximately 20 to 50% yield was recorded and it was observed that it is one of the limiting factors and will be a serious threat. The diagnostic symptoms degree depends upon several factors such as time of infection, variety, a load of inoculums, and abiotic factors such as soil type, texture, moisture, pH, carbon content, etc. Farmers were advised to use eco-friendly approaches such as removal of weeds, summer plowing, use of organic amendments and resistant cultivar may reduce the nematode population.

Cucurbitaceae Family

Pointed gourd belongs to cucurbitaceae family and is extensively cultivated in eastern Uttar Pradesh (10000 Hectares), Bihar (14000 hectares), West Bengal, Assam, Orissa, Madhya Pradesh, Maharashtra and Gujrat. Its plants are perennial in nature and can survive for several years even if left uncared. This crop occupies large area of land in India. The system of cultivation varies from region to region such as trained on pandals or ardours especially during the rainy season in southern and western India. However, it is most susceptible to root-knot nematode, Meloidogyne incognita, the population level or density of root-knot nematodes were found in the range of 15–100 per cent of the root and soil samples. This nematode induces severe damage to pointed gourd on coarse-textured sandy soils, particularly during droughts stress. Crop failure is noticed at earlier stage of vines. In view of fact it is necessary to evolve the integrated strategies for management of root-knot nematode in this viny crop.

ABSTRACT: Root-knot nematodes, Meloidogyne spp., are among the most important parasites of the lettuce crop. Managing these organisms is difficult due to limitations in genetic (use of resistant cultivars) and chemical control. Thus, new practices should be sought to reduce their reproduction. The present study aimed to evaluate the application of organic amendments in the control of Meloidogyne incognita in lettuce. At first, tomato plants were inoculated to establish an initial population in the soil. After 60 days, the aerial part was discarded, and the lettuce seedlings were transplanted into pots. Two days after transplanting, the treatments bokashi, crambe cake, whey protein, cottonseed composted and shredded wood chip composted were applied at 20 g or 20 mL per pot. Water was applied as control treatment. After 70 days, bokashi and crambe meal reduced the number of eggs/g of root and promoted plant growth. Results obtained with whey protein, cottonseed meal and composted shredded wood chip did not differ from those obtained with the control treatment. Bokashi and crambe cake are effective in the M. incognita control under controlled conditions.

Treatment Application

A field experiment was conducted in two consecutive years to find out the efficacy of poultry refuse (PR), mustard oilcake (MOC), and Furadan 5G for the management of root-knot disease (Meloidogyne incognita) of tomato. Soil was treated with PR @ 3 and 5 t/ha, MOC @ 0.3 and 0.6 t/ha 3 weeks before transplanting and Furadan 5G @ 40 kg/ha on the day of transplanting of tomato seedlings. PR @ 3 t/ha and MOC @0.3 t/ha were applied alone and also mixed with Furadan 5G @ 20 kg/ha. The soils of the experimental plots were inoculated with chopped severely galled (M incognita) roots of tomato at the time of treatment application. In both the years, considerable reduction in rootknot disease and increase in plant growth and fruit yield were achieved with different treatments with two organic materials applied alone or mixed with Furadan 5G. The most effective treatment was PR @ 3 t/ha + Furadan 5G @ 20 kg/ha followed by PR alone @ 5 t/ha. Efficacy of PR @ 3 t/ha and MOC @ 0.6 1/ha were also appreciable. In first year and second year, gall index values were 6.50 and 6.27 under control, respectively. The severity was reduced to 2.27-4.00 in first year and 1.73-4.07 in second year due to application of the four treatments. On the other hand, fruit yield under control was 50.9 t/ha at first year and 47.6 t/ha in second year. The highly effective four treatments increased fruit yield to 71.1-82.5 t/ha in first year and 60.8-82.0 t/ha in second year. The fruit yield of tomato was directly and linearly correlated with gall indices in tomato gall. Based on findings of the study PR @ 3 t/ha + Furadan @20 kg/ha and PR alone @ 5 t/ha were noted as effective treatment to manage root-knot disease of tomato.

Abstract Background Organic amendments are well known for influencing soil nematode community structure, diversities, and activities. Most of the previous studies focused on effects of organic amendments on plant-parasitic nematodes, but only a few investigated the effect of combination of biocontrol agents and organic amendments on soil nematodes. Main body Different organic amendments (neem cake, poultry manure, and neem leaves) were combined with the predatory nematode, Fictor composticola, for the control of root-knot nematode, Meloidogyne incognita, in cucumber. Organic amendments were mixed in pots containing 1 kg soil, 15 days before sowing. Cucumber (cv. CCH-1) plants grown in these pots were inoculated by 2000 J2 of M. incognita and 400 F. composticola per pot, after 1 week of germination. Fictor composticola in combination with chicken manure + neem cake + neem leaves was found the best mixture for reducing the number of galls, egg masses, and final root-knot nematode population. The predator’s population reached the maximum in this treatment. All combinations of organic amendments in the presence of F. composticola were found significantly superior over inoculated check in reducing nematode’s population and in improving plant growth over the un-inoculated check. Conclusions Data indicated the suitability of using the predatory nematode, F. composticola, and organic amendments for potential use in sustainable nematode management strategies.

AbstractThis study was conducted to evaluate the effects of three fungal species, Trichoderma harzianum (Th), T. viride (Tv), and T. vierns (Tvi), and ground seeds of fennel (Foeniculum vierns) and caraway (Carum carvi), and powdered leaves of basil (Ocimum basilicum) as soil amendments against the root-knot nematode, Meloidogyne incognita on pea root, Pisum sativum under screen house conditions. The treatments were compared to a nematicide, carbofuran 10G, and untreated check. The tested materials significantly (P ≤ 0.05) reduced M. incognita on pea as indicated by the numbers of galls, egg masses, and J2 per root system in pots, either as single or combined treatments. The combined treatments caused higher average total percentages of nematode reduction than those achieved by single ones. The single treatments recorded the averages total percentages of nematode reduction ranged from 72.4 to 82.0%. Basil waste as single was superior in reducing nematode numbers of J2 and egg masses in root system per plant, as it achieved the highest average total percentages of nematode reduction (77.9%) than 73. 9 and 72.4% caused by fennel and caraway, respectively. In combined treatments, the average total percentages of nematode reduction ranged from 72.4 to 86.4%. Basil + (Th) caused the highest reduction (86.4%), followed by caraway+Tvi (86.3%) and caraway+Th (86.2%). The nematicide, carbofuran was as effective as most as the treatments in reducing nematode parameters. Also, the treatments highly increased growth and yield criteria of pea infected with M. incognita as indicated by shoot length and fresh and dry weights and root fresh weight, number and fresh and dry weights of pods.
