A study was conducted to assess the effect of individual and combined application of Trichoderma viride and other organic amendments on plant growth and nematode multiplication parameters in comparison with chemical, carbofuran 3G and untreated check for management of root-knot nematodes under polyhouse in Bihar. Maximum improvement in the plant growth parameters was observed with combined application of T. viride @ 10 g/pot + neem cake @ 100 g/pot. Carbofuran 3G @ 2 kg a.i./ha was found most effective in controlling root knot nematodes. T. viride @ 10 g/pot + neem cake @ 100 g/pot increased crop yield by 77 %, compared to 60 % with carbofuran. Neem cake had increased the efficiency of the biocontrol agent, which might be partially due to reduction in nematode population by the action of toxicity of fungal bio agents and partly to the fact that neem cake additive served as manure for management of M. incognita.
以比哈尔邦为例，研究了单独施用和联合施用绿色木霉及其他有机改良剂对植物生长和线虫繁殖参数的影响，并与化学药剂、呋糠胺3G和未经处理的防治根结线虫进行了比较。10 g/盆绿苔+ 100 g/盆印楝饼对植株生长参数的改善最大。在防治根结线虫方面，2 kg a.i./ha的呋喃3G最有效。10克/罐的翠素+ 100克/罐的印楝饼可使作物产量提高77%，而使用呋喃可提高60%。印楝饼能提高生物防治药剂的防治效果，其原因可能是由于真菌生物药剂的毒性作用减少了线虫的数量，也可能是印楝饼添加剂作为粪肥用于管理隐僵菌。

A trial was conducted under green house condition to study the efficacy of some chemicals as soil fumigation and soil application on plant growth characters and reproduction of M. incognita infecting bell pepper. In this study, chemicals viz. metham sodium at 20 ml/m2, 30 ml/m2, 40 ml/m2, fluensulfone at 5 g/m2, 10 g/m2, 15 g/m2 and carbofuran at 20 g/m2 were applied and suitable control was also maintained for comparison. Observations on plant growth characters (shoot and root length, shoot and root weight) and nematode reproduction factors (number of galls per 5g root, number of egg masses per 5g root, nematode population/200 cc soil) and yield kg/plant were recorded. Results showed that metham sodium @ 40ml/m2 was best treatment to improve the plant growth characters, yield and reducing nematode reproduction on bell pepper.

Cultivated fenugreek Trigonella corniculata L, also known as kasuri methi or nagauri paan is a popular spice crop and widely grown in the state of Rajasthan, India. Galls and root-knot nematodes were observed on the roots of T. corniculata collected from Naguar district and its surrounding areas in the state of Rajasthan. The nematode DNA isolated from the sample was subjected to PCR by using species-specific primers for the common root-knot nematode species. Molecular identification confirmed the infestation of Meloidogyne enterolobii on T. corniculata. This is the first report of M. enterolobii infestation on T. corniculata from India.

Safety issues on the residual effect of pesticides and their metabolites on fruits and vegetables are of utmost importance. Synthetic pesticides remain in fruit and vegetables after harvest causing great health hazards to the consumers. Field studies were conducted on the evaluation of Leucaena leucocephala leaves as an alternative to the use of synthetic nematicide, while possible residues of carbofuran in tomato fruits were also analysed. Acetone, methanol and petroleum ether fractions of the leaves of L. leucocephala were applied at 200 mg/mL in variants of 100 mL, 150 mL and 200 mLto a naturally nematode infested field. Comparison was made with carbofuran a synthetic nematicide. Samples of tomato fruits from carbofuran treated and untreated beds were extracted with ethyl acetate for residual pesticide analysis to ascertain the exceedance of the maximum residue limit (MRL). Results revealed that pesticide residue was significantly (P=0.05) higher in plots treated with carbofuran compared with standard MRL for carbofuran in tomatoes. Crude extracts of L. leucocephala were as effective as carbofuran, while the fraction was however significantly better in producing more numbers of fruits and reduced nematode population in root and soil.

Root-knot nematodes, Meloidogyne spp. are one of the most important pests of tomato crop. Among the promising bio-control agents of plant parasitic nematodes, the bacterial parasite-Pasteuria penetrans has been investigated in detail and found to hold potential for the management of Meloidogyne spp. An experiment was carried out underscreen house conditions of Department of Nematology of CCS Haryana Agricultural University, Hisar, to study the effect of organic amendments (neem cake, mustard cake, castor cake and farmyard mannure) on the life cycle development of P. penetrans on M. javanica infecting tomato. All life cycle stages of bacterium viz., microcolony, thallus, quartets, diads, immature spore and mature spore were observed and nematode viz., parasitic J2, spike tail stage, immature and mature female were observed and compared for all the organic amendments. The result revealed that the life cycle of P. penetrans on root-knot nematode was completed in all the organic amendments but, the life cycle was well synchronised with root-knot nematode when it was integrated with mustard cake.There was slight delay in life cycle of bacterium where castor cake, neem cake and FYM were applied. However, both nematode and bacteriumcompleted their life cycle in all the organic amendments.
