The time and condition of incubation of eggs were based on the method from Kong et al. Agric., Ain Shams Univ. Nitrite in the soil water phase is in equilibrium with nitrous acid {HNO2}, the non-ionized form of nitrite, and nitrous acid is known to be highly toxic to fungi and nematodes (Tenuta and Lazarovits 2002). Ammonia is generated from organic materials being decomposed by soil micro-organisms and is known to play an important role in the suppression of plant parasitic nematodes and fungi (Tenuta and Lazarovits 2002). Extension. Miller and Donahue (1990) reported that organic residues with C:N ratio of 20:1 has sufficient nitrogen to supply the plant growth. This will bring about biological suppression of parasitic nematodes in soil, hence promoting growth and development of the plants (Summers 2011). Control Root-Knot Nematode (Meloidogyne incognita) Disease Based on the Multi-E cacy Strategy Zhaoqian Fan 1,2, Yukun Qin 1,2,*, Song Liu 1,2, Ronge Xing 1,2, Huahua Yu 1,2 and Pengcheng Li 1,2,* 1 Key Laboratory of Experimental Marine Biology, Center for Ocean Mega-Science, Institute of Oceanology, Chinese Academy of Sciences, No. J Nematol 26:573–586, CAS  Trichoderma harzianum have been described as a promising biocontrol agent against Meloidogyne spp. Appl Soil Ecol 44:101–115, Oka Y, Shapira N, Fine P (2007) Control of root knot nematodes in organic farming system by organic amendments and soil solarization.

Application of NPK showed remarkable increase in eggplant yield; however the lowest percentage increase in eggplant yield was shown in T. harzianum treatment; in addition, all the combined treatments significantly improved yield production. 11; no 4; pp. Although NPK alone showed remarkable increase in eggplant yield, the data generally showed that other combined treatments gave better results in improving yield production than single treatments.

Download : Download high-res image (262KB) Download : Download full-size image; Fig. As already noted, the ammonia released from amendments is oxidized to nitrite in the first stage of nitrification. Olwe (2012) suggests that the fertilizer (NPK) or its component(s) have stimulatory effect on the plant leading to an enhancement of growth. The solarization is usual with the application of authorized products (usually dichloropropene). 2001). The research approach of using inorganic fertilizer NPK (containing nitrogen, phosphorus, and potassium) to control phytonematodes and maximize the crop yield has been reported by many authors (e.g. 1979; vol. The olive tree nurseries and the new plantations of olive groves on crops previous tobacco, cotton, sunflower… may have problems, being necessary to monitor the infections of Meloidogyne incognita. Fluensulfone is the active in-gredient of the new non-fumigant nematicide Nimitz. Losses of potatoes due to Meloidogyne species, mainly M. incognita and M. chitwoodi, are estimated at 25% or more (Mai et al., 1981). Moreover, numerous Bacillus species and strains especially Bacillus subtilus and Bacillus thuringiensis (Bt) have shown to suppress root-knot nematode and enhance plant growth. Oxamyl single treatment resulted in the greatest percentage reduction 78.7 and 71.2% in M. incognita egg masses and root galls respectively as compared to untreated control. Endoparasitic nematodes, such as Meloidogyne incognita, develop their cycle within the plant or host tree. During its development Meloidogyne spp. Plant Physiol Biochem 38:863–873. statement and Root-knot nematodes (Meloidogyne spp.) The percentage reduction in M. incognita, second stage juveniles (J2), in the soil was decreased by 81.2, 76.5, 70.1, 64.4, and 61.6% with single treatments of chicken manure, Oxamyl, T. harzianum, NPK, and Bt respectively as compared with untreated control. In vitro and screen house experiments were conducted to investigate the effectiveness of thirteen phytochemicals from Artemisia elegantissimiaand A. incisaon root knot nematode, Meloidogyne incognitain tomato (Lycopersicon esculentumL.) Therefore, environment-friendly management tactics have been developed for controlling plant parasitic nematodes and soilborne diseases (Noling and Becker 1994 and Oka 2010).
