Effect of chitosan on root-knot nematode, Meloidogyne javanica
In our study two different chitosan with low and high molecular weight at different dilutions i.e. standard, 1:1, 1:2, 1:3, 1:4, 1:5 and 1:10 were evaluated against root-knot nematode, Meloidogyne javanica in vitro and in vivo under greenhouse conditions. In vitro results revealed that both chitosan with all used concentrations significantly reduced the egg hatching when compared to control. No...
متن کاملReduction of root-knot nematode, Meloidogyne javanica, and ozone mass transfer in soil treated with ozone.
Ozone gas (O₃) is a reactive oxidizing agent with biocidal properties. Because of the current phasing out of methyl bromide, investigations on the use of ozone gas as a soil-fumigant were conducted. Ozone gas was produced at a concentration of 1% in air by a conventional electrical discharge O₃ generator. Two O₃ dosages and three gas flow rates were tested on a sandy loam soil collected from a ...
متن کاملInheritance of resistance to the root-knot nematode Meloidogyne javanica in lettuce.
Resistance to the root-knot nematodes Meloidogyne spp. would be a valuable attribute of lettuce Lactuca sativa L. cultivars grown in tropical regions. The looseleaf lettuce 'Grand Rapids' is resistant to both M. incognita and M. javanica. Resistance to M. incognita has a high heritability, under the control of a single gene locus, in which the 'Grand Rapids' allele, responsible for resistance (...
متن کاملGlycoprotein Characterization of the Gelatinous Matrix in the Root-knot Nematode Meloidogyne javanica.
Proteinaceous components of freshly formed gelatinous matrix (GM) of the root-knot nematode Metoidogyne javanica were analyzed. Under reducing conditions, the prominent protein fragments had molecular weights of 26 to 66 kDa and 150 to >200 kDa, and most were glycosylated. Most of the fragments were digested by proteinase K, and fewer by trypsin. The lectins soybean agglutinin (SBA), Ulex europ...
متن کاملThe Nematicidal Effect of Camellia Seed Cake on Root-Knot Nematode Meloidogyne javanica of Banana
Suppression of root-knot nematodes is crucially important for maintaining the worldwide development of the banana industry. Growing concerns about human and environmental safety have led to the withdrawal of commonly used nematicides and soil fumigants, thus motivating the development of alternative nematode management strategies. In this study, Meloidogyne javanica was isolated, and the nemati...
