Influence of Potassium and Nitrogen Fertilization on Parasitism by the Root-knot Nematode Meloidogyne javanica.
The influence of various c oncentrations of K, nitrogen sources, and inoculation with root-knot nematode Meloidogyne javanica were evaluated in tomato plants. Increased potassium concentration increased top and root fresh weights of intact plants and fresh weights of excised roots. Nitrate-fertilized plants weighed more than plants receiving ammonium independent of the K level in the medium. Ne...
متن کاملEffect 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 کاملReaction of Pigeonpea Cultivars and Germplasm Accessions to the Root-knot Nematode, Meloidogyne javanica.
Meloidogyne javanica is an important nematode pest of pigeonpea. Thirty-four pigeonpea cultivars and 227 germplasm accessions were evaluated for resistance to M. javanica based on number of galls, egg masses, size of galls, and area of root covered with galls. Galls were not formed on 75% of the cultivars, and no egg masses were observed on the roots of four cultivars (UPAS 120, Pant A3, CO 1, ...
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...
