Soil application of DBCP (l,2-dibromo-3-chloropropane) and foliar applications of oxamyl (methyl N',N'-dimethyl-N-[(methylcarbamoyl)oxy]-l-thiooxamimidate) were compared for control of Tylenchulus semipenetrans in a grapefruit (Citrus paradisi) orchard, DBCP reduced nematode populations and increased fruit growth rate, fruit size at harvest, and yield compared to the untreated controls in the 2...
In this research, after optimization of sterilizing cyst and larvae of second stage of Heterodera schachtii, the possibility of using nematode on seedlings of sugar beet (Beta vulgaris L.) in in vitro condition was studied for developing larvae to cyst. For this purpose, non sterile cysts were extracted from infected soil and hatched into zinc chloride solution with concentration of 0.5gl-1. ...
Elucidating the biochemical basis of host-parasite relationships will be instrumental in the success of biologically based control in agriculture. This challenge is an ambitious one, but several central themes emerge regarding the roles of both parasiteand host-derived molecules. These include their contribution to nematode attraction, recognition, and reproduction as well as the response of pl...
Routine measures used to control the larval stages of non-statutory leafminer species in the United Kingdom rely largely on either the use of the braconid parasitoid Dacnusa sibirica Telenga and the eulophid wasp Diglyphus isaea Walker as, for example, in tomato crops, or on chemical insecticides for control in leafy salad and ornamental plants (Garthwaite and Thomas, 2001). The availability of...
Plant-parasitic nematode population densities were determined from 325 root and soil samples collected from vegetable growing areas in Pakistan. Yield losses associated with nematode presence were quantified on 19 vegetable crops during 2007 and 2009. The most abundant plant-parasitic nematodes detected, in order of decreasing frequency of infestation (percentage of samples), were Meloidogyne i...
Fruit wastes of apple (Malus pumila), banana (Musa paradisiaca), papaya (Carica papaya), pomegranate (Punica granatum) and sweet orange (Citrus sinesis) @ 20g/plant and the fungal biocontrol agent Paecilomyces lilacinus @ 2g (mycelium+spores)/plant, alone and in combination were evaluated for the management of reniform nematode, Rotylenchulus reniformis infecting chickpea under glasshouse condi...
The total phenol content of four common paddy cultivars Odisha namely Abhisek (R), Manik (MR), Bas-12 (S) and Lalat (HS) were studied under pot culture condition in the net house following CRD design different treatments using biofertilizer Azospirillum. brasilense alone or combinations against rice root-knot nematode Meloidogyne graminicola. objective work was to study quantitative changes phe...
Nematodes are roundworms that constitute the phylum Nematoda. Only a small fraction of nematode genera contains plant-parasitic or animal-parasitic species, while the majority of nematodes are free-living [1]. Heterodera glycines, the soybean cyst nematode, is a plant-parasitic nematode causing major damage to soybean production worldwide. Annual United States yield loss estimates due to H. gly...
On a survey during the period of 2006-2007 a number of tylenchids were found associated with Zea mays in Kashmir valley such as Pratylenchus sativus kaul, 1985, Aphelenchoides srinagrensis Kaul, 1985 and Tylenchorhynchus zeae Sethi and G. Swarp, 1968. These species were found to have morphometric variations probably due to habitat alteration from the originally described ones. As a part of the ...
biological control of root-knot nematode meloidogyne javanica by application of pseudomonas fluorescens cha0 was evaluated under greenhouse condition. results showed that p. fluorescens (109 cfuml-1) as shoot spray significantly reduced in no. of eggmass and egg per individual eggmass as comparison to control. application p. fluorescens as shoot spray induced systemic activation of peroxidase (...
