Abstract Background Root-knot nematodes ( Meloidogyne spp.) are the most destructive agricultural pests, which parasitize thousands of different plant species in world. Using antagonistic bacteria can be a potential alternative to hazardous chemical nematicides. This study was conducted evaluate biocontrol activities isolated from vermicompost and earthworm against M. javanica infected tomato p...

Root-knot disease of mulberry is caused by the nematode Meloidogyne incognita. It has important economic implications for sericulture. The homeopathic medicines, Cina mother tincture (MT) and potentised Cina 200C, prepared from the flowering meristems of Artemisia nilagirica (Clarke) Pamp, were applied by foliar spray on mulberry (Morus alba L.) infected with M. incognita juveniles (J2). Pretre...

Meloidogyne enterolobii is widely considered to be an aggressive root-knot nematode species that is able to reproduce on root-knot nematode-resistant tomato and pepper cultivars. In greenhouse experiments, M. enterolobii isolates 1 and 2 from Switzerland were able to reproduce on tomato cultivars carrying the Mi-1 resistance gene as well as an N-carrying pepper cultivar. Reproduction factors (R...

Root-knot nematodes secrete effectors that manipulate their host plant cells so that the nematode can successfully establish feeding sites and complete its lifecycle. The root-knot nematode feeding structures, their "giant cells," undergo extensive cytoskeletal remodeling. Previous cytological studies have shown the cytoplasmic actin within the feeding sites looks diffuse. In an effort to study...

We tested a formulation composed of a mixture of Bidens pilosa var. radiata extract (BPE) and nematode-trapping fungi for its effects on Meloidogyne incognita. In earlier evaluations of the effects of plant extracts on the hyphal growth of 5 species of nematode-trapping fungi with different capture organs (traps), the growth of all species was slightly inhibited. However, an investigation on th...

Meloidogyne incognita can be effectively managed through biological control agents. The present study on the bio-intensive management of M. blackgram with bio-agents, viz. Bacillus marisflavi, altitudinis, subtilis, Trichoderma viride, Verticillium lecanii and Pseudomonas fluorescens as soil application was carried out under net house conditions at Department Nematology, Assam Agricultural Univ...

the chemical compound dl-?-amino-n-butyric acid (baba) has been introduced as a promoter of induction of resistance in plants against plant pathogens. in this study, promotion of induction of some such defense compounds as peroxidase and polyphenol oxidase enzymes through dl-?-amino-n-butyric acid application against root knot nematode (meloidogyne javanica) was investigated in cucumber. result...

Sweet potato is infested by root-knot and reinform nematodes. Root-knot nematode infestation in sweet potato is studied in detail. A number of resistant varieties are released in sweet potato from USA, Japan and China. A number of germplasm accessions and cultivars/ varieties were found resistant to the nematodes in Peru. Studies carried out by the authors indicated that sweet potato germplasm ...

Meloidogyne incognita, the root-knot nematode (RKN), a devastating plant parasitic nematode, causes considerable damage to agricultural crops worldwide. As sedentary root parasite, it alters root’s physiology and influences host’s phytohormonal signaling evade defense. The sustainable management of RKN remains challenging task. Hence, we made an attempt investigate nematicide activity Bacillus ...

a green house study was conducted to evaluate the comparative efficacy of pasteuria penetrans under the influence of organic amendments of four oil seed cakes namely azadirachta indica (locally known as neem), castor (ricinus communis), mustard (brassica campestris) and citrullus (citrullus colocynthis)on suppression of populations of meloidogyne incognita in chilli. oil seed cakes were applied...
