an ability of the fluorescent pseudomonad bacteria is to secrete such secondary metabolites as hydrogen cyanide, protease, salicylic acid as well as siderophore which prevent the growth of soil-habitant pathogens. tests were done for evaluating the materials produced by the said bacteria. in the tests' cultures, p. aeruginosa strains 7nsk2, utpf92, and utpf86 produced the most hydrogen cya...

Abstract Passion fruit (Passiflora spp.) yield is limited by several factors, including soil pathogens, such as Rotylenchulus reniformis (the reniform nematode) and Meloidogyne incognita Southern root-knot nematode). Understanding the behavior of different cultivars, within species passion could be important asset to search for sources resistance, therefore effective management phytonematodes. ...

Pasteuria penetrans is a mycelial, endospore-forming, bacterial parasite that has shown great potential as a biological control agent of root-knot nematodes. Considerable progress has been made during the last 10 years in understanding its biology and importance as an agent capable of effectively suppressing root-knot nematodes in field soil. The objective of this review is to summarize the cur...

Cucumis melo var. texanus, a wild melon commonly found in the southern United States and two accessions, Burleson Co. and MX 1230, expressed resistance to Meloidogyne incognita in preliminary experiments. To characterize the mechanism of resistance, we evaluated root penetration, post-penetration development, reproduction, and emigration of M. incognita on these two accessions of C. melo var. t...

Criconemoides xenoplax and Meloidogyne incognita were the nematode species most frequently associated with peach in North Carolina. Other nematodes often found in high numbers on that crop were Pratylenehus vulnus, Helicotylenchus spp., Trichodorus christiei, Xiphinema amerieanum and Tylenchorhynchus claytoni. P. vulnus and P. penetrans reproduced well on rootstocks of 21 peach cultivars tested...

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...

azospirillum is a well-studied genus of plant growth-promoting bacteria. phytohormone production by pgpr is considered as one of the effective factor to increase the tomato yield significantly. in order to study the effect of azospirillum inoculant on on growth characteristics and yields of tomato, three strain of azospirillum were isolated, identified, and purified from tehran suburb soils. to...
