Macrophomina phaseolina (Tassi) Goid. geniş konukçu aralığına sahip toprak kökenli bir hastalık olup mücadelesi oldukça zordur. Bundan dolayı, çalışmamızda 2021 yılında Konya’nın Çumra ilçesinden alınan fasulye bitkilerinin farklı aksamlarından (çiçek, gövde, kök ve yaprak) topraktan elde edilen toplam 71 bakterinin hastalığa karşı in vitro etkinliklerinin belirlenmesi amaçlanmıştır.

ABSTRACT Lafoensia pacari represents an alternative to control phytopathogens and common bean (Phaseolus vulgaris L.) diseases. This study aimed investigate the chemical composition of L. phenolics-containing extract obtained from leaves assess its in vitro vivo inhibitory activity against Curtobacterium flaccumfaciens pv. flaccumfaciens, Xanthomonas axonopodis phaseoli, fuscans subsp. fuscans,...

Here, we describe a novel mycovirus, tentatively designated as "Botryosphaeria dothidea mitovirus 3" (BdMV3), isolated from Botryosphaeria strain FJ, which causes pear ring rot disease in Fujian Province, China. The complete genome nucleotide sequence of BdMV3 is 2538 nt length and contains single 2070-nt open reading frame (ORF) encoding putative RNA-dependent RNA polymerase (RdRp) 689 amino a...

In the current perusal, 12 isolates of Pseudomonas were segregated by rhizospheric soil chickpea (Cicer arietinum) Madhya Pradesh, India. Isolated test organisms characterized morphologically, biochemically and 16S rRNA gene sequencing. Out 12, one isolate designated as P4 was identified aeruginosa through sequencing, which revealed 100% homology with strains DSM 50071 NBRC 12689. The phylogene...

in vitro antifungal activity of silver nanoparticles, at concentrations of 6, 8, 10, 12, 14 and 16 ppm, was studied on five phytopathogenic fungi, and a biocontrol agent. then effect of silver nanoparticle at 6 ppm (optimum concentration) was evaluated on macrophomina phaseolina in greenhouse. for in vitro experiment, the fungal isolates were grown on potato dextrose agar medium amended with si...
