Pseudomonads inogadzira huwandu hwakawanda hwemishonga inorwisa utachiona inosanganisira 2,4-diacetylphloroglucinol (DAPG), iyo ine yakafara-spectrum antagonistic maitiro ekurwisa phytopathogens. Rhizospheric ivhu samples dzakaunganidzwa kubva kuSolanaceous zvirimwa zvekuzviparadzanisa nefluorescent pseudomonads (FPs). Kunze kwe32 fluorescent bacterial isolates, 21 yakaratidza kupesana nekuita Ralstonia solanacearum (NAIMCC-B-01630) ine nzvimbo yepamusoro-soro yekudzivirira pa 38.33 mm. Pakati pavo, 11 mabhakitiriya akaparadzaniswa airatidzira kugadzirwa kweDAPG muKings 'B yepakati. Kugadzirwa kweDAPG kwakaonekwa neTLC uye kuverengerwa kuburikidza neHPLC ongororo. Uyezve, iyo bhakitiriya yekuzviparadzanisa OD13 yakaratidza yakakwira DAPG kugadzirwa. Uyezve, kuvapo kweDAPG-encoding phlD gene mukati mehukuru hwe629 bp uye 725 bp yakasimbiswa zvakare kuburikidza nekuwedzerwa. Aya mabhakitiriya akaparadzana aive egenera Pseudomonas sekusimbiswa nemorpho-physiological characterization uchishandisa VITEK 2 system. Iyo yakakwira DAPG-inogadzira bhakitiriya isolate yakaonekwa se Pseudomonas aeruginosa ne polyphasic nzira neGenBank kupinda nhamba OQ781265. Saka, iyo DAPG-inogadzira rhizospheric Pseudomonas strains inogona kushandiswa sebiocontrol agents kune bhakitiriya wilt. Nekudaro, kudzidza kwemumunda kwakakosha zvakanyanya isati yabudirira kushanda kwayo.
