The role of Pseudomonas fluorescens in the process of Rhizoctonia solani growth inhibition

2014

The aim of conducted research was to determine influence of metabolites produced by Pseudomonas fluorescens on the growth of 4 phytopathogenic strains of Rhizoctonia solani marked R1, R2, R3 and R4 which infect sugar beetroot. The antagonistic properties were assessed with the culture-plate method on PDA medium for P. fluorescens cultured for 4, 6 8, 10 and 24 hours at 25 o C for 5 days. The fungistatic activity of P. fluorescens was determined against the growth rate index and the rate of mycelial growth inhibition. Obtained results prove, that Rhizoctonia spp. strains were both sensitive and resistant to metabolites produced by P. fluorescens. The highest inhibition of the linear growth o…

Effect of analogues of plant growth regulators on in vitro growth of eukaryotic plant pathogens

2004

FGA (furfurylamine; 1,2,3,4 tetra-O-acetyl-β-d-glucose; adipic acid monoethyl ester), a chemical mixture of three analogues of plant growth regulators that increases the protection of tomato plants against phytopathogens, was demonstrated to have direct antimicrobial activity. It reduced the growth in vitro of the filamentous fungi Alternaria solani and Botrytis cinerea, and the oomycetes Phytophthora capsici and Phytophthora citrophthora (ED50 0·18–0·26% w/v, depending on species). The components of this mixture were also active against these phytopathogens, but sensitivity to the compounds was different for each pathogen. Adipic acid monoethyl ester (E) showed the highest and widest range…

Activity of bacteria strains originaited from sewage sludge against some soil fungi

2004

Abstract The potential biological activity of three bacterial strains against the four phytopathogens was examined. The bacterial strains were originated from sewage sludge water extract and from the humic acid solution obtained from the sewage sludge. The fresh bacteria cultures and filtered culture broth were used. The noncoated sugar beet seeds were coated by soaking for 15 min in the liquid culture of bacteria, then they were sown in the sterilized soil inoculated by one of the following types of soil fungus: Aphanomyces cochlioides L3, Phoma betas PH8, Pythium irregulare PIR4, Rhizoctonia solani Z10-2. The test proved that Bacillus amytoliquefaciens O1 / O3 and Flaviomonas oryzihabitan…

Investigation of fungicidal activity of 3-piperazine-bis(benzoxaborole) and its boronic acid analogue

2014

3-Piperazine-bis(benzoxaborole) and its bis(phenylboronic acid) analogue were investigated in terms of their fungicidal activity. The study was carried out against five filamentous fungi: Aspergillus terreus, Fusarium dimerum, Fusarium solani, Penicillium ochrochloron and Aspergillus niger. 3-Piperazine-bis(benzoxaborole) revealed higher inhibitory activity towards the examined strains than standard antibiotic (amphotericin B), whereas bis(phenylboronic acid) proved to be inactive. The study unequivocally showed that the presence of the heterocyclic benzoxaborole system is essential for antifungal action of the examined compounds. Copyright © 2014 John Wiley & Sons, Ltd.

Three novel synthetic amides of adipic acid protect Capsicum anuum plants against the necrotrophic pathogen Alternaria solani

2003

Three novel amides of adipic acid, 5-carbamoil ethyl pentanoate (N1), 5-(2-furfurylmethylcarbamoil) ethyl pentanoate (N2) and 5-(3-aminopropylcarbamoil) ethyl pentanoate (N3) were synthesized and their resistance-inducing activity was studied on pepper (Capsicum annuum) plants. Treatment with low doses of each amide protected pepper plants against the pathogen Alternaria solani, N1 being the most effective. Although their mode of action is still unknown, prechallenge studies demonstrated the induction of the phenylpropanoid pathway and an antisenescence effect. These effects were previously shown for other mixtures and derivatives of adipic acid. These new chemicals showed no antimicrobial …
