“…Brown spot is a complex disease because of the biology and ecological ability of the causative agent [5]. S. vesicarium can colonize pear leaf and dead tissues of herbaceous plants on the ground [6]. It is known that the incidence of brown spot disease is higher in pear orchards with a lawn of herbaceous plants than in bare soils [3].…”

Potential Application of Propolis Extracts to Control the Growth of Stemphylium vesicarium in “Rocha” Pear

Stemphylium vesicarium (Wallr.) E. G. Simmons is the pathogen responsible of brown spot disease in pear and has become one of the main concerns for European pear producers. In Portugal, S. vesicarium is responsible for significant yield reduction and economic losses in “Rocha” pear (Pyrus communis L. cv Rocha) production. Considering the antimicrobial potential of propolis, the high incidence of brown spot in pears and the emergence of fungicides resistance in S. vesicarium, this study aimed to evaluate the potential of Portuguese propolis as an alternative strategy to control brown spot disease in “Rocha” pear. In vitro assays showed that propolis extracts were able to inhibit up to 90% the S. vesicarium mycelial growth. In vivo assays in artificially wounded and inoculated “Rocha” pears showed that, compared to the control, the disease incidence decreased up to 25% and the lesions diameter up to 57%, in fruits treated with propolis. Moreover, propolis seems to be more efficient in reducing the disease incidence when applied after pathogen inoculation (curative assay) than when applied before pathogen inoculation (prophylactic assay). Thus, the results suggest that propolis extracts have potential to be applied as part of an integrated approach for the control of brown spot of pear.

“…Due to the costly production of AMPs at the moment, large scale field studies and applications of AMPs are rare ( Table 1 ). The synthetic antimicrobial peptide BP15 showed great potential in controlling brown spot disease of pear, showing a disease reduction of about 42%-60% in the serial trials ( Puig et al., 2015 ). Hayouka et al., 2017 synthesized 20-amino-acid-length peptides chain mixture with only two kinds of amino acids with relatively low cost.…”

Pathogen infection is one of the major causes of yield loss in the crop field. The rapid increase of antimicrobial resistance in plant pathogens has urged researchers to develop both new pesticides and management strategies for plant protection. The antimicrobial peptides (AMPs) showed potential on eliminating plant pathogenic fungi and bacteria. Here, we first summarize several overlooked advantages and merits of AMPs, which includes the steep dose-response relations, fast killing ability, broad synergism, slow resistance selection. We then discuss the possible application of AMPs for plant protection with above merits, and highlight how AMPs can be incorporated into a more efficient integrated management system that both increases the crop yield and reduce resistance evolution of pathogens.

“…A library of AMPs named CECMEL11 has been developed composed of cecropin A‐melittin hybrid undecapeptides (Badosa et al ., ). Some of their members showed strong activity against plant pathogenic bacteria and fungi, and were effective in controlled environment tests in the greenhouse against plant diseases of apple, pear and pepper (Badosa et al ., , ; Puig et al ., ) and also in the field (Puig et al ., ).…”

Control of rubus stunt and stolbur diseases in Madagascar periwinkle with mycorrhizae and a synthetic antibacterial peptide

Three experimental treatments consisting of inoculation with an arbuscular mycorrhizal fungus, application of a synthetic antimicrobial peptide or application of a resistance inducer, were evaluated in Madagascar periwinkle as control methods for rubus stunt and stolbur diseases caused by 'Candidatus Phytoplasma rubi' and 'Candidatus Phytoplasma solani', respectively. Two experiments were conducted under controlled environment conditions. In the first experiment, 4 months after graft-inoculating the phytoplasmas, the root colonization achieved by Rhizophagus irregularis significantly reduced both disease symptoms and the frequency of detection of the pathogens by real-time PCR. In the second experiment, the antimicrobial peptide BP100 totally prevented disease symptoms, despite the molecular detection of the phytoplasmas in 75% and 50% of the plants inoculated with 'Ca. Phytoplasma rubi' and 'Ca. Phytoplasma solani', respectively, and was more effective than benzothiadiazole (BTH) at increasing resistance against the pathogenic infections. A potential combination of early mycorrhizal inoculation and BP100 antimicrobial peptide application is envisaged as a future control strategy for phytoplasma diseases.
