“…Furthermore, [12] recorded the possibilit ies for bio logical control of powdery mildew (Sphaerotheca fuliginea, Erysiphe cichoracearum) and mildew (Pseudoperonospora cubensis) on cucumber by Enterobacter cloacae (J.) using the bio-agent Enterobacter cloacae sprays.…”

Evaluation the efficacy of bio-agents, application as foliar spray against vegetables foliar diseases incidence was carried out in open greenhouse conditions. The tested bio-agents were Trichoderma harzianum, T. Viride, Bacillus subtilis, Pseudomonas fluorescens and Saccharomyces cerevisiae were evaluated. The recorded foliar diseases, i.e. Powdery, Downy mildews of Cucumber, Cantaloupe and Pepper as well as Early, Late blights of Tomato were significantly reduced at all treat ments either alone or in co mb inations comparing with untreated plants. Application with either T. harzianum and B. subtilis showed significant reduction in diseases incidence comparing with the other applied bio-agents. The other bio-agent treatments, T. viride, P. fluorescens and S. cerevisiae recorded moderate reduction in this concern. On the light of the present study it could be suggested that the usage of bio-agents might be used as easily applied, safely and cost effective control methods against such foliar plant diseases.

“…For Enterobacter cloacae, application improved seed germination at the 3rd day (82% in treatment and 39% in control) and cucumber yield (6200 kg in treatment and 4550 kg in control). Both the single usage of E. cloacae (88%) or a mixture of E. cloacae strains and fungicides (96.6%) had control ability against CDM [115]. Enterobacter strain DP14 controlled CDM in two sequential years.…”

Cucumber downy mildew (CDM) is a destructive plant disease caused by the air-borne oomycete pathogen Pseudoperonospora cubensis. CDM causes severe yield reduction of cucumber and significant economic losses. Biocontrol is a promising method to control CDM with the advantage of being beneficial to sustainable agricultural development. However, until now, no reviews of biocontrol of CDM have been reported. The objective of this review is to more comprehensively understand the biocontrol of CDM. In this review, the biological characteristics of P. cubensis are introduced, and strategies for screening biocontrol agents to suppress CDM are recommended. Then the current biocontrol agents, including fungi such as Trichoderma and biocontrol bacteria such as Bacillus, which possess the ability to control CDM, and their control characteristics and ability against CDM are also summarized. The potential mechanisms by which these biocontrol agents prevent CDM are discussed. Finally, several suggestions for future research on the biocontrol of CDM are provided.

To identify new bacterial antagonists for cucurbit downy mildew (CDM) caused by Pseudoperonospora cubensis, 163 bacterial isolates were recovered from different microenvironments of field-grown cucumber plants. In the greenhouse, 19 representative isolates were applied to cucumber plants as a foliar spray (FS); 7 isolates achieved the efficacy over 60% against CDM, with 5 (DS22, HS10, DP14, HP4, and DS57) identified as Bacillus pumilus, B. licheniformis, Enterobacter sp., Bacillus sp., and Stenotrophomonas maltophilia, respectively. Strains DP14, DS22, and HS10 were assessed for their biocontrol effect on naturally occurring CDM in 2-year field trials (2010 and 2011), in which their overall efficacy relative to that of propamocarb was 106.25 to 117.17% with foliar spray plus root drench (FS+RD) but only 70.98 to 84.03% with FS. Coincidently, DP14 and HS10 applied as root drench (RD) alone also significantly reduced CDM. Under field conditions, DP14, DS22, and HS10 all successfully colonized cucumber leaves and the rhizosphere, and also significantly increased fruit yield by 37.60 to 51.03%, as well as nutrient levels. Taken together, Enterobacter sp. DP14, B. licheniformis HS10, and B. pumilus DS22 are plant-growth-promoting rhizobacteria effective in controlling CDM in the field, whose efficacy increased with FS+RD compared with FS alone.
