Three damaging soybean diseases, Sclerotinia stem rot caused by a fungus Sclerotinia sclerotiorum (Lid.) de Bary, Phytophthora root rot caused by a fungus Phytophthora sojae, and soybean cyst nematode (Heterodera glycines Ichinohe), are destructive to soybean growth and yield and cause huge economic losses. Biocontrol is an effective way to control soybean diseases with the advantage of being environmentally friendly and sustainable. To date, few reviews have reported the control of these three soybean diseases through biocontrol measures. In this review, the biological characteristics of the three pathogens and the incidence features of the three soybean diseases were first introduced. Then, biocontrol agents containing fungi and bacteria capable of controlling the three diseases, as well as their control abilities, were emphasized, followed by their mechanisms of biocontrol action. Bacillus and Streptomyces were found to possess the ability to control all three soybean diseases under greenhouse or field conditions. Finally, suggestions about screening new biocontrol species and deeply studied biocontrol molecular mechanisms are provided for further research on the biocontrol of soybean diseases.

“…The higher organic matter content in the RS system can be attributed to its relatively closed environment, such as occurs in a greenhouse, where soil microorganisms may be the main source of epiphytic fruit fungi ( Dong et al, 2021 ). Species in the order Hypocreales have been reported to exhibit an inhibitory effect on mycelial growth, hyphal formation, and ascospore germination, of the fungal pathogen, Sclerotinia sclerotiorum , on soybean plants ( Peitl et al, 2020 ). Therefore, members of this order are ideal candidates for use as biological control agents.…”

A Comparative Analysis of the Microbiome of Kiwifruit at Harvest Under Open-Field and Rain-Shelter Cultivation Systems

et al. 2021

The composition of microbial communities can directly affect fruit quality, health status, and storability. The present study characterized the epiphytes and endophytes of “Hongyang” and “Cuiyu” kiwifruit at harvest under grown under open-field (OF) and rain-shelter (RS) cultivation systems. Disease incidence in kiwifruit was significantly lower (p < 0.05) under the RS system than it was under the OF system. High-throughput sequencing [16S V3-V4 ribosomal region and the fungal internal transcribed spacer (ITS2)] was conducted to compare the composition of the epiphytic and endophytic microbial community of kiwifruit under the two cultivation systems. Results indicated that the abundance of Actinobacteria, Bacteroidetes, Enterobacteriales, Acetobacterales, Sphingomonas, Pseudomonas, and Sphingobacterium was higher under the RS system, relative to the OF system, while the abundance of Capnodiales, Hypocreales, Vishniacozyma, and Plectosphaerella was also higher under the RS system. Some of these bacterial and fungal taxa have been reported to as act as biocontrol agents and reduce disease incidence. Notably, the α-diversity of the epiphytic bacterial and fungal communities on kiwifruit was higher under RS cultivation. In summary, RS cultivation reduced natural disease incidence in kiwifruit, which may be partially attributed to differences in the structure and composition of the microbial community present in and on kiwifruit.
