“…In this study, potentially beneficial bacteria in healthy strawberry rhizosphere soils were much more than in anthracnose-infected plants, and isolation of antagonistic bacteria from healthy samples may be much easier than from diseased samples. Species within Trichoderma were widely studied for biocontrol of strawberry fungal diseases, such as black root rot (Asad-Uz-Zaman et al, 2015 ), Armillaria root rot (Raziq and Fox, 1999 , 2005 ; Pellegrini et al, 2014 ), root rot (El-Fiki and Ahmed, 2017 ), powdery mildew (Fiamingo et al, 2007 ), and strawberry anthracnose (Freeman et al, 2004 ; Porras et al, 2009 ; Karimi et al, 2017 ; Zhao et al, 2020 ). In this study, the relative abundances of Trichoderma in hRZ (1.881%) and dRZ (1.452%) were similar and did not show a significant difference ( P > 0.05) (data not shown), but the beneficial fungal species T. asperellum showed a higher relative abundance in healthy strawberry rhizosphere soils.…”

Anthracnose caused by Colletotrichum spp. was widespread in recent years and resulted in great damage to strawberry production. Soil microbial communities were key contributors to host nutrition, development, and immunity; however, the difference between the microbial communities of healthy and anthracnose-infected strawberry rhizosphere soils remains unclear. In this study, the Illumina sequencing technique was used to comparatively study the prokaryotic and fungal community compositions and structures between healthy and anthracnose-infected strawberry rhizosphere soils in Yuxi, Yunnan Province. Both microbial community diversities and richness of anthracnose-infected strawberry rhizosphere soils were higher than those of healthy strawberry rhizosphere soils. A total of 2,518 prokaryotic and 556 fungal operational taxonomic units (OTUs) were obtained at the 97% similarity threshold. Proteobacteria, Thaumarchaeota, and Acidobacteria were the dominant prokaryotic phyla; Ascomycota, unclassified_k__Fungi, and Mortierellomycota were the dominant fungal phyla. The relative abundances of beneficial bacterial phyla Actinobacteria and Firmicutes, genera Streptomyces, Azospirillum, and Bacillus were significantly reduced in anthracnose-infected strawberry rhizosphere soils; the relative abundance of beneficial fungal species Trichoderma asperellum shows a similar tendency with bacterial abundance. Besides Colletotrichum, 15 other potential fungal pathogen genera and seven fungal pathogen species were identified; among the potential pathogen genera and species, eight pathogen genera and Fusarium oxysporum showed significant differences between healthy and anthracnose-infected strawberry rhizosphere soils. The results suggested that strawberry planted in this area may be infected by other fungal pathogens except for Colletotrichum spp. Our present research will provide theoretical basis and data reference for the isolation and identification of strawberry pathogens and potential probiotics in future works.

“…Once this pathogen gets established in soil, it becomes extremely difficult to eradicate from the crop field (Bolton et al, 2010). The continuous infection of this fungus can lead to eventual death of plant causing rot in crown and root region (Zaman et al, 2015). Citrus industry is one of the major fruit industries in Nepal contributing total of 22.37% of total food production, so the management of such diseases in citrus seedling is crucial.…”

Crown and root rot disease was among the major problems in acid lime (Citrus aurantifolia) seedlings grown in the nursery of Warm Temperate Horticulture Centre, Kirtipur, Nepal. Samples of the diseased plants were investigated at the laboratory of Nepal Plant Disease and Agro Associates. Rhizoctonia solani, Fusarium solani and Alternaria citri were found associated with the disease samples. On pathogenicity testing R. solani showed symptoms like those of the infected seedlings. Hence, a pot experiment was conducted in a completely randomized design with four replications to manage the disease. Acid lime seedlings grown in sterilized soil and inoculum of R. solani prepared in potato dextrose agar (PDA) were used for the experiment. The treatments included carbendazim 50WP @ 1000 ppm, Trichoderma viride @ 2 ml/l water, Pseudomonas fluorescens @ 2 ml/l water, A-arya 009 (essential oil and organic acids) @ 1 ml/l water, and control (water) which were applied by soil drenching before 15 days of pathogen inoculation. Carbendazim at 100 and 200 ppm was also evaluated against R. solani by poison food technique on PDA. In the pot culture, the effect of treatments was significant on the growth of root and shoot of seedlings and both disease incidence and severity. Carbendazim had significantly least disease incidence (43.75%) and least disease severity (18.75%) among the treatments 45 days after inoculation with the pathogen. Also, the fungicide at 100 ppm gave complete inhibition of R. solani in PDA culture. Hence, carbendazim could be suggested for the management of the citrus crown and root rot caused by R. solani. However, further study is required to find out appropriate concentration of the fungicide for effective management of disease.

“…Plants that have been affected lack feeder roots, and many of the bigger roots have broken off at rotten locations where the cortical tissue has collapsed. Because of root rot, some plants lose their lives throughout the growing season, whereas those that survive will be stunted and will yield fewer strawberries [58]. The genus Pythium (Pythiaceae, Oomycota) has 327 described species [59].…”

Strawberry production remains important in the world. Soil-borne fungal pathogens (such as Macrophomina phaseolina, Rhizoctonia spp., Fusarium oxysporum, Phytophthora spp., and Pythium spp.) are causing serious problems for strawberry farmers. Distinct treatments, such as fumigation, resilient varieties, solarization, rotating crops, synthetic fungicides, and cultural practices are used to combat infections of soil-borne in strawberries. Since strawberry fruits are consumed immediately, fungicide treatments raise a number of problems, including pesticide residue on the fruits which gives harmful effects on consumers. Solarized soils are often effective against certain soil-borne pathogens. New studies have focused on eco-friendly biological control agents (BCAs) that can be used as effective substitutes for fungicides. Trichoderma strains are efficient BCAs that have different mechanisms against soil-borne diseases in strawberries. Despite the success of commercial Trichoderma-based products, their low efficacy or ineffectiveness against targeted pathogens are major limitations under field conditions. Native Trichoderma strains that can be used to control this disease are ideal antagonists. This section discusses the potential of native Trichoderma strains to combat soil-borne pathogens in strawberry fields.
