“…Their incorporation to the growing substrate had significantly decreased disease severity and treated plants were significantly comparable to the unamended and uninoculated control ones. The present results confirmed earlier reports on the suppressive effects of composts, based on orange fruit waste, grass clippings and grape marc, against S. rolfsii in turfgrass [40]. Moreover, Danon et al [41] demonstrated that the disease incidence on bean germination was decreased by 65 to 70% using compost compared to the inoculated and untreated controls.…”

Stem rot caused by Sclerotium rolfsii is one of the most devastating disease in tomato.An integrated management strategy implementing potential biotool is required to control this disease. Thus, five on-farm composts were evaluated for their ability to control tomato stem rot and to promote plant growth. The tested composts, except C 1 , were effective in decreasing disease severity from 31.2 to 56.2%, with a significant similarity between pathogen-inoculated plants treated with C 3 and C 4 and disease-free and untreated controls. Treatments with C 2 and C 4 had significantly enhanced most tomato growth parameters: stem diameter, and dry weights of aerial part and roots. A similar effect was noted for C 3 -based treatment on the plant height, the stem diameter, and the root dry weight where the recorded increments as compared to control were estimated at 16.9%, 23.8%, and 80%, respectively. Tested on S. rolfsii-free plants, compost C 4 was the most efficient in improving all tomato growth parameters by 28.8, 8.54, 92.2 and 80% in their height, stem diameter and aerial part and root dry weights, respectively. A similar significant effect was observed on tomato plants challenged with composts C 2 and C 3 . This work demonstrated the ability of composts to control tomato stem rot and to enhance the plant growth.

“…The use of cheaper media and alternative approaches for mass production could also reduce the costs of microbial production, making them economically more competitive with other control methods. The use of waste derived from agriculture (for example, crop residues) or the food industry to obtain composts is an interesting approach to producing enriched substrate for the production of biocontrol agents for plant disease and nematode control 32,33 . In addition, composts are known for their potential as fertilizers owing to their high organic matter content.…”

Root parasitic weeds of the genera Orobanche and Phelipanche (commonly named broomrapes) are responsible for enormous yield losses of several crops all around the world. Traditional weed management methods, including among others the use of herbicides, soil fumigation and solarization, and mechanical, agronomic or physical methods, may have limits of use or can provide a modicum of control. Difficulties in controlling parasitic weeds are due to both the enormous number of seeds produced by each plant that can remain viable for many years, even in the absence of a host, and to the unique physiological and biological properties of the parasite. Although long considered a suitable and promising approach, biological control, in particular the use of microbial organisms or compounds stimulating or inhibiting seed germination, has had no commercial success and no products have reached the market. This article provides a quick overview of the bioherbicide approaches attempted until now, briefly discussing the causes of the failures and the possibility to improve biocontrol agents’ effectiveness. Indeed, despite the failures, the ‘bioherbicide’ approach deserves renewed interest in light of the enormous scientific and technological progress made in past years, which offers new chances of success. © 2023 The Author.

“…Additionally, T. atroviride also has relatively good adaption to different conditions and good inhibition ability; T. atroviride grew fast and effectively inhibited the growth of the four tested phytopathogens and could also mycoparasitise three of the four phytopathogens, except for F. oxysporum . This result is similar to that of a previous study, in which T. atroviride isolated from organic composts was reported to successfully control the disease of Clarireedia spp., Rhizoctonia solani , and Sclerotium rolfsii , which showed 53.5, 69.3, and 43.5% less affected area, respectively, on Agrotis stolonifera compared to the control ( Coelho et al, 2021 ). The number of T. atroviride isolates was the greatest and accounted for 57% of the total number, while the number of isolated T. asperelloides accounted for only 8%.…”

White birch (Betula platyphylla Suk.) is a typical pioneer tree species that is important in forest restoration in northern China, Japan, and Korea. In the present study, 37 isolates were obtained from B. platyphylla rhizosphere soils in Heilongjiang Province; they were identified as T. pleuroticola (3 isolates), T. virens (2 isolates), T. hamatum (8 isolates), T. atroviride (21 isolates, dominant species) and T. asperelloides (3 isolates). Stress tolerance tests (salt, alkali, and nutritional stress that simulated saline alkali or barren soil) and confrontation assays (with four pathogens) were performed to determine which isolates had good biocontrol ability in barren soil; the results show that T. atroviride was outstanding. Then, in order to determine the effect of T. atroviride on plants and soil, Gynura cusimbua seeds were sown and treated with a T. atroviride spore suspension, as was unsown soil. The seedlings treated using T. atroviride had significantly greater height, stem diameter, soluble protein content, soluble sugar content, and malonaldehyde (MDA) content and their catalase (CAT) activity was also significantly increased. In addition, when the plants were inoculated with Alternaria alternata, the plants treated using T. atroviride had stronger CAT activity, significantly higher soluble protein content and soluble sugar content, and significantly lower MDA content, which indicates stronger resistance and less injury caused by the pathogen. In addition, T. atroviride not only increased the content of available nitrogen and available phosphorus in the soil, but also promoted G. cusimbua seedlings’ absorption of available nitrogen and available phosphorus. Thus, the characteristics of T. atroviride may make it the main factor that helps B. platyphylla colonise cut-over lands. T. atroviride, a promising biocontrol candidate, can be used in agriculture and forestry.
