... The cultivation of NUPs that are tree species inevitably falls into the principles of orchard management. According to these principles, organic management mainly considers diversification in terms of lower inputs or inputs with a lesser environmental impact for fertilization, crop protection and/or water management, as opposed to conventional management, where traditionally no such limitations apply [39,40]. A large body of evidence from the literature supports the environmental sustainability of organic tree crop management compared to conventional systems as part of an integrated or diversified management system [41][42][43][44]. ...

... In particular, Bremia lactucae, responsible for downy mildew, and Botrytis cinerea, responsible for grey mold, are two of the most destructive aerial pathogens of lettuce plants worldwide [2]. Other important phytopathogens are those that are soilborne, causing general symptoms such as: basal rot disease, which is associated with several species of Pythium and Phytophthora cryptogea; basal leaf decay, which is associated with Rhizoctonia solani, Sclerotinia sclerotiorum, and S. minor [3][4][5][6][7]; southern blight disease, caused by Athelia rolfsii; and vascular diseases (wilt), associated mainly with Fusarium oxysporum f.sp. lactucae [8]. ...

... Anaerobic Soil Disinfestation (ASD) is an alternative to fumigation used in a variety of crops and to manage a wide range of pests, weeds and diseases (Blok et al. 2000;Shennan et al. 2014b;Lopes et al. 2022;Mazzola, Muramoto, and Shennan 2018;Shennan et al. 2016;Zavatta et al. 2021), gaining global popularity (Khadka et al. 2020;Shennan et al. 2014b;Priyashantha and Attanayake 2021;Rosskopf et al. 2020;Shennan et al. 2018;Vecchia et al. 2020). The method creates an anaerobic soil environment before planting, by adding a carbon source to the soil such as wheat bran, molasses, rice straw, or rice bran to promote microbial growth and respiration, followed by plastic tarping and irrigation (Momma 2008;Shennan et al. 2018). ...

... Botryosphaeriaceae is a fungal family comprising almost 500 species of plant pathogens [19], including M. phaseolina, the causal agents of charcoal rot in common bean [20] and other legumes, as well as root rot [8,9]. Nevertheless, this pathogen has been isolated from different plant species, such as: strawberry, peanut and basil [14,21,22]. The wide range of infected hosts and the ubiquitous geographic distribution of M. phaseolina make it one of the most studied emerging pathogens all over the globe. ...

... As a result of these limitations, plants treated with SoS chemicals, including more recent materials such as isoxazolines (e.g., oxathiapiprolin = Segovis ® , Zorvec ® ), can still become infected by Phytophthora (Benson 1987, Hamm et al. 1984, Ji et al. 2014, Matheron and Porchas 2015, Rupp et al. 2016, Tjosvold et al. 2008). If levels of SoS chemicals are high enough in the host tissue, subsequent pathogen growth and reproduction will be suppressed. ...

... Síntomas como amarillamiento y marchitamiento de hojas maduras, marchitamiento de hojas jóvenes y necrosis marrón en la corona se reportaron en Brassica rapa L. subsp. rapa, afectada por R. solani ag 2-1 [31]. En el tomate (Solanum lycopersicum L.), R. solani causa lesiones irregulares y húmedas, de color marrón y de aspecto hundido, en los tallos de las plantas jóvenes y, en plantas maduras, marchitamiento y daño del tallo con cancro marrón en la corona de este [4]. ...

... For example, Fusarium oxysporum f. sp. fragariae was suppressed by ASD only when the cumulative hours at temperatures >30°C at 20-cm soil depth exceeded 467 h, which was accomplished under mean air temperature of 15°C in coastal California (Muramoto et al. 2020). A meta-analysis of ASD efficacy against Fusarium oxysporum suggested that ASD was effective in suppressing this pathogen when the soil temperature was >25°C (Shrestha et al. 2021). ...

... Sclerotinia sclerotiorum has been detected in air samples from an outdoor cannabis field (Green et al. 2018). Sclerotinia stem canker was previously reported on hemp in Alberta (Bains et al. 2000) and New Brunswick (Gauthier et al. 2020) and Sclerotinia crown rot has been reported from California on hemp grown after a lettuce crop (Koike et al. 2019) but this is the first report of Sclerotinia bud rot on cannabis. ...

KBC medium (Mohan and Schaad 1987) is widely used for the isolation of bacteria in the P. syringae group (Asaad et al. 2017;Bull and Koike 2017;Randhawa et al. 2017;Shepherd and Block 2017).
