“…The synergistic effect of Brassica carinata meals combined with the mycoparasite Coniothyrium minitans against Sclerotinia sclerotiorum and S. minor has been demonstrated under controlled conditions (Marciano et al 2004). Control of sugar beet damping-off caused by Pythium ultimum can be improved with a combined incorporation of Brassica carinata seed meal and selected tolerant strains of Trichoderma (Galletti et al 2008).…”

The use of Brassica crops as green manure in the so-called biofumigation treatment has been successfully exploited for the management of soilborne pathogens and is gaining interest particularly in the case of less intensive agricultural systems. A study was undertaken to investigate possible negative sideeffects of biofumigation in order to prevent possible damage caused by wilt pathogens able to attack both plants used for biofumigation as well as agricultural crops. To do so, firstly the response of different Brassicas, including some used in biofumigation, to the formae speciales of Fusarium oxysporum known for being pathogenic on Brassica crops was evaluated.

“…While decomposing Brassica litter can dramatically decrease fungal diversity (Hollister et al 2013;Mazzola et al 2015), living brassicas may not be broadly anti-fungal as they are susceptible to specific fungal pathogens, e.g., Olpidium brassicae (Bennett et al 2014). Further, some diseaseprotective fungi, such as Trichoderma, have been shown to respond positively to both seed meal (Galletti et al 2008) and living Brassica plants ( Kirkegaard et al 2004). Because much of the research surrounding brassicas has focused on their use as seed meals or green manures and thus is most relevant only to replant situations, future work should investigate their potential to shape microbial communities as living plants within a cover crop system as they are often planted as part of a mix or occur naturally as weedy species.…”

“…As a result, it was suggested that Trichoderma spp. applied in conjunction with B. carinata seed meal could achieve superior control of Pythium ultimum (Galletti et al 2008). Such an approach may not be essential in all systems as B. juncea SM was found to induce proliferation of native Trichoderma spp.…”

“…Allyl isothiocyanate generated in response to incorporation of B. juncea SM into soil exhibits activity towards a broad spectrum of soil organisms including a diversity of plant pathogenic fungi, oomycetes and plant-parasitic nematodes (Manici et al 1997;Zasada and Ferris 2004;Mazzola et al 2007;Galletti et al 2008). In this study, the generation of AITC in B. juncea SM amended soil was initiated within 1 h of seed meal application and consistently declined within 4-7 h when applied at a rate of 0.3% wt/wt.…”

Brassica juncea seed meal particle size influences chemistry but not soil biology-based suppression of individual agents inciting apple replant disease

Apple replant disease is incited by a pathogen complex composed of multiple fungal, oomycete and nematode species. Rhizoctonia solani AG-5 can be a significant component of this complex and is effectively suppressed via multiple functional mechanisms in response to Brassica juncea seed meal (SM) amendment. These mechanisms include those of both a biological and chemical nature. The effect of seed meal particle size on the operation of these mechanisms and the resulting capacity of B. juncea SM to suppress R. solani and other components of the pathogen complex that incites replant disease of apple was examined in this study. Emission of ally isothiocyanate (AITC) from B. juncea SM-amended soil was initiated earlier and reached higher maximal concentrations in soils amended with fine particle (<1 mm dia) than coarse particle (2-4 mm dia) size SM. This corresponded with the level of disease suppression obtained when R. solani AG-5 and SM at a rate of 0.3% (wt/wt) were introduced concurrently into soils and planted to apple; fine particle size but not coarse particle size B. juncea SM suppressed apple root infection. At the same rate, Pratylenchus penetrans and Pythium spp. were effectively controlled by B. juncea SM applications irrespective of SM particle size. AITC emission from B. juncea SMamended soils was completed within 72 h post amendment, even at an application rate as high as 1.0% (wt/wt). In both fine and coarse particle size B. juncea SM-amended soils, populations of resident Streptomyces spp. were elevated approximately five to ten-fold at 8 weeks post-application relative to the non-treated control soil. When soil was infested with R. solani AG-5 subsequent to this 8 week incubation period and planted to apple, B. juncea SM amendments effectively suppressed Rhizoctonia root rot irrespective of SM particle size. Relative R. solani AG-5 apple root infection as determined by culturebased methods and a qPCR method developed in these studies was consistently similar across experiments. These findings demonstrate that particle size will affect the efficacy of B. juncea SM soil amendment for the control of R. solani AG-5, but will do so only through effects on chemistry-and not biologically-based mechanisms of pathogen suppression.
