“…Despite the high initial infestation, solarisation was highly effective in the reduction of populations of S. cepivorum to negligible levels, thus confirming previous results in the first two experiments (Melero-Vara et al, 1989;Satour et al 1989;Basallote-Ureba & Melero-Vara, 1993).…”

Soil solarisation was consistently efficacious in reducing inoculum density to undetectable levels in a field naturally-infested with Sclerotium cepivorum. This treatment delayed epidemic onset of white rot of garlic 2-3 months as compared with the untreated control or the inoculation of planting furrows with Glomus intraradices. Furthermore, significant reductions of disease incidence and of the standardised AUDPC were also observed in solarised plots, resulting in quantitative and qualitative yield improvement. Similar effects were observed in plots planted with tebuconazole-treated cloves, confirming previous results, whereas Trichoderma harzianum was ineffective as a biocontrol agent, when applied to planting furrows. The inoculation of plots with G. intraradices before planting, in three consecutive years, was neither effective for disease control nor on the development of garlic, although the root systems of garlic plants from all the experimental treatments were heavily mycorrhizal at harvest, indicating the presence of native arbuscular mycorrhizal propagules in the soil and their survival after soil solarisation.

“…Nevertheless, today there are only a few methods to control Fusarium basal rot diseases in commercial fields in Israel. Such practices include soil solarization [30], four-year crop rotation for onions, including avoidance of other members of the lily family, and breeding alliaceous crops for pest resistance [3]. In addition, using fludioxonil, thiophanate methyl [9], or metam sodium (formally a dithiocarbamate used for soil disinfection) as a pre-planting dip can provide some protection.…”

Over the past decade, there have been accumulating reports from farmers and field extension personnel on the increasing incidence and spread of onion (Allium cepa) bulb basal rot in northern Israel. The disease is caused mainly by Fusarium species. Rotting onion bulbs were sampled from fields in the Golan Heights in northeastern Israel during the summers of 2017 and 2018. Tissue from the sampled onion bulbs was used for the isolation and identification of the infecting fungal species using colony and microscopic morphology characterization. Final confirmation of the pathogens was performed with PCR amplification and sequencing using fungi-specific and Fusarium species-specific primers. Four Fusarium spp. isolates were identified in onion bulbs samples collected from the contaminated field: F. proliferatum, F. oxysporum f. sp. cepae, and two species less familiar as causative agents of this disease, F. acutatum and F. anthophilium. Phylogenetic analysis revealed that these species subdivided into two populations, a northern group isolated from white (Riverside cv.) onion bulbs, and a southern group isolated from red (565/505 cv.) bulbs. Pathogenicity tests conducted with seedlings and bulbs under moist conditions proved that all species could cause the disease symptoms, but with different degrees of virulence. Inoculating seeds with spore suspensions of the four species, in vitro, significantly reduced seedlings’ germination rate, hypocotyl elongation, and fresh biomass. Mature onion bulbs infected with the fungal isolates produced typical rot symptoms 14 days post-inoculation, and the fungus from each infected bulb was re-isolated and identified to satisfy Koch’s postulates. The onion bulb assay also reflected the degree of sensitivity of different onion cultivars to the disease. This work is the first confirmed report of the direct and primary cause of Fusarium onion basal rot disease in northeastern Israel. These findings are a necessary step towards uncovering the mycoflora of the diseased onion plants and developing a preventive program that would reduce the disease damage.

“…The long-term effect of solarization reported in various studies (e.g. Katan et al, 1983;Tjamos & Paplomatas, 1988;Satour et al, 1989;Stevens et al, 2003) supported the notion of a shift in the soil equilibrium that is suppressive to the pathogen, which could be connected to the physical, chemical and biological processes occurring in the soil during and after solarization. Many studies have shown that biological control processes are induced or stimulated in the solarized soil, thus contributing to pathogen control.…”
