“…Temperature can play a significant role in the effectiveness of ASD treatments (Butler et al, 2014b;Ebihara and Uematsu, 2014), but temperatures at both locations in this study resulted in anaerobic conditions, indicating that C application was adequate under both temperature regimes. Soil disinfestation treatments had no influence on soil temperature.…”

“…The exposure of stored samples to the ubiquitous fungi and their spores to a mildly anaerobic condition would encourage more fungal growth than the aerobic conditions of field. 20,21 This might explain the higher fungi occurrence in stored samples than those from the field. It was observed in this study that the most active inhibitor of fungal growth was Annona muricata, and followed by Ocimum gratissimum and C. citratus.…”

Fungi have been associated with man from ancient times. Among these fungi, Aspergillus was first described in 1729. 1,2 For over three centuries approximately 250 species have been recognized in the genus. 3,4 Some species of Aspergillus have negatively affected man in so many areas of life, both medically and commercially. Constant inhalation of spores of Aspergillus species had resulted in some predisposition of humans and other animals to Aspergillosis. Mechanism of toxin production by Aspergillus species in foods are still being studied as some Aspergillus species may also produce toxic compounds (Mycotoxins) which presents a serious health risk for both man and animals. 5,6 There are different types of mycotoxins identified, with some being harmful to man and animals, e.g. zearalenone, fuminosins, aflatoxins, ochratoxins, vomitoxins, etc. [7][8][9] Aflatoxin was discovered in 1960 in England where close to 100,000 turkey poults died from aflatoxinpoisoning after eating peanut meal contaminated with Aspergillus flavus. [10][11][12] The discovery led to a growing awareness of the potential hazards (aflatoxicosis) of these substances as contaminants of food and feed; causing illness and even death in humans and animal. 10 Maize (Zea mays L.), along with wheat (Triticuma estivum L.) and rice (Oryza sativa L.), are the primary staple food cereals in many countries. 13

“…Laboratory experiments showed that under anaerobic conditions, the growth of Fusarium oxysporum f. sp. fragariae was greatly inhibited and the fungus growth and survival were suppressed with increasing temperature at 10-30 • C [48]. In field trials with 280-300 h of soil temperatures above 30 • C at 20 cm depth of the soil, F. oxysporum was consistently suppressed by ASD [48].…”

Maltose and Totally Impermeable Film Enhanced Suppression of Anaerobic Soil Disinfestation on Soilborne Pathogens and Increased Strawberry Yield

Anaerobic soil disinfestation (ASD) is widely used to control soilborne diseases in organic crop production. The effect of ASD used different sealed films on soilborne pathogens and strawberry growth was evaluated in two laboratory studies and two field trials. Under maltose as carbon sources, 28 °C temperature and 30% of soil moisture optimal conditions ASD decreased Fusarium spp. and Phytophthora spp. by 100%. ASD used maltose as an organic amendment and sealed with totally impermeable film (TIF) obtained the highest suppression (>96%) against Fusarium spp. and Phytophthora spp. (>91%). According to the laboratory results, the efficacy of ASD utilizing 6 or 9 t/ha maltose and sealing with TIF was evaluated and compared with reference treatment with chloropicrin (Pic) or solarization (Sol) in the field trials. Compared with the untreated soil, ASD treatments greatly reduced the pathogenic population of Fusarium spp. and Phytophthora spp., and successfully controlled the damage of fusarium wilt with evidence of lower mortality (6%). ASD significantly increased soil nutrition promoted plant growth and increased strawberry yield, which was similar as the Pic, but better than Sol treatment. The analyzed fungal and bacterial microbiota did not show significant differences in the taxonomic richness and diversity between the compared treatments. Nevertheless, the abundance of some bacterial and fungal taxa tended to change between treated. The evidence showed that adding maltose and sealing TIF for ASD has the potential to replace Pic for pathogen control in commercial strawberry production.
