“…In the 1980s crown rot became favoured by farming practices, such as conservation tillage, in which infested residues were retained on the soil surface (Summerell et al 1989). An outbreak of head blight of wheat was caused by this species in northwest New South Wales in 1983, an exceptionally wet season .…”

“…F. graminearum group I) in wheat and barley resulted in 54% diseased tillers when residues were retained, while fewer than 10% diseased tillers occurred when stubble was burned (Dodman and Wildermuth 1989). Increased stubble retention also increased the incidence of fusarium crown rot, whereas stubble burning usually reduced the disease incidence (Summerell et al 1989). The finding that Fusarium spp.…”

Abstract:The influence of shallow (20 cm deep) subsoil tillage on cereals planted with a no-till planter was investigated for 3 years at two locations in southeastern Idaho. Among Fusarium spp., F. culmorum was the primary fungus isolated from diffuse brown-black root lesions in the wetter location (Ririe), while F. semitectum, F. reticulatum, F. equiseti, and F. acuminatum were the dominant species isolated at the drier location (Arbon Valley). Increased yields resulting from methyl bromide fumigation indicated that biological factors were limiting the yield. However, subsoiling did not influence nematode populations or fungal root rots. The primary parasitic nematode found at both locations was Pratylenchus neglectus. Subsoiling had a tendency to increase soil moisture at depths between 61 and 90 cm, to increase organic matter, and to decrease nitrogen. Yield increased by 8% or more with subsoil tillage at both locations the first year. Yield increases were not significant in other years, when moisture was particularly limiting or abundant. Subsoiling may prove favorable for cereals planted in a soil-conservation tillage system, but the risk of fungal root rots may increase with such a practice. Additional study is warranted, as subsoil-tillage practices may increase yield and desirable soil parameters without compromising the benefits associated with cereal production in a soil-conservation tillage system. Key words: Fusarium spp., fusarium root rot, direct seeding, dryland, subsoiling, no till, zero tillage.Résumé : L'effet d'un sous-solage superficiel (20 cm de profondeur) sur des céréales plantées avec un planteur pour le semis direct a été étudié pendant 3 ans à deux sites du sud-est de l'Idaho. Parmi les espèces du Fusarium, le F. culmorum a été le principal champignon isolé de lésions racinaires floues brun noir au site le plus humide (Ririe), alors que les F. semitectum, F. reticulatum, F. equiseti et F. acuminatum ont été les espèces dominantes isolées du site le plus sec (vallée d'Arbon). Des augmentations de rendement résultant de fumigation au bromure de méthyle ont révélé que des facteurs biologiques limitaient les rendements. Par contre, le sous-solage n'a pas eu d'effet sur les populations de nématodes ou sur les pourritures racinaires fongiques. Le Pratylenchus neglectus fut le principal nématode parasite retrouvé aux deux sites. Le sous-solage avait tendance à augmenter la teneur en eau du sol aux profondeurs entre 61 et 90 cm, à augmenter la matière organique et à diminuer l'azote. Avec le sous-solage, les rendements ont augmenté de 8% ou plus aux deux sites au cours de la première année. Lors des autres années, les augmentations de rendement n'étaient pas significatives lorsque l'eau était particulièrement limitée ou abondante. Le sous-solage peut s'avérer profitable pour les céréales plantées dans un système de conservation des sols, mais une telle pratique pourrait accroître le risque de pourriture racinaire fongique. Des études supplémentaires sont souhaitables puisque les pratiques de so...

“…Previous studies of the influence of stubble management on crown rot (Klein et al 1988;Dodman and Wildermuth 1989;Summerell et al 1989;Burgess et al 1993;Wildermuth et al 1997) have usually compared the incidence of infection at the end of the season. In most published comparisons, stubble incorporation had no significant effect on terminal incidence compared with stubble retention on the surface.…”

The influence of surface soil moisture and stubble management practices on the progress of infection of wheat by Fusarium pseudograminearum, the cause of crown rot, was assessed in a field trial at Moree in northern New South Wales during the growing seasons of 1994, 1995 and 1996 by analysis of infection progress curves. During the dry season of 1994, wheat was sown into dry surface soil. Increases in incidence of infection followed rainfall events that raised the water content of the surface soil above the equivalent of a water potential of –1.5 MPa. The rate of increase in incidence of infection was more uniform in the 1995 and 1996 seasons, which had more regular rainfall. The area under the infection progress curve (AUIPC) was consistently greater when stubble was retained on the surface compared with incorporation with a disc plough, and this difference was significant in 2 out of 3 years. Comparison of AUIPCs indicated greater epidemiological differences between stubble management treatments than did comparisons of incidence of infection at single points during the season.
