“…It was previously shown that FRR on White beans was more severe at 21°C than at 14°C or 28°C, while bean growth and dry weight were higher at 28°C than at soil temperatures of 14°C or 21°C (Sippell and Hall 1982). Higher disease levels occurring at V3 when planting coincided with cooler and moister weather conditions in May than in June seem to confirm earlier reports that the most severe FRR in beans occurred in fields planted in cold and moist soils (Burke and Miller 1983).…”

The relationships between a number of agronomic practices, Fusarium root rot (FRR) measurements and yield variables were characterized at different growth stages in 122 commercial bean fields in Zanjan, Iran. Mean FRR incidence, severity and index differed among growth stages and years. A lower FRR index at growth stage R9 and higher yields were detected in Red beans compared to Pinto and White beans. FRR severity affected the number of pods and seeds per plant. Despite the lack of an impact of initial drought on FRR and yield factors, FRR levels were higher following frequent irrigations at 2-3 days intervals than at longer intervals at R6-7. The highest FRR index at R6-7 (51.9%) and incidence at R9 (69.1%) were associated with the densest category of plant populations. Yield components differed significantly between the levels of plant density at R9. FRR levels at V3 were lower for June plantings than for May-second-week plantings. Lower FRR ratings and higher yields were detected at a seeding depth of 0-5 cm in comparison to 10-20 cm.At R9, FRR levels on beans following maize were lower than those following barley, bean, tomato or wheat. At V3, FRR severity was greater in fields that received 50-500 kg/ha of urea compared to nonfertilized fields. Greater mean FRR index at R6-7 and lower yield levels were associated with the greatest weed density compared to weed-free fields. This new information benefits the systematic understanding of interactions between bean yield, FRR and various agronomic variables at large-scale.

“…increased as the temperature increased from 5 to 258C (Mu¨ndel et al 1995), and Pythium spp. were most virulent on bean at 14Á218C (Sippell and Hall 1982). These contrasting results may arise from the inherent robustness of the host species used in the previous studies.…”

Hwang, S. F., Ahmed, H. U., Turnbull, G. D., Gossen, B. D. and Strelkov, S. E. 2015. Effect of seeding date and depth, seed size and fungicide treatment on Fusarium and Pythium seedling blight of canola. Can. J. Plant Sci. 95: 293–301. Seedling blight has a substantial impact on stand establishment and productivity of canola (Brassica napus) on the Canadian prairies. The effects of seeding date, seed size, seeding depth, and seed treatment fungicides on seedling blight of canola caused by Fusarium avenaceum and Pythium ultimum were evaluated under field conditions. In the trials inoculated with P. ultimum, early seeding reduced seedling emergence and seed yield in all 3 yr of the study. However, the interaction of F. avenaceum with seeding date was not consistent; inoculation with F. avenaceum reduced seedling emergence in early seeded canola in 1 of 4 yr, but emergence was higher in early than in mid-seeded treatments in 2 yr and there was no difference among seeding dates in 1 yr. Late seeding reduced seed yield in 2 of 4 yr in the F. avenaceum study. Seed size and seeding depth generally did not have an effect on seedling establishment or seed yield for either pathogen. Seed treatment with Helix Xtra (thiamethoxam+difenconazole+metalaxyl+fludioxonil) and Prosper FX (clothianidin+carboxin+trifloxystrobin+metalaxyl) fungicides increased seedling emergence and yield compared with the F. avenaceum-inoculated control. Seed treatment with Helix Xtra also increased seedling emergence and seed yield compared with the P. ultimum-inoculated control. Manipulation of seeding date did not substantially improve stand establishment or yield of canola when inoculum pressure was high. Seed treatment was the most effective strategy for reducing losses caused by seedling blight of canola in fields infested with F. avenaceum or P. ultimum.

“…Warm temperatures and low soil moisture content enhances the virulence of R. solani (Pieczarka and Abawi 1978). As a result, the incidence of infection is higher in warm dry soils than in cool, wet soils (Bhatti and Kraft 1992;Sippell and Hall 1982).…”

“…Soil temperature and moisture are the primary determinants of growth rate for seedlings and root pathogens of many crops (Hwang et al 2000 a,b;Kraft and Roberts 1969;Sippell and Hall 1982). The major factor influencing seedling blight and root rot severity on the Canadian prairies is seeding date (Bootsma and DeJong 1988).…”

. 2004. Effects of soil temperature, seeding depth, and seeding date on rhizoctonia seedling blight and root rot of chickpea. Can. J. Plant Sci. 84: 901-907. Rhizoctonia solani Kühn, a prevalent fungal pathogen in cultivated prairie soils, can be an important factor affecting seedling establishment of chickpea (Cicer arietinum L.). Studies were undertaken to determine the impact of different soil conditions on seedling establishment, development of root rot, and productivity of desi (Tyson) and kabuli (Sanford) chickpea plants sown in the presence of R. solani AG-4. The impact of soil and air temperatures and seeding depth was studied under controlled conditions, and the influence of seeding date was investigated at three field sites. The host responded to warm soils by increasing its growth rate, and the pathogen by increasing its virulence. The kabuli cultivar, Sanford, showed greater susceptibility to root rot caused by R. solani than the desi cultivar, Tyson. Root rot and shoot infection levels increased with soil temperature for both cultivars, but reached maximum values at substantially lower temperatures for Sanford. Shoot biomass of infected treatments for this cultivar was substantially lower than the controls, while the biomass of Tyson was affected to a lesser degree. Air temperatures of 17/3°C day/night allowed relatively unhindered plant growth, even of the more susceptible cultivar, Sanford, in the presence of R. solani, while warmer and cooler temperatures resulted in high mortality and diminished plant growth in surviving plants. Seedling emergence and seedling dry weight were greater at a seeding depth of 2 cm than at 5 cm for seedlings grown in infested soil. In inoculated field plots, seedling emergence was greatest in treatments seeded in late May to early June compared those seeded in early or mid-May; in noninoculated treatments, both emergence and yield were lower in treatments seeded in late May than at the earlier seeding dates. Seeding date did not affect the occurrence of root rot. Rhizoctonia solani Kühn, champignon pathogène courant dans les sols cultivés des prairies, peut nuire considérablement à l'implantation du pois chiche (Cicer arietinum L.). On a donc entrepris des études pour déterminer l'incidence de divers états du sol sur l'enracinement des plantules, l'apparition du pourridié et la productivité des pois chiches desi (Tyson) et kabuli (Sanford) semés en présence de R. solani AG-4. On a vérifié les effets de la température du sol et de l'air et de la profondeur des semis en milieu contrôlé, tandis que l'incidence de la date d'ensemencement a été évaluée sur le terrain à trois endroits. Quand le sol est chaud, la plante pousse plus rapidement, mais l'agent pathogène est plus virulent. Sanford (le cultivar kabuli) est plus sensible au pourridié causé par R. solani que le cultivar desi Tyson. La gravité du pourridié et le degré d'infection des pousses augmentent avec la température du sol chez les deux cultivars, mais atteint le maximum à une température nettement plus basse ...
