Fusarium head blight (FHB) is well established in the eastern prairies, but for the most part it has been absent from western regions, especially under dryland conditions. This has been largely attributed to dry and hot conditions during some years, and the limited occurrence of F. graminearum in the western prairies. It is of importance to prevent the movement of F. graminearum, the most important FHB pathogen in North America, to areas where this pathogen is not commonly found. Three controlled-environment studies, using different Fusarium-infected common and durum wheat seed lots, were conducted to determine the effectiveness of currently registered fungicide seed treatments in improving seedling emergence and plant development, and preventing the growth of F. graminearum from infected seed to plant tissue. Fungicide treatments improved seedling emergence from the most infected seed over the untreated infected control, but most treatments did not improve emergence in the other experiments. Plant growth in the fungicide treatments was either similar to or slower than in the untreated controls. Fusarium graminearum was isolated from discoloured tissue in all treatments and was generally more common in crowns than in subcrown internodes. No fungicide treatment reduced discolouration of plant tissue or percentage isolation of F. graminearum or other Fusarium spp. consistently. We conclude that while currently registered seed treatments might be effective in improving seedling emergence in some infected wheat seed lots, they do not prevent the growth of F. graminearum from seeds to plant tissue. For the western prairies, the use of fungicide seed treatments as a strategy in the prevention of spread of FHB would require that they be effective primarily against F. graminearum. Performance of fungicide seed treatments against Fusarium-infected wheat seed should also be determined under typical growing conditions across the western prairies.Key words: Seed treatments, fungicides, wheat, root rot, crown rot, Fusarium graminearum, Fusarium avenaceum

Small and marginal farmers have little access to improved seed from institutional sources and are thus largely excluded from the benefits of new varieties. The production and storage of improved varieties seeds at the household (HH) level can successfully overcome this problem. With this aim CSISA-CIMMYT (Cereal Systems Initiative for South Asia) project in Bangladesh have been working since 2012. Therefore, the study assessed the impacts of wheat seed storage systems at HH level, with a particular emphasis on how the poor farmers are benefited by doing the seed storage business. The study analyzed data and information collected at random from 210 supported and 60 non-supported farmers spread over three wheat growing districts namely Mymensingh, Faridpur and Rangpur. Wheat farmers used different storage containers and showed the highest level of satisfaction towards plastic sac along with poly bags and plastic/metal drum due to cost effectiveness and seed quality maintenance. On an average, supported and non-supported farmers retained respectively 103 kg and 100 kg of seed at household level, and sold most of their seeds to neighbouring farmers, local markets, and dealers. Wheat seed storage at household level was a profitable business to most of the respondent farmers. They could earn a reasonable net income (Tk.1127-Tk.1210) from seed storage. The farmers who stored seed in plastic/metal drum received the highest net income due to higher storage capacity, less storage cost, and higher seed price. The wheat storage program has created significant impacts in the study areas. A substantial increase was recorded in wheat area, wheat productivity, and financial benefit of the wheat farmers as a whole. Nevertheless, improved wheat seed is now available at farm level and most farmers become enthusiastic towards improved wheat cultivation because of this program. Respondent farmers did not face any critical problem during seed storage.Bangladesh J. Agril. Res. 43(2): 345-360, June 2018

AbstractClimate change will alter rainfall patterns. The effect of rainfall during seed development and maturation on wheat (Triticum aestivum L.) seed quality (ability to germinate normally; air-dry longevity in hermetic storage at 40°C with c. 15% moisture content) was investigated in field experiments (2011, 2012) by providing rain shelter or simulating additional rainfall. High ability to germinate was detected from mid seed filling until after harvest maturity. Subsequent longevity was more sensitive to stage of development. It increased progressively, reaching maximum values during maturation drying at 53–56 days after anthesis (DAA), 5–11 (2011) or 8–14 (2012) days beyond mass maturity; maximal values were maintained thereafter in 2011; longevity declined with further delay to harvest in 2012. Post-anthesis protection from rain had no major effect: in later harvests longevity was slightly greater than the control in each year, but in 2011 wetting treatments were also superior to the control. Wetting ears at all stages of development reduced longevity immediately, but considerable recovery in subsequent longevity occurred when seeds re-dried in planta for several days. The greatest damage to longevity from ear wetting occurred with treatments at about 56 DAA, with poorest recovery at 70 DAA (i.e. around harvest maturity) in absolute terms but at 56–70 DAA relative to gross damage. Hence, seed quality in a strongly dormant wheat variety was resilient to rain. Net damage was greatest from rain late in maturation. The phase of seed quality improvement in planta was dynamic with deterioration also occurring then, but with net improvement overall.

Soybean seed treatment contributes to the maintenance of seed quality, but the effect of commercial formulations and chemical products on the effectiveness of the electrical conductivity test based on electrolyte leaching has been frequently questioned. This study aimed to verify the interference of the chemical seed treatment of two soybean cultivars on the effectiveness of the electrical conductivity test in evaluating the vigor of freshly treated and stored seeds. The experimental design was completely randomized, consisting of seven seed treatments and two evaluation periods (0 and 60 days after storage), with four replications. The used seed treatments consisted of 1) fipronil + pyraclostrobin + thiophanate-methyl, 2) imidacloprid + thiodicarb + carbendazim + thiram, 3) abamectin + thiamethoxan + fludioxonil + mefenoxam + thiabendazole, 4) carbendazim + thiram, 5) fludioxonil + mefenoxam + thiabendazole, 6) carboxin + thiram, and 7) control (no treatment). The cultivars were BRS 360 RR and BRS 284, which were analyzed separately. Germination, accelerated aging, emergence, and electrical conductivity tests were carried out. No differences were detected between the control and chemical treatments performed on seeds of the two freshly treated soybean cultivars regarding germination, accelerated aging, and emergence tests. The germination test stood out after storage with the cultivar BRS 360 RR, showing the maintenance of germination potential for seeds treated with carbendazim + thiram and the control treatment. Therefore, the chemical treatment of soybean seeds interferes with the result of the electrical conductivity test. The electrical conductivity test is effective in segregating seed lots in terms of vigor level. The electrical conductivity test correlates with the other vigor tests used to identify the reduction in the physiological seed quality with storage.

Crop Establishment

Disease management is an important step in any crop establishment system. Emergence of field-seeded crops may take several weeks for many species and represents a vulnerable stage of plant growth. This paper considers various biological, chemical, and physical seed treatments for improved seed performance. The role of seed quality and cultural practices in seedling establishment also is reviewed. Multidisciplinary approaches to improving horticultural crop establishment are promising.
