Abstract Spreading dogbane is a creeping herbaceous perennial weed in lowbush blueberry. Management is limited primarily to spot applications of dicamba, though recent herbicide registrations facilitate the evaluation of new broadcast and spot herbicide applications. The objectives of this research were to determine (1) the effect of sequential postemergence (POST) mesotrione application interval on spreading dogbane, (2) the effect of sequential POST mesotrione and foramsulfuron applications on spreading dogbane, (3) the effect of POST herbicide tank mixtures on spreading dogbane, (4) the effect of summer and fall spot herbicide applications on spreading dogbane, and (5) the effect of spot applications of dicamba tank mixtures with sulfonylurea herbicides on spreading dogbane. Broadcast mesotrione (144 g a.i. ha−1) and foramsulfuron (35 g a.i. ha−1) applications did not control spreading dogbane. Control was not improved by sequential applications of either herbicide. Broadcast mesotrione + foramsulfuron applications reduced non-bearing-year density and may be more effective than either herbicide applied alone. Broadcast flazasulfuron applications reduced non-bearing-year shoot density and flazasulfuron + foramsulfuron applications reduced non-bearing-year and bearing-year shoot densities. Summer spot applications of foramsulfuron and flazasulfuron caused 70% injury to spreading dogbane but did not reduce shoot density, and dicamba continues to be the most effective spot herbicide treatment. Fall spot applications did not control spreading dogbane due to early senescence of spreading dogbane shoots. Spot applications of dicamba at 0.96 or 1.92 g a.e. L water−1 provided equivalent spreading dogbane control and efficacy was not improved by tank mixture with foramsulfuron, flazasulfuron, or nicosulfuron + rimsulfuron.
摘要山茱萸是低灌木蓝莓中的一种多年生匍匐草本杂草。管理主要限于麦草畏的现场应用,尽管最近的除草剂注册有助于评估新的广播和现场除草剂应用。本研究的目的是确定(1)顺序羽化后(POST)中三酮施用间隔对施用毒麻的影响,(2)顺序施用POST中三酮和氟虫灵对施用毒草的影响,(4)夏秋两季点用除草剂对布麻的影响,以及(5)麦草畏与磺酰脲类除草剂混合罐的点用对布麻影响。施用广播中三酮(144 g a.i.ha−1)和氟虫磺隆(35 g a.i.ha−1)并不能控制其传播。连续施用两种除草剂都没有改善控制。广播中三酮+杀草灵降低了非生育年密度,可能比单独使用任何一种除草剂都更有效。广播使用flazasulfuron降低了非承载年的枝条密度,flazasul磺ron+foramsulfuron应用降低了非承重年和承载年的树干密度。在夏季现场施用福莫磺隆和flazasulfuron对传播的毒麻造成70%的伤害,但并没有降低芽密度,麦草畏仍然是最有效的现场除草剂处理方法。秋斑施用并不能控制施用罗布麻,因为施用罗布草的枝条衰老较早。在0.96或1.92 g a.e.L水−1的条件下,现场施用麦草畏可提供同等的布麻控制效果,且与福莫磺隆、阿磺隆或烟嘧磺隆+林磺隆的罐式混合物并未提高药效。

Abstract Donalda, a hard red spring wheat (Triticum aestivum L.), was developed at the University of Alberta, Edmonton, Canada. It is an awned, hollow-stemmed cultivar with high yield potential, short in stature with good lodging tolerance. During the 3 years of testing in the Western Bread Wheat Registration tests during 2018–2020, Donalda yielded 4.3% higher than Carberry and displayed similar physiological maturity. Additional features of Donalda that paralleled the performance of Carberry included plant height, tolerance to lodging, and quality parameters related to test weight, grain weight, and grain protein content. Overall, during the 3 years of testing, Donalda was rated “resistant” to the prevalent races of leaf, stem, and stripe rusts, “moderately susceptible” to common bunt and “intermediate” to Fusarium head blight. Three years of the end-use quality evaluation indicated that Donalda met the quality guidelines for the Canada Western Red Spring wheat market class. Résumé La variété de blé roux vitreux de printemps (Triticum aestivum L.) Donalda a été créée à l’Université de l’Alberta, à Edmonton (Canada).

Au cours des trois années qu’ont duré les essais d’homologation du blé panifiable de l’Ouest (de 2018 à 2020), Donalda a enregistré un rendement de 4,3 % plus élevé que celui de Carberry à une maturité physiologique analogue. Parmi les autres particularités de Donalda correspondant à celles de Carberry, mentionnons la taille du plant, la tolérance à la verse et les paramètres qualitatifs (poids spécifique, poids du grain et teneur en protéines du grain). Dans l’ensemble, au cours des trois années d’essai, la variété Donalda a été qualifiée de « résistante » aux races prévalentes de la rouille des feuilles, de la rouille de la tige et de la rouille jaune, de « modérément sensible » à la carie et de « moyennement résistante » à la fusariose de l’épi.

Abstract The Peace River region is one of the northern agricultural frontiers in Canada, undergoing farmland expansion as well as intensification with input-intensive industrial agriculture. The cropping systems evolved with the rotations between annual grain and perennial forage crops as a prudent adaptation to fragile, crust-forming, runoff-prone, poorly developed, platy-structured acidic Luvisolic soils. In recent years, there is a decline in the acreage of perennial forage seed crops leading to simplified low-diversity cropping systems with heavy reliance on external inputs. The production systems have been prone to the rapid evolution of herbicide-resistant weeds, and outbreaks of crop diseases and insect pests in the face of global warming. A number of studies conducted in the Peace River region and other parts of North America have shown multiple benefits of integrating perennial forage crops in the cropping systems. By virtue of high root-to-shoot ratio and perennial growth, forage seed crops can provide multiple ecological services in the fragile Luvisolic soil through increased soil organic matter, carbon sequestration, soil biological diversity, soil structural improvement, nutrient mobilization, crop protection and environmental health, thereby creating conducive effects to the resilient performance of the cropping systems. This review discusses the merits of crop rotations in general and those of perennial forage seed crops in particular in the face of changing climate, with special reference to studies conducted in the Prairies and Peace region of western Canada. Research opportunities are highlighted to elucidate multidimensional ecosystem services from diversified cropping sequences integrating perennial forage seed crops.

和平河地区是加拿大北部的农业边界之一,随着投入密集型工业农业的发展,该地区正在经历农田扩张和集约化。随着一年生粮食作物和多年生饲料作物的轮作,种植制度逐渐演变为对脆弱、结皮、易径流、发育不良、板状结构的酸性土壤的审慎适应。近年来,多年生饲草种子作物的种植面积减少,导致种植系统简化,低多样性,严重依赖外部投入。面对全球变暖,生产系统容易出现抗除草剂杂草的快速进化和作物病虫害的爆发。在皮斯河地区和北美其他地区进行的一些研究表明,将多年生饲料作物纳入种植系统有多种好处。草料种子作物凭借其较高的根冠比和多年生长势,可以通过增加土壤有机质、固碳、土壤生物多样性、改善土壤结构、养分动员、作物保护和环境健康等方式,在脆弱的鲁滨湖土壤中提供多重生态服务,从而对种植系统的抗灾性能产生有利影响。这篇综述讨论了作物轮作的优点,特别是多年生饲草种子作物在面对气候变化时的优点,特别参考了在加拿大西部草原和和平地区进行的研究。强调了多年生饲草种子作物多样化种植序列的多维生态系统服务的研究机会。在加拿大,《世界和平协定》、《世界农业公约》和《世界农业公约》。Les terres res res ables continuentde s ' ys。“文化系统”(system - culture)和“谨慎系统”(prudence - voulu qu 'on)采用了“管理系统”(assolements)和“管理系统”(plantes)。“管理系统”(plantes)和“管理系统”(plantes)都采用了“管理系统”(assolements),“管理系统”(fragililit du sol”,“管理系统”,“管理系统”,“管理系统”,“管理系统”,“管理系统”)。从几排cependant, assiste有一个减少de la superficie consacree de粮食de la生产植物园饰带活泼的et l 'avenement de系统culturaux +简便性,减去多样化,这reposent lourdement苏尔l 'apport走读生d 'intrants。由于气候变暖,对作物有利的作物种类增多,对除草剂有害,对疾病有害,对害虫有害。将不同的交换条件交换成不同的交换条件交换成不同的交换条件交换成不同的交换条件交换成不同的交换条件交换成不同的交换条件交换成不同的交换条件交换成不同的交换条件交换成不同的交换条件交换成不同的交换条件交换成不同的交换条件。在我们的和谐生活中,我们的生活方式是:在我们的生活中,我们的生活方式是:我们的生活方式是:我们的生活方式是:我们的生活方式是:我们的生活方式是:我们的生活方式是:我们的生活方式是:我们的生活方式是:我们的生活方式是:我们的生活方式是:我们的生活方式是:我们的生活方式是:我们的生活方式是:我们的生活方式是:我们的生活方式是:我们的生活方式是:我们的生活方式是:我们的生活方式是:我们的生活方式是:我们的生活方式是:我们的生活方式是:Les导演examinent优点之一de l 'assolement一般et des assolements德文化grainiere de植物园饰带en particulier脸盟换向机构的避暑,en faisant specialement参考辅助练习曲意识到在草原et de la la地区和平河,在l财产的法裔加拿大人。它标志着可能性变少了,例如,研究变少了,传播变少了,服务变少了,多维度变少了,例如,传播变多了,传播变多了,传播变多了,传播变多了,传播变多了,传播变多了,传播变少了,传播变少了,传播变少了,传播变少了,传播变少了。[贸易协定]

Abstract The objective of this study was to reveal the potential of using Fourier transform mid-infrared (FTIR) and near infrared (NIR) spectroscopy as tools for the determination of indigestible neutral (NDF) fraction (iNDF) of whole-crop barley silage. A total of 48 whole-crop barley silage samples collected from 48 different farms in Western Canada were analyzed for iNDF. Reference values were matched with NIR and FTIR spectra. Spectral data processing (pretreatments) included first derivative, standard normal variate, multiplicative scattering correction, second derivative, and orthogonal signal correction. Prediction equations were obtained from each model using an external validation set. The coefficient of determination for the external validation of iNDF was 0.62 for FTIR and 0.41 for NIR, while the corresponding ratio performance deviation was 1.69 and 1.38 for FTIR and NIR, respectively. Results from this research showed the high potential of applying infrared molecular spectroscopy for the examination of forage plant fiber digestibility. More studies are needed to improve the accuracy and performance of FTIR and NIR spectroscopies in predicting the iNDF of whole-crop barley silage samples.

More studies are needed to improve the accuracy and performance of FTIR and NIR spectroscopies in predicting the iNDF of whole-crop barley silage samples.","PeriodicalId":9530,"journal":{"name":"Canadian Journal of Plant Science","volume":"102 1","pages":"1130 - 1138"},"PeriodicalIF":1.2,"publicationDate":"2022-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42607773","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
Abstract Camera-guided narrow (15 cm)-row, inter-row cultivation, with or without the Einböck rotary weeder, reduced weed growth but had lower yield than herbicide-treated dry beans. In wide rows (60 cm), camera guidance improved finger weeder performance and mechanically weeded dry bean yields were similar to the herbicide treatment.

Abstract The effect of irrigation on soft scald (SS) disorder in Ambrosia™ apples was surveyed over 4 years in various orchards in Cawston, BC which is located in a valley having a semiarid eco-zone. The observations were further validated by manipulating irrigation programs in a series of experiments in three commercial orchards. Adequate irrigation (AI) was defined as the amount of water application required to maintain sustainable production as defined in the provincial irrigation guide, while deficit irrigation (DI) reduced irrigation to less than 40% of AI at the same site. Records from the survey study indicated that SS incidence was negatively correlated with the amount of watering (r = −0.9). The validation study confirmed that correlation at three different commercial sites. These results suggest that intensive water deficit can cause fruit to be susceptible to SS and that adequate watering during fruit expansion and late season exerts a mitigating effect on SS in Ambrosia™ apples grown in a dry climate region. They also suggest that conducting DI prior to midsummer does not irrevocably cause SS susceptibility in this apple.

Abstract AAC Westlock, an awned hard red spring wheat (Triticum aestivum L.) cultivar, combines high grain yield and good agronomic characteristics with excellent resistance to leaf, stripe, and stem rust (including variants of Ug99), Fusarium head blight (FHB), and common bunt. Based on 40 station-years of registration trial data from 2018 to 2020, the grain yield of AAC Westlock was 1% higher than AAC Foray and 7% over AAC Penhold. AAC Westlock was significantly shorter than AAC Foray, had straw strength similar to AAC Penhold, and maturity similar to AAC Foray. AAC Westlock had similar test weight and protein concentration but lower thousand kernel weight as compared to AAC Foray. AAC Westlock had milling and baking quality suitable for grades of the Canada Prairie Spring Red wheat market class.
