BCPC Congress 2022 – Delivers an Insight Into the Future of UK Agriculture 2022年BCPC大会-洞察英国农业的未来
Q2 Agricultural and Biological Sciences Pub Date : 2022-12-01 DOI: 10.1564/v33_dec_08
This year's BCPC Congress, returned to Harrogate on 7 and 8 November, and was attended by over 130 participants. Addressing the theme of 'Providing policy and regulatory support for multi-functional UK agriculture' the speakers – some presenting to the delegates on-line – delivered informative, thought-provoking and at times controversial presentations covering a range of issues. BCPC's General Manager, Julian Westaway said he was delighted that the Congress has again attracted such positive interest. The programme enabled them to deliver a great mix of authoritative speakers. Analysing the two days, there were key themes which were repeated throughout, namely agricultural policy, land-use and food security, future pesticide regulation in the UK, current pesticide regulatory issues, possible changes to pesticide management, current and future challenges to pesticide use.
今年的BCPC大会于11月7日和8日回到哈罗盖特,有130多名与会者参加。针对“为多功能英国农业提供政策和监管支持”的主题,演讲者——一些人在网上向代表们做了演讲——提供了信息丰富、发人深省、有时颇具争议的演讲,涵盖了一系列问题。BCPC总经理Julian Westaway表示,他很高兴大会再次吸引了如此积极的兴趣。该计划使他们能够提供大量的权威演讲者。通过分析这两天的会议,我们发现会议中反复出现了一些关键主题,即农业政策、土地使用和粮食安全、英国未来的农药监管、当前的农药监管问题、农药管理可能发生的变化、农药使用当前和未来的挑战。

Chemical Control of Fleabane Resistant to 2,4-D Fleabane对2,4-D抗性的化学防治
Q2 Agricultural and Biological Sciences Pub Date : 2022-12-01 DOI: 10.1564/v33_dec_07

Conyza spp. (fleabane) are among the main weeds found globally. They have an annual life cycle and herbaceous size, high seed production, are found in different agricultural environments, such as grain crops (Photo 1). Fleabane control can be hindered by one or more of the following factors: high propagule production, wind propagation of propagules, herbicide resistance. For example, a single fleabane plant can produce more than 200,000 seeds in a year. In Brazil, there are cases of Conyza sumatrensis with multiple resistance to the herbicides chlorimuron and glyphosate, simple resistance to paraquat, in addition to cases of simple or multiple resistance to these and other herbicides (photosystem II inhibitors and synthetic auxins). Also in Paraguay, a country that borders Brazil, there is a report of a biotype with triple resistance to the herbicides paraquat, chlorimuron and glyphosate. In addition to this scenario of difficulties in control and cases of resistance, only 2.7 fleabane plants m–2 can reduce soybean productivity by 50%. These cases of fleabane resistance to herbicides make their management difficult, due to the loss of control tools. One of the main problems in this regard is resistance to 2,4-D, due to the complex rapid necrosis resistance. Rapid necrosis is an uncommon response to 2,4-D herbicide and this response is related to environmental conditions during application (temperature and light). After application of 2,4-D, necrotic symptoms occur rapidly in the leaves, in some situations within less than an hour after application. The rapid accumulation of reactive oxygen species (ROS) after application of 2,4-D causes lipid peroxidation and the production of ROS is related to the occurrence of necrosis in C. sumatrensis. Rapid necrosis resembles a programmed cell death response. However, these symptoms do not lead to plant death, with subsequent plant recovery one to two weeks after application, in addition to disrupting sequential application with burndown herbicides. Considering this setback, alternatives to be used to control fleabane iinclude the use of other synthetic auxins, such as dicamba, triclopyr, halauxifen or fluroxypyr, or even other herbicides, such as atrazine and mesotrione, which are adopted in maize cultivation or in the off-season. These herbicides can be used in the first application in a mixture with glyphosate, in which the control is complemented by the sequential application of glufosinate. These herbicides mixed with glyphosate are believed to be effective in controlling 2,4-D-resistant fleabane in the first application of pre-sowing soybean desiccation. The objective of this study was to evaluate the efficacy of glyphosate in mixtures with dicamba, triclopyr, halauxifen/diclosulam, fluroxypyr/clethodim, 2,4-D or atrazine/mesotrione, with sequential application of glufosinate, in the control of 2,4-D resistant fleabane in soybean pre-sowing.
水稻属(fleabane)是全球发现的主要杂草之一。它们有一个年度生命周期,草本植物大小,种子产量高,分布在不同的农业环境中,如粮食作物(照片1)。以下一个或多个因素可能会阻碍跳蚤的控制:繁殖体产量高、繁殖体的风力繁殖、除草剂抗性。例如,一株芭蕉一年可以产生20多万颗种子。在巴西,除了对这些除草剂和其他除草剂(光系统II抑制剂和合成生长素)具有单一或多重抗性外,还有对除草剂氯嘧磺隆和草甘膦具有多重抗性的水稻,对百草枯具有单一抗性。同样在与巴西接壤的巴拉圭,有一份报告称,一种生物类型对除草剂百草枯、氯嘧磺隆和草甘膦具有三重耐药性。除了这种难以控制和出现抗性的情况外,只有2.7株萱草m-2可以使大豆生产力降低50%。由于失去了控制工具,这些fleabane对除草剂的耐药性使其管理变得困难。这方面的主要问题之一是对2,4-D的抗性,这是由于其具有复杂的快速坏死抗性。快速坏死是对2,4-D除草剂的一种罕见反应,这种反应与施用过程中的环境条件(温度和光照)有关。施用2,4-D后,叶片迅速出现坏死症状,在某些情况下,施用后不到一小时。施用2,4-D后活性氧(ROS)的快速积累导致脂质过氧化,ROS的产生与苏门答腊C.sumatrensis坏死的发生有关。快速坏死类似于程序性细胞死亡反应。然而,这些症状不会导致植物死亡,除了干扰焚烧除草剂的连续施用外,还会在施用后一到两周内恢复植物。考虑到这一挫折,用于控制fleabane的替代品包括使用其他合成生长素,如麦草畏、三氯吡、哈劳昔芬或氟氧吡,甚至使用其他除草剂,如阿特拉津和甲基三酮,这些除草剂在玉米种植或淡季使用。这些除草剂可以在第一次施用时与草甘膦混合使用,其中通过连续施用草膦来补充对照。在大豆播种前干燥的首次应用中,这些除草剂与草甘膦混合被认为可以有效地控制耐2,4-D的fleabane。本研究的目的是评估草甘膦与麦草畏、三氯吡、哈劳昔芬/双氯舒拉姆、氟氧吡/氯托丁、2,4-D或阿特拉津/甲基三酮的混合物,以及顺次施用草膦酸盐,在大豆预播中防治2,4-D抗性fleabane的效果。

Livestock Farmers Warned Over Mycotoxin Levels in Feed Grains 畜牧业农民警惕饲料颗粒中的真菌毒素水平
Q2 Agricultural and Biological Sciences Pub Date : 2022-12-01 DOI: 10.1564/v33_dec_12
Widespread drought across Europe during the 2022 grain growing season has left livestock farmers wary as the dry spell caused higher levels of mycotoxins. The drought has increased the presence of moulds which, in turn, bumped up the mycotoxin levels in new crop grains and forages. Mycotoxins are produced by certain species of fungus and are a big concern for livestock producers as they can influence feed quality and subsequent animal health and performance. The grim news was delivered by an analysis of crops grown in 2022 and sampled in a joint effort between Alltech and SGS, a global leader in mycotoxin testing and certification. The Alltech 2022 European Harvest Analysis collected data for key feed ingredients on a regional level, and the final results indicate moderate to high levels of mycotoxin risk. Over 1,000 samples of the most common grains and forages produced and used in the European livestock industry were taken as part of the work. Samples have been collected from farms or animal feed production sites in 20 different countries, offering a representative picture of the contamination risk in all regions, with an overall moderate to high risk. Dr Radka Borutova, European technical support manager with the Alltech mycotoxin management team, said the current results look very similar to the analysis performed in 2021, with the aflatoxin issue in central and south eastern Europe dominating the headlines and creating the greatest challenge for feed and livestock producers to manage. Although this analysis gives a robust assessment of the mycotoxin risk in Europe this year until you actually test the ingredients that you are using in your business, it can be difficult to implement an effective control plan. Some main results from the analysis reported that 100% of samples contained mycotoxins, with 79% containing 2 or more. On average, each sample contained 4.5 mycotoxins with aflatoxins, type B trichothecenes, fumonisins and emerging mycotoxins the most dominant groups detected. A total of 67 corn samples exceeded aflatoxin regulatory limits for feed usage, which is a major concern for livestock farmers. Mitigating mycotoxins is a huge challenge with no universal solution. However, breakthroughs are being made all the time in mycotoxin control and prevention, mycotoxin testing and the impact of mycotoxins on livestock. For the second year running, aflatoxin contamination of corn in central and south eastern Europe is a dominant issue for feed and livestock producers to consider as they begin to purchase and use ingredients during the coming feeding season.
2022年谷物生长季节,欧洲各地普遍干旱,导致霉菌毒素水平升高,牲畜养殖户对此保持警惕。干旱增加了霉菌的存在,这反过来又增加了新作物谷物和饲料中的霉菌毒素水平。真菌毒素是由某些种类的真菌产生的,对牲畜生产者来说是一个大问题,因为它们会影响饲料质量以及随后的动物健康和生产性能。这一严峻的消息是由奥特奇和全球领先的真菌毒素检测和认证公司SGS共同对2022年种植的作物进行分析后得出的。Alltech 2022欧洲收获分析在区域层面收集了关键饲料成分的数据,最终结果表明存在中度至高度的霉菌毒素风险。欧洲畜牧业生产和使用的1000多种最常见的谷物和饲料样本被作为这项工作的一部分。从20个不同国家的农场或动物饲料生产场所收集了样本,提供了所有区域污染风险的代表性情况,总体风险为中等至高度。奥特奇霉菌毒素管理团队的欧洲技术支持经理Radka Borutova博士说,目前的结果看起来与2021年进行的分析非常相似,当时中欧和东南欧的黄曲霉毒素问题占据了头条新闻,给饲料和牲畜生产商带来了最大的管理挑战。尽管该分析给出了今年欧洲真菌毒素风险的可靠评估,直到您实际测试您在业务中使用的成分,但实施有效的控制计划可能很困难。分析的一些主要结果报告说,100%的样品含有真菌毒素,其中79%含有2种或更多。每个样本平均含有4.5种真菌毒素,其中黄曲霉毒素、B型毛霉毒素、伏马菌毒素和新发真菌毒素是检测到的最主要群体。共有67个玉米样品的黄曲霉毒素含量超过饲料使用的监管限制,这是畜牧农民的一个主要问题。减轻真菌毒素是一项巨大的挑战,没有普遍的解决办法。然而,在霉菌毒素控制和预防、霉菌毒素检测以及霉菌毒素对牲畜的影响方面一直在取得突破。在中欧和东南欧,玉米黄曲霉毒素污染连续第二年成为饲料和牲畜生产商在即将到来的饲养季节开始购买和使用原料时需要考虑的主要问题。

The Association of Applied Biology Held a Meeting to Discuss "Bringing Biocontrol and IPM to Market" 应用生物学协会召开会议讨论“将生物防治和IPM推向市场”
Q2 Agricultural and Biological Sciences Pub Date : 2022-12-01 DOI: 10.1564/v33_dec_05

Keith Walters welcomed delegates and chaired the first session on "New Solutions", aimed to attract presentations on latest developments and novel Biocontrol/IPM approaches nearing completion or recently launched. Lauren Diepenbrock (University of Florida) started the session in which 'Rebuilding of IPM in growing citrus' was described. Before Huanglongbing (HLG) in the good old days, farmers may have used an oil spray and they used spider webs between trees. HLG is a bacterial disease Liberibacter asiaticus, first detected in 2005 that caused yellow shoots, twig dieback, stunted growth, and overall tree decline with misshapen fruits. Another pest from 1998 was the Asiatic citrus psyllid (ACP – Diaphorina citri) that is the vector of Candidactus liberator, causal agent of HLB. With many natural enemies including ladybirds, lacewings, syrphids, spiders, ants and other parasitoids, but from 1998–2016, in Citrus Health Management areas, farmers used insecticides, including neonicotinoids, but although this achieved solid returns, it was not going to last and there was a need to return to IPM, by incorporating non-insecticidal management options and reduce insecticide inputs. A new tool was to apply kaolin clay to reduce psyllid infestation and increase plant health. Another new idea was to protect individual trees with Exclusion bags to prevent ACP access to trees and improve scouting for pests. While successful with young trees, more research is needed to improve the return on investment.
Keith Walters对代表们表示欢迎,并主持了关于“新解决方案”的第一届会议,旨在吸引有关最新发展和即将完成或最近启动的新型生物防治/IPM方法的介绍。Lauren Diepenbrock(佛罗里达大学)在“重建柑橘种植中的IPM”会议上发言。在黄龙冰(HLG)之前,在过去的好日子里,农民们可能使用喷油器,他们在树之间使用蜘蛛网。HLG是一种细菌性疾病亚洲Liberibacter asiaticus,于2005年首次发现,导致嫩芽发黄,枝条枯死,生长迟缓,树木整体下降,果实畸形。1998年发现的另一种害虫是亚洲柑橘木虱(ACP - Diaphorina citri),它是HLB的致病因子白弧菌(candiactus liberator)的载体。有许多天敌,包括瓢虫、草蛉、蚜虫、蜘蛛、蚂蚁和其他类寄生虫,但从1998年至2016年,在柑橘健康管理区域,农民使用杀虫剂,包括新烟碱类,尽管这取得了稳定的回报,但它不会持续,需要回归IPM,通过结合非杀虫管理方案和减少杀虫剂投入。应用高岭土是减少木虱侵害和提高植物健康的新手段。另一个新想法是用隔离袋保护每棵树,以防止ACP接近树木,并改善对害虫的侦察。虽然在幼树方面取得了成功,但还需要更多的研究来提高投资回报。

HLG is a bacterial disease Liberibacter asiaticus, first detected in 2005 that caused yellow\u0000 shoots, twig dieback, stunted growth, and overall tree decline with misshapen fruits. Another pest from 1998 was the Asiatic citrus psyllid (ACP – Diaphorina citri) that is the vector of Candidactus liberator, causal agent of HLB. With many natural enemies including ladybirds,\u0000 lacewings, syrphids, spiders, ants and other parasitoids, but from 1998–2016, in Citrus Health Management areas, farmers used insecticides, including neonicotinoids, but although this achieved solid returns, it was not going to last and there was a need to return to IPM, by incorporating\u0000 non-insecticidal management options and reduce insecticide inputs. A new tool was to apply kaolin clay to reduce psyllid infestation and increase plant health. Another new idea was to protect individual trees with Exclusion bags to prevent ACP access to trees and improve scouting for pests.\u0000 While successful with young trees, more research is needed to improve the return on investment.","PeriodicalId":19602,"journal":{"name":"Outlooks on Pest Management","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47569360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Editorial: How Precious is Our Water? 社论:我们的水有多珍贵?
Q2 Agricultural and Biological Sciences Pub Date : 2022-12-01 DOI: 10.1564/v33_dec_01
L. Copping
The world needs to stop and think about how it grows crops to supply the food we all need before it is too late and how it uses water to do this and how much water it does use. But is the world ready and willing to do this? Let us hope so.
世界需要停下来思考,在为时已晚之前,它如何种植作物来供应我们所有人所需的食物,以及它如何利用水来做到这一点,以及它确实使用了多少水。但世界准备好并愿意这样做了吗?让我们希望如此。

A Summary of the Seventh Annual Review of the BCPC's Pests and Beneficials Group BCPC有害生物和受益人小组第七次年度审查摘要
Q2 Agricultural and Biological Sciences Pub Date : 2022-10-01 DOI: 10.1564/v33_oct_05

The purpose of the Pests and Beneficials Group is to provide a forum for discussion of relevant research results and new legislation and impact on integrated pest management. The objective of this meeting was to understand better how to deliver practical IPM solutions to farmers. This starts with the policy context, followed by research that can be done and finally the delivery of tools and information to famers and the successful implementation of IPM in the field. The meeting also sought to highlight the need to integrate the thinking about the implications of combining IPM management decisions for insect, disease and weed pests and the trade-offs that may have to be made as a result. Cathryn Lambourne, Knowledge Transfer Manager from Agrifood section of the KTN (Knowledge Transfer Network), UKRI provided an account of the work of the KTN, particularly in the Agrifood sector, providing support for those seeking information, funding, and connections within the industry followed by a short outline of the principles of IPM.
有害生物和受益者小组的目的是提供一个论坛,讨论相关研究成果、新立法以及对有害生物综合管理的影响。这次会议的目的是更好地了解如何向农民提供切实可行的IPM解决方案。这首先是政策背景,然后是可以进行的研究,最后是向农民提供工具和信息,以及IPM在该领域的成功实施。会议还试图强调,需要综合考虑将害虫、疾病和杂草害虫的IPM管理决策结合起来的影响,以及由此可能需要做出的权衡。英国知识产权研究所KTN(知识转让网络)农业食品部门的知识转让经理Cathryn Lambourne介绍了KTN的工作,特别是在农业食品部门,为那些在行业内寻求信息、资金和联系的人提供了支持,然后简要概述了IPM的原则。
