项目摘要

Terrestrial molluscs (slugs, snails) feed on a wide range of crops, causing considerable crop losses worldwide. They can devastate crops in a short period of time. Furthermore, feeding damage increases crop susceptibility to pathogens. Both are heavily attacked by slugs. It is estimated that the total annual cost to the UK industry from not controlling slugs in arable crops is over £100 million. Metaldehyde was the main pesticide used to control slugs in arable crops in the UK. It is often detected above the drinking water standard for pesticides. The withdrawal of metaldehyde and several other molluscicides has promoted an urgent search for safe alternatives. An essential oil from anisum seeds shows promise as a benign, sustainable molluscicide. This project focuses on: (1) recovery of the bioactive fraction of oil extracted using an inexpensive microwave-based method and (2) evaluating different formulations of the bioactive fraction. At least two formulations will be evaluated for delivery in drip irrigation, conventional sprayers and drilled during seed sowing or planting. Particular attention will be given to encapsulation of the AEO in inexpensive, proven matrices such as alginate, chitosan and cyclodextrin. Initial trials will be conducted in glasshouse studies with the optimised formulations and carefully selected controls being tested in experimental field trials, conducted on two important arable crops (oilseed rape, wheat). The commercial potential of the products for use as contact molluscicides, repellents and antifeedants will be evaluated by the industry partner, Crop IQ Technology, in field trials which determine optimum application rates and frequency of application. Development of innovative molluscicides will be of immense benefit to growers in both the agricultural and horticultural sectors. Unlike current products, AEO is short lived, therefore, there should be no residues but this will be verified by GC-MS analysis of plant tissue and produce. This six month study will provide CropIQ the opportunity to determine if the formulations need improvement and for development of business plan with a clear route to market.
陆生软体动物(蛞蝓、蜗牛)以多种农作物为食,在全世界造成相当大的农作物损失。它们可以在短时间内摧毁农作物。此外,取食损害增加了作物对病原体的易感性。两者都受到蛞蝓的严重攻击。据估计,英国工业每年因不控制可耕地作物中的蛞蝓而造成的总成本超过1亿英镑。在英国,三聚乙醛是用于控制农作物中蛞蝓的主要杀虫剂。它经常被检测到高于农药的饮用水标准。四聚乙醛和其他几种杀螺剂的退出促使人们紧急寻找安全的替代品。一种来自茴香种子的精油有望成为一种良性、可持续的灭螺剂。该项目的重点是:(1)回收使用廉价的基于微波的方法提取的油的生物活性级分,和(2)评价生物活性级分的不同制剂。将评价至少两种制剂在滴灌、常规喷雾器和播种或种植期间钻孔中的递送。将特别注意将AEO包封在廉价的、经过验证的基质中,如藻酸盐、壳聚糖和环糊精。初步试验将在温室研究中进行,优化的配方和精心选择的对照品将在两种重要的可耕地作物(油菜和小麦)上进行试验性田间试验。这些产品用作接触性杀软体动物剂、驱避剂和拒食剂的商业潜力将由行业合作伙伴Crop IQ Technology在田间试验中进行评估,以确定最佳施用率和施用频率。创新性杀螺剂的开发将对农业和园艺部门的种植者产生巨大的利益。与目前的产品不同,AEO的寿命很短,因此应该没有残留物,但这将通过植物组织和产品的GC-MS分析进行验证。这项为期六个月的研究将为CropIQ提供一个机会,以确定配方是否需要改进,并制定商业计划,明确市场路线。
