*** 9801183 Bryant This SBIR Phase II project will continue the Phase I effort that investigated the use of microencapsulated water and phase change materials (PCM) microcapsules to improve biological herbicides (mycoherbicides) and offer a safe, host-specific, affordable alternative to chemical herbicides. The Phase I project successfully addressed the potential of regulating both the temperature and moisture (extending dew period) on a plant leaf surface (phyllosphere), both vital to the effectiveness of mycoherbicides. The topics to be studied in Phase II include, but are not limited to: (a) optimization of the microPCM type and concentration, (b) optimization of the application and concentration of the water microcapsules, (c) investigation of the optimum types of application systems, including spraying equipment and surfactants, (d) measurement of leaf surface temperature and moisture in response to microencapsulated materials and the relation of this to effectiveness, (e) performing field test(s) with the microencapsulated materials and the target mycoherbicide, and (f) expanding the technology to additional candidate mycoherbicides. At the end of the proposed Phase II effort, it is anticipated that the microencapsulated materials will be characterized to the point where commercial applicability in the agricultural arena can be confidently undertaken for rapid development with our Phase III sponsors. Many promising mycoherbicides have not been developed because of critical environmental conditions in the field. Successful development of the microencapsulated materials would significantly improve existing mycoherbicides, renew the development of previously abandoned mycoherbicides, and create broad applications in agriculture and environmental systems in the herbicide industry, which currently has annual sales over of 7 billion dollars. ***

* 9801183 Bryant该SBIR第二阶段项目将继续第一阶段的工作，即研究使用微胶囊化水和相变材料（PCM）微胶囊来改善生物除草剂（真菌除草剂），并提供一种安全的，针对宿主的，负担得起的化学除草剂替代品。 第一阶段项目成功地解决了调节植物叶面（叶圈）温度和湿度（延长露期）的潜力，这两个方面对真菌除草剂的有效性至关重要。第二阶段的研究课题包括但不限于：（a）微PCM类型和浓度的优化，（B）水微胶囊的施用和浓度的优化，（c）施用系统的最佳类型的研究，包括喷雾设备和表面活性剂，（d）测量叶面温度和湿度对微胶囊化材料的反应及其与效力的关系，（e）用微胶囊化材料和目标真菌除草剂进行田间试验，和（f）将该技术扩展到另外的候选真菌除草剂。 在拟议的第二阶段工作结束时，预计微胶囊化材料的特征将达到在农业竞技场中的商业适用性可以放心地进行的程度，以便与我们的第三阶段赞助商一起快速开发。 由于田间环境条件的限制，许多有前途的真菌除草剂尚未开发。微胶囊材料的成功开发将显着改善现有的真菌除草剂，重新开发以前被遗弃的真菌除草剂，并在除草剂行业的农业和环境系统中创造广泛的应用，目前年销售额超过70亿美元。 ***
