第14届亚洲及太平洋地区杂草学术讨论会于1993年9月6～10日在澳大利亚的布里斯班召开,来自亚洲、大洋洲及美国等400余人参加了这次盛会。从会议上的报告与交流中可以看出有关除草剂方面有3个热点问题:(1)除草剂品种开发继续向着超高效方向发展;(2)杂草抗药性成为制约除草剂品种寿命的重要因素;(3)苗后除草剂使用中增效剂的应用更加普遍。 The 14th Weed Symposium in Asia and the Pacific was held in Brisbane, Australia on September 6-10, 1993. More than 400 people from Asia, Oceania and the United States attended the event. From the report and exchange at the meeting, we can see that there are three hot issues concerning herbicides: (1) the development of herbicide varieties continues to develop toward ultra-efficient; and (2) weed resistance has become an important factor restricting the life of herbicide varieties Factors; (3) the use of post-emergence herbicides synergist applications more common.
