中国化学除草问题与对策

Problems and Solutions for Chemical Weed Control in China

我国化学除草存在的问题是除草剂喷洒器械落后、除草剂药害发生频繁、长残留除草剂危害严重、农田杂草群落演替加快,难治杂草危害加大了化学除草工作难度。建议加强农药和施药器械的研制、生产、管理和使用技术的研究、普及,加强长残留除草剂科学使用和管理,加强果树、蔬菜、经济作物化学除草使用技术的研究。除草剂产品开发要适合国情,重视除草剂的安全性,促进我国化学除草的发展。

Current problems in chemical weed control in China include substandard spraying equipment, the frequent occurrence of herbicide-induced crop injury, crop damage due to long residual herbicides, rapid weed population shifts, and the increased difficulty of chemical weed control brought about by crop damage from hard-to-control species. Management of pesticides and application machinery will require improvement along with the strengthening of research on herbicide use technology and dissemination of information. Scientific use and better management of long residual herbicides is required. Development, manufacturing, management, and utilization research (with dissemination of findings) is needed for pesticide application equipment. Research on chemical weed control technology is needed for fruits, vegetables, and specialty crops. New herbicide product uses must be suitable for China, show good margins of crop safety, and promote the development of chemical weed control in the country.
