我国东北地区常见除草剂药害原因分析与解决方法

我国除草剂药害发生频繁，损失严重，主要原因是除草剂使用技术落后，喷雾器械不标准及使用技术不规范。应加强农药管理。注重除草剂安全性评价，对不安全的除草剂及长残留除草剂如有替代品种取消注册登记，对无替代品种限制使用；制定喷雾器械质量标准及使用技术规范；首先系统地培训技术队伍，普及规范的化学除草技术，利用内源植物生长调节剂缓解药害。

Analyzing the causes of and solutions for crop injury by herbicides commonly used in northeast China

Herbicide-induced crop injury is common across China, causing significant yield losses. The primary reasons include improper utilization of herbicides, along with incorrect operation of substandard spray machinery. Thus, better pesticide management needs to be implemented with greater emphasis placed on evaluation of herbicide crop safety. Registration should be cancelled on long-residual herbicides for which replacements are available, and use restrictions implemented for long-residual herbicides with no suitable substitutes. Quality standards for spray machinery along with standardized criteria for its use should be enacted. Technical personnel should be systemically trained so as to normalize these standards throughout the herbicide application industry. Endogenously derived plant growth regulators should be used to mollify the effects of herbicide-induced crop injury.
