Knowledge of weed control practices and farmers’ awareness of herbicide resistance could be a basis for improving weed management programs with respect to herbicide resistance, but research on this topic is limited. This study reports current weed control practices and levels of awareness of herbicide resistance among cereal farmers of northern Greece. Face-to-face interviews were conducted with 250 cereal farmers of Evros district, based on a structured questionnaire. Most farmers (82.8%) used herbicides in cereal production, with one application per growing season. Farmers appeared divided with respect to using the same herbicide each year; the majority of the farmers (90.8%) applied crop rotation. Almost half of the farmers (47.2%) did not know what herbicide resistance is, but most farmers (75.1%) felt herbicide resistance would be a problem for them. According to their answers on nine knowledge questions about herbicide resistance, 66.8% of the farmers had good knowledge, and 33.2% had poor knowledge. Almost seven in 10 farmers (69.8%) did not consider herbicide resistance when purchasing an herbicide for use, and only 40.4% were willing to change common weed control practices to prevent herbicide resistance. Awareness of herbicide resistance did not differ by sex; poor awareness levels increased with advanced age, low education levels, and small farm size. Farmers who used chemical weed control had higher awareness levels of herbicide resistance than farmers who never used herbicides. Farmers who were keeping records of herbicide applications, those who observed low efficacy of herbicides in their field, and those who applied crop rotation had high awareness levels of herbicide resistance, whereas farmers who used the same herbicide each year had poor awareness. Findings shed light on inter-relationships between farmers’ awareness of herbicide resistance and current weed control practices that could be useful for targeted extension education.

希腊北部谷物农民的杂草控制实践和对除草剂抗性的认识

杂草控制实践的知识和农民对除草剂抗性的认识可以作为改进杂草抗性管理计划的基础，但对该主题的研究有限。本研究报告了希腊北部谷物农民当前的杂草控制实践和对除草剂抗性的认识水平。根据结构化问卷，对埃夫罗斯区的 250 名谷物农民进行了面对面访谈。大多数农民（82.8%）在谷物生产中使用除草剂，每个生长季节使用一次。农民在每年使用相同的除草剂方面似乎存在分歧；大多数农民（90.8%）实行轮作。几乎一半的农民（47.2%）不知道什么是抗除草剂，但大多数农民（75. 1%）觉得除草剂抗性对他们来说是个问题。从对9个除草剂抗性知识题的回答来看，66.8%的农户知识水平较高，33.2%的农户知识水平较差。几乎十分之七的农民（69.8%）在购买使用除草剂时没有考虑除草剂抗性，只有 40.4% 愿意改变常见的杂草控制措施以防止除草剂抗性。对除草剂抗性的认识不因性别而异；随着年龄的增长、教育水平低和农场规模变小，意识水平较差。使用化学除草剂的农民对除草剂抗性的认识水平高于从未使用除草剂的农民。记录除草剂施用记录的农民，观察到田间除草剂功效低下的农民，采用轮作的农户对除草剂的抗药性意识水平较高，而每年使用相同除草剂的农户对除草剂的抗药性意识较差。研究结果揭示了农民对除草剂抗性的认识与当前的杂草控制实践之间的相互关系，这可能有助于有针对性的推广教育。
