    基于登记用量分析三唑类杀菌剂在中国的登记现状

    Analysis on the registration status of triazole fungicides in China based on the registered dosage

    • 摘要: 对中国农药信息网 (http://www.icama.org.cn/) 上登记的21种三唑类杀菌剂的信息进行分析,选择出单剂登记推荐有效成分用量差异大、离群高值点数多的8种杀菌剂 (三唑酮、丙环唑、三唑醇、粉唑醇、烯唑醇、戊唑醇、腈菌唑和氟环唑),分别从登记的农药剂型、作物、防治靶标等方面对其以单剂登记的推荐有效成分用量进行统计分析,从中进一步筛选出推荐有效成分用量差异大、离群高值点数较多的3种有效成分 (戊唑醇、氟环唑和丙环唑)、4种登记作物 (草坪、香蕉、香蕉树和小麦) 和3种登记防治靶标 (褐斑病、叶斑病和白粉病) 进行组合,并对目前已登记的10种“有效成分-作物-靶标”组合进行数据分析。结果发现:1) 丙环唑防治草坪褐斑病的推荐有效成分用量最高 (936.00 g/hm2),且推荐有效成分用量差异数值最大 (180.00~936.00 g/hm2);2) 氟环唑防治香蕉叶斑病的离群高值点数最多,且推荐有效成分用量差异最大 (62.50~450.00 g/hm2);3) 在防治小麦白粉病上,戊唑醇的推荐有效成分用量差异值最大 (51.60~262.50 g/hm2),且离群高值点数最多。为减少农药用量,建议在田间防治作物病害时,优先选择推荐有效成分用量较低的农药品种 (包括推荐有效成分用量更低的农药剂型和生物活性更高的农药有效成分)。另外,针对同一种农药制剂产品,建议不同厂家能统一确定合理的推荐有效成分用量。未来农药登记时将在农药最低有效剂量研究的基础上,针对不同作物的特定防治靶标提出更加科学、合理的推荐有效成分用量,为农药的合理减施提供科学依据。

       

      Abstract: In this paper, the information of 21 triazole fungicides registered on China Pesticide Registration Information Website (http://www.icama.org.cn/) were analyzed. Among them, 8 fungicides (triadimefon, propiconazole, triadimenol, flutriafol, diniconazole, tebuconazole, myclobutanil, epoxiconazole) with relatively larger recommended active ingredient dosage differences and more abnormal high value points were selected. Their formulations, crops and targets were analyzed respectively. Furthermore, three active ingredients (tebuconazole, epoxiconazole, propiconazole), four crops (lawn, banana, banana tree and wheat) and three targets (brown spot, leaf spot and powdery mildew) with relatively larger recommended active ingredient dosage differences and more abnormal high value points were selected to conduct combined analysis. Among which, a total of 10 “active ingredient-crop-target” combinations have been registered. The results showed that: 1) The maximum dosage of the active ingredient was observed when using propiconazole for the control of turf-brown spot (936.00 g/hm2) and its range of registered dosage was also the largest (180.00-936.00 g/hm2); 2) the control of banana leaf spot by epoxiconazole required the largest number of abnormal high value points, which also had the largest multiple of registered dosage (62.50-450.00 g/hm2); 3) In the control of wheat powdery mildew, the difference of the recommended active ingredient dosage of tebuconazole was the largest (51.60-262.50 g/hm2), and the number of high outliers was the largest. In order to reduce the dosage of pesticides, it is suggested that the pesticide varieties with low dosage of active ingredients (including pesticide formulations with low dosage of active ingredients and pesticide active ingredients with high bioactivity) should be prioritized for the control of crop diseases. In addition, for the same products, it is suggested that different manufacturers should determine the reasonable dosage uniformly. In the future, based on the study of the minimum effective dose of pesticides, more scientific and reasonable recommended active ingredient dosage of pesticides for specific control targets in different crops will be put forward, which will provide scientific basis for the rational reduction of pesticide application in China.
