| 中文摘要: |
| 三唑类杀菌剂（triazole fungicide, TFs）是一类广谱、高效、低残留、长效、内吸传导性好, 同时具有保护和治疗作用的新型杀菌剂，对真菌性病害有较好的防控效果, 在作物病害防治上被广泛应用。三唑类杀菌剂在防治水稻中、后期真菌性病害上取得了极好的防效, 是应用量较大的杀菌剂之一。但由于三唑类杀菌剂使用不当, 在生产上造成了大量的药害实例, 导致水稻减产或绝收, 同时引起了一些社会问题, 需要引起高度重视。本文在作者多年的调查和研究基础上结合相关文献资料, 阐述了三唑类杀菌剂的分类、使用方法、作用机制, 对水稻产生药害的原因、症状表现和机理, 使用三唑类杀菌剂时避免发生药害的措施及药害发生后的补救方法。 |
| 英文摘要: |
| Triazole fungicides (TFs) are extensively applied in crops fungal diseases management due to their distinctive advantages of high efficiency, broad spectrum, low residue, long persistent effect, good uptake and translocation, having the functions of protection and treatment, and showed very good control efficacies to multiple fungal diseases of different crops. Since a wonderful control efficacy achieved by using TFs to control rice fungal diseases at middle and late rice growing stages, the TFs has become one of the fungicides with large application amounts in rice production. However, a lot of cases of phytotoxicity on rice caused by TFs often occurred due to misemploy and lead to yield reduction or even total rice failure, and bring about some social problems, which should be paid more attention. In this paper, according to the author’s years of investigation and research results, combined with relevant literature, the classification, application methods, action mechanism of TFs as well as how to avoid the occurrence of phytotoxicity caused by TFs, and remedial action taken after phytotoxicity occurred were elaborated. |
