| 摘 要： | 特谱唑对小麦白粉病效果优异，用药量低，持效期长，内吸传导性能强，使用安全，而且比目前常用的高效药剂粉锈宁效果更好，剂量更少。温室测定结果表明，特谱唑对白粉病菌的毒力和粉锈宁更强，其ＥＣ５０的毒力指数（以粉锈宁为１００），治疗作用的为５７３，保护作用的为２０９６；具有较强的内吸向上传导性能，采用喷雾法，在施药后长成的第１叶片（即第２叶）可保持很高的药效，而长成的第２叶片的效果则明显下降。田间试验和示

| Abstract: | Diniconazole has been proven to be an ideal fungicide for control of powdery mildew of wheat with following characteristics; low applying dosage, long-term persistence, strong systemicity, safety in use. Practical use of Diniconazole was significant for controlling disease epidemic, improving the level of chemical control, solving the problem of using Triadimefon as a single fungicide to control powdery mildew.
The results in greenhouse experiment showed that Diniconazole had strong toxicity to powdery mildew of wheat, the toxicity index was 573 for cure effect (where Triadimefon was 100)and 2096 for protective effect respectively, it also had good upward conductivity. Using spraying method indicated that the first grown leaf (after treatment) possess higher efficiency than that of the second grown leaf.
According to results of failed trails, the dosage for controlling was 45 - 60(From 30 - 90)g/ha that equaled to 40% dosage of Triadimefon and the suitable time of application was the period of 20% of stem-infected at flag leaf extending. Spraying just on time with the dosage and at the period above-mentioned could give best economic effect in controlling powdery mildew within the whole adult stage of wheat. Diniconazole showed a strong function of curing eradicating powdery mildew of wheat. |
