据室内测定结果,特谱唑具有很强的内吸传导性能,用灌土法施药的效果可与叶面喷雾法相比拟,但基本上是向上传导。此药具有很强的治疗和铲除作用,在病菌潜育期施药,可控制到不发病,最多只显退绿斑;在退绿期施药,可使病菌夏孢子堆变成褐色小点,孢子粉极少,但对夏孢子的萌发影响则弱。此药剂比三唑酮毒力强,其毒力指数(三唑酮为100)都在900以上,即达到 EC_(50)和 EC_(95)所需的剂量,前者只需后者的11%以下,特别是保护作用突出。据田间试验结果,此药剂的用药量比三唑酮少,如控制条锈病为害所需的剂量只要三唑酮的三分之一。防治条锈病的用药量一般以45—47g/ha(有效成分)为合适;用药期以病叶率5%—10%、小麦处于旗叶伸长期为宜;施药次数以上述的合适剂量和适期喷施1次即可控制整个成株期条锈病为害,收到最佳的经济效益。
According to the indoor determination results, Tetaazole has a strong internal conductivity. The effect of soil irrigation method can be compared with the foliar spray method, but it is basically upward conduction. The drug has a strong effect of treatment and elimination of pesticides in the gut incubation period, can control the disease does not occur, up to only retreat green spots; in the back green period of application, the bacteria can make summer spores brown spots , Few spore powder, but the germination of uredospores is weak. This drug is more virulent than triadimefon and its virulence index (triadimefon 100) is above 900, ie the dose required for EC 50 and EC 95. The former requires only 11% of the latter, In the following, the protective effect is particularly prominent. According to the results of field trials, the dosage of this agent is less than that of triadimefon, and the dosage required for controlling stripe rust is only one third of that of triadimefon. The dosage of the control stripe rust is generally 45-47g / ha (active ingredient) is appropriate; the duration of the disease with the leaf rate of 5% -10%, wheat flag leaf elongation is appropriate; the number of doses to the above appropriate dosage and Spraying 1 can control the entire adult stripe rust damage, receive the best economic benefits.
