摘　　要：为筛选高效安全、防效优异的化学药剂及施药方式,在赤霉病防治关键时期,选择市面上常用的小麦赤霉病防治药剂,采用两种施药方式开展小麦赤霉病防效对比试验。结果表明,在防治药剂选择上,可选用20%氟唑菌酰羟胺SC 750 mL/hm^(2)+25%丙环唑EC 600 mL/hm^(2)、40%丙硫菌唑·戊唑醇SC 600 mL/hm^(2)、30%丙硫菌唑OF 900 mL/hm^(2)+43%戊唑醇SC 600 mL/hm^(2)、30%肟菌·戊唑醇SC 600 mL/hm^(2)或70%甲基硫菌灵WP1500 g/hm^(2)中的任意一种进行防治。在施药器械选择上,单论施药效果时,采用背负式电动喷雾器的施药效果优于多旋翼植保无人机施药;而考虑人工成本、作业效率和防治时效等多方面因素,应依据自身实际情况酌情选择。本研究为科学防控小麦赤霉病提供参考。In order to screen for highly effective,safe,and excellent chemical agents and application methods,during the critical period for the control of scab,commonly used wheat scab control agents were selected from the market,and a comparative trial of wheat scab control efficacy was conducted using two application methods.The results showed that for the selection of control agents,any one of the following could be used:20%fluxapyroxad SC 750 mL/hm^(2)+25%propiconazole EC 600 mL/hm^(2),40%prothioconazole·tebuconazole SC 600 mL/hm^(2),30%prothioconazole OF 900 mL/hm^(2)+43%tebuconazole SC 600 mL/hm^(2),30%dimethomorph·tebuconazole SC 600 mL/hm^(2),or 70%thiophanate-methyl WP 1500 g/hm2.In terms of application equipment,when considering only the application effect,the efficacy of using a knapsack electric sprayer was superior to that of using a multi-rotor plant protection drone.However,taking into account factors such as labor,operational efficiency,and timing of control,appropriate method could be choosed based on its actual circumstances.The purpose was to provide a reference for the scientific prevention and control of wheat scab.
