| 摘 要： | 目的]那他霉素作为抗真菌剂具有广谱、高效、安全、不易获得抗性的优点,但其在紫外光下容易降解的弱点限制了它在田间的应用,通过添加光稳定剂可提高它的光稳定性.方法]以水为药剂和光稳定剂的载体,采用抑菌圈法和盆栽法测定光稳定剂对药剂稳定性的影响.结果]紫外吸收剂UV-234、UV-531、UV-1164和光屏蔽剂SiO2有抑制那他霉素光解的作用,其中紫外吸收剂的效果优于SiO2,在一定时间内可显著抑制光解；自由基捕获剂T-123和抗氧剂1010没有任何作用；30 mg/L那他霉素分别与3种紫外吸收剂(3 g/L)混用防治番茄灰霉病的效果可达72.9％～78.1％,而单用30 g/L那他霉素的防效仅为35.2％.结论]适宜的紫外吸收剂可显著提高那他霉素的光稳定性,提高防治番茄灰霉病的效果.
