皿测结果表明,三唑酮、三唑醇和井岗霉素能显著地抑制小麦纹枯病菌的生长,三唑酮、三唑醇和井岗霉素的EC_(50)分别为4.25、1.41和0.44微克/毫升。剂量反应曲线分别为:三唑酮,y=18.40+21.83 ln x;三唑醇,y=44.97+14.70 ln x;井岗霉素,y=62.00+14.53 lnx。其中y为抑菌率,x为药剂浓度。处理菌落在转移到无药PDA上后,直线生长能较快恢复,侵染力则不能在短期内恢复。加药PDA上培养的菌落和在无药PDA上复壮的菌落对小麦的侵染力均受到明显的抑制,抑制程度从22.81~100%不等。浓度高,则抑菌力强。
The results showed that triadimefon, triadimenol and Jinggangmycin significantly inhibited the growth of Rhizoctonia solani. The EC50 of triadimefon, triadimenol and Jinggangmycin were 4.25 and 1.41, respectively 0.44 μg / ml. The dose response curves were: triadimefon, y = 18.40 + 21.83 ln x; Triadimenol, y = 44.97 + 14.70 ln x; Sjogurticin, y = 62.00 + 14.53 lnx. Where y is the antibacterial rate, x is the drug concentration. After the colonies were treated for transfer to the drug-free PDA, the linear growth recovered quickly and the infectivity failed to recover in a short period of time. The colonies cultured on dosing PDA and the colonies rejuvenated on drug-free PDA were all significantly inhibited against the infectivity of wheat, and the inhibition ranged from 22.81% to 100%. High concentration, the strong antibacterial.
