| 摘 要： | 以杂草种子萌发和幼苗生长受阻为指标,测定了玉米弯孢叶斑病菌毒素的除草活性.结果表明:毒素对马唐种子的萌发有明显的抑制作用,抑制率可达100%,但对稗草、狗尾草种子萌发的抑制作用较小.在供试植物出苗3 d后喷施毒素,发现对马唐幼苗有致萎活性,但对出苗7 d的幼苗没有作用;对稗草、狗尾草幼苗无毒杀作用.安全性试验结果表明:...

| Abstract: | The herbicidal activity of Curvularia lunata toxin was assayed and indicated by inhibition to seed germination and seeding growth of weeds.The results show that seed germination of Digitaria sanguinalis weeds were restrained by the toxin to 100%.But seed germination of Echinochloa crusgali and Setaria viridis weeds were restrained lightly.When the toxin was sprayed on seedling after growing for 3 d,the D.sanguinalis seedling growth was inhibited,but the toxin had no effect on seedling for growing for 7 d.Th... |
