摘要/Abstract

摘要： 通过表面张力、接触角、沉积量和田间药效试验测定,初步探讨了加倍杀对井冈霉素防治玉米纹枯病的增效作用。结果表明,井冈霉素药液中加入加倍杀,能显著降低药液的表面张力和接触角,增加药液在玉米叶片上的沉积量,加倍杀最佳加入量为井冈霉素制剂量的15%。室内毒力测定和田间药效试验结果表明,加倍杀在离体条件下对井冈霉素抑制玉米纹枯病菌的菌丝生长无明显的增效作用,但能有效提高井冈霉素防治玉米纹枯病的田间防治效果,减少药剂用量。初步推断加倍杀对井冈霉素防治玉米纹枯病的增效机理是由于改善了药液的理化性能。

Abstract: Synergistic mechanism of Jiabeisha to Jinggangmycins against corn sheath blight was preliminarily studied.Results of physical and chemical properties showed that the Jinggangmycins solvent mixed with Jiabeisha could lower the surface tension of the solution and the contact angle on the surface of maize leaves, and increase sediment yield on the surface of maize leaves.The optimal mixed dose of Jiabeisha accounted for 15 percent of Jinggangmycins application.The results of in vitro and field experiment showed that that Jiabeisha had no obvious synergistic effect on Jinggangmycins in vitro, but could improve the control efficacy of Jinggangmycins against corn sheath blight.It could be deduced that synergistic mechanism of Jiabeisha to Jinggangmycins against corn sheath blight was that the physical and chemical properties were changed.

Key words: Jiabeisha, corn sheath blight, Jinggangmycins, synergistic effect
