摘要: 通过测定20 种助剂对华光霉素制剂的影响, 结果筛选到4 种对华光霉素的抑菌作用较为理想的助剂, 对西瓜枯萎病菌、棉花枯萎病菌和苹果轮纹病菌防效较高。田间试验示范结果表明, 助剂Z-7 (0. 3‰) 和华光霉素(1215Lg/ml) 的混合液对苹果叶螨的防治效果达90% 以上。

Abstract:

20 adjutants were tested for enhancing the effectiveness of Huaguangmycin against plant diseases and apple leafmites. Among them 4 adju-tants were found to be very effective in controlling Fusarium oxysporum f. sp.niveum , F. vasinfectum , Physalospora piricola and Terany chusdufour. Field tests showed that asplay preparation of Huaguangm ycin at 12. 5µg/ml with Z27
adjutant 0. 3‰ killed 90% of the leafmite.
