| 摘 要： | 为评价有机硅助剂对10种杀菌剂防治鸡蛋花锈病的增效作用,以表面张力、扩展直径、最大持留量、田间防效为评价指标,测定添加0.1%有机硅助剂对10种杀菌剂1 000倍液物理性状及田间防效的影响。结果表明,有机硅助剂能显著降低药液表面张力,增大扩展直径,提高药液持留量和防治效果。添加助剂后,药剂表面张力由34.67～66.47 mN/m降低至16.80～22.73 mN/m;扩展直径由2.09～2.56 mm增大至3.49～5.90 mm;持留量由1.43～2.88 mg/cm~2增大至1.94～4.35 mg/cm~2;在相等药剂用量下,有机硅助剂可使杀菌剂田间防效提高16.95%～36.01%。有机硅助剂通过降低药液表面张力,增加扩展直径,提高药液持留量,提高杀菌剂对鸡蛋花锈病的防治效果。

| Abstract: | This paper aims to evaluate the synergistic effect of silicone additives on the control of Coleosporium plumierae by 10 fungicides. The effect of physical properties and field control efficacy of 1 000 times of 10 fungicides with adding 0.1% silicone additives were determined by surface tension, expanded diameter, maximum retention and field investigation. The results indicated that the silicone adjuvants can significantly reduce the surface tension, and increase the expansion diameter, retention and field control effect. After adding 0.1% silicone adjuvants, surface tension reduced from 34.67-66.47 mN/m to 16.80-22.73 mN/m, expanded diameter increased from 2.09-2.56 mm to 3.49-5.90 mm, and maximum retention increased from 1.43-2.88 mg/cm2 to 1.94-4.35 mg/cm2. Under the same dosage, the silicone additive can increase the field efficacy of the fungicide by 16.95%-36.01%.The silicone additives improved the control effect of the fungicides on C.plumierae by reducing the surface tension, and increasing the expanded diameter and the retention. |
