摘要:
随着嘧菌酯(Azo)的广泛使用，病原菌对其产生的抗性很大程度上影响了Azo的防治效果。硒在农业领域同样备受关注，适量的硒能够促进作物生长，改善作物品质。基于此，为进一步提高Azo的防治效果，以模板法制备纳米硒(Se)，并以此为载体通过溶剂挥发法将Azo负载到Se中，制备出Azo@Se。结果表明，Azo可成功负载到Se的孔道中，并且羧甲基壳聚糖(CMCS)成功对其进行包封，Se对Azo的载药率为19.0%，CMCS@Azo@Se的载药率为143%。释放试验表明，CMCS@Azo@Se对Azo的释放呈现明显的碱响应特性。Azo@Se和CMCS@Azo@Se在离体条件下对番茄晚疫病菌表现出了良好且稳定的抑制作用。喷施CMCS@Azo@Se能促进番茄植株的生长和光合作用，并不会对番茄植株产生负面影响，表明其对番茄植株具有较好的安全性。本研究所制备的CMCS@Azo@Se具有可控释放特性，能够有效抑制番茄晚疫病菌，并对番茄植株的生长具有一定的促进作用。本研究为Azo纳米农药新制剂的开发提供了理论基础，为减药增效控害提供了新的途径。
