Description

一种杀菌剂组合物 技术领域
本发明属于农业植物保护领域，特别是涉及一种具有改进性能的杀菌组合物，具体地说是涉及一种包含苯并异噻唑啉酮类和乙嘧酚及其衍生物的杀菌组合物。

苯并异噻唑啉酮类化合物是一种新型、广谱杀菌剂，主要用于防治和治疗禾谷类作物、蔬菜、水果等多种细菌、真菌性病害。其杀菌作用机理，主要包括破坏病菌细胞核结构，使其失去心脏部位而衰竭死亡和干扰病菌细胞的新陈代谢，使其生理紊乱，最终导致死亡两个方面。在病害发生初期使用可有效保护植株不受病原物侵染，病害发生后酌情增加用药量可明显控制病菌的蔓延，从而达到保护和铲除的双重作用。
乙嘧酚(ethirimol)以及其衍生物乙嘧酚磺酸酯(bupirimate)属内吸性杂环类杀菌剂，主要用于防治苹果、草莓、西瓜、黄瓜、葡萄、温室玫瑰和草莓等作物的白粉病。其杀菌作用特点对菌丝体、分生孢子、受精丝等都有极强的杀灭效果，并能强力抑制孢子的形成，阻断孢子再侵染来源，杀菌效果全面彻底。对于已经发病的作物，能够起很好地治疗作用，能够铲除已经侵入植物体内的病菌，能够明显抑制病菌的扩展，无交互抗性。
实际的农药经验已经表明，重复且专一施用一种活性化合物来防治有害真菌在很多情况下将导致真菌菌株的快速选择性，为降低抗性真菌菌株选择性的危险性，目前通常使用不同活性化合物的混合物来防治有害真菌。通过将具有不同作用机理的活性化合物进行组合，可延缓抗性产生，降低施用量，减少防治成本。
发明内容
