Description
技术领域
本发明涉及农药领域，尤其是涉及一种种衣剂，特别是一种含有咯菌腈、苯醚甲环唑和吡虫啉的悬浮种衣剂。
背景技术
咯菌腈为非内吸苯吡咯类悬浮种衣剂，高效广谱。对子囊菌、担子菌、半知菌等许多病原菌引起的种传和土传病害有非常好的防效。它通过抑制葡萄糖磷酰化有关的转运来抑制菌丝生长，最终导致病菌死亡。其独特的作用机制，与其它已知的杀菌剂没有交互抗性。在种子萌芽时，咯菌腈可被少量吸收，从而可以控制种子和颖果内部的病菌；同时咯菌腈在土壤中几乎不移动，因此能够一直保留在种子周围的区域，对作物根部提供长期的保护。另外咯菌腈优良的剂型使得种子包衣成膜快，不脱落。咯菌腈对作物种子安全，耐受性好，包衣种子可直接播种，在适当贮存条件下也可放至下一个播种季节播种。咯菌腈是全球为数不多获得美国环保局EPA“低风险”认证的产品之一。咯菌腈可广泛应用于多种作物的病害防治，如棉花、小麦、花生、大豆、水稻等。
苯醚甲环唑是一种广谱高效的杀菌剂，主要抑制抑制病菌细胞麦角甾醇的生物合成，从而破坏细胞膜结构与功能，主要用于果树、蔬菜、小麦、马铃薯、豆类、瓜类等作物，对蔬菜和瓜果等多种真菌性病害具有很好的保护和治疗作用。
吡虫啉是烟碱类超高效杀虫剂，具有广谱、高效、低毒、低残留，害虫不易产生抗性，对人、畜、植物和天敌安全等特点，并有触杀、胃毒和内吸等多重作用。害虫接触药剂后，中枢神经正常传导受阻，使其麻痹死亡。产品速效性好，药后1天即有较高的防效，残留期长达25天左右。药效和温度呈正相关，温度高，杀虫效果好。
在现代农业生产中，利用种衣剂对种子进行药剂处理是防止地下害虫及农作物土传、种传病害的经济简便的方法之一。种衣剂是一种用于作物或其它植物种子处理的、具有成膜特性的农药制剂，它能够在种子表面固化形成称为种衣的膜。种衣剂在土壤中吸水膨胀而不被溶解，允许种子正常发芽所需的水分和空气通过，所含的农药和种肥等物质缓慢释放，能够杀灭地下害虫、苗期害虫，具有防治苗期病害和系统性病害、提高种子发芽率、促进种苗健康生长等功效。
发明内容
本发明的目的在于提供一种含有咯菌腈、苯醚甲环唑和吡虫啉的悬浮种衣剂，用该种衣剂对种子进行包衣处理，具有杀虫杀菌的效果，能提高种子的发芽率，保证苗期作物不受病虫害的危害，且能减少药剂用量，虫病兼治，降低成本，并且无环境污染。

对上述实施例所得产品进行室内发芽率和发芽势检测及田间药效调查，步骤如下：
(1)首先，对种子进行拌种，精选饱满的种子，各个处理按照药种比为1:60，称好后放入培养皿中，盖上盖子，充分摇动，使种子包衣均匀，晾干。
(2)室内发芽率和发芽势调查，每次处理选取100粒饱满的种子，在室内进行实验。
(3)田间药效调查，选取小麦为实验对象，考察防虫效果。
结果如下：
表1.不同成分的种衣剂对水稻发芽率和发芽势的影响
| 实施例1 | 实施例2 | 实施例3 | 实施例4 | 空白对照 | |
| 发芽率(％) | 96 | 95 | 98 | 94 | 90 |
| 发芽势(％) | 95 | 91 | 94 | 93 | 92 |
从表1可以看出，本发明的种衣剂对种子包衣后，对其发芽率和发芽势无不良影响。
表2.不同成分的种衣剂防治病害效果
| 全蚀病 | 叶斑病 | 立枯病 | |
| 实施例1 | 88％ | 86％ | 87％ |
| 实施例2 | 92％ | 90％ | 91％ |
| 实施例3 | 91％ | 93％ | 92％ |
| 实施例4 | 93％ | 94％ | 94％ |
上述实验结果表明，本发明的悬浮种衣剂对病害的防治非常有效，实施例2-4的效果更加显著。
以上所述，仅是本发明的较佳实施例而已，并非对本发明作任何形式上的限制，虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明，任何熟悉本专业的技术人员，在不脱离本发明技术方案范围内，当可利用上述揭示的技术内容作出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明技术方案的范围内。
