Description
技术领域
本发明属于农药制剂领域,具体涉及一种氯虫苯甲酰胺、丙硫菌唑和精甲霜灵种子处理悬浮剂及其应用。
背景技术
花生是重要的油脂及食品加工原料,也是我国出口创汇重要的油料作物和经济作物。目前,花生产区由于连年种植,导致土传病虫害日益加重,严重制约了花生产业的健康发展,其中地下害虫蛴螬以及根腐病是花生上的主要病虫害,严重影响花生的产量和品质,一般减产20%-30%,严重的可减产60%以上,花生地下害虫的防治及根腐病等病害的预防是困扰广大花生种植户的难题。因此筛选研制出防治花生蛴螬地下害虫、预防花生根腐病的新型药剂迫在眉睫。
氯虫苯甲酰胺属于酰胺类新型内吸杀虫剂,其作用机理是激活害虫的鱼尼丁受体,释放细胞内储存的钙离子,引起肌肉调节衰弱、麻痹直至最后害虫死亡。胃毒为主,兼具触杀。丙硫菌唑为***硫酮类杀菌剂,属甾醇脱甲基化(麦角甾醇生物合成)抑制剂。精甲霜灵能透过种皮,随着种子的萌发和生长,可内吸传导到植株的各个部位。用于种子处理,可防治由低等真菌引起的多种种传和土传病害。
CN112970765A公开了一种防治病虫害的三元复配拌种剂,该三元复配拌种剂包括有效成分A、B、C,所述A为丙硫菌唑,所述B为嘧菌酯、噁霉灵、精甲霜灵、甲霜灵、氟唑环菌胺、咯菌腈中的一种,所述C为噻虫嗪、呋虫胺、噻虫胺、氟啶虫酰胺、溴氰虫酰胺、氯虫苯甲酰胺、四氯虫酰胺中的一种;该专利文献中仅仅泛泛公开了氯虫苯甲酰胺、丙硫菌唑和精甲霜灵可以组合使用,并没有公开具体的三种成分组合使用的实施例。CN106342822A公开了一种含有咯菌腈和丙硫菌唑及氯虫苯甲酰胺的组合物,其特征在于:有效成分咯菌腈,丙硫菌唑,氯虫苯甲酰胺的质量比例为0.5-10:0.5-10:1-20;该专利公开了氯虫苯甲酰胺、咯菌腈和丙硫菌唑组合使用,没有公开氯虫苯甲酰胺、丙硫菌唑和精甲霜灵组合。现有技术中将三种成分复配使用的相关研究报导较少,更没有对氯虫苯甲酰胺、丙硫菌唑和精甲霜灵种子处理悬浮剂的相关研究报导。
种子处理悬浮剂是指用水直接稀释后用于种子处理的液体制剂。种子处理悬浮剂以水为基质因此对生产者、使用者安全环境友好符合当今农药制剂发展的要求。本发明针对氯虫苯甲酰胺、丙硫菌唑和精甲霜灵种子处理悬浮剂进行相关研究。

参考 GB/T17768-1999 悬浮种衣剂产品标准,进行检测 pH、黏度、悬浮率、及低温与热贮稳定性。由表1可知,30%氯虫苯甲酰胺·丙硫菌唑·精甲霜灵种子处理悬浮剂具有优异的制剂性能,活性成分的悬浮率均为90%以上,黏附性能均大于90%、并且均满足冷贮稳定性、热贮稳定性的要求。特别是FS-1配方种,与其他配方相比,润湿分散剂选为TERSPERSE2700、MorwetD-390 和Dispersol BB4 组合可以显著提升种子处理悬浮剂的悬浮性能和附着性能。
表1:质量控制指标测试
实施例3: 30%氯虫苯甲酰胺·丙硫菌唑·精甲霜灵种子处理悬浮剂对花生蛴螬和根腐病的田间防效
试验药剂:FS-1至FS-7;将FS制剂按400 g/100kg种子用量并且按照药液种子比1﹕50(w/w)进行稀释,然后进行拌种处理。
试验方法:选取病虫害严重地块(属于沙质土壤,连年种植花生)进行试验。设置药剂处理7个,并以清水处理为空白对照组。种植方式:人工起垄,垄宽80cm,垄高20cm,单垄双行开穴,穴距20cm,每穴2粒种子,人工点播,每处理3个重复,小区面积30m2,各小区随机区组排列。
调查方法:病害调查:花生齐苗后60d,调查病情;虫害调查:花生收获期调查,每小区棋盘式8点取样,每点5穴,调查花生蛴螬活虫数,计算防效。
根腐病分级方法:0级,无病;1级,根系稍有变色,变色根系占全部根系的10.0%以下,植株不萎蔫;3级,根系明显变褐,变色根系占全部根系的10.1%-30.0%,植株开始萎蔫;5级,变色根系占全部根系的30.1%-50.0%,植株明显萎蔫;7级,变色根系占全部根系的50.1%-80.0%,植株萎蔫;9级,全株枯死。
计算方法:
病害防治效果(%)=(空白病情指数-药剂处理区病情指数)/空白对照区病情指数×100;
害虫防效(%)=(对照区活虫数-药剂处理区活虫数)/对照区活虫数×100。
结果与分析
由表2可知,本发明制备的30%氯虫苯甲酰胺·丙硫菌唑·精甲霜灵种子处理悬浮剂对花生病虫害具有优异的田间防效,对蛴螬和根腐病的防治效果均为90%左右,特别是FS-1对蛴螬的防效为100%,对根腐病的防效为99.1%。
