Description
技术领域
本发明属于农药技术领域，涉及一种含咪鲜胺的农药组合物。
背景技术
咪鲜胺(prochloraz)化学名称：N-丙基-N-[α-(2,4,6-三氯苯氧基)-1H-咪唑-1-甲酰胺，分子式：C15H16Cl3N3O2，本品为高效、广谱、低毒型杀菌剂，具有预防保护治疗等多重作用，内含咪鲜胺为咪唑类。常规使用防治瓜果蔬菜炭疽病、叶斑病，还可防治、水稻稻瘟病、水稻恶苗病、油菜炭疽病和菌核病。
噻虫嗪(thiamethoxam)，化学名称：3-(2-氯-1,3-噻唑-5-基甲基)-5-甲基-1,3,5-恶二嗪-4-基叉(硝基)胺，噻虫嗪是一种全新结构的第二代碱类高效低毒杀虫剂，对害虫具有毒害、触杀及内吸活性，用于叶面喷雾及土壤灌根处理。其施药后迅速被内吸，并传导到植株各部位，对刺吸式害虫如蚜虫、飞虱、叶蝉、粉虱,有良好的防效。查阅相关文献，尚未见有该农药液相色谱法的报道。
噻虫胺(clothianidin)，分子式：C6H8ClN5O2S,化学名称：(E)-1-(2-氯-1,3-噻唑-5-基甲基)-3-甲基-2-2-硝基胍，噻虫胺是新烟碱类中的一种杀虫剂，是一类高效安全、高选择性的新型杀虫剂，其作用与烟碱乙酰胆碱受体类似，具有触杀、胃毒和内吸活性。主要用于水稻、蔬菜、果树及其他作物上防治蚜虫、叶蝉、蓟马、飞虱等半翅目、鞘翅目、双翅目和某些鳞翅目类害虫的杀虫剂，具有高效、广谱、用量少、毒性低、药效持效期长、对作物无药害、使用安全、与常规农药无交互抗性等优点，有卓越的内吸和渗透作用，是替代高毒有机磷农药的又一品种。
噻虫啉(Thiacloprid)分子式：C13H5N4SCl化学名称：(3-((6-氯-3-吡啶基)甲基)-1,3-噻唑啉-2-亚基)氰胺，噻虫啉是新型氯代烟碱类杀虫剂。是防治刺吸式和咀嚼式口器害虫的高效药剂蚜虫4000——8000倍喷雾。
种子包衣技术是在传统的浸种或拌种技术基础上发展起来的一种应用很普遍的种子处理新技术。将干燥或湿润状态的种子，用含有粘结剂的农药或肥料等组合物所包，使在种子外形成具有一定功能和包覆强度的保护层，这一过程称为种子包衣，包在种子外面的组合物称之为种衣剂，是一种用于作物或其他植物种子处理的、具有成膜特性的农药制剂。种衣剂最大优点是能在种子外面形成一层比较牢固的薄膜。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。所以，种衣剂具有杀灭地下害虫、苗期害虫，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，较少种子用量等功效，最终达到防病治虫、保苗壮苗、提高产量的目的。
防治病虫害最容易产生的问题是抗药性的产生，其次为防治谱单一，农民使用时多次施药，造成环境污染严重，作物农药残留大，对人类健康不利。申请人将不同作用机理的杀菌剂与杀虫剂复配，达到一喷双防的目的，有效防治作物各种病害，扩大原单剂的防治谱，并不直接作用于作物，而在作物成长期间农药残留分解，对作物无残留或低残留，对食用者安全，并且增效作用显著，环境相容性极好，极大地减少了农药用药量，降低了农民的施药成本。

本发明实施例是采用室内毒力测定和田间试验相结合的方法。先通过室内毒力测定，明确两种药剂按一定比例复配后的共毒系数(CTC)，CTC＜80为拮抗作用，80≤CTC≤120为相加作用，CTC＞120为增效作用，在此基础上，再进行田间试验。
应用实施例二：
按配比组成的混合物，按霍恩氏法用健康大白鼠、加入进行毒性试验，试验结果如下：
1.本发明对大白鼠急性经口大于4240mg/kg
2.本发明对大白鼠急性经皮大于2150mg/kg
3.本发明对家兔眼、皮肤均呈无刺激性，根据毒性分级标准为低毒。
4.防治水稻恶苗病和苗期害虫的作用。
5.本发明在植物上有非常良好的持续性防病、杀虫作用，试验方法是：在室内条件下，采用PDA平板孢子萌发法，测定孢子萌发数、萌发率、抑制率，求出EC50值和共毒系数，即共毒系数大于100的为增效作用，小于100的为拮抗作用。
实验结果如下
表1咪鲜胺与噻虫嗪复配悬浮种衣剂药效试验
由表1可知，咪鲜胺与噻虫嗪复配悬浮种衣剂配比在50︰1至1：100时，共毒系数均大于120，说明两者在50：1至1︰100范围内混配均表现出增效作用，尤其是当咪鲜胺与噻虫嗪得配比在1：1至1：6时，增效作用更为明显突出，其中当咪鲜胺与噻虫嗪重量比为1︰6时共毒系数最大，增效作用最为明显。
表2咪鲜胺与噻虫胺复配悬浮种衣剂药效试验
由表2可知，咪鲜胺与噻虫胺复配悬浮种衣剂配比在50︰1至1：100时，共毒系数均大于120，说明两者在50：1至1︰100范围内混配均表现出增效作用，尤其是当咪鲜胺与噻虫胺得配比在1：1至1：6时，增效作用更为明显突出，其中当咪鲜胺与噻虫胺重量比为1︰5时共毒系数最大，增效作用最为明显。
表3咪鲜胺与噻虫啉复配悬浮种衣剂药效试验
由表3可知，咪鲜胺与噻虫啉复配悬浮种衣剂配比在50︰1至1：100时，共毒系数均大于120，说明两者在50：1至1︰100范围内混配均表现出增效作用，尤其是当咪鲜胺与噻虫啉得配比在1：1至1：6时，增效作用更为明显突出，其中当咪鲜胺与噻虫啉重量比为1︰4时共毒系数最大，增效作用最为明显。
