Abstract
本发明涉及一种用于防除有用植物中禾草和杂草的组合物,它包括:a)除草有效量的式I化合物,其中各取代基如权利要求1中定义;b)拮抗除草剂作用有效量的安全剂,所述安全剂选自喹氧乙酸,喹氧乙酸的碱金属、碱土金属、锍或铵阳离子盐,或喹氧乙酸异庚酯,吡咯二酸,吡咯二酸的碱金属、碱土金属、锍或铵阳离子盐,以及吡咯二酸二乙酯;和c)一种添加剂,包括植物或动物油、矿物油、它们的烷基酯或这些油和油衍生物的混合物。
Description
本发明涉及用于防治有用作物,尤其是玉米和谷类作物中的禾草与杂草的新型选择性除草组合物,该组合物包括3-羟基-4-(4-甲基苯基)-5-氧代-吡唑啉除草剂、安全剂(反作用剂,解毒剂)以及油添加剂,并且能保护有用植物免受除草剂的植物毒性作用,但不保护杂草。本发明还涉及此类组合物在防除有用作物中杂草方面的用途。
在施用除草剂时,由于受例如除草剂的使用量及其施用方式、栽培植物种类、土壤的性质以及气候条件(例如光照时间、温度和降雨量)等因素影响,栽培植物也可能会受到严重的损害。为了解决此类问题,已经有多种物质被建议用作安全剂,它们能拮抗除草剂对栽培植物的有害作用,也就是说它们能保护栽培植物,但不会明显减损除草剂对欲防治杂草的作用。
业已发现,这些所推荐的安全剂对栽培植物与杂草的作用通常非常专一,而且在某些情况下还与施用方法有关,也就是说,特定的安全剂通常只适用于特定的栽培植物和特殊种类除草物质或特定除草剂。例如,业已发现,虽然安全剂喹氧乙酸和喹氧乙酸异庚酯以及吡咯二酸和吡咯二酸二乙酯(见EP-A-0191736(化合物1.316)和WO91/07874(实施例3)及《杀虫剂手册》(The Pesticide Manual),第11版,BritishCrop Protection Council,Entry No.154和462)能够保护栽培植物免受特定的3-羟基-4-(4-甲基苯基)-5-氧代-吡唑啉衍生物的植物毒性作用,但它们却在某些情形下会降低对杂草的除草作用。
US-A-4834908中公开了某些油添加剂混剂可以增强环己烷二酮类化合物、苯并噻二嗪酮二氧化物类化合物、二苯醚除草剂以及芳氧基苯氧基除草剂类化合物的除草活性。
虽然3-羟基-4-(4-甲基苯基)-5-氧代-吡唑啉衍生物的结构完全不同于US-A-4834908中公开的化合物,但这种油添加剂与所述3-羟基-4-(4-甲基苯基)-5-氧代-吡唑啉衍生物混用同样能够增强除草活性,同时又会对栽培植物产生明显损害。因此这种除草剂/油添加剂混合物不适合于选择性防治有用作物中的杂草。
令人惊奇的是,现已发现通过将特定的3-羟基-4-(4-甲基苯基)-5-氧代-吡唑啉除草剂与包括植物或动物油或矿物油、它们的烷基酯、或这些油和油衍生物的混合物的添加剂,以及与安全剂喹氧乙酸或吡咯二酸混合施用,这类特定除草剂能够非常成功地选择性防除杂草,而且不会损伤栽培植物。

本发明还涉及一种选择性防除有用植物中杂草的方法,该方法包括用a)除草有效量的式I除草剂,b)拮抗除草剂作用有效量的选自喹氧乙酸,喹氧乙酸的碱金属、碱土金属、锍或铵阳离子盐,或喹氧乙酸异庚酯,吡咯二酸,吡咯二酸的碱金属、碱土金属、锍或铵阳离子盐,以及吡咯二酸二乙酯的安全剂,和c)一种包括植物或动物油或其烷基化衍生物,或矿物油或其混合物的添加剂来处理有用植物、其种子或秧苗或其种植区。
可以使用安全剂喹氧乙酸,喹氧乙酸的碱金属、碱土金属、锍或铵阳离子盐,或喹氧乙酸异庚酯,吡咯二酸,吡咯二酸的碱金属、碱土金属、锍或铵阳离子盐,或吡咯二酸二乙酯加以保护来抵御上述除草剂的有害作用的栽培植物特别是禾谷类作物、棉花、大豆、甜菜、甘蔗、栽培作物、油菜、玉米和稻,更优选玉米和禾谷类作物。作物应理解为还包括利用常规繁殖方法或基因工程方法产生的能耐受某种或多种除草剂的作物。这例如是IMI小麦,Poast Protected小麦(耐稀禾定),LibertyLink小麦B.t./Liberty Link小麦IMI/Liberty Link小麦,IMI/Liberty Link/B.t.小麦,Roundup Ready小麦以及RoundupReady/B.t.小麦。
要防除的杂草可以是双子叶或者优选单子叶杂草,例如单子叶杂草燕麦属、剪股颖属、虉草属、黑麦草属、雀麦属、看麦娘属、狗尾草属、马唐属、臂形草属、稗属、黍属、高粱属(Sorghum hal./bic.)、筒轴茅属、莎草属、臂形草属、稗属、莞草属、雨久花属和慈姑属,以及双子叶杂草如白芥属、藜属、繁缕属、猪殃殃属、堇菜属、婆婆纳属、母菊属、罂粟属、茄属、茼麻属、黄花稔属、苍耳属、苋属、番茄属和茼菊属。
种植区是指已经生长有栽培植物或者已经播种了这些栽培植物种子的区域,以及意欲种植这些栽培植物的区域。
依据预定用途,本发明的安全剂可以用于预处理栽培植物的种子(拌种或拌苗)或者可以在种子播种前后掺入土壤中。然而,也可以在植物出芽之后单独或与除草剂和油添加剂一起施用。因此,用安全剂处理植物或种子原则上讲可以与除草剂的施用时间无关。但也可以同时施用除草剂、油添加剂和安全剂(例如以桶混物形式)对植物进行处理。安全剂相对于除草剂的施用量在很大程度上取决于施用方法。在使用安全剂与除草剂混合的桶混物或单独使用安全剂与除草剂进行大田处理的情况下,除草剂与安全剂之比通常为100∶1-1∶10,优选20∶1-1∶1。在大田处理的情形下,通常每公顷施用0.001-1.0kg安全剂,优选0.001-0.25kg安全剂。
除草剂的施用量一般为0.001-2kg/ha,但优选0.005-1kg/ha。
在本发明的组合物中,所用的油添加剂的量通常为0.01-2%(以喷雾混合物为基准)。油添加剂例如可以在喷雾混合物制备之后以需要浓度加到喷雾器中。
优选的油添加剂包括矿物油或植物油例如菜子油、橄榄油或向日葵油,乳化的植物油,如由Rhne-Poulenc Canada Inc.得到的AMIGO,植物油的烷基酯例如甲基衍生物,或动物油如鱼油或牛油。特别优选“A型添加剂”,它包含基本上80重量%的鱼油烷基酯和15重量%甲基化菜子油作为活性组分,以及5重量%常规乳化剂和pH调节剂。
特别优选的油添加剂包括高级脂肪酸(C8-C22)的烷基酯,尤其是C12-C18脂肪酸的甲基衍生物,例如月桂酸、棕榈酸和油酸的甲基酯。这些酯称为月桂酸甲酯(CAS-111-82-0),棕榈酸甲酯(CAS-112-39-0)和油酸甲酯(CAS-112-62-9)。特别优选的脂肪酸甲酯衍生物是Emery2230和2231(Henkel Tochtergesellschaft CognisGMBH,DE)。
油添加剂的施用与作用可以通过将它们与表面活性物质如非离子型、阴离子型或阳离子型表面活性剂混合而得以改进。合适的阴离子型、非离子型和阳离子型表面活性剂的实例列于WO97/34485的第7与第8页中。
优选的表面活性物质为十二烷基苄基磺酸盐型阴离子型(尤其是其钙盐)表面活性剂,以及乙氧基化脂肪醇型非离子型表面活性剂。特别优选具有5-40乙氧基化度的乙氧基化C12-C22脂肪醇。优选的市售表面活性剂的实例为Genapol类型(Clariant AG,Muttenz,瑞士)。表面活性物质的浓度(以总添加剂为基准)通常为1-30%重量。
由油或矿物油或其衍生物与表面活性剂的混合物组成的油添加剂的实例为Edenor ME SU,Turbocharge(Zeneca Agro,StoneyCreek,Ontario,Canada)或者更优选为Actipron(BP Oil UKLimited,GB)。而且,向油添加剂/表面活性剂混合物中加入有机溶剂可以进一步提高效果。适宜的溶剂例如为Solvesso(ESSO)或Aromatic Solvent(Exxon Corporation)类型。这些溶剂的浓度可以为总重量的10-80%。
这类油添加剂还记载在例如US-A-4834908中,并且对于本发明组合物来讲是特别优选的。已知的特别优选的油添加剂的商品名为MERGE,它可以从BASF公司购得,并且主要记载在例如US-A-4834908的第5栏中(见实施例COC-1)。本发明优选的其它油添加剂为SCORE(Novartis Crop Protection Canada.)。
本发明的组合物适合农业上常用的任何施用方法,例如芽前施用、芽后施用和拌种。
就拌种而言,通常施用0.001-10g安全剂/kg种子,优选0.05-6g安全剂/kg种子。当安全剂以液体形式在临播种前通过浸种施用时,宜使用安全剂的溶液,其中包含有浓度为1-10000ppm,优选10-1000ppm的活性成分。
就施用而言,宜将本发明的安全剂或这些安全剂与式I除草剂以及油添加剂的混剂与加工配制领域惯常使用的助剂一起配制成各种制剂,例如乳油、可涂布糊剂、可直接喷雾或可稀释溶液、稀乳剂、可湿性粉剂、可溶性粉剂、粉剂、颗粒剂或微囊剂。
这些制剂记载于例如WO97/34485中的第9-13页。制剂用已知方法制备,例如通过将活性成分与液体或固体制剂用助剂(例如溶剂和固体载体)充分混合和/或研磨来制备。另外,在制备制剂时也可以使用表面活性化合物(表面活性剂)。例如在WO97/34485的第6页中给出了适于此目的的溶剂和固体载体。
根据所配制的式I活性成分的性质,合适的表面活性化合物是具有良好的乳化性、分散性和湿润性的非离子型、阳离子型和/或阴离子型表面活性剂以及表面活性剂的混合物。例如在WO97/34485的第7和8页中列出的合适的阴离子型、非离子型和阳离子型表面活性剂的实例。此外,特别是在“Mc Cutcheon’s Detergents and EmulsifiersAnnual”MC出版公司,Ridgewood New Jersey,1981,Stache,H.,“Tensid-Taschenbuch”,Carl Hanser Verlag,Muenhen/Wien,1981和M.和J.Ash,“表面活性剂大全”(Encyclopedia ofSurfactants),VolI-III,Chemical Publishing Co.,New York,1980-81中描述的制剂加工领域惯用的表面活性剂也适用于制备本发明的除草组合物。
除草组合物通常含有0.1-99%重量、尤其是0.1-95%重量的包括式I化合物与本发明安全剂的活性成分混合物,0.01-2%重量的本发明油添加剂,1-99.9%重量的固体或液体加工助剂以及0-25%重量、尤其是0.1-25%重量的表面活性剂。虽然市售产品优选配制成浓缩物形式,但最终用户往往要使用稀释制剂。
组合物中还可以包含其它添加剂,例如稳定剂如植物油或环氧化的植物油(环氧化的椰子油、菜籽油或大豆油)、消泡剂如硅油、防腐剂、粘度调节剂、粘结剂、粘附稠剂,以及肥料或其它活性成分。为了保护栽培植物免受式I除草剂的有害作用,有多种适宜的方法和技术来使用本发明的安全剂或包含它们的组合物;下述方法只是这些方法的举例。
i)拌种
a)通过在容器中振动,用本发明安全剂活性成分的可湿性粉剂包衣种子,直至制剂均匀分布于种子表面(干式拌种)。每100kg种子使用大约1-500g本发明安全剂活性成分(4g-2kg可湿性粉剂)。
b)按照方法a),用本发明安全剂的乳油包衣种子(湿式拌种)。
c)用包含100-1000ppm本发明安全剂的液体制剂浸泡种子1-72小时进行拌种,随后如果需要干燥种子(浸没式拌种)。
拌种或处理发芽籽苗自然是优选的施用方法,因为这样的活性成分的处理是直接完全作用于靶标作物。通常,每100kg种子使用1-1000g解毒剂、优选5-250g解毒剂,但依据使用方法也可以加入其它活性成分或微量营养元素,并且用量也可以高于或低于所示浓度范围(重复拌种)。
ii)桶混施用
使用解毒剂与除草剂的混合物的液体制剂(相互比率为20∶1-1∶100),除草剂的施用量为每公顷0.005-5.0kg。加入到桶混物中的油添加剂的量优选为0.01-2%重量。这种桶混物可以在播种之前或之后施用。
iii)种子犁沟施用
将配制成乳油、可湿性粉剂或颗粒剂形式的安全剂施于已播入种子的开挖犁沟内。在种子犁沟覆盖上土后,按照常规方式芽前施用除草剂(任选与油添加剂混用)。
iv)活性成分的控制释放
将安全剂溶液施加到颗粒化矿物载体或聚合物颗粒(脲-甲醛)上,然后干燥。如果需,进行包衣(包衣颗粒),从而使得活性成分能够在预定时期内计量释放。

本发明组合物的除草选择性作用用下列实施例加以说明。
生物实施例
实施例B1:芽后试验:
在温室条件下在盆中培育试验植物至芽后施药阶段。使用标准土壤作为生长介质。在芽后阶段,将除草剂单独和以与安全剂和/或油添加剂的混合物形式施于试验植物或者施于用安全剂拌种过的栽培植物。给药利用试验物质的乳液形式(由乳油(实施例F1,c)制备)进行。施用量取决于在大田条件或室温条件下确定的最佳剂量。2-4周后对试验进行评价(100%作用=完全杀灭,0%作用=无植物毒性作用)。
除草剂的施用量在每种情况下都为25g/ha;喹氧乙酸异庚酯的施用量为6.25g/ha。作为油添加剂,MERGE的使用浓度为喷雾混合物重量的1%。表B1.1:序号1.007化合物与序号1.008化合物的除草作用
试验植物 | 序号1.007化合物 | 序号1.008化合物 |
小麦 | 0 | 0 |
阿披拉草(Apera) | 60 | 25 |
看麦娘 | 10 | 20 |
燕麦 | 10 | 20 |
在本试验中,序号1.007的除草剂和序号1.008的除草剂在25g/ha的施用量下对杂草仅显示出轻微至中等程度的杀草作用。栽培植物(小麦)在此施用量下不受损害。表B1.2:序号1.007化合物与序号1.008化合物与安全剂喹氧乙酸异庚酯混用的除草作用
试验植物 | 序号1.007化合物 | 序号1.008化合物 |
小麦 | 0 | 0 |
阿披拉草 | 45 | 25 |
看麦娘 | 20 | 15 |
燕麦 | 20 | 15 |
在本试验中,加入6.25g/ha喹氧乙酸异庚酯导致序号1.008化合物对所有受试杂草的除草作用都发生降低,然而序号1.007化合物对阿披拉草的除草作用则从60%降低到只有45%,但对看麦娘和燕麦的除草作用却从10%增加到仍不能完全令人满意的20%。栽培植物(小麦)在此施用量下不受损害。表B1.3:序号1.007化合物与序号1.008化合物与MERGE混用的除草作用
试验植物 | 序号1.007化合物+MERGE | 序号1.008化合物+MERGE |
小麦 | 60 | 50 |
阿披拉草 | 85 | 90 |
看麦娘 | 90 | 85 |
燕麦 | 95 | 95 |
在本试验中,序号1.007化合物和序号1.008化合物与MERGE混用对所有受试杂草都显示出强大的除草作用。但同时却观测到对小麦也产生严重损害。表B1.4:序号1.007化合物与序号1.008化合物与安全剂喹氧乙酸异庚酯和MERGE混用的除草作用
试验植物 | 序号1.007化合物+喹氧乙酸异庚酯+MERGE | 序号1.008化合物+喹氧乙酸异庚酯+MERGE |
小麦 | 0 | 0 |
阿披拉草 | 85 | 90 |
看麦娘 | 90 | 90 |
燕麦 | 95 | 90 |
令人惊奇的是,每种除草剂与喹氧乙酸异庚酯和MERGE的混用都能导致混合物对栽培植物产生显著的选择性。而杂草几乎被完全杀灭,小麦则基本上受到保护,避免了除草剂的植物毒性作用。
实施例B2:芽后试验(试验说明如实施例B1):
在该试验中,比较了序号1.008化合物与喹氧乙酸异庚酯组合的除草作用与序号1.008化合物与喹氧乙酸异庚酯以及不同的根据本发明的油添加剂的组合的除草作用。每种情况下除草剂的施用量为8g/公顷,喹氧乙酸异庚酯的施用量为2g/公顷。油添加剂以喷雾液的0.7重量%的浓度使用。结果在下表中示出。
表B2.1序号1.008化合物与喹氧乙酸异庚酯组合物的除草作用及序号1.008化合物与喹氧乙酸异庚酯以及Emery2231的组合的除草作用:
试验植物 | 序号1.008化合物+喹氧乙酸异庚酯 | 序号1.008化合物+喹氧乙酸异庚酯+Emery2231 |
小麦 | 10 | 0 |
看麦娘 | 0 | 60 |
毒麦(Lolium) | 0 | 80 |
序号1.008化合物+喹氧乙酸异庚酯的组合在试验所用施用量下对杂草没有除草作用,但对小麦却有10%的植物毒性作用。然而当将该混合物与油添加剂Emery2231组合时,杂草被严重杀灭。令人惊奇的是对作物却没有任何植物毒性作用(0%损害)。在下列表B2.2及B2.3中给出了表明了根据本发明的组合物令人惊奇的选择性改善的其它实施例。
