对于许多经济上重要的单子叶和双子叶有害植物,本发明的式I化合物具有突出的除莠活性。本发明的活性物质也对于多年生杂草有效,这些杂草从根茎、根状茎、或其它的多年生的器官上生长出来,很难控制。关于这点,是否在播种前、萌发前或萌发后使用该物质一般不重要。特别提及本发明化合物可以控制的单子叶和双子叶杂草群的代表例子,没有限制到的确定的物种。活性物质有效作用的杂草物种的例子包括单子叶植物:一年生燕麦属、黑麦、草属、看麦娘属、法拉里斯、稗、马唐属、狗尾草属和莎草属,和多年生的冰草属、狗牙根属、白茅属和高粱属、以及多年生的莎草属。
关于双子叶杂草物种,其作用可以扩展到的物种例如一年生的猪殃殃属、堇菜属、婆婆纳属、野芝麻属、繁缕属、苋属、白芥属、番薯属、黄花稔属、母菊属和苘麻属,和多年生杂草旋花属、蓟属、酸模属和艾属。本发明活性物质在水稻播种这种待定条件下有效控制有害植物,例如稗、慈姑属、泽泻属、荸荠属、蔗草和莎草属。如果将本发明化合物在萌芽前施用于土壤表面,可以在杂草长出前完全预防杂草的秧苗,或在杂草长出子叶时就停止生长,最后在三到四星期之后完全死亡。本发明化合物特别抗下述植物的活性优良,阿皮拉草、小野芝麻、卷茎蓼、繁缕、长春藤叶婆婆纳、阿拉伯婆婆纳、三色堇和苋、猪殃殃属和地肤。
虽然本发明化合物对于单子叶和双子叶的杂草具有优良的除莠活性,但对于重要的经济类作物植物,例如小麦、大麦、黑麦、稻子、玉米、甜菜、棉花和大豆却根本没有损害,或者是损害是微不足道的。特别是和谷类作物相容得很好,例如小麦、大麦和玉米,特别是小麦。因此,本发明化合物非常适于有选择地控制在农用作物或观赏植物中的无用植物。
由于它们的除莠性质,在已知或将要出现的遗传工程的植物耕种中,这些活性物质可以用于控制有害植物。转基因植物通常具有优越的性状,例如对特定杀虫剂特别是特定除草剂的抵抗力,对植物病害或植物病害的致病微生物的抵抗力,例如特定的昆虫或真菌、细菌或病毒的微生物。其它的特别性状与产品的下述条件有关,例如,数量、质量、贮存稳定性、组分和特殊的成分。如此,已经知道获得的转基因植物产品具有增加的淀粉含量或改进的淀粉质量或不同的脂肪酸成份。
本发明的式I化合物或其盐优选用于,经济上重要的转基因的作物和观赏植物,例如谷类,例如小麦、大麦、黑麦、燕麦、粟、稻子、木薯和玉米、或用于甜菜、棉花、大豆、油菜籽、马铃薯、番茄、豌豆及其他蔬菜类植物的耕种。式I化合物优选用于有用植物耕种的除草剂,这些植物具有抗药性或通过遗传工程对除草剂的毒害作用具有抗药性。
传统的繁育具有比已知植物具有改进形状植物的方法包括,例如传统的交配方法和突变株繁育。换句话说,可以借助于遗传工程的方法(参见,例如EP-0221044A,EP-0131624A)来得到具有改进性状的新植物。例如,已经描述了几个方法:
-为了改进植物中的淀粉合成,利用遗传工程改变作物植物(例如WO 92/11376,WO 92/14827,WO 91/19806);
-对特定的除草剂具有抗性的转基因作物植物,对草丁膦除草剂(例如EP-0242236 A,EP-0242246 A)或对草甘膦类除草剂(WO 92/00377),或对磺酰脲类除草剂(EP-0257993 A,US-5013659 A);
-例如棉花的转基因作物植物,它能够产生苏芸金杆菌毒素(Bt毒素),这种毒素可以防御特定害虫对植物的侵害(EP-0142924 A,EP-0193259 A);
-具有改进的脂肪酸成份的转基因作物植物(WO91/13972)。
已经知道许多能够制备具有改进性状转基因植物分子生物技术(参见,例如Sambrook等,1989,分子扩增,实验手册第二版,美国冷泉港实验室出版,冷泉港,纽约;或Winnacker“Gene und Klone”[基因和克隆],VCH Weinheim,第二版1996或Christou,“植物科学的趋势”1(1996)423-431))。为了实现遗传工程的操作,可能将核酸分子引入质粒,通过DNA序列的重组,发生突变或序列改变。利用上述的标准方法,例如可以交换底物、除去部分序列或增加自然的或合成的序列。为了将DNA片段互相连接,有可能在片段上附带有结合体或连接体。
可以用下述方法制备降低活性的基因产品的植物细胞,例如通过表达至少一种适当的反义-RNA、正义-RNA来达到共抑制的效果,或通过表达至少一种适当构造的核糖酶,它特定裂解上述基因产品的转录产物。
为此目的,有可能使用包含基因产物全部编码序列的DNA分子,包括有可能存在的任何旁侧序列,和使用包含仅仅一部分编码序列的DNA分子,这些部分必须足够长以达到在细胞中反义的效果。也可以使用与基因产物编码序列具有高度同源性但不完全相同的序列。
当在植物中表达核酸分子时,合成的蛋白质可以在任何期望的植物细胞室中定位。然而为了在特定的室定位,有可能例如将编码区和DNA序列连接,以确保在特定位置定位。这些序列为本领域所属技术人员已知的(参见,例如Braun等,EMBO J.11(1992)3219-3227;Wolter等,Proc.Natl.Acad.Sci.USA 85(1988),846-850;Sonnewald等Plant J.1(1991),95-106)。
利用已知的技术可以将转基因植物细胞重组到整个植物上。转基因植物可以为任何期望的植物品种,即单子叶和双子叶植物。用这样的方式,通过超表达、禁止或抑制同源(=自然的)基因或基因序列,或通过异种的(=外部的)基因或者基因序列的表达,有可能获得改进性状的转基因植物。
当在转基因的作物上使用本发明的活性物质时,除了具有在其它作物上可观察到的抑制有害植物的效果外,经常在相应的转基因作物上会有特殊的效果,例如可以改进或扩大控制杂草的范围,改进应用时的施用量,优选转基因作物的抗药性和除草剂的性能很好的结合,并且转基因的作物植物的生长和产率的影响。因此本发明也提供了所述化合物的用途,作为除草剂控制转基因作物植物中的有害植物。
另外本发明化合物可以明显调节作物植物的生长。通过调节参与植物代谢,使用这些化合物定向控制植物的组分和促进收获,例如使植物干化和矮化生长。而且它们也适于调节和抑制不希望的植物生长,而不破坏作物的生长。抑制植物的生长在许多单子叶植物和双子叶植物作物中起着非常重要的作用,因为这样可以减少或完全预防倒伏。
可以使用一般的制剂来应用本发明的化合物,可使用可湿性粉剂、浓缩乳剂、可喷洒的溶液、粉末或颗粒。这样本发明也提供了包括式I化合物的除草剂组合物。根据通常的生物学和/或化学的物理参数,可以用多种方式配制式I化合物。适合的制剂选择实例为:可湿性粉剂(WP)、水溶性的粉末(SP)、水溶性的浓缩物、浓缩乳剂(EC)、例如油在水中分散和水在油中分散的乳剂(EW)、可喷洒溶液、悬浮剂浓缩物(SC)、可分散油悬浮剂(OD)、以油或水为稀释剂的悬浮液、可混溶油的溶液、粉末(DP)、胶囊悬浮液(CS)、包核

以上各表可知,与对照化合物相比,本发明的化合物通过改变母环结构、取代基以及羧基衍生物类型等,明显提高了作物安全性和除草活性,尤其是对于玉米、水稻、小麦等关键农作物建立了良好的选择性,而对照化合物对主要作物选择性差,可见本发明取得了优异的意料之外的技术效果。
(5)苗前测试实验:
将单子叶和双子叶杂草种子以及主要作物种子(小麦、玉米、水稻、大豆、棉花、油菜、谷子、高粱)放置在装有土壤的塑料盆中,然后覆盖0.5-2厘米土壤,分别将供试的本发明化合物用丙酮溶解,然后加入吐温80,用一定的水稀释成一定浓度的溶液,播种后立即喷施。施药后在温室中培养4周,3周后观察实验结果,发现本发明的药剂多数在250克/公顷计量下效果出众,尤其对稗草、马塘、苘麻等杂草,且很多化合物对玉米、小麦、水稻、大豆、油菜有良好的选择性。
通过实验我们发现本发明所述化合物普遍具有较好的杂草防效,尤其对于玉米田、水稻田、小麦田广泛发生的杂草稗草、马唐、狗尾草等主要禾本科杂草以及苘麻、蔊菜、鬼针草等主要的阔叶杂草有良好的效果,具备良好的商业价值。尤其是我们注意到对于ALS抑制剂有抗性的蔊菜、播娘蒿、荠菜、麦家公、猪殃殃、繁缕等阔叶杂草有极高的活性。
(6)移栽水稻安全性评价与水田杂草防效评价:
在1/1,000,000公顷罐中装入水田土壤后,播种稗草、萤蔺、狼把草、野慈姑的种子,在 其上轻轻地覆盖土。其后以蓄水深0.5-1厘米的状态静置于温室内,第二天或者2天后植入野慈姑的块茎。其后保持蓄水深3-4厘米,在稗草、萤蔺、狼把草达到0.5叶,野慈姑达到初生叶期的时间点,将按照通常的制剂方法调制本发明化合物而成的可湿性粉剂或者悬浮剂的水稀释液,用吸液管进行均匀的滴下处理以达到规定的有效成分量。
另外,在1/1,000,000公顷罐中装入水田土壤后,进行平整,使蓄水深3-4厘米,第二天以移栽深度3厘米来移植3叶期的水稻(粳稻)。移植后第5天与上述同样地处理本发明化合物。
分别用肉眼观察药剂处理后第14天稗草、萤蔺、狼把草及野慈姑的生育状态,药剂处理后第21天水稻的生育状态,以上述1-5级的活性标准级别评价除草效果,很多化合物表现出了优异的活性和选择性。
注:稗草、萤蔺、野慈姑、狼把草种子均采集自中国黑龙江,经过检测对常规剂量的吡嘧磺隆有抗药性。
同时经过很多测试发现,本发明所述化合物很多对结缕草、狗牙根、高羊茅、早熟禾、黑麦草、海滨雀稗等禾本科草坪有很好的选择性,能防除很多关键禾本科杂草以及阔叶杂草。对不同施药方式下的甘蔗、大豆、棉花、油葵、马铃薯、果树、蔬菜等测试也显示出极好的选择性和商业价值。
