适宜的分散剂有例如木素亚硫酸盐废液和甲基纤维素。
粘合剂亦可以任选地用在制剂例如粉剂、颗粒剂、浸有活性化合物的天然的和人造的材料或乳剂中,这样的粘合剂可举出以下实例:羧甲基纤维素,天然的和合成的聚合物例如阿拉伯胶,聚乙烯醇和聚乙酸乙烯酯以及天然的磷脂例如脑磷脂和卵磷脂,和合成的磷脂。矿物油和植物油亦可被用作另外的添加剂。
还可以使用着色剂例如无机颜料,如氧化铁、二氧化钛和普鲁士蓝,和有机染料,如茜素染料、偶氮染料和金属酞菁染料,以及微量营养物如金属盐,例如铁、镁、硼、铜、钴、钼和锌的盐。
在所述制剂中活性化合物的含量一般在0.1-95%(重量)之间,0.5-90%(重量)为佳。
本发明的活性化合物可直接或以所述制剂的形式用于防治杂草并可与任何已知的除莠剂混合。这些混合物可以事先以最终制剂的形式制得,或者通过使用前进行桶混合来制备。
可将按照本发明的式(I)活性化合物与化学损伤减缓剂混合。通过此种混合,可大大扩展选择性除莠剂的可施用性。
化学损伤减缓剂可举1-(α,α-二甲基苄基)-3-对甲苯基脲为例。
按照本发明的式(I)活性化合物可被直接施用,或者以上述的制剂形式施用,施用方法为常规方法,例如液体散布、喷雾、雾化、撒粉或散播颗粒。
按照本发明的式(I)活性化合物可在出苗前或出苗后的任何阶段施用,亦可在播种前将其掺至土壤中。
对活性化合物的施用量无严格限制,可根据所需效果、目标植物(一种或多种)的种类、施用地点、施用时间等在宽范围内变动。但作为试验性估量,例如施用量可例如为每公顷大约0.001-10kg活性化合物,最好为每公顷大约0.01-5kg活性化合物。
下面的实施例将对本发明化合物的制备方法和用途进行举例说明,但决不应认为是对本发明的限制。其中的术语“份”,除另作说明外,均指“重量份”。合成实施例1

在温室中,将稗属和苋属的种子各播种在装有已耕地土壤的120cm2的花盆中的表层,用土覆盖,并将规定量的上述试验药品各均匀地撒布在试验花盆中的土壤的表层。施用4周后检查除莠效果。在全部死亡的情况下,将除莠效果评定为100%,而将未处理过的区域观察到同等生长的情况的除莠效果评定为0%。
结果
通过施用1kg/公顷作为有效成分的第65、68、71、81、96、211、245、248、250、258、263、310和319号化合物100%地消灭掉目标杂草。
试验实施例2
对已耕地杂草出苗后叶面处理的试验试验方法
在温室中,将稗属和苋属的种子各播种在装有已耕地土壤的120cm2花盆中并用土壤覆盖。播种并覆盖土壤10天后(这时杂草平均来看是处于2叶阶段),将按类似于上述试验实施例1的方法制得的各规定量的药品均匀地撒布在试验花盆中的受试植物的叶片部分上,撒布3周后,检查除莠效果的程度。
结果
通过施用1kg/公顷作为有效成分的第68、96、250、310和319号化合物,不低于90%的目标杂草被消灭掉。

可湿性颗粒剂如下制备:将20份化合物310、30份木素磺酸钠、15份膨润土和35份煅烧过的硅藻土粉末充分混合,然后加水并将所得到的混合物挤压通过0.3mm筛,随后干燥。
本发明的效果
按照本发明的新除莠四唑啉酮衍生物可用如实施例中所示的常规制备方法容易地合成,并能显示出作为除莠剂的有效作用。
