试验实施例1
对已耕地杂草的出苗前土壤处理试验
制备方法载体:丙酮,5重量份乳化剂:苄氧基聚乙二醇醚,1重量份
将1重量份活性化合物与上述量的载体和乳化剂混合,得到乳剂。将规定量的该乳剂用水稀释,制得试验药品。
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。
制剂实施例1(颗粒剂)
将25份水加至10份化合物65、30份膨润土(蒙脱石)、58份滑石粉和2份木素磺酸盐的混合物中,充分捏合,接着用挤出式制粒机在10-40筛中制粒,并于40-50℃干燥,获得颗粒剂。
制剂实施例2(颗粒剂)
将95份粒度分布为0.2-2mm的粘土矿物颗粒和5份化合物68投入旋转式混合器中,在旋转下喷入液体稀释剂以进行均匀润湿,接着于40-50℃干燥,得到颗粒剂。制剂实施例3(乳剂)
将30份化合物71、55份二甲苯、8份聚氧乙烯烷基苯基醚和7份烷基苯磺酸钙搅拌混合获得乳剂。制剂实施例4(可湿性粉剂)
将1 5份化合物245、80份White Carbon(水合无定形氧化硅的细粉)和粘土粉末(1∶5)的混合物、2份烷基苯磺酸钠和3份烷基萘磺酸钠和甲醛的缩合物粉碎并混合,制得可湿性粉末。制剂实施例5(可湿性颗粒剂)
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。
