组合物
结构式(Ⅰ)的化合物以组合物的形式被应用,而该组合物是本发明的重要实施方案,它包括结构式(Ⅰ)的一种化合物和植物学上可接受的一种惰性载体。该组合物或者是分散在水中使用的浓缩配制剂,或者是不需进一步处理而使用的粉状或颗粒状配制剂。该组合物可根据农业化学技术中常用的方法和配方而制备,但它们是新颖的和重要的,因为其中本发明化合物的存在。然而,我们将给出该组合物的配方的一些描述,以确保农业化学家们能容易地制备出任何所需的组合物。
其中使用这些化合物的分散液通常是由这些化合物的浓缩配制剂而制成的含水悬浮液或乳液。这些水可溶的、水可悬浮的或可乳化的配制剂,或者是平常已知为可润湿粉末的固体,或者是平常已知为可乳化浓缩液或含水悬液液的液体。可以被压制形成水可分散颗粒的可润湿粉剂包括该活性化合物、一种惰性载体和表面活性剂的紧密混合物。活性化合物的浓度通常在约10%-约90%(重量计)。惰性载体通常可从硅镁土、蒙脱土、硅藻土或纯化硅酸盐中选择。包括约0.5%-约10%可润湿粉剂的有效表面活性剂是从磺化木素、缩合萘磺酸盐、萘磺酸盐、烷基苯磺酸盐、烷基硫酸盐和非离子表面活性如烷基酚类的环氧乙烯加成物中寻找。
该化合物的可乳化浓缩液包括适宜浓度的化合物,如每升液体
约50-约500克(相当于约10%-约50%),该化合物被溶于惰性载体中,该载体或者是水混溶性溶剂,或者是水不可混溶性有机溶剂和乳化剂的混合物。有用的有机溶剂包括芳香烃类(尤其是二甲苯类)和石油馏分(尤其是石油的高沸点萘属或烯属部分如重芳香石脑油)。还可使用其它有机溶剂,如萜烯类溶剂(包括松香衍生物),脂族酮类(如环己酮)和复杂醇类(如2-乙氧基乙醇)。可乳化浓缩液的合适乳化剂是选自普通的非离子表面活性剂,例如以上所讨论过的。
含水悬浮液包括本发明的水不溶化合物的悬浮液,该化合物的以在约5%-约50%(重量)范围的浓度分散在含水载体中。悬浮液是通过细磨该化合物并将它强烈地混合到包括水和选自上述同样类型的表面活性剂的载体中而制备的。为提高含水载体的密度和粘度,还可加入惰性成分如无机盐和合成的或天然的树胶。通过制备含水混合物并在一工具如混砂机、球磨机或活塞型均化器中使它均化,通常能够在同一时间最有效地磨细和混合该化合物。
该化合物还可以颗粒状组合物形式被施用,这种组合物特别有用于土壤施用。颗粒状组合物通常含约0.5%-约10%(重量)的该化合物,该化合物分散在全部或大部分由粘土或类似的廉价物质组成的惰性载体中。此类组合物通常是通过将该化合物溶于合适的溶剂中并将其施加于被预先制成合适颗粒尺寸(在约0.5-3mm的范围)的颗粒状载体而制得。此类组合物还可通过将载体和化合物制成
生面团或糊状,以及碾碎和干燥以获得所需颗粒尺寸而配制。
包含该化合物的粉剂是简单地通过将粉末形式的该化合物与适宜的粉末状农用载体如高岭土、磨细的火山石及类似物进行紧密混合而制成的。粉剂可较合适地含约1%-约10%的该化合物。
出于任何理由,以在合适的有机溶剂中的溶液形式使用该化合物同样是可行的,这种溶剂通常是无刺激性气味的石油如广泛用于农业化学的喷淋油。
杀虫剂和杀螨剂通常以活性成分在液体载体中的分散液的形式使用。根据活性成分在载体中的浓度来表示应用比率是普通的。最广泛使用的载体是水。
结构式(Ⅰ)的化合物还可以烟雾剂组合物的形式被施用。在这些组合物中,活性化合物溶解或分散在惰性载体中,这种载体是产生压力的推进剂混合物。该烟雾剂组合物包装在一个容器中,通过雾化阀将该混合物从容器中喷洒出来。推进剂混合物或者包括低沸点卤化碳类(可与有机溶剂混合),或者包括用惰性气体或气态烃类加压的含水悬浮液。
施加到昆虫和螨虫所在场所的化合物的实际用量并不是严格的,并且它可由本技术领域的熟练人员鉴于上述实施例来确定。一般来说,化合物从10ppm到5000ppm的浓度就可有希望获得好的控制效果。对于许多这些化合物,100-1500ppm的浓度就可满足需要。对于农作物如大豆和棉花,化合物合适的施用比率是约0.5-1.
5磅/亩(lb/A),典型地以50加仑/亩(gal/A)的、含1200-3600ppm化合物的喷雾配制剂来使用。对于柑橘作物,合适的使用比率是约100-1500gal/A的喷雾配方,它是100-1000ppm的比率。
施加化合物的场所可以是昆虫或蜘蛛栖居的任何场所,例如,蔬菜作物,水果和坚果树,葡萄藤和装饰植物。由于许多螨虫种类是相对于特殊宿主所特定的,前面所列螨虫种类提供了宽范围环境的例子,在这些环境中可使用本发明的化合物。
由于螨虫卵具有抵抗有毒物作用的独特本领,需要重复施用以控制新出现的幼虫,而这对于其它已知的杀螨剂也是一样的。
