实例A
发芽前试验
溶剂:5重量份丙酮
乳化剂:1重量份烷芳基聚二醇醚
为了制备适当的活性化合物制剂,可将1重量份的活性化合物与所述量的溶剂混合,加入所述量的乳化剂,然后用水将所得浓缩物稀释至所需浓度。
将试验植物的种子播种在一般土壤中,24小时后浇灌活性化合物制剂。有利的是使每单位面积的水量保持恒定。制剂中活性化合物的浓度并不重要,只有每单位面积所施用的活性化合物的量才是决定性因素。经过3周后,评定对植物的损害程度,用与未处理对照植物的发育比较的损害%表示。指数表示:
10%=没有作用(像未处理对照植物一样)
100%=全部毁灭
例如,在本试验中,按照制备实例3和5的化合物表现出,当施用量为125克/公顷时,对庄稼植物而言,其耐药力良好,例如大麦损害为(0%),而对杂草则具有很强的作用,例如

溶剂:5重量份丙酮
乳化剂:1重量份烷芳基聚二醇醚
为了制备适当的活性化合物制剂,可将1重量份活性化合物与所述量的溶剂混合,加入所述量的乳化剂,然后用水将所得浓缩物稀释至所需浓度。
用活性化合物制剂喷洒已长至5-15cm高的试验植物,以施加每单位面积所要求的活性化合物的特定量。经过3周后,评定对植物的损害程度,用与未处理对照植物的发育比较的损害%表示。指数表示:
0%=没有作用(像未处理对照植物一样)
100%=全部毁灭
