当将苯菌灵施用于开花天竺葵和一品红植物的根部时，在叶子中检测到杀菌活性，但在花瓣或苞片中未检测到杀菌活性。在结果的番茄植株中，苯菌灵主要被输送到叶子和浓处。果实中含量为叶中含量的0.03-2%。菜豆（Phaseolus vulgaris）中的浓缩物。果实中的含量为叶中的0.3-3%。那些未能积累杀菌剂的器官不存在气孔，因此得出结论，蒸腾作用控制了苯菌灵的全身积累。杀菌剂在叶缘和顶端的积累类似于染料在叶形滤纸片中的移动。显然，它在植物中的分布可以用物理基础来解释。
When benomyl was applied to the roots of flowering geranium and poinsettia plants fungicidal activity was detected in the leaves but not in the petals or bracts respectively. In fruiting tomato plants benomyl was transported mainly to the foliage and the conc. in fruit was 0.03-2% of that in the leaves. In bean (Phaseolus vulgaris) the conc. in fruit was 0.3-3% that in foliage. Stomata were absent from those organs which failed to accumulate the fungicide and it was concluded that transpiration governs the accumulation of benomyl systemically. The accumulation of fungicide at the leaf margins and apices resembled the movements of dye in leaf-shaped pieces of filter paper. Evidently its distribution in the plant may be explained on a physical basis.
