吡虫嗪是一种吡啶-甲亚胺类化合物，是一种选择性杀菌剂，具有较高的植物系统活性，可用于防治棉铃虫、粉虱和棉铃虫。通过生物测定和放射自显影技术，已经证明这种系统行为不仅起源于木质部，而且还起源于韧皮部的流动性。叶面施药后，植物生长点受到主要从叶片进口的吡虫啉的保护。这表明韧皮部的流动性对于吡咪去津对吸食植物的昆虫的系统活性具有高度的重要性。©1997年SCI。
Pymetrozine, a pyridine-azomethine, is a selective biocide against aphids, whiteflies and plant hoppers with a high plant systemic activity. By means of bioassays and autoradiographic techniques it has been shown that this systemic behaviour originates not only from xylem but also from phloem mobility. After foliar application the growing points of plants are protected by pymetrozine imports mainly from leaves. This indicates a high importance of phloem mobility for the systemic activity of pymetrozine against plant-sucking insects. © 1997 SCI.
