New Plant Growth Regulator “784 ~ 1” also known as “PGRl” [3 ~ (2 ~ pyridyl) propanol], Tianjin Nankai University Institute of Elemental Organic Chemistry in 1978 synthesized. Over the past few years through the trials in Tianjin, Shandong and other peanuts have obvious yield-increase effect, and has the advantages of easy use, low cost, drug sources and so on.
