98% Pesticides Raw Materials Gibberellic Acid Powder For Plant Growth Regulation

In 1926, Eiichi Kurosawa discovered that when rice is infected with Gibberella, the plants will grow wildly. The diseased plants are often more than 50% higher than normal plants, and the seed setting rate is greatly reduced, so it is called "bakanae disease". . Scientists sprayed the filtrate of Gibberella culture medium on healthy rice seedlings and found that although these seedlings were not infected with Gibberella, they developed the same symptoms as "bakanae disease". In 1938, Sadajiro Yabuda and Yusuke Sumigi isolated this active substance from the filtrate of the gibberellum culture medium and identified its chemical structure. Named gibberellic acid.
