Abstract Warmest congratulations to the centennial birthday of Nankai Chemistry! During the founding of our new China, numerous serious pests such as locusts, rice planthopper, wheat rusts and epidemic diseases such as malaria, cholera, plague, parasites prevailing then were deadly fatal to our people. Regrettably we could not procure any effective chemicals then to combat with. To provide enough food to our people is always a paramount task. The president of Nankai University, the prestigious professor Yang Shi-Xian, selflessly rushed to organize a team of young teachers to develop an organo-phosphorus insecticide urgently then demanded on the market. Owing to the strong need of our nation along with professional Yang's personal expertise and charisma, and above all our beloved Chairman Mao Ze-Tong's historic visit to inspect a simple manufacturing device of organo-phosphrus insecticide in our Chemistry Department, thus Nankai's pesticide chemistry emerged as the times required. To meet the future demand of experts in China in this new area, Nankai Chemistry has since started a program to educate students in the science and technology in plant protection. With the firm support from organic chemistry discipline, Nankai pesticide chemistry has a distinctive characteristic of inter-disciplinary which feedbacks to organic chemistry to broaden its view and research area. Hereby we want to express our sincere thanks and cordial salutes to all the predecessors and pioneers. devoted to the establishment of this new discipline of pesticide chemistry on our campus.
