With the development of new products to increase investment, in 25 years from 1990 to 2014, the new effective components of different categories of pesticides listed quantity decreased (Figure 4). Among them, in 1990 to 1999 10 years, about 130 new active ingredients listed, i.e., there are about 13 new active ingredients listed every year; in 2000 – 2009 years, about 100 new active ingredients listed, i.e., there are about 10 new active ingredients listed in the 2010 – year; in 2014 5, about 30 new active ingredients listed, i.e., there are about 6 new active ingredients listed every year. Thus, the development of a new effective component is more and more difficult.
Wang summed up the 6 factors of pesticide research and development costs:
The further integration of industry, investment companies to reduce new product creation. Because of regulatory requirements more stringent, into new products listed before the higher costs, many of the original can be listed varieties are not listed, which also contributed to the merger and reorganization of enterprises, to increase investment; at the same time, the company’s investment in R & D created more cautious.
The R & D investment more seeds and transgenic technology. Relatively easy to obtain transgenic technology achievements, and some test cost is also very low pesticide.

The effective components of development costs increased significantly.
The registration of the regulatory environment is more and more strict.
The attention of biological solutions. In recent years, such as Bayer spent great effort to the development of biological pesticide.
