Qingyuan Agricultural Crown, headquartered in Qingdao, China, was established in 2009. It is a leading agricultural biotechnology enterprise in the world, committed to improving the efficiency and quality of world agricultural production from two dimensions of new pesticide creation and biotechnology breeding, and making contributions to world food security. Since this enterprise is not a state-owned enterprise, it is a private enterprise, not a state-owned enterprise.
Qingyuan Agricultural Crown successfully listed four landmark patented compound herbicides, namely cyhalofop-butyl, oxadiazon, triazole-mesotrione and oxadiazon, which had a far-reaching impact on rice, wheat and corn planting in China and even the world.
