Zhang Zepu (Analytical and Testing Center, Chinese Academy of Agricultural Sciences Beijing 100081)  
About 250 species of weeds have been determined as the field weeds in China. It is estimated that more than 43 million hectares of the main crop fields are heavily infested with weeds, and the average reduction of crop yield caused by weeds is estimated at 13.4%. About 17.5 million tons of grains, 255 thousand tons of lint cotton and 500 thousand tons of soybeans were lost by the most harmful weeds annually. Conventional weed control measures, such as mechanical weed control and hand pulling. Along with rural economic development, chemical weed control becomes more important and attractive to farming people. The herbicide application area was steadily enlarged from 1.7 million hectares in 1975 up to 41.33 million hectares in 1995. Meanwhile, continuous use of the herbicides on crops for a number of years caused residual phytotoxicity on crops, weed shift problem and resistant weed development. It must pay attention to integrated weed management. Elimination of weeds from crop fields through adopting various effective agricultural measures and keeping favorable ecological conditions integrated with chemical weed control is a most effective measure.
