Wang analyzed the current situation of global development of new herbicides, he divided into 4 aspects.

The development of transgenic herbicide tolerant crops is a major factor affecting the herbicide market. In glyphosate resistant crops listed at the beginning, people have pessimistic that the herbicide market has come to an end, even in 2000, the company reduced herbicide discovery personnel. However, from the beginning of 2004, the market found glyphosate resistant weeds, when the company began to herbicide discovery work, so the relationship between the herbicide market and herbicide resistant transgenic crops is very close.

The resistant weeds. Resistance is an important factor in the development of herbicides, in fact is not only herbicides, insecticides, fungicides and so that their relationship with the resistance development closely.

The economic development, rising labor costs, also contributed to the development of herbicide market.
