This paper discusses bioherbicide development and the bioherbicides that have been commercialized forcontrol of special weed problems in field crops and woody plants.

The causes restricting bioherbicide development were discussed and some advice to solve it was put forward.

The bioherbicide is called to those living biological products which can be applied to prevent and control specific weeds effectively,can kill the natural enemy of the weeds,after carries on large dose biology preparation which the culture obtains under the artificial controlling conditions.

On Production Techniques for Commercialization of Colletotrium Gloeosporiodies Penz. as a Mycoherbicide for Veronica Persica Poir;

AHAS is the target for sulfonylurea, imidazolinone and other AHAS-inhibitor herbicides.

The Potential of Phytophthora.nicotianae as a Mycoherbicide Against Silene Conoidea;

This paper reviews the limiting factor on the exploitation of microbial herbicides .

In this paper,we summarized the categories of microbial herbicides,their formulations and characteristics and also introduced the potential superior.

This paper outlines the present situation, development, achievement andtendency of the studies on microbial pesticides at home and abroad, and principallycomments on the application and progress in the studies on bacterial insecticides,agricultural antibiotics and microbial herbicides.
