WEEDS IN GENERAL 



13 



few persons know weeds when they first come up. This bulletin 

 aims to acquaint persons with weeds in all of their different stages 

 of growth from the seed to the mature plant. Its purpose is to bring 

 to the farmers' attention only a few of the most common weeds of 

 the State.

It is hoped that the farmer will learn to know them whenever 

 he sees them and in whatever stage. It is planned to publish a series 

 of bulletins gradually extending the field to other weeds of the State. 

 The twenty-four weeds herein described are the weeds whose seeds 

 appear in weed seed case Series I, which has been prepared by the 

 Division of Plant Pathology and Botany. 



■This case is sold for a nominal sum. A second weed seed case 

 has been prepared containing twenty-four weed seeds, none of which 

 appear in Series I, and a bulletin will be issued describing the twenty- 

 four weeds whose seeds appear in this case. 



If the lessons of this bulletin were to be summed up in a few 

 words they are these: Know the weeds, not only in the seed form, but 

 in every other stage and condition. Start with a few of the worst 

 kind and gradually extend your acquaintance. When you know the 

 weeds learn the methods of eradication.
