The key to answering this question is understanding the meaning of the word "beneficial".  When something is beneficial to something else, it has a positive effect in one way or another on it.  Fertilizers are necessary for the nourishment and continued growth of the grass on the greens of the golf course.  Fertilizers cause the grass to grow at a constant rate and promote a lush, green appearance to the grass in general.  Herbicides are plant medicines that prevent growths and disease that would otherwise degenerate the growth and appearance of the golf course green.  Some of these herbicides kill weeds, some prevent fungi and mold growth, while others eradicate pests in the insect and animal kingdoms.  Both fertilizer and herbicide play an important part in the development and maintenance of a healthy, active golf course.
