The Biology and Control of Weeds in Sugarcane provides a comprehensive discussion of the problems of weed control in sugarcane against the background of world-wide cultivation, with emphasis on Taiwan's intensive pattern of crop farming.

The book is divided into 12 chapters which present the following concepts of weed control in sugarcane: botanical description of sugarcane; the cultivation of sugarcane in relation to weed control; weeds associated with sugarcane and their biological characteristics; losses in crop production caused by weeds; chemical control of weeds; crop tolerance and weed responses to chemicals; evaluation of new herbicides; research and practices of chemical weed control; and application techniques and equipment utilized in weed control.

The book is an authoritative reference for agriculture students, lecturers, and scientists. The advances presented in the book are also an invaluable contribution to the expanding ""Weed Science"" and will serve as an excellent background and perspective for further weed studies.
