The manual entitled “Practical Manual on Weed Management” has been designed to fulfill the requirement of post graduate students of Agronomy offering the course “Principles and Practices of Weed Management”. The manual is prepared strictly following the syllabus of the course. The manual makes an attempt to present the available information on practicals in weed science in a very simple and lucid language. The manual contains practicals on identification of weeds in field along with photographs, weed survey in cropped and non-cropped areas, preparation of weed herbarium, weed crop competition studies, an introduction to herbicides, herbicide application equipments, and their maintenance calibration of spray equipments. This manual also included solved and unsolved numerical problems pertaining to computation of herbicide doses and important weed indices, economic evaluation of weed control options, etc. The students community may harness benefit from this manual not only in learning the course but also very useful in research. I hope this manual will be very useful for the students, teachers, researchers and extension specialists and other interested in weed management.
