PREFACE
Weeds pose serious problems in both crop and non-cropped areas and water-bodes. They infest lawn and gardens become troublesome along highways, railroads and industrial areas in irrigation and drainage systems and create health hazards to animal and human beings. Though a handbook of some South Indian weeds was published in 1932, the weed control as a Science was initiated since 1942. Since then the primitive methods of weed control are blended with the newest herbicide control techniques and 2,4-D was first used on a large scale in 1947. With the growing interest in weeds and weed control by the scientists of different disciplines, namely Ecologist, Plant Physiologist, Agronomist, Biochemist and others, the weed science has assumed great importance. It has made a considerable progress during last 40 years and progressively assuming an independent and significant branch of biological research. Workers in this field are now employed by educational institutions, government agencies, herbicide manufacturers and others. Chemical companies are spending millions of rupees in synthesizing, screening and developing new herbicides with trade names. With the availability of effective herbicides, there is an urgent need to bring together the present concept and modern techniques of weed control, along with complete enumeration of weed problems so as to cope with innumerable weed species, grown under various environments. However, since conditions vary as to methods of application and environmental conditions, the dose may be adjusted according to the need and
to be applied judiciously, based on the instructions printed on the label of the herbicides. The author has attempted to present the subject in an useful way and readable manner so as to understand easily. It will be helpful to research workers, college and University teachers, Vocational teachers, extension specialists, herbicide sale representatives and progressive farmers. Weed control practices suggested are based on research reports of several workers in this field and his own experience. However, farmers are not quite familiar to the use of herbicides as is the case of pesticides and fungicides only because they do not have adequate knowledge in the techniques of application, availability and also cost involvement. The book contains classification and description of monocot, dicot, aquatic and parasitic weeds reproduction and dissemination of weeds, allelopathy, weed control methods, classification of herbicides and mode of herbicidal action selective weed control in field crops plantations and Horticultural crops, grass lands and ornamentals residual effect of herbicides, along with useful illustrations.
