Parasitic weeds are severe constraint to agriculture and major crop production, and the efficacy of available means to control them is minimal. Control strategies have centred around agronomic practices, resistant varieties and the use of herbicides. Novel integrated control programmes should be sympathetic to agricultural extensification while exerting minimal harmful effects on the environment. This eBook covers recent advances in biology, physiology of parasitism, genetics, population dynamics, resistance, host-parasite relationships, regulation of seed germination, etc., in order to offer an outstanding windows to these enigmatic plants, and contribute to their practical management.

The parasitic lifestyle in plants has always been the subject of curiosity of scientists, but during the last decade, our understanding of parasitic plant–host interactions has greatly evolved due to rapid advances in molecular and genomic tools, especially high throughput DNA sequencing, transcriptomics, and metabolomics. Recent findings taken the science of parasitic plants to a higher level, opening up new horizons in parasitic weed management. The discovery of a novel family of phytohormones, the strigolactones, and their involvement in the host detection and evolution of parasitic plants, the detection of information exchange between host and parasite, and elucidation of the suppression of host defense mechanisms by parasites has led to a deeper understanding of physiological processes in host–parasite interactions. In the light of recent achievements, the re-evaluation of control management, including smart chemical control, crop breeding, and molecular genetics, are on the agenda.
