The highly diverse agriculture and\r\nfanning systems are beset with different types of weed problems. Weeds cause 10-80% crop yield losses\r\nbesides impairing product quality and causing health and environmental hazards. Invasive alien weeds\r\nare a major constraint to agriculture, forestry and aquatic environment. Crop-specific problematic weeds\r\n(weedy rice in rice) are emerging as a threat to cultivation, affecting crop production, quality of product\r\nand income of farmers. Traditionally, weed control in India has been . largely dependent on manual\r\nweeding. However, increased labour scarcity and costs are encouraging farmers to adopt labour and costsaving\r\noptions. These include herbicides whose market grew at an annual rate of 15%. Integrated weed\r\nmanagement (IWM) is being practiced by Indian farmers, with the level of adoption varying from one\r\nfarm to the other. The continuous application of isoproturon coupled with mono-cropping rotation of ricewheat\r\nhas led to the evolution of resistance in Phalaris minor Retz. In the northern part of India. Efforts\r\nto manage herbicide resistance have led to the adoption of conservation agriculture in the rice-wheat\r\ncropping system, as a component of IWM.\r\nResearch on weed management in India is mostly centred on herbicide efficacy. Herbicides, applied\r\nalone or in combinations, have been regarded as essential tools in the effective management of weeds in\r\ndifferent-ecosystems. IWM, which includes preventative, mechanical, cultural, chemical and biological\r\nmethods, is advocated in crop production systems as well as aquatic and forest ecosystems. Herbicideresistant\r\n(HR) transgenic crops have the potential to improve the weed management efficiency and\r\nfacilitate adoption of CA in India, provided the risks associated with such crops are examined in detail,\r\nprior to their adoption and commercialization. Newer weed management approaches must be developed\r\nconsidering the threat of HR weeds appearance in addition to the recurrence and persistence of weeds\r\nand the need to bring down weed management costs to enhance profit for farmers while protecting the\r\nenvironment. Understanding weed-ecology and-biology_and.using_infoimatioxLtechnoiogy, should be part\r\nof developing and disseminating effective, economical and ecologically advantageous IWM strategies in\r\nIndia. Detailed review of weeds and weed management' options of the past, present and future in India is\r\nmade in this chapter."^^ . "2015" . . . "Indian Society of Weed Science"^^ . .
