ials and Methods We made several field surveys to different states of our country such as Tamilnadu, Andhrapradesh, Karnataka, Madhya Pradesh, Rajasthan, Uthrakand, Sathishgadh, Jharkand, Odyssa and West Bengal. We carried out contract cultivation and arranged for collection of weeds by providing training to the collectors. Based on our observation we compiled list of weeds, their abundance and distribution pattern, etc. Herbarium specimens of the weeds are collected and deposited in the R&D Centre, Natural Remedies Private Limited, Bangalore 560100. The identity of the specimens confirmed using regional floras. Results and discussion It is to be noted that weeds cause more damage to agriculture crops than pathogens or insect pests. In agriculture weeds compete against regular cash crops. Some of the acknowledged issues with weeds are tabulated below4-5. i) block major resources, compete for space, water, fertilizer, and land ii) overgrow than regular crops and block sunlight iii) lower quality of agricultural produce iv) lower quality of pasture v) increase in cost of production vi) block irrigation vii) harbor pests and serve as hosts for crop diseases viii) reducing crop quality by contaminating the commodity ix) interfering with harvest x) limiting the choice of crop rotation xi) producing chemical substances that can be allergens or toxins to humans, animals, or crop plants (allelopathy) xii) producing thorns and woody stems that cause irritations and abrasions to skin, mouths, or hooves of livestock xiii) being unsightly, dominant, aggressive, or unattractive although some weeds are used as ornamentals in gardens xiv) obstructing visibility along roadways, xv) interfering with delivery of public utilities (power lines, telephone wires), xvi) obstructing the flow of water in water ways, and creating fire hazards xvii) accelerating deterioration of recreational areas, parking lots, buildings, and equipment xviii) invading exotic weed species that can displace native species in stabilized natural areas Weeds deplete large quantities of mineral nutrients and other resources more efficiently than crop plants and thrive better during unfavorable conditions compared to crops. Sometimes they absorb more nutrients t
