ABSTRACT Herbicides are most popular and effective for weed management due to their higher efficacy and time saving nature. But the continued use of herbicides created many problems like weed resistance, shift weed in shift flora, and environment hazards. From these all problems herbicide resistance is very serious problem in present time all over the world. The main reasons of resistantce are lack of rotation of the herbicide and use of herbicides with long residue period. Herbicide resistance is a worldwide phenomenon and number of resistant biotypes of weeds is increasing at an alarming rate. Currently there are 480 cases of herbicide resistance in 252 plant species. Herbicide resistance in weeds should be minimised because it is major limiting factor of food security. A proper knowledge of development and mechanism of resistance would help us for its management. Herbicide resistance problem controlled with integrated weed management practices, including crop and herbicide rotations, herbicide combinations, and cultural, mechanical and biological methods of weed control.
