Herbicide Resistance and Its Management Strategies - A Review

Abstract

Due to their improved effectiveness and ability to save time, herbicides are the most widely used and effective weed control methods. However, prolonged use of herbicides brought about several issues, including environmental risks, shift weed in shift flora, and weed resistance. Herbicide resistance is one of the most significant issues worldwide today, out of all of these issues. The use of herbicides with extensive residual periods and a lack of rotation of the herbicide are the primary causes of herbicide resistance. Herbicide resistance is a global occurrence, and the number of resistant weed biotypes is alarmingly growing. In 252 plant species, there are already 480 occurrences of herbicide resistance. Weed herbicide resistance should be reduced since it is a significant barrier to food security. We could more effectively handle it if we thoroughly understood resistance development. Integrated weed management techniques, such as crop and herbicide rotations, herbicide combinations, and cultural, mechanical, and biological methods of weed control, can control the herbicide resistance problem.
