Induced Mutation: A New Paradigm in Pulse Weed Control Strategies

Abstract

Pulses hold a remarkable significance by providing affordable source of dietary protein and other vital nutrients. However, various biotic (weeds, pathogens, and insect infestation) and abiotic (temperature, nutrient stress, waterlogging, drought, salinity, and heavy metals) constraints induce substantial harm by decreasing its production. Weeds pose a significant global challenge as these not only compete with crop for vital resources such as sunlight, space, nutrients, and water but also attract other pests and pathogens that can harm the pulse crops. The weed–crop intervention varies significantly based on the crop type, topography, and soil characteristics. The implementation of chemical weed control strategies not only revolutionized the global agriculture but also widely acknowledged as an essential tool in accelerating crop productivity. Pre-emergent herbicides are easy to get in the market; however, the lack of post-emergence herbicides for certain pulses is of primary concern. The use of alternative weed control chemicals not just eradicates weeds but the risk of damaging the pulse crop may persist. The development of herbicide-resistant crop using modern techniques is the current objective of plant researchers. For this aim, induce mutation stands out the most cost-effective and reliable option, which can be accomplished using both physical and chemical mutagens.
