Abstract

Chemicals are widely recommended for the suppression of weed in crop land. This paper attempts to a greater integration of ideas into the development of herbicide resistance. This may lead researchers to focus less on simply defining herbicide resistance and more towards comprehensive investigations of the resistance development. Weed expert in collaboration with plant biologists can work in synergy to come up with better approach and innovation aimed to curtain herbicides resistance challenges. Chemical herbicides exert undue pressure on weed fitness and the diversity of weed community’s changes over time in response to both herbicides and other strategies imposed on them. Repeatedly and intensively, the regular application of herbicides with similar effect may swiftly result in population shifts to tolerant, difficult to suppress and ultimately result to weed community that is herbicide resistant, particularly in absence of using herbicides with different modes of action. Weed expert and evolutionary biologists have to work in synergy toward an improve and broader knowledge of plant resistant development. This collaboration is likely to proffer innovative solutions to the herbicide resistance challenges.

Summary

Introduction

Herbicides are applied widely as a weed control tool in cropping systems across the globe. Finnoff et al (2007) indicated how managers who are cautious risk averse are less likely to adopt preventive measures because prevention only reduces the risk, rather than eliminating it This perception is likely true for growers comparing the value of prevention control against the cost of herbicide resistance. In an illustration of more than 1000 corn, cotton and soybean growers in the United States, Frisvold et al (2009) determined that using multiple herbicides with different MOAs was one of the least-adopted methods for herbicide resistance management, despite this practice being frequently identified by scientists as an efficient ways to reduce the risk of resistance development. The most favorable practice is to proactively use annual herbicide rotations and sequential applications before resistance evolves, that requires growers using multiple herbicides with different MoAs (Fig. 2) even if weed densities are low (Powles et al, 1997). More research is required on the use of combined herbicide practices on already-resistant weed species, as well as on the potential for such methods to select for cross resistance (Preston, 2004)
