Herbicide resistance in plants: biology and biochemistry (original) (raw)

Herbicide resistance—what have we learned from other disciplines?

Journal of Chemical Biology, 2014

Herbicide resistance is a growing threat to agriculture and has parallels to resistances to fungicides and insecticides. However, there are many reasons to treat the resistance to herbicides differently. To highlight these similarities and differences, three pests, a weed, an insect, and a disease that have shown the ability to rapidly develop resistance to a variety of products and product classes were used as illustrations. The situation in herbicide resistance is approaching a point already experienced by the other pest control disciplines, and thus, it is worthwhile to revisit their experiences.

Herbicide resistance in weeds it’s Management

Journal of Pharmacognosy and Phytochemistry, 2018

Resistance of weeds to herbicides is not a unique phenomenon. The first report of insects resistant to insecticides was in 1908, plant pathogens resistant to fungicides in 1940, and of weeds resistant to herbicides (Triazines) in 1968. Herbicides are considered to be among the most widely used pesticides. However, over-reliance on them and absence of any preventive or other cultural practices resulted to the evolution and spread of herbicide-resistant weeds. Development of herbicide resistant biotypes may be threat to successful crop production. Resistance to herbicides is a serious problem worldwide. The cases of resistance are increasing at an alarming rate. Cross and multiple resistances have further complicated the situation. Though arrival of new molecules with different mechanisms of action can help overcome present cases of resistance, an overreliance on chemical weed control will continue to give rise to cases of resistance. Therefore, alternate management strategies must be...

Global Status of Herbicide Resistance Development: Challenges and Management Approaches

American Journal of Agricultural and Biological Sciences, 2017

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.

Current status of herbicide resistant weeds around the Globe

Journal of Crop and Weed, 2010

The incidence and wide spread of herbicide resistant weeds is a globalproblem. Over the past 65 years, repeated use of herbicides has resulted in the evolution of resistant weed species. The first resistant species to triazine was discovered in 1970 in the United States. Since then, a large number of weed species has evolved resistance to several classes of herbicide. Currently, there are 334 resistant biotypes, including 190 weed species (113 dicots and 77 monocots) in over 310, 000 fields around the world. Common resistant species are Chenopodium album and Amaranthus retrojlexus resistant to triazine, Phalaris minor resistant to isoproturon, P. minor and P. paradoxa resistant to diclofop, Echinochloa colona resistant to propanil, Echinochloa crusgalli resistant to butachlor, Eleusine indica resistant to trifluralin, lolium rigidum resistant to diclofop, Lactuca serriola resistant to metsulfaron, glyphosate resistance to Eleusine indica, Conyza canadensis, Lolium rigidum, and loliu...
