Recent approaches for herbicide resistance management in weeds: A review
International Journal of Chemical Studies, 2018
Herbicides are most effective and economic tool among the weed management practices. Use of herbicide is rapidly increasing in the world including India. Along with the advantages there are some disadvantages like herbicide resistance and environmental concern due to repeated use of herbicide. Development of resistance against the herbicides in targeted species is the most prominent among them. Herbicide resistance is the inherited ability of a plant to survive and reproduce following exposure to a dose of herbicide normally lethal to the wild type. Herbicide resistance is a worldwide phenomenon and number of resistant biotypes of weeds is increasing at an alarming rate. There are currently 480 unique cases of herbicide resistance globally in 252 plant species. Herbicide resistance in weeds is a product of evolution in cultivated fields, responding to the selection pressure laid by the use of such herbicides. Continuous use of the same herbicide or herbicides having same mechanism o...
Herbicide Resistance in Weed and Its Management-A Review
STATUS OF HERBICIDE RESISTANCE IN WEEDS AND THE WAYS TO MITIGATE IT FROM GLOBAL PERSPECTIVE, 2021
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.
Review on Herbicides Resistance and Their Mode of Action
PLANT ARCHIVES
Herbicides play a vital role in the reduction of crop yield losses by the use of effective weed control and weed interference capability, their ability to improving soil conservation practices. This review covering herbicide's resistance to specific weed and the mode of action of herbicides in the crops of agronomic fields. In most countries, input-intensive agriculture is adopted. For a better understanding, it is necessary to know about the mode of action of herbicides, management, organization, classification, and weed control capacity of herbicides. On other conditions, it also contributes insight into herbicide resistance; therefore it is a big problem of sustainable agricultural management. However, more use of herbicides, pesticides, and insecticides cause resistance among the weeds and it causing injury in plants and also removes beneficial plants in agricultural fields, industries, and management of lands. This review mainly focuses on the thorough determination of diff...
Status of Herbicide Resistance in Weeds and the Ways to Mitigate It from Global Perspective
Tropical Agroecosystems, 2020
Survivability of a few plants with natural resistance after herbicide application and their reproduction followed by herbicide application on each successive generation results in herbicide resistance and this phenomenon is rampant in present day agricultural fields. The study design is thus, focused on the overall status of herbicide resistance weeds and their distribution, mechanism of herbicide resistance in weed biotypes and the practices that are adopted and need to be adopted in order to curb the resistance development mechanism. The first herbicide resistance evidence was identified in triazine resistant to common groundsel (Senecio vulgaris). However, herbicide resistance was reported against 2,4-D from Hawaii as early as 1957. Currently, 512 unique cases (species×site of action) of herbicide resistant weeds with 262 species are on light globally. Herbicide-resistant weeds have been reported in 70 countries across 92 crops, with 619 scientists from around the world contribut...
Herbicide resistance in weeds and its management strategies
International Journal of Chemical Studies, 2020
Weeds are much older than crop cultivation for food, fuel, fibre and shelter. Weed management is a big task for production of various crops. At present time, herbicides are most popular and effective means for weed management due to their higher efficacy and time saving nature. But their continuous and indiscriminate use has created several problems like weed flora shift, herbicide resistance and environmental hazards. Out of these, herbicide resistance is most serious problem of present time. Currently there are 480 cases of herbicide resistance in 252 plant species. There are various types of herbicide resistance such as cross resistance, multiple resistance, partial resistance, full resistance etc. Herbicide resistance has become a major issue at world level, and number of resistant biotypes is increasing continuously at very rapid rate. Therefore, some alternate management practices such as cultural, mechanical and biological methods should be integrated in weed management program to combat this problem. A proper understanding of development and mechanism of resistance (altered target sites, rapid metabolism and sequestration) would help us for its management. With the help of various physiological and biochemical studies, some resistant screening techniques should be developed for yielding quick results. This paper provides information on status of herbicide resistance, development of resistance, factors affecting development of herbicide resistance in weeds, resistance mechanisms and its management.
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...

Weeds are one of the greatest limiting factors to efficient crop production. As a consequence of structural and financing problems the cultural condition of the soil deteriorates and weeds proliferate; many species are hard to kill. Therefore, for sustaining food grain production to feed ever-increasing population and ensuring food security, effective weed management is very essential. Despite advances in control technologies, weeds have retained their rank as the most damaging of crop pests because weed communities continue to adapt in response to new management measures. About 33% of crop loss is because of weed infestation. Changes in weed community composition are the result of selection pressures imposed by agronomic practices. The development of herbicide tolerant crops has been a major advance in weed control. Herbicide resistance is now widely recognized as the result of the adaptive evolution of weed populations to the intense selection pressure exerted by herbicides. To ov...
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.
