“…In every cropping system, weeds present multidimensional problems, competing for water, space, nutrients, and sunlight that negatively affect crop production [ 5 ]. The most severe impact among all is the loss of quality and quantity of the final product [ 6 ]. Weeds not only harbor pathogens and insects that infect crop plants, but they also damage native habitats, eventually threatening native animals and plants [ 7 ].…”

Weeds have continually interrupted crop plants since their domestication, leading to a greater yield loss compared to diseases and pests that necessitated the practice of weed control measures. The control of weeds is crucial to ensuring the availability of sufficient food for a rapidly increasing human population. Chemical weed control (herbicides) along with integrated weed management (IWM) practices can be the most effective and reliable method of weed management programs. The application of herbicides for weed control practices calls for the urgency to develop herbicide-resistant (HR) crops. Recently, genome editing tools, especially CRISPR-Cas9, have brought innovation in genome editing technology that opens up new possibilities to provide sustainable farming in modern agricultural industry. To date, several non-genetically modified (GM) HR crops have been developed through genome editing that can present a leading role to combat weed problems along with increasing crop productivity to meet increasing food demand around the world. Here, we present the chemical method of weed control, approaches for herbicide resistance development, and possible advantages and limitations of genome editing in herbicide resistance. We also discuss how genome editing would be effective in combating intensive weed problems and what would be the impact of genome-edited HR crops in agriculture.

“…The process may include targeted and site-specific weed control, selection of weed seeds, different herbicide application (depending on weed distribution, spatial arrangement and soil properties), destruction of weed seeds over predation and microbial loss, nano herbicides, and optical spraying techniques. Advanced vision-guided robotics that can be adopted for site-specific weed management (SSWM) are transgenic herbicide-resistant crops, weed control and spraying robots, decision support systems, and pattern recognition modelling [33]. Implementing these technologies will help prevent unwanted species and improve existing weed management systems [34].…”

Weed Detection in Rice Fields Using Remote Sensing Technique: A Review

et al. 2021

This paper reviewed the weed problems in agriculture and how remote sensing techniques can detect weeds in rice fields. The comparison of weed detection between traditional practices and automated detection using remote sensing platforms is discussed. The ideal stage for controlling weeds in rice fields was highlighted, and the types of weeds usually found in paddy fields were listed. This paper will discuss weed detection using remote sensing techniques, and algorithms commonly used to differentiate them from crops are deliberated. However, weed detection in rice fields using remote sensing platforms is still in its early stages; weed detection in other crops is also discussed. Results show that machine learning (ML) and deep learning (DL) remote sensing techniques have successfully produced a high accuracy map for detecting weeds in crops using RS platforms. Therefore, this technology positively impacts weed management in many aspects, especially in terms of the economic perspective. The implementation of this technology into agricultural development could be extended further.

“…Weeds are the main factors, responsible for the low production of crops (Hussain et al, 2020). Hence, weed management is very important in sustainable agriculture for integrated weed management based on production that is environmental friendly and economical (Matloob et al, 2019;Aziz et al, 2021).…”

Vegetables are consequently experiencing great yield losses due to weed infestation. Weed management is extremely important for sustainable crop production in all cropping systems. This review paper aimed to provide general information and alternative recommendations for the management of Parthenium hysterophorus weed by chemicals, adjuvants and plant extracts in okra. Different strategies have been used to control parthenium, but no single management solution is sufficient to handle parthenium; hence, different management options need to be combined. Only an integrated approach will achieve effective control over this weed. In areas where parthenium natural enemies are absent, chemical control is an important method of managing this weed. In the control of this plant, the use of chemical herbicides such as chlorimuron ethyl, glyphosate, atrazine, ametryn, bromoxynil and metsulfuron are considered to be efficient. Moreover, various plants have allelopathic potential and attempts have been made to use them in parthenium control. Three allelopathic grasses, namely, Achyranthes aspera, Syzygium cumini and Acacia nilotica are able to minimize the plant growth and inhibit early seedling growth of exotic weed P. hysterophorus. The results recommend that the control of parthenium in okra and other summer vegetables using chemical herbicides with single and combination mode of action is still effective compared to the use of plant extracts. The use of herbicides by adding adjuvants has the potential to minimize the use of excessive herbicides.
