ABSTRACT

In most farmlands, herbicides are used for weed control. Overuse and misuse of herbicides, along with a lack of novel active compounds, have resulted in herbicide-resistant weeds globally. Agriculture needs new weed control strategies despite efforts to improve existing ones. CRISPR/Cas9 gene-editing tools, together with developments in "omics" and cheaper sequencing technology, promise direct genetic control of weeds in farmlands Permanently or temporarily. There are many ways that biotechnology can be applied to better manage weeds. By introducing transgenes that promote herbicide resistance into the plant genome, crops have become herbicide-resistant. Biotechnology, has a significant impact on the speed and scope of global agricultural development. Nowadays, genetically modified crops (GMCS) are often referred to as "biotech crops”. Insect-resistance crop /IRC e.g. (Bt. cotton), pathogen-resistance crop (virus-resistance crop e.g., papaya), and herbicide-resistance crop /HRC (e.g., Roundup ready Soybean) are currently all included in the term "GMCS" globally. Parasitic weed-resistant crop variety, somatic hybridization, Plant Transformation etc used in development of GMCs.
