“…Glyphosatetolerant crops, mainly soybean, cotton, corn and canola have become extensively cropped. The over-reliance on glyphosate in the commercial cultivation of engineered crops such as soybean and corn have triggered TSR in weeds in many areas [2,42]. There have been several reports globally on economically important weed species developing multiple resistance mechanisms and exhibiting multiple resistance across many herbicide classes [43][44][45][46][47].…”

Over the years, several agricultural interventions and technologies have contributed immensely towards intensifying food production globally. The introduction of herbicides provided a revolutionary tool for managing the difficult task of weed control contributing significantly towards global food security and human survival. However, in recent times, the successes achieved with chemical weed control have taken a turn, threatening the very existence we have tried to protect. The side effects of conventional farming, particularly the increasing cases of herbicide resistance agricultural weeds, is quite alarming. Global calls for sustainable weed management approaches to be used in food production is mounting. This paper provides detailed information on the molecular biological background of herbicide resistant weed biotypes and highlights the alternative, non-chemical weed management methods which can be used to prevent the development and spreading of herbicide-resistant weeds.

“…This generates an imbalance in carbon input and, consequently, results in a high concentration of phytotoxic compounds that act on metabolic pathways, such as shikimati-3-phosphate (Kruse et al, 2000;Pink;Vidal 2010;Krüger et al, 2013;Arango et al, 2014;Duke 2018). Brazil stands out for its massive agricultural use of glyphosate (De Moraes, 2019;Demichelli et al, 2020;Mendes et al, 2020;Mendonça et al, 2020;Melo et al, 2020), which leads to the contamination of several environmental matrices by this compound. As an example, Fernandes et al…”

The soil has been constantly exposed to a variety of contaminants and their mixtures in various concentrations, organic/inorganic chemical exposure, which mainly includes pesticides and their mixtures of monomers), which contaminate the soil to a greater extent and can also be transported within the soil and transfer the mixed contaminants, integrating into the food chain and passing through different trophic levels, causing health effects of organisms exposed to them. Pesticides are chemical compounds used to eliminate pests. They are chemical or biological agents, which weaken, incapacitate and kill pests. The emerging contaminant glyphosate (N-(phosphonomethyl)glycine) is widely used in agriculture in several countries. It is considered the most widely used herbicide in the world, as well as being one of the most harmful to human health. This compound is used to control harmful or invasive weeds. Glyphosate is the best-selling active ingredient in Brazil, with 195,056 tons sold in 2018. Brazil stands out for the massive agricultural use of glyphosate. An increasing number of countries have begun to restrict/ban the use of glyphosate-based products, such as Germany, Austria, Bulgaria, Colombia, and Costa Rica, among others, based on evidence already available on the direct incidence of glyphosate at various levels of the global ecosystem, as well as favoring the emergence of serious problems in human health. In this sense, the present study emphasizes the importance of knowing the main properties of pesticides and the study in search of efficient technological advances for the recovery of soils impacted by the use of glyphosate.

Weed Management is one of the most important crop intervention practice to counter crop loss. Different physical, mechanical, biological, and chemical methods are employed for the successful management of weeds. Among these chemical weed management practices focus on managing weeds using several chemical formulations which are commonly known as herbicides. Herbicides control the weed species through interference, mitigation, and disruption of the biochemical and physical processes of a cell. When herbicides are applied to a plant, it gets absorbed through plant surfaces and gets translocated to the specific site of action where it produces toxicity in the physiological and biochemical processes and ultimately check the growth and development of plant species. The sequential process from the introduction of herbicides to till it kills a plant is known as herbicides modes of action. The herbicides modes of action can be studied on nine different headings where the chemical group present in each herbicide acts on specific sites and interferes with the normal functioning of such sites ultimately checking the growth and development of a plant. This chapter is aimed at decoding the specific herbicide action in relation to its chemical family, translocation, action mechanism, and injury produced in the weed species.
