), antagonism (Ant.) (Chvre etal., 1997; Green, 2009). increased the MN frequency only when the lowest concentration (0.71mg/L) was tested on R.arenarum tadpoles (Nikoloff etal., 2014). The little available data suggest that herbicides can increase organic acid exudation and attract acidophilic microorganisms and stimulate denitrification.
The richness was highest in the R-IM treatment and was higher in the S-IM treatment compared to the control, while the bacterial community in the S-IM treated group appeared to be the most diverse (Qian et al., 2015b). (2014) demonstrated that tadpoles exposed to the neonicotinoid insecticide imidacloprid (25.0mg/L) for 96h showed an increased frequency of MNs, while no other ENA was induced. Approximately 31 parent herbicide residues belonging to different chemical groups were detected in more than 768 water samples from 18 countries (Brazil, Burkina Faso, Canada, China, Ethiopia, France, Germany, Iran, Lebanon, Luxembourg, Portugal, Slovenia, Spain, USA, Vietnam, and West Bengal). In another study, herbicide zytron, o-2,4-dichlorophenyl-methyl isopropyl phosphoramidothioate, while itself did not show any adverse effect on molds, actinomycetes, and soil bacteria, its degradation product, 2,4-dichlorophenol, was found to be toxic to molds (Fields and Hemphill, 1996).
Munoz-Leoz et al. Martinez-Toledo et al. The herbicide mixture of atrazine+nicosulfuron was efficient for controlling Bidens pilosa (Asteraceae), Brachiaria decumbens, Brachiaria plantaginea and Digitaria horizontalis (Poaceae), and Ipomoea grandifolia (Convolvulaceae) (Silva etal., 2005) (Table6). These include herbicides for killing plants, insecticides for killing insects, fungicides for killing fungus, and bactericides for killing bacteria. 2005). The development of herbicide-tolerant (HT) crops certainly allowed the farmers to simplify their weed control programs. It is highly soluble in water (10.5g/L) and has a high dissociation constant (pKa=2.32) and a low partitioning coefficient (Log P=3.2) (PPDB, 2007). Since herbicides are the main weed management toolboxes, this system often exerts strong selection pressures for the development of resistance in weeds. (2009) pointed out that high-altitude populations appear to be locally adapted to better resist UV-B genotoxicity, as they showed the lowest MN numbers. For instance, twenty-eight herbicide residues were detected in the water samples from Portugal with a concentration range of 0.0020.27g/L (Palma et al., 2009, 2014). A commonly used member of this class is the herbicide imazethapyr (CAS no. In the recent study by Monteiro etal. It is therefore important to carry out studies to determine how the effects of pollen-mediated gene movement can be eliminated especially from volunteer plants. Prez-Iglesias etal.

Effect of glyphosate-based herbicide formulations on potentially beneficial, pathogenic, soil rhizosphere bacteria and other organisms. Triazophos, combined with chlorothalonil and copper oxychloride, caused phytotoxicity in adult Carica papaya (Caricaceae) plants and, when associated with thiabendazole, reduced their growth (Vieira etal., 2003). Within the last few years, the use of cutting-edge genomic techniques allowed the unraveling of some of the hidden mysteries regarding plant pesticide interactions.
A concentration range of pirimicarb 0.0050.39mg/L. Though conservation agriculture dramatically increased productivity in Australia, the consequence is the widespread evolution of HR weeds across grain-producing regions (Broster etal., 2013; Owen etal., 2014). Compared with S-IM, the R-IM was more effective in damage of maize growth with the shorter shoot and root length, lower dry weight, and more obvious chlorosis at equal concentrations. Fourteen herbicide residues were detected in the water samples from Spain with a concentration range of 1.1632.32g/L (Ccanccapa et al., 2016). Thus, Brassica napus was shown to hybridize, at a very low frequency in the open environment, with Indian mustard (Brassica juncea), Ethiopian mustard (Brassica carinata), black mustard (Brassica nigra), annual wall rocket (Diplotaxis muralis) and wild radish (Raphanus sp.) R-IM appeared almost two times more toxic than S-IM to the root during the time course experiment. They made various functional community profiles at different tebuconazole concentration, and it was observed that tebuconazole application suppressed soil microbial biomass and activities. Although glyphosate was earlier thought to be the bullet-proof herbicide, this paradigm was changed in 1996 with the discovery of GR annual ryegrass in Australia (Pratley etal., 1996). Results of a prospective cohort study with 57,310 pesticide applicators in USA indicated associations of two imidazolinone herbicides (imazethapyr and imazaquin) with bladder cancer (Koutros et al., 2015). Moreover, long-term application of pesticide may lead into the dominance of only few functional microbial groups, thereby affection the overall community structure and related biological processes of soil (Lupwayi et al., 2009b).
The addition of insecticides to herbicides in tanks can modify plant tolerance and reduce the selectivity or capacity for weed control (Gassen, 2002). Lajmanovich etal. Application of three insecticides lindane, unden, karate and a fungicide dithane in vegetable crops resulted in decline of both fungal and bacterial populations; however, the reduction was more pronounced in fungal population as compared to bacterial (Glover-Amengor and Tetteh, 2008). To date, glyphosate has been detected in many water bodies, including drinking water, due to possible spillage, runoff, and leaching. Of the other pesticides studied in these publications imazethapyr, a pyridine herbicide, (Koutros et al., 2009) and EPTC, a thiocarbamate herbicide, (van Bemmel et al., 2008) have been shown to have significant positive associations with colon cancer risk. Table5. 
(2004) observed that biodegradation of pesticide isoproturon favored bacterial growth while suppressed actinomycetes and fungi. Meftaul, Mallavarapu Megharaj, in Environmental Pollution, 2020. (2015b), which examined the enantioselective effects of IM on the microbial community in the root structure of A. thaliana, showed that the abundance of 16S rRNA gene copies per mg of fresh weight root increased more after a 4-d exposure to the R-IM enantiomer than to S-IM. The distribution, sale and use of an unregistered pesticide is a violation of federal and/or state law and is strictly prohibited.

In addition, several beneficial bacteria such as Campylobacter spp., Enterococcus faecalis, Enterococcus faecium, Bifidobacterium adolescentis, Bacillus badius and Lactobacillus spp. Further, on the basis of ARDRA pattern, it was observed that the overall genetic diversity of the bacterial community decreased under this chemical stress (Wang et al., 2008). Such a pollen escape phenomenon can be minimized by giving much attention to different parameters such as vegetative propagation (apomixes), self-fertilization, male sterility and seed sterility (Liu etal., 2013). Similarly, Duah-Yentumiand Johnson (1986) reported that some pesticides such as carbofuran iprodione (fungicide), 4-chloro-2-methylphenoxy-acetic acid (MCPA), and simazine (herbicides) showed either no or very little detrimental effects on soil microbial biomass, while in the same soil, other pesticides such as carbosulfan (insecticide), vinclozolin (fungicide), and paraquat (herbicide) produced a significant decline in microbial biomass. Mixtures of fungicides and insecticides were beneficial for the treatment of soybean seeds (Balardin etal., 2011) or in cucurbit crops such as melons (Cardon etal., 2016). Weeds resistant to herbicides is an inherited ability of a plant to survive an application of the herbicide at the recommended use (Gressel and Roehrs, 1991). These residues were 2,4-D, acetochlor, alachlor, ametryn, atrazine, bentazone, butachlor, clomazone, cyanazine diuron, hexazinone. Another significant frequency of MN and ENAs was evidenced in the study by Babini etal. Species of Amaranthus, Commelina, Ipomoea, Cyperus as well as annual grasses were more problematic weeds in glyphosate-tolerant cotton and soybean in 11 states of Brazil (Culpepper etal., 2006). (2018) using Chromium, a significant difference in MN frequency was detected between the negative control and all the groups treated with dose-dependent effect. Similarly, a decline in bacterial, fungal and actinomycetes communities, as well as soil DHA was reported following the application of herbicides atrazine, primeextra, paraquat, and glyphosate (Sebiomo et al., 2011). Moreover, it has been detected in groundwater with a maximum concentration of 1.42g/L (Rendon-von Osten and Dzul-Caamal 2017). It is a violation of federal and state/provincial law to use any pesticide product other than in accordance with its label. Thus, the intensive and repeated application of a single herbicide leads to resistance in weed species, as reported for GM-RR corn and GM-RR soybeans (Marshall etal., 2000). However, dispersing agents and constant stirring may reduce precipitate formation (Petter etal., 2012).
The effects of each enantiomer were partly linked to organic acid exudation from plant roots, but the precise mechanisms explaining the reported enantioselective IM toxicity are still unknown. For example, Glover-Amengor and Tetteh (2008) reported that yield of unden-treated vegetable crops was as higher as compared to lindane treated crops in similar conditions and soil as unden degradation led to release of N, thereby increasing its concentration in soil. (Jasieniuk etal., 1996) as well as environmental conditions (Vila-Aiub etal., 2014). Microorganisms those survive the negative influence of pesticide may be genetically modified in a way that is no longer beneficial to the soil ecosystem and become resistant to the pesticide intended to kill them. and C.botulinum (Krger etal., 2013a). Nevertheless, there is growing concern for potential toxicity to aquatic organisms due to high solubility in water and high dissociation constant (see above). In cattle, Clostridium botulinum-associated diseases are in two forms, an acute form of botulism that occurs after the uptake of botulinum neurotoxin performed in feeds causing flaccid paralysis and death by respiratory failure, and a chronic form characterized by weakness, local paralysis, emaciation, muscular stiffness and varying degrees of recumbency (Krger etal., 2013b). Ki-Hyun Kim, Shamin Ara Jahan, in Science of The Total Environment, 2017. By continuing you agree to the use of cookies. Growing imidazolinone-tolerant canola greatly improved the profits by avoiding the yield-penalty linked with TT canola, but many imidazolinone-resistant weed populations developed particularly in Australia (Hudson and Richards, 2014), thus making this Clearfield technology less attractive. must be evaluated for effective control of volunteers. (1998) and Das and Mukherjee (2000) observed that the population size of sensitive communities will decrease, while an increase in the population of microbes capable to withstand the elevated concentration of pesticides can be observed. During the recent years of the traditional application of this herbicide, only a very limited number of weeds developed resistance to glyphosate (Powles, 2008a,b). Marcelino Benvindo-Souza, Lia Raquel de Souza Santos, in Chemosphere, 2020. A high frequency of MNs was observed when tadpoles of B.pulchella were exposed to15 and 30mg/L of imidacloprid for 48h, and in 96h of exposure only 15mg/L promoted an increase in the frequency of micronucleated cells (Arcaute etal., 2014). (2015) emphasize that the number of MNs resulting from UVB exposure was much higher when compared to UVA at 48h and 7 days after treatments, demonstrating the high mutagenic potential of these lower wavelengths of UV solar radiation. The effect of Cadmium and Lead was explored for induction of MN in tadpoles (Bufo raddei), and a significantly high rate was observed (Zhang etal., 2007). According to an analytic cohort study, women living in counties with the highest mean radon concentrations (>148Bqm3) had a significantly enhanced risk of hematologic cancer compared to those living in counties with the lowest (<74Bqm3) radon levels (HR=1.63, 95% CI:1.232.18) (Teras et al., 2016). (1998) observed that application of fungicides captan at dose rates of 2.010.0kg/ha enhanced denitrifying and total culturable bacteria, while total culturable fungal populations, nitrifying bacteria, aerobic nitrogen-fixing bacteria and nitrogenase activity were significantly decreased at the same concentrations, suggesting that soil microbial communities have varying tolerance for different pesticides. However, evidence of carcinogenicity was noted by the U.S. Environmental Protection Agency (US EPA) and/or Canadian Pest Management Regulatory Agency (PMRA) in animal toxicity studies for alachlor, carbaryl, metolachlor, pendimethalin, permethrin, and trifluralin, thus supporting the biological plausibility of associations observed from these pesticides. The cadmium was also tested (Patar etal., 2016) in Fejervarya limnocharis tadpoles, whose time of exposure (48h treated with 0.2mg/L and 72hat 0.3mg/L) induced the incidence of MN. Approximately 31 parent herbicide residues belonging to different chemical groups were detected in more than 768 water samples from 18 countries (Brazil, Burkina Faso, Canada, China, Ethiopia, France, Germany, Iran, Lebanon, Luxembourg, Portugal, Slovenia, Spain, USA, Vietnam, and West Bengal). Pesticides consist of a large group of chemical agents that attempt to eliminate destructive biological agents in agriculture. Root was more sensitive than the shoot to IM during the treatment. Copyright 2019 Generic Crop Science LLC. Willowood Imazethapyr 2SL is a contact post-emergence herbicide for the control of certain broadleaf weeds and yellow nutsedge in alfalfa, beans, peas, peanuts, soybeans and other select registered crops.. Ferreira etal. Table5. intoxication in rice by the insecticides cypermethrin, thiamethoxam and bifenthrin/carbosulfan mixed in a tank with the herbicides cyhalofop-butyl, Pesticide residues in drinking water, their potential risk to human health and removal options. Radiation was curiously the first xenobiotic evaluated by the test of MN in anurans (R.catesbeiana tadpoles), where it was found that the gamma ray favors the linear increase in the frequency of MNs in tadpoles depending on the doses 0.5 to 3.0 gamma rays (Krauter etal., 1987). On the other hand, the fungicides azoxystrobin or trifloxystrobin plus protioconazole mixed with the herbicides bromoxynil or 2,4-D can damage wheat leaves (Karkanis etal., 2018). Poultry eggs and meat are one of the main sources of human foodborne infections caused by species of Salmonella like S.enteriditis, S. typhimurium and S.gallinarum which are highly resistant to glyphosate (Authority, 2009; Shehata etal., 2013).
Additionally, seven herbicide metabolites (deethylatrazine, deisopropylatrazine, deisopropylatrazine, desethylatrazine, desethyl terbuthylazine, terbumeton-deethyl, terbuthylazine deethyl, and 2 hydroxy-terbutylene) were detected in the water samples. Such an extent in the occurrence of GR weed populations in Australia indicates that many herbicides that were effective earlier are no longer useful now. (2005) of the endosulfan insecticide, the MN frequency measured in erythrocytes of B.pulchella tadpoles showed no dose dependence at different concentrations (2.5, 5 and 10g/L). Martinez-Toledo et al. Mixtures of different pesticide classes may also affect plant absorption, translocation, and metabolism (Hartzler etal., 2000). In a study focusing on long term genotoxic effect on rabbits exposed to the neonicotinoid pesticide imidacloprid (IMI), there were statistically significant differences in the frequencies of binucleated cells with micronuclei between control and exposed groups (Stivaktakis et al., 2016). These residues were 2,4-D, acetochlor, alachlor, ametryn, atrazine, bentazone, butachlor, clomazone, cyanazine diuron, hexazinone, imazethapyr, isoproturon, glyphosate, linuron, mecoprop, metoalachlor, metribuzin, molinate, pendimethalin, prometon, propanil, propazine, simazine, tebuthiuron, terbumeton, trifluralin, terbuthylazine, terbutryn, and pretilachlor. Since the predictions about the environmental consequences of pesticide applications in agriculture are challenging (Ramakrishnan etal., 2019), better insights into the development of antimicrobial resistance in soil bacteria are greatly needed. Because of its non-selective nature, glyphosate is applied for controlling a wide array of weeds before crop sowing/transplanting or between the established rows of vine crops, nuts and trees (Duke and Powles, 2009). Two residues were detected in the water samples from Vietnam and France, whereas one residue was detected in the water samples from Burkina Faso, West Bengal, Ethiopia and Iran. Seven herbicide residues were detected in the water samples from Lebanon with a concentration range of 0.261.73g/L (Chaza et al., 2018) and from Germany with a concentration range of 1.2279.02g/L (Stehle et al., 2019).
It is believed that overreliance on herbicides of the same chemical class or targeting the same site of action is a major contributor to the development of herbicide resistance (Powles and Gaines, 2016). Eight herbicide residues were detected in the water samples from Vietnam with a concentration range of 0.00010.47g/L (Toan et al., 2013; Wan et al., 2021).

Aficida induced damage to DNA at the chromosome level by increasing the frequency of MNs and other ENAs, ie, lobed and carved nuclei and binucleate cells (Natale etal., 2018).
