“…Moreover, the maintenance of the viability of spores for future use is a real challenge ( Makowski and Mortensen, 1998 ). In this regard, it will be suggested that, besides using suspensions of fungal spores, identification, and commercialisation of phytotoxin-based herbicides/weedicides must be more emphasised on and preferred, since for such biochemicals storage/effectivity maintenance is easier, and its broad range of applicability is a plus ( Xu et al, 2019 ; de Souza Barros et al, 2021 ). Besides, due to constant usage of chemical herbicides, globally 263 species of weeds have become resistant to around 164 herbicides like atrazine, glyphosate, paraquat, 2,4-D, etc.…”

“…according to The International Herbicide-Resistant Weed Database. 2 This problem can be addressed with bioherbicides that are not known to be associated with de Souza Barros et al (2021) . Thus, usage of chemical herbicides is strongly discouraged, the replacement of which should be done by bioherbicides, that too more specifically phytotoxins are suggested over spore-formulations.…”

“…However, despite such the advancement in pathogenicity characterisation, the exact molecular pathway has not yet been depicted ( Dubrulle et al, 2020 ). Taking about the mode of action of the bioherbicides on the target plant, specific events like cellulase activity suppression, photosynthesis inhibition, glutamine synthase enzyme activity suppression, protoporphyrinogen oxidase enzyme action inhibition, and others ( de Souza Barros et al, 2021 ) are known to occur which eventually kills the weed.…”

“…In this context, fungal spore suspension/phytotoxin from different species has been considered as a potential bio-weedicide, that can be commercialised alongside the chemical herbicides. Moreover, recently there has been a growing concern regarding plants evolving into chemical herbicide resistant ones ( de Souza Barros et al, 2021 ). Here, in this article, we have elucidated why bioherbicides should be preferred over synthetic chemicals, and how eventually everyone may switch from using harmful synthetic weedicides to naturally obtained ones.…”

Invasive plant species are a major threat to biodiversity and agricultural productivity. Hence, efforts to manage these menace involves extensive and effective use of chemical herbicides amongst others. However, not only is the impact of control with chemical herbicides short-lived but also leads to negative impact on human health and environment due to non-target herbicide-drift and runoff from the sprayed areas. This has ushed in much-anticipated nature-based potential regulators of weed species, in an attempt to lower the utilisation of chemical herbicides. Mycoherbicides have been seen as a benign, eco-friendly, host-specific, and replacement for chemical herbicides. There are several noteworthy genera of fungus that have been proved to be effective against weeds. They either produce strong phytotoxins or are often used as spore/conidia-based solutions and applied as a spray in growth media. One of such potential genera is Colletotrichum Corda 1831. Compared to other potent fungal genera, with well-established roles in conferring herbicidal activities by producing competent phytotoxins, only a few species under genus Colletotrichum are known to produce fungal metabolites be used as phytotoxins. This article elucidates the current understanding of using spore suspension/phytotoxin of Colletotrichum as a weedicide. We also discuss the interaction between fungal metabolites release and Colletotrichum-target plant, from a molecular and biochemical point of view. This review article has been written to accentuate on the potency of Colletotrichum, and to serve as an eye-opener to consider this genus for further fruitful investigations. However, inconsistency associated with mycoherbicides in terms of viability and efficacy under field conditions, production of bioactive compound, slow natural dispersal ability, etc., have often reduced their utility. Hence, our study emphasizes on the need to do extensive research in elucidating more phytotoxins from necrotrophic phytopathogenic microorganisms with novel mode of action for field application.

“…Examples of herbicides applied worldwide include glyphosate, paraquat, and diuron. Among these, the most well-known is glyphosate; since its introduction in the 1970s, its use spread quickly, facilitated cropping, but also implied in the growing appearance of resistant weeds, resulting from a natural process of plant adaptation, and decreasing its efficacy [111][112][113]. An important alternative to minimize this problem, in addition to integration with other control methods, would be diversification in the use of herbicides, including others with different mechanisms of action [114].…”

The Challenge of Combining High Yields with Environmentally Friendly Bioproducts: A Review on the Compatibility of Pesticides with Microbial Inoculants

et al. 2021

Inoculants or biofertilizers aiming to partially or fully replace chemical fertilizers are becoming increasingly important in agriculture, as there is a global perception of the need to increase sustainability. In this review, we discuss some important results of inoculation of a variety of crops with rhizobia and other plant growth-promoting bacteria (PGPB). Important improvements in the quality of the inoculants and on the release of new strains and formulations have been achieved. However, agriculture will continue to demand chemical pesticides, and their low compatibility with inoculants, especially when applied to seeds, represents a major limitation to the success of inoculation. The differences in the compatibility between pesticides and inoculants depend on their active principle, formulation, time of application, and period of contact with living microorganisms; however, in general they have a high impact on cell survival and metabolism, affecting the microbial contribution to plant growth. New strategies to solve the incompatibility between pesticides and inoculants are needed, as those that have been proposed to date are still very modest in terms of demand.

BACKGROUNDEvaluation of herbicidal activity and identification of active compounds are important bases for the development of new botanical herbicides.RESULTSThis study confirmed that Symphoricarpos orbiculatus has high herbicidal activities against mono‐dicotyledonous weeds, including Echinochloa crusgalli, Digitaria sanguinalis, Amaranthus retroflexus and Portulaca oleracea. By bioassay‐guided isolation, 12 compounds were isolated and identified from S. orbiculatus for the first time, including iridoids: naucledal (K1), loganin (K2), loganigenin (K3), loganin acid (K4), glucologanin (K5) and vogeloside (K6), as well as flavonoids: quercetine (K7), luteolin (K8), nobiletin (K9), astragalin (K10), isorhamnetin 3‐d‐glucoside (K11) and rutin (K12). Biological assays showed that iridoids are the main active ingredients of S. orbiculatus. The compounds of K5 and K6 could inhibit both the root (IC50 = 37.54 and 38.91 μg mL−1, respectively) and shoot (IC50 = 42.78 and 45.72 μg mL−1, respectively) of Portulaca oleracea, which have a weeding toxicity similar to that of the commercialized plant‐based herbicide pelargonic acid. In addition, the results of pot culture assay showed that S. orbiculatus ethanol extracts had high fresh weight control effect against Digitaria sanguinalis and P. oleracea at the concentration of 40 g L−1. After 7 days, both the soil treatment and the stem and leaf spray method resulted in severe leaf necrosis and significant leaf etiolation.CONCLUSIONSymphoricarpos orbiculatus and its herbicidal active compounds have the potential to develop into botanical herbicides, and are first reported in the present study. © 2024 Society of Chemical Industry.
