“…Direct effects of herbicides on fungal sporulation have been found to be variable and often species and dosage dependent [17]. Ray and Pandey [18], reported that while glyphosate stimulated sporulation of Alternaria alternate, 2-4-D inhibited same. Sporulation of F. pallidoroseum have also been shown to be inhibited by 2,4-D (at 1.0 and 0.25kg ai ha-1) and paraquat (at 0.75 and 0.19 kg ai ha-1) [12].…”

“…He suggested a judicious combination of chemical and biological control over time and space may help reduce the water hyacinth management costs by improving management efficiency. Ray et al [26] recommended integration of herbicide glyphosate at low doses with the insect and fungal biocontrol agents. However, at higher concentration the herbicides can have detrimental effect on the biocontrol agents.…”

“…Manual and mechanical control methods are used widely but they are not suitable for large infestations and are generally regarded as a shortterm solution [22]. Although chemical control methods are available that offer quick solution to the unwanted vegetation, they have their own limitations because of their non-target environmental impact [23][24][25][26]. There are other aspects such as toxicity to fish and other forms of life in the aquatic habitat, the deterioration of water quality from persistent chemical and dispersal of toxic chemicals through food chain [23,27].…”

Aquatic ecosystems throughout the world are threatened by the presence of invasive aquatic plants, both floating and submerged. Some of the aquatic species, such as water hyacinth (Eichhornia crassipes [Mart.] Solms), alligator weed, Alternanthera philoxeroides (Mart.), giant salvinia, Salvinia molesta D.S. Mitchell and water lettuce (Pistia stratiotes L.), Griseb. despite being relatively minor problems in their native range, have become major invaders of aquatic habitats in other parts of the world after having escaped from their natural enemies. Unchecked growth of aquatic vegetation is generally undesirable and reduces the value of the water resource. Despite adopting all control options including manual, mechanical, chemical and classical biological, the problem persists. The current weed management is oriented towards finding approaches that are effective in controlling the weed and reducing environmental contamination from herbicides. Plant pathogens have been gaining increasing attention and interest among those concerned with developing environmentally friendly, effective and compatible approaches for integrated management of the noxious weeds. This paper discusses some of the major microbial agents associated with aquatic weeds and their increasing role in integrated weed management.

“…Weeds are endowed with several growth-promoting features like fast reproduction, fast juvenile to the reproductive phase transition, plasticity to phenotype, ample seed production to continue generation, and extreme tolerance to unavoidable environmental conditions (Radosevich et al, 2007). The world's worst weeds belong to notable plant families like Poaceae, Cyperaceae, Asteraceae, Polygonaceae, Amaranthaceae, Brassicaceae, Leguminosae, Convolvulaceae, Euphorbiaceae, Chenopodiaceae, Malvaceae, and Solanaceae (Rana and Rana, 2019). Weeds have been classified variously based on different modes like (i) based on life span, (ii) based on ecological affinities, (iii) based on soil type, (iv) based on place of occurrence, (v) based on origin, (vi) based on cotyledon numbers, (vii) based on soil pH, (viii) based on morphology, (ix) based on nature of stem, (x) based on specificity, (xi) based on economic importance, (x) based on association with plants, (xii) based on site of predominance, and (xiii) based on habitat (Rana and Rana, 2019).…”

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.
