“…Similarly some species of Diplodia namely D. corticola, D. mutila, D. pinea and D. seriata have been reported as well-known pathogens of woody plants (Phillips et al, 2012). Recently D. corticola has been reported to cause stem cankers in Quercus rubra (Martin et al, 2016); D. mutila causing branch cankers in bristlecone Fir in California (Sims et al, 2016); D. bulgarica has been reported as a new pathogen on Apple trees in Iran and Bulgaria (Abdollahzadeh, 2015); D. seriata causing dieback and cankers in Prunus laurocerasus (Quaglia et.al, 2014). The diseases caused by Diplodia species have been associated with the onset of the stress factors and therefore it become imperative to isolate, identify and understand ecology and pathogenicity of fungi under diverse existence.…”

The present publication reports the mycobiota associated with Eichhornia crassipes (C Mart.) Solms (Pontederiaceae) infesting the Harike Wetland at Punjab in India and their potential application as a biological control agent based on their pathogenicity to the host plant. Of the 30 fungal isolates recovered from the infested samples of E. crassipes only one isolate #19BJSS caused 98% damage or infestation to the leaves during the in vitro leaf bioassay while it exhibited 100% plant death during the whole plant bioassay after 168 hours post inoculation (hpi). Morphological studies revealed it to be a member of Botryosphaeriaceae family which was further confirmed by Internal Transcribed Spacers (ITS) phylogenetic studies wherein the isolate #19BJSS clustered with Diplodia mutila. Botryosphaeria species have been predominantly associated with canker and die back diseases of woody plants. This is the first report of occurrence of Diplodia mutila #19BJSS as a pathogen of E. crassipes and for its potential as a biological control agent for the management of water hyacinth.

“…Prior infestation by some MB may also induce systemic resistance in plants against subsequent PFO infection ( Karban and Chen 2007). For instance, studies on interactions between the MB Eccritotarsus catarinensis and the necrotrophic PFO Acremonium zonatum, a biocontrol agent of water hyacinth, Eichhornia crassipes, suggested an initial development of a plant defense response to MB feeding, thus delaying infection by PFO (Ray and Hill 2016).…”

“…Firstly, the Miridae family is of tremendous economic importance since it encompasses both major crop pests (the incidence of some increasing as emerging pests on crops genetically modified with Bacillus thuringiensis (Bt) genes; e.g., Lu et al 2010;Sequeira 2019) and major natural enemies of pests (e.g., Pérez-Hedo and Urbaneja 2015), and to a lesser extent of weeds/invasive plants (e.g., Ray and Hill 2016). Regarding the former (MB as crop pests), all possible ways to manage them without synthetic pesticides (due to their adverse environmental and sanitary impacts) have to be sought, particularly by taking advantage of biological interactions within agroecosystems.…”

Miridae is the largest Heteroptera family, with a tremendous worldwide economic impact, both as pests and natural enemies. Unlike most Hemiptera, herbivorous and omnivorous mirid bugs are lacerate/macerate and flush feeders, not phloem feeders. Plant responses to damage by arthropods of this feeding guild therefore occur via jasmonic acid or ethylene signaling pathways rather than the salicylic acid pathway. Moreover, unlike most other Heteroptera that lay eggs on the plant surface, mirids insert their eggs in plant tissues, resulting in oviposition injury. Similarly, regarding phytopathogenic fungi and oomycetes, a distinction should be made between biotrophic fungi (triggering the salicylic acid pathway plant response), and necrotrophic and/or hemibiotrophic fungi or oomycetes (triggering jasmonic acid or ethylene pathway plant responses). In that respect, phytopathogenic fungi or oomycetes (PFO) differ from phytopathogenic viruses and bacteria, the former being all biotrophic while the latter are theoretically hemibiotrophic. Here, for the first time, we review tripartite interactions between mirids, PFO, and crop plants. The major deliverables are as follows: Five major interaction frameworks are identified: (i) crop plant infection by PFO mechanically facilitated by prior mirid infestation; (ii) crop plant infection by PFO hampered by prior mirid infestation via crop plant signaling; (iii) crop plant infestation by mirids facilitated by prior PFO infection via crop plant signaling; (iv) crop plant infestation by mirids hampered by prior PFO infection via crop plant signaling; (v) crop plant infestation by mirids and/or infection by PFO hampered by prior mirid infestation and/or PFO infection via crop plant resource quality alteration. PFO and mirids may also occur concomitantly, favored by the same conditions, i.e., climatic or linked to endogeneous factors (e.g., redox status) in crop plant. Instances from each framework are described, and highlighted interactions are examined in view of managing mirid-PFO complexes on crop plants.
