“…Biochar is a stable form of carbon that can be produced from the pyrolysis process of waste straw under limited oxygen conditions and relatively lowtemperature conditions of incineration (< 700 °C) (Joseph et al 2010). This material has gained great attention for agricultural applications (Iftikhar et al 2018), environmental protection (O'Connor et al 2018), and energy (Dong et al 2018), as well as other areas in recent years. Biochar is a hard-to-degrade material in its natural state (Leng and Huang 2018), and has been produced from terra preta for hundreds or even thousands of years (Glaser et al 2002).…”

Effects of aging after pyrolysis were tested relative to the physicochemical characteristics of peanut straw biochar. Biochar was prepared at pyrolysis temperatures of 350 °C, 500 °C, and 650 °C; then, it was freeze-thawed and dry-wet aged. The physicochemical characteristics of the fresh and aged biochar were analyzed. The results showed that the pyrolysis temperature, ambient temperature, and humidity affected the physicochemical characteristics of the biochar. With the increase of pyrolysis temperature, the yield and surface acidic functional groups of the fresh biochar decreased, whereas the ash content, C content, pH, specific surface area, and mesoporous volume of the fresh biochar increased. The aging treatment increased the acidic functional groups content in the biochar and reduced the aromatic functional groups content, which decreased the pH value of the biochar. The aging treatment increased the specific surface area and pore volume of the biochar, and the effect of freeze-thaw aging was greater than that of dry-wet aging. The aging treatment also destroyed the complete shape of the fresh biochar, and reduced its stability. After the aging treatment, the C content of the biochar decreased, whereas the O content increased, due to oxidation of the biochar.

“…Other conspicuous postharvest citrus diseases include brown rot that occurs due to Phytophthora, green mold due to Penicillium digitatum, and blue mold through Penicillium italicum. Usually, plants become infected by soil-borne fungi and bacteria that cause loss of eshy tissue during the time or soon before harvest [11]. During packaging, common air molds like Penicillium species may in ltrate vulnerable tissues and decrease the value of the fruit [12,13].…”

Background: In all of Pakistan's citrus-growing regions, losses related to fungi that cause infections of citrus fruits were investigated. However, the Khanpur city of the Haripur district, a significant citrus-growing area in Pakistan, has not addressed this issue. Citrus fruit quality and quantity deteriorate as a result of various fungi impairing their quiet standards, resulting in economic losses. Results: The current investigation involves three steps that are morphological, pathological, and molecular identification of the fungal pathogens linked to citrus fruit diseases. Firstly the pathogens from infected fruit samples were isolated by culturing them on potato dextrose agar (PDA) for morphological characterization. Secondly, the 5.8S rDNA molecular sequencing was used to identify the crucial species at the molecular level. The results showed that they belonged to the seven important genera of Colletotrichum, Alternaria, Aspergillus, Botryosphaeria, Lasiodiplodia, Penicillium, and Fusarium. And thirdly the three different citrus cultivars were subjected to pathogenicity assays to identify the most resistant variety to fungal diseases. Conclusions: Current work associated with the comprehension of disease development points towards effective managerial practices in the form of a cost-effective spray program. Furthermore, the findings are indicative of the need for biological and physical pre-harvest management interventions to increase storage and marketability.

“…Natural biological degradation modes are preferable, as they are proficient, particularly cost‐effective, and environment friendly. For example, numerous organisms have been consolidated in the rhizospheric zone of various plants for the productive expulsion of several contaminations from soils [8–10]. Regardless of the need for remediation strategies for environmental protection, no reports have been produced so far on the behavior of this pesticide toward microorganisms [11,12].…”

The current research is a pioneer in the evaluation of isopyrazam biodegradation, which has been performed utilizing soil‐isolated microbes. Biodisintegrative assays of pure fungal strains, namely Aspergillus flavus (AF), Penicillium chrysogenum (PC), Aspergillus niger (AN), Aspergillus terreus (AT), and Aspergillus fumigatus (AFu), and bacterial strains, namely Xanthomonas axonopodis (XA) and Pseudomonas syringae (PS), were utilized. Initial isopyrazam concentration (10 mg/L) was prepared with an individual microbial suspension and monitored for 35 days. Isopyrazam biotransformation was analyzed quantitatively and qualitatively by UV–visible spectrophotometery and gas chromatography–mass spectroscopy. P. syringae (R2 = 0.90) and X. axonopodis (R2 = 0.88) displayed maximal potential to metabolize the fungicide (86% and 80%, respectively) while forming intermediate metabolites, including 3‐difluoromethyl‐1‐methyl‐1H‐pyrazole‐4‐carboxylic acid ((S)‐9‐hydroxy‐9‐isopropyl‐1,2,3,4‐tetrahydro‐1,4‐methanonaphthalen‐5‐yl)‐amide, 3‐difluoromethyl‐1H‐pyrazole‐4‐carboxylic acid, and 3‐difluoromethyl‐1‐methyl‐1H‐pyrazole‐4‐amide. Isopyrazam degradation by all strains, AT, PC, AFu, AN, AF, XA, and PS, was found to be 11%, 18%, 21%, 21%, 18%, 30%, 80%, and 86%, respectively, after 35 days, elucidating the effectiveness of all the utilized strains in degrading isopyrazam at varying rates. The descending order of half‐lives (days) obtained is as follows: AT (56.8) > PC (44.7) > AFu (40.7) > AN (39.6) > AF (32.6) > XA (28.1) > PS (21) days. Current research can influence imperative and significant environment‐friendly bioremedial strategies for xenobiotic eradication from the ecological compartments.
