Microplastics(MPs) and cadmium(Cd) in soil have serious negative impacts on plant growth. As a bioremediator, Trichoderma viride may modulate the impacts of MPs and/or Cd on plant growth and heavy metal uptake. In this study, T. viride F7 was used to treat Cd-contaminated soil with and without the presence of polylactic acid MPs to investigate its effects on peanut growth, Cd uptake efficiency, and soil properties. Results showed that F7 increased soil pH,dissolved organic carbon, cation exchange capacity, microbial biomass nitrogen, and microbial biomass carbon, which resulted in increases of 2.10%–19.83% in peanut biomass and mitigated the negative effects of MPs and Cd on peanut growth. Trichoderma viride F7 reduced the soil bioavailable Cd and plant Cd concentrations by 16.68%–34.20% and 5.37%–25.84%, respectively. Regression path analysis showed that F7 could improve peanut performances by altering soil properties and reducing peanut Cd concentrations in MP-Cd-contaminated soil. Soil fungal community analysis indicated that the microbial community was altered via F7 inoculation, which antagonized Fusarium and promoted peanut growth. This study reveals the mechanisms of F7 in mitigating Cd contamination in the soil with the presence of MPs, which provides new ideas for managing MP-heavy metal-contaminated soil and improving soil health.

Maize(Zea mays L.) is an economically vital grain crop that is cultivated worldwide. In 2011, a maize foliar disease was detected in Lingtai and Lintao counties in Gansu Province, China. The characteristic signs and symptoms of this disease include irregular chlorotic lesions on the tips and edges of infected leaves and black punctate fruiting bodies in dead leaf tissues. Given favourable environmental conditions, this disease spread to areas surrounding Gansu. In this study, infected leaves were collected from Gansu and Ningxia Hui Autonomous Region between 2018and 2020 to identify the disease-causing pathogen. Based on morphological features, pathogenicity tests, and multilocus phylogenetic analysis involving internal transcribed spacer(ITS), 18S small subunit rDNA(SSU), 28S large subunit rDNA(LSU), translation elongation factor 1-alpha(TEF), and β-tubulin(TUB) sequences, Eutiarosporella dactylidis was identified as the causative pathogen of this newly discovered leaf blight. Furthermore, an in vitro bioassay was conducted on representative strains using six fungicides, and both fludioxonil and carbendazim were found to significantly inhibit the mycelial growth of E. dactylidis. The results of this study provide a reference for the detection and management of Eutiarosporella leaf blight.
