“…Despite the economic importance and the considerable losses caused by the pathogen H. perniciosus , little is known about the genetic and pathogenic mechanisms underlying the interaction between H. perniciosus and the fungal host. Previous research has focused on the disease occurrence, genetic diversity, pathogenesis, pathogenicity, identification of disease resistance, and integrated control and management of the disease [3,4,7,8,9,10]. Genomic analysis of pathogens is also one of the most effective ways to obtain a full understanding of fungal pathogenesis at the molecular level [10].…”

The mycoparasitic fungus Hypomyces perniciosus causes wet bubble disease of mushrooms, particularly Agaricus bisporus. The genome of a highly virulent strain of H. perniciosus HP10 was sequenced and compared to three other fungi from the order Hypocreales that cause disease on A. bisporus. H. perniciosus genome is ~44 Mb, encodes 10,077 genes and enriched with transposable elements up to 25.3%. Phylogenetic analysis revealed that H. perniciosus is closely related to Cladobotryum protrusum and diverged from their common ancestor ~156.7 million years ago. H. perniciosus has few secreted proteins compared to C. protrusum and Trichoderma virens, but significantly expanded protein families of transporters, protein kinases, CAZymes (GH 18), peptidases, cytochrome P450, and SMs that are essential for mycoparasitism and adaptation to harsh environments. This study provides insights into H. perniciosus evolution and pathogenesis and will contribute to the development of effective disease management strategies to control wet bubble disease.

“…A similar study was performed by Du et al [46] with button mushrooms (Agaricus bisporus) growing on a substrate including wheat straw (78%), chicken manure (20%) and slaked lime (2%). In the substrate, the residue of pyriproxyfen (10% SC) was <0.1 mg/kg three days after application.…”

Since the 1990s, the insect growth regulator pyriproxyfen has been widely used worldwide as a larvicide in vector control and in agriculture to fight a very large number of pests. Due to its widespread use it is of first importance to know how pyriproxyfen behaves in the terrestrial ecosystems. This was the goal of this work to establish the fate profile of pyriproxyfen in soils and plants. Thus, in soil, pyriproxyfen photodegrades slowly but its aerobic degradation is fast. The insecticide presents a high tendency to adsorb onto soils and it is not subject to leaching into groundwater. On the contrary its two main metabolites (4′-OH-Pyr and PYPAC) show a different fate in soil. When sprayed to plants, pyriproxyfen behaves as a translaminar insecticide. Its half-life in plants ranges from less than one week to about three weeks. The review ends by showing how the fate profile of pyriproxyfen in soils and plants influences the adverse effects of the molecule on non-target organisms.

“…To date, several methods have been used to determine the residue behaviors of pyriproxyfen in tomato, 20 pepper, 21 citrus, 22 peach, 23 grape 24 and mushroom, 25,26 and residues have been reported in different fruits and vegetables. [27][28][29][30][31] However, no studies have reported the degradation behavior of pyriproxyfen and its metabolites in tea.…”

BACKGROUND Tea is one of the most popular drinks in the world. The growth of tea plant is inseparable from the control of pesticides on diseases and pests. Pyriproxyfen is used as a pesticide substitute to control insect pests in tea gardens, but little is known about its residue degradation. Here, we performed an integrative study of the degradation and metabolism of pyriproxyfen from the tea garden to the cup. RESULTS The dissipation half‐life of pyriproxyfen during tea growth was 2.74 days, and five metabolites PYPAC, PYPA, DPH‐Pyr, 5′′‐OH‐Pyr, and 4′‐OH‐Pyr were generated. The total processing factors for pyriproxyfen in green tea and black tea were 2.41–2.83 and 2.77–3.70, respectively. The residues of pyriproxyfen and its metabolites were affected by different processing steps. The total leaching rates of pyriproxyfen from green tea and black tea into their infusions were 9.8–12.3% and 5.3–13.8%, respectively. The leaching rates of the five metabolites were higher than that of pyriproxyfen and increased the intake risk. CONCLUSION To ensure safe consumption, the recommended maximum residue limit value of pyriproxyfen in tea can be set to 5 mg kg−1 and the pre‐harvest interval can be set to 5 days. © 2022 Society of Chemical Industry.
