“…Light can induce the acceleration of nitric acid dissipation of in PAW. The half-lives of phenamacril and carbendazim in soil were found to be 17.1 days and more than 28 days respectively (Donau et al, 2019;Huang et al, 2020). The half-lives of propiconazole and epoxiconazole varied between 20 and 130 days depending on the soil type (Hollomon, 2017).…”

“…However, phenamacril has been reported to be moderately mobile in Jiangxi red soil, tending to remain in the soil phase and potentially leaching into groundwater . Research by Donau et al focused on its degradation characteristics, showing that phenamacril degrades slowly in activated sludge, which could pose a concern if the compound leaches into the surface water or groundwater or if production residues enter the wastewater system, indicating a potential risk of environmental migration. Tao et al reported on the absorption, accumulation, and metabolic characteristics of phenamacril in contaminated plants .…”

The fungicide phenamacril has been employed to manage Fusarium and mycotoxins in crops, leading to persistent residues in the environment and plants. Detecting phenamacril is pivotal for ensuring environmental and food safety. In this study, haptens and artificial antigens were synthesized to produce antiphenamacril monoclonal antibodies (mAbs). Additionally, gold nanoparticles coated with a polydopamine shell were synthesized and conjugated with mAbs, inducing fluorescence quenching in quantum dots. Moreover, a dual-readout immunochromatographic assay that combines the positive signal from fluorescence with the negative signal from colorimetry was developed to enable sensitive and precise detection of phenamacril within 10 min, achieving detection limits of 5 ng/mL. The method's reliability was affirmed by using spiked wheat flour samples, achieving a limit of quantitation of 0.05 mg/kg. This analytical platform demonstrates high sensitivity, outstanding accuracy, and robust tolerance to matrix effects, making it suitable for the rapid, onsite, quantitative screening of phenamacril residues.

Fusarium head blight (FHB) is an important fungal disease which can lead to serious yield losses and mycotoxin contaminations, the Fusarium strains have been found obvious resistance to many fungicides. Development of novel synergist is an important approach for addressing these challenges of postponing the development of pesticide resistance. In this study, the synergistic effect of Taxodium 'zhongshansha' essential oil (TZEO) was determined via the evaluation of synergistic ratio (SR) with three replicators under standard procedures. The best SR of 3.96 in laboratory which was observed when the weight ratio of TZEO and prothioconazole was 1 : 1 with the corresponding EC50 (half maximal effective concentration) value of Fusarium graminearum was 0.280 mg L− 1. Subsequently, an increase of 6.31% on the control effect to FHB index in field test was observed when compared to the treatment with prothioconazole alone, and the mycotoxin contamination was less than the limits of quantifications (LOQs) value satisfied to the detection of these mycotoxins which was 5 µg kg− 1 (DON, ZEN, 3-DON, and 15-DON) and 1 µg kg− 1 (OTA), respectively. It was also shown that the application of 20% TZEO EW led to a 20% reduction at least in the use of prothioconazole, which was calculated based on the control effect values of 86.41% and 90.20% between the treatments of 30% prothioconazole OD (225 g a.i ha− 1, recommend dosage) and 30% prothioconazole OD (180 g a.i ha− 1) + 20% TZEO EW (225 mL ha− 1), significantly. The initial residue of prothioconazole and prothioconazole-desthio was found to in-crease upon treatment with TZEO, which may play an important role in the synergistic effect on FHB. Moreover, none of the treatments posed a prothioconazole residue risk in the wheat grain and the environment. Finally, the essential oil was not found to have any negative influence on wheat growth, which was revealed by a study of the chlorophyll content. These results provide an important botanical synergist for use with prothioconazole to control Fusarium head blight, which will play a creative role to reduce the application of prothioconazole and postpone the development of resistance. Furthermore, in-depth study to the synergistic mechanism of this oil is necessary in our future research.
