“…Opolot et al [19] reported the initial residue amount of sulfoxaflor to be greater in spinach than in Korean cabbage. A recent scientific report by [30] indicated that the initial concentration of picarbutrazox on cabbage was found to reach a maximum value of 13.72 mg/kg. The findings of this study are consistent with previous reports indicating that several factors, including evapotranspiration, plant metabolism, photolysis, crop growth rate, plant pore size, and crop sizes, can affect the initial deposition of pesticide residues in plants [1,22,32].…”

“…Several greenhouse studies on residue dis-sipation have demonstrated that prevailing environmental conditions, such as wind velocity, sunshine hours, and temperature plays a key role in fungicide dissipation [1,3,28]. Xu et al [30] highlighted that variations in wind velocity across different study regions affected the decrease in residual concentration of PCZ in banana foliage. Herein, although PCZ was applied uniformly across the different greenhouse locations, the rate of dissipation was found to be faster in spinach followed by that in cabbage and shallot.…”

“…The in-plant assessment and the initial residue amounts were evaluated to understand the fungicide residue behavior in the environment and analyzed crops. The initial residue concentration forms an important basis for establishing MRL for crops, and it corresponds to the residue level detectable after two hours of fungicide application [15,30]. The residue concentration of PCZ was found to be highest on day 0, ranging from 1.97-2.96, 1.46-1.60, and 5.82-6.26 mg/kg in cabbage, shallot, and spinach, respectively.…”

“…The half-live (DT 50 ) values obtained in this study are shorter than those observed in Jonagold apple, pomegranate, banana, and celery but longer than those in grapes and mango. For instance, the DT 50 of PCZ was found to be 13 days in Jonagold apples, 7.9-8.2 days in pomegranate, 13.9-23.3 days in bananas, 6.1 days in onions, and 8.7 days in celery [17,30]. Zhang et al [12] reported a half-life of 5.1-6.9 days in wheat straw.…”

Residue monitoring of propiconazole (PCZ) in cabbage, shallot, and spinach was conducted under multi-trial greenhouse conditions. This study aimed to understand the fate of the applied fungicide in these vegetables. Furthermore, the associated health risk of PCZ in leafy vegetables was assessed through dietary risk assessment.Commercially available PCZ (22% suspension concentrate) was administered thrice according to the OECD fungicide application interval guideline. The plant samples were extracted using a slightly modified QuEChERS technique and analyzed using gas chromatography-tandem mass spectrometry. The average PCZ recovery was between 84.5% and 117.6%, with a <5% coefficient of variance. The dissipation of PCZ residue in cabbage, shallot, and spinach after 14 days was 96%, 90%, and 99%, respectively, with half-lives of <5 days. Meanwhile, dietary risk assessments of PCZ residues in the studied vegetables

BACKGROUNDPicarbutrazox is a new tetrazolyloxime fungicide discovered in 2014 by Nippon Soda. It is mostly used to protect against Phytophthora spp. and Pythium spp. However, little is known of its inhibition spectrum, protective and curative activity, and systemic translocation in plants.RESULTSWhile picarbutrazox did not show obvious antifungal activity, it exhibited significant activity against oomycetes, including Phytophthora spp., Pythium spp. and Phytopythium spp.. The effective concentration for 50% growth inhibition (EC50) values of picarbutrazox against 16 oomycetes ranged from 3.1 × 10−4 and 7.27 × 10−3 μg mL−1. Furthermore, picarbutrazox could markedly inhibited the mycelial development, sporangia production, zoospore release, and cyst germination of Phytophthora capsici, with EC50 values of 1.34 × 10−3, 1.11 × 10−3, 4.85 × 10−3, and 5.88 × 10−2 μg mL−1, respectively. Additionally, under greenhouse conditions, the protective and curative activities of picarbutrazox at 200 mg L−1 (100%, 41.03%) against the P. capsici infection in peppers were higher than those of the reference fungicide dimethomorph at 200 mg L−1 (77.52%, 36.15%). High‐performance liquid chromatography analysis confirmed that picarbutrazox showed excellent systemic translocation in pepper plants.CONCLUSIONThe results showed that picarbutrazox markedly inhibited the important plant oomycete pathogens including Phytophthora spp., Pythium spp. and Phytopythium spp.. It also displayed excellent protective, curative and systemic translocation activity. Picarbutrazox thus has significant potential for preventing and controlling diseases caused by oomycetes. © 2024 Society of Chemical Industry.
