“…were closely related to the morphological characteristics of garlic chive and garlic scape. The whole leaf of garlic chive has a at structure and uffy surface, and pesticides adhere better to this surface than the smooth garlic scape surface (Bian et al 2020). During pesticide application, garlic grew in the soil, and the pesticide was applied directly to the garlic plant rather than to the garlic roots and soil.…”

To evaluate the residue levels of uopimomide, pyraclostrobin and its metabolite BF-500-3 in garlic ecosystems, supervised garlic eld trials with a commercial formulation (pyraclostrobin• uopimomide 30% suspension concentrate (SC)) were conducted in six regions of China according to the Good Agricultural Practices (GAP). The residues of uopimomide, pyraclostrobin and BF-500-3 in eld samples were determined using a QuEChERS method combined with high-performance liquid chromatography tandem mass spectrometry (HPLC-MS/MS). The average recoveries of all target compounds were 76-94% with relative standard deviations (RSDs) of 1.0-14.5% and limits of quantitation (LOQs) of 0.002 mg/kg. At the recommended pre-harvest interval (PHI, 10 d), the residues of uopimomide, pyraclostrobin and BF-500-3 were below 0.16, 0.77 and 0.12 mg/kg in garlic chive; below 0.027, 0.22 and 0.002 mg/kg in garlic scape; and below 0.002, 0.002 and 0.002 mg/kg in garlic, respectively. Dietary intake risks were calculated using risk quotients (RQs) based on eld residual data, toxicological data and dietary patterns. The chronic dietary risk quotients (RQc) of pyraclostrobin and uopimomide were 48.42% and 0.36%, respectively. The acute dietary risk quotients (RQa) of pyraclostrobin in garlic were 0.06-0.15%. These results indicated a low dietary risk for consumers. This study could provide scienti c guidance for the application of pyraclostrobin and uopimomide in garlic.

“…The analytical method was validated in terms of linearity, sensitivity, precision, accuracy, and matrix effect. − In order to eliminate the matrix effect, different concentrations of the standard solution were prepared with a blank apple matrix . The prepared standard solutions with different concentration gradients (0.01, 0.025, 0.05, 0.1, 0.25, 0.5, and 1 mg/L) were analyzed under the above analysis conditions, and the standard curves were drawn according to the ratio of the absolute amount of compounds to the peak areas.…”

A rapid, sensitive, and effective multiresidue analytical method was established to investigate the degradation rate and final residues of bifenthrin, bifenazate, and its metabolite bifenazate–diazene in apples, and the dietary risk of consumers was evaluated. The residues of bifenthrin, bifenazate, and bifenazate–diazene in apple samples from 12 different apple-producing areas of China were determined by high-performance liquid chromatography tandem mass spectrometry (LC-MS/MS). The average recoveries of the three compounds in apples were 88.4–104.6%, and the relative standard deviations (RSDs) were 1.3–10.5%. The limit of quantification (LOQ) for each compound was 0.01 mg/kg. Although the degradation half-lives of bifenthrin, bifenazate, and bifenazate–diazene were 17.8–28.9, 4.3–7.8, and 5.0–5.8 days, under good agricultural practice (GAP) conditions, the final residues of bifenthrin, bifenazate, and the sum of bifenazate and its metabolite bifenazate–diazene in apples were <0.01–0.049, < 0.01–0.027, and <0.02–0.056 mg/kg, respectively, which were lower than the maximum residue limit (MRL) in China. By comparing the deterministic model with the probabilistic model, the results of the probabilistic model at the P95 level (12.91–48.9% for bifenthrin, 17.48–52.01% for bifenazate including its metabolite) were selected as reasonable assessment criteria for chronic dietary risk, and the acute risk was at the P99.9 level (3.00–15.59% for bifenthrin). Although the exposure risk calculated by both the deterministic model and the probabilistic model was less than 100%, the risk to children is significantly higher than that of the general population. This suggests that in future research and policy making, we should pay more attention to the risk of vulnerable groups such as children.

Providing the population with food, agriculture with planting material, and raw materials for the processing and canning industries is an urgent problem of garlic production. Currently, not studied yet the passage and changes in the production processes of garlic plants under the influence of reproduction, which in some way constrains the industrial production of planting material and marketable products in general. Studies on the impact of reproductions on changes in physiological state, plant resistance to disease and productivity were conducted during 2017–2020 in the research field of the Department of Vegetable Growing, Uman National University of Horticulture. During the biometric measurements, a significant change in the variation of approbation traits (height of the plant and scape, number of leaves and its size, number and weight of bulbils, cloves in the bulb) of garlic plants under the influence of reproduction, ie variety testing must indicate what is this generation. There was a significant decrease in the concentration of chlorophyll and the antioxidant enzymes activity in the leaves in III–V reproductions, which significantly affected the productivity and tolerance of plants. Indicators of plant damage disease on a natural infectious background indicated a sharp decrease in the resistance of plants of the Sofiivskyi cultivar in IV–V reproductions, Prometei and Lyubasha cultivarss in III–V. It was found that in the cultivar Sofiivskyi the largest mass of the bulb was formed in the first reproduction, while in the cultivars Prometheus and Lyubasha – in the second, and its gradual decrease to 21.2 % in the fifth reproduction. Yield had a similar trend, where the maximum reduction in yield was observed at 18.2; 28.0 and 17.0 % in the cultivars Sofiivskyi, Prometei and Lyubasha. The developed scientifically substantiated provisions will allow to increase efficiency of selection process and production of seed material.
