“…The ZnO-NPs suspension (250 mg/ L) was applied in four different ways: foliar spraying (T1), foliar soaking (T2), root soaking (T3), and soil soaking (T4). Methyl bromide fumigation was carried out for 26 days before transplantation: methyl bromide is hydrolyzed to methanol and the bromide ion, with a half-life of 20-26 days (Kaushik, 2021). The soaked soil was treated for 7 days before transplantation, and the uniform suspension was slowly poured into the mud pot containing the old orchard soil.…”

Apple replant disease (ARD) is a common disease in apple producing areas, and more and more evidence shows that soil-borne pathogens are the main factor. However, most of the drugs used to kill microorganisms are not friendly to the environment. Therefore, there is an urgent need to identify a method that can effectively eliminate these harmful microorganisms and to construct a microbial community structure that is conducive to plant growth in the soil. Herein, we use four different application technologies: foliar spraying, foliar soaking, root soaking, and soil soaking, to examine the inhibitory effect of zinc oxide nanoparticles (ZnO-NPs) on ARD. This study found that they all promoted the growth of Malus hupehensis Rehd. seedlings, and the plant height was 1.09 times, 1.15 times, 1.26 times, and 1.36 times higher that of the control, respectively. Soil soaking had the best promotion effect, and the changes in the soil microbial community structure after root soaking were analyzed. After treatment with ZnO-NPs, the abundances of Neocosmospora, Gibberella, and Fusarium were reduced, whereas the abundances of Tausonia, Chaetomium, and Mrakia were increased. The copy numbers of Fusarium solani and Fusarium oxysporum were 55.7 and 68.9% lower in the ZnO-NPs treatment group than those in the control group, respectively. This study found that after ZnO-NPs were applied to the soil, a new microbial community structure that was conducive to plant growth was formed to overcome ARD. In summary, ZnO-NPs, as a green chemical reagent, can overcome ARD, and it can also be applied to other continuous crops.

We present a new approach towards measuring methyl bromide (CH3Br) using a two-chamber photoacoustic sensor with the focus on suitable detector gas fillings. A MIR LED was selected as IR source. The absorbed spectral power in a photoacoustic detector filled with 100 vol.-% methane (CH4) and the response of this detector to CH3Br were simulated and compared with the response of a detector filled with 100 vol.-% CH3Br.

Education for Sustainable Development (ESD) is a key to achieving the Sustainable Development Goals. Initiatives and case studies have been reported to mainstream ESD in curriculum and textbooks, including ESD-integrated chemistry lessons. In Vietnam, although ESD has recently received much attention, the integration of ESD in teaching chemistry is still rare. This paper reports a participatory action research study, which developed and examined an ESD-integrated chemistry lesson on "Halogen derivatives" through the issue of fruit loaded with halogen-containing pesticides in Vietnam. The lesson was designed on Sjostrom's tetrahedron of chemistry education to achieve both the outcomes of Vietnamese general education and ESD learning objectives suggested by UNESCO. After the teaching intervention was applied to 83 students (11th grade) in a high school in Vietnam, both quantitative and qualitative data were collected through questionnaires (including Likert-scale items and open-ended questions) and interviews. Prepost comparison was used to analyze data about changes in students' understanding of SD. Data from Likert-scale items were analyzed using descriptive statistics, while other qualitative data were subjected to qualitative content analysis. Results showed that the students enhanced their perception of sustainable development concepts, engaged in making informed decisions, and perceived the lesson's relevance regarding individual, societal, and vocational dimensions. Notably, the data revealed that the pressure from school exams and traditional assessments might limit Vietnamese students' willingness to approach ESD-integrated lessons. The results suggested that initiatives integrating ESD into assessments and teacher education, should be implemented to facilitate the mainstreaming of ESD in Vietnam.
