“…dissipation kinetics comprises a mixture of the rates of photolysis, washing off, volatilization, hydrolysis, leaching, microbial degradation and other biotic/abiotic processes (Ruomeng et al, 2023;Shi et al, 2016). A similar study on the dissipation patterns of flusilazole and myclobutanil in apples was taken up by Hwang and Kim (2013) and biological half-lives of 6.2-6.7 and 13.3-24.8 days were reported for flusilazole and myclobutanil, respectively (Hwang & Kim, 2013).…”

“…The majority of farmers in the developing nations are unaware of the type, amount and application of pesticides as well as the effects of such acts because pesticides are exceedingly toxic for both humans and other living things. Pesticide residue dissipation kinetics comprises a mixture of the rates of photolysis, washing off, volatilization, hydrolysis, leaching, microbial degradation and other biotic/abiotic processes (Ruomeng et al, 2023; Shi et al, 2016). A similar study on the dissipation patterns of flusilazole and myclobutanil in apples was taken up by Hwang and Kim (2013) and biological half‐lives of 6.2–6.7 and 13.3–24.8 days were reported for flusilazole and myclobutanil, respectively (Hwang & Kim, 2013).…”

Apple, a major fruit of temperate Himalayas, is sprayed with chemical pesticides around 12 times during the cropping season. Various systemic and contact fungicides are applied for the management of major diseases. In order to manage disease, flusilazole 40 EC is frequently used. However, excessive chemical application has been found to be detrimental for consumer safety. Keeping in view consumer safety, risk assessment, the half‐life and waiting period for flusilazole 40 EC were evaluated on the Red Velox variety of apple. The QuEChERS (quick, easy, cheap, effective, rugged and safe) method and high‐performance liquid chromatography were adapted for sample processing and analysis, respectively. The recovery percentages of flusilazole at three fortification levels (0.04, 0.09 and 0.50 mg kg−1) were 98.85, 99.83 and 98.98%, respectively. Flusilazole at the recommended dose (80 g a.i. ha−1) left an initial deposit of 0.733 mg kg−1, which dissipated by 93.45% in 60 days and was non‐detectable beyond this period. Meanwhile flusilazole at double the recommended dose (160 g a.i. ha−1) left an initial deposit of 0.913 mg kg−1, which dissipated by 93.43% in 70 days and was non‐detectable beyond this period. Based on the maximum residue limit of 0.3 mg kg−1 as prescribed by the Codex Alimentarius Commission, a waiting period of 28.74 and 46.03 days was recorded for single and double doses, respectively. Moreover, in order to assess the consumer risk, theoretical maximum residue contributions (TMRCs) were derived using flusilazole residues (average and maximum) recorded at various time intervals and compared with the maximum permissible intake, which was found to be 0.42 mg per person per day. Based on the average per capita daily consumption of 6.76 g apple in India, the TMRC values were computed. Although the values of TMRC decreased below maximum permissible intake at the first day after application, indicating minimal consumer health risks, fruits sprayed with a double dose of flusilazole carried the risk even up to the tenth day after flusilazole application. The results of the present study will be valuable for safe and timely use of flusilazole on apple.

“…However, in recent years, the use of these chemical agents has raised concerns regarding their environmental impact and the emergence of resistant phytopathogen strains [7]. Since some of the synthetic fungicides have a long half-life, there is a danger of them persisting in the environment for extended periods of time and having a large ecological impact [8]. Moreover, they can influence and alter the activity of soil microorganisms other than phytopathogens, including plant growth-promoting microorganisms (PGPM) such as Bacillus bacteria [9,10].Gram-positive bacteria from the genus Bacillus are characterized by their rod-shaped morphology and the ability to form endospores, which enables them to adapt to various environments (e.g., soil and water), even in extreme conditions (such as high temperatures, pH fluctuations or exposure to toxic substances) [11,12].…”

This study aimed to evaluate how the combined presence of the synthetic fungicide azoxystrobin (AZ) and the biosurfactant-producing Bacillus sp. Kol B3 influences the growth of the phytopathogenic fungus Fusarium sambucinum IM 6525. The results showed a noticeable increase in antifungal effectiveness when biotic and abiotic agents were combined. This effect manifested across diverse parameters, including fungal growth inhibition, changes in hyphae morphology, fungal membrane permeability and levels of intracellular reactive oxygen species (ROS). In response to the presence of Fusarium and AZ in the culture, the bacteria changed the proportions of biosurfactants (surfactin and iturin) produced. The presence of both AZ and/or Fusarium resulted in an increase in iturin biosynthesis. Only in 72 h old bacterial–fungal co-culture a 20% removal of AZ was noted. In the fungal cultures (with and without the addition of the bacteria), the presence of an AZ metabolite named azoxystrobin free acid was detected in the 48th and 72nd hours of the process. The possible involvement of increased iturin and ROS content in antifungal activity of Bacillus sp. and AZ when used together are also discussed. Biosurfactants were analyzed by liquid chromatography with tandem mass spectrometry (LC-MS/MS). Microscopy techniques and biochemical assays were also used.

The expansion of food production is getting more important due to a rising world population, which is relying on food security on a regional and local scale. Intensive food production systems create a negative impact on the regional ecosystem because of agrochemical pollution and nutrient rich water discharges into nearby rivers. Furthermore, these systems are highly depending on regional water resources causing water scarcity and soil erosion due to the overexploitation of natural resources in general. The objective of this article is to review the water usage in the two most water intensive food production systems, agriculture and aquaculture showing lacking areas, like system management and climate change, which must be considered in the implementation of sustainable water footprint. In addition, the review includes an analysis if the combination of both production system into aquaponic food production and the possibilities of water saving. There are a variety of water footprint analyses for crop and aquatic animal production, but there is also a lack of information about the system management including irrigation systems, system cleaning processes, water substitution, pond removal, evaporation due to climate change and especially in aquaculture, the water footprint of industrial elaborated fish feed.
