“…The experiments were performed in two variants, in which the effects of foliar application or incrustation of fungicides were examined. Variant 1 — presowing seed treatment was conducted because mildew disease might be transmitted by seeds [ 10 , 57 ] and because the residue of active compounds of fungicides has been found in cucumber fruit [ 58 , 59 ]. As the chemicals were detected in the cucumber fruit and there is no information about the effect of fungicides on seed germination, presowing seed treatment was applied.…”

Cucumber is one of the most commonly produced vegetable crops. The greatest economic losses in the yields of these crops have resulted from fungal infections—powdery mildew and downy mildew. The action of fungicides not only affects the fungi, but can also lead to metabolic disorders in plants. However, some fungicides have been reported to have positive physiological effects. Our research focused on the action of two commercially available fungicides, Scorpion 325 SC and Magnicur Finito 687,5 SC, on plant metabolism. Two approaches were used to check the effect of the fungicides at the early stage of plant development when metabolic changes occur most dynamically: spraying on the leaves of cucumber seedlings and presowing seed treatment. The application of the fungicide formulation as a presowing seed treatment caused perturbations in the phytase activity, leading to disorders in the energetic status of the germinating seeds. In addition, the tested preparations changed the morphology of the germinating seeds, limiting the growth of the stem. Furthermore, the application of the tested fungicides on seedlings also showed a disruption in the energetic status and in the antioxidative system. Therefore, the use of pesticides as agents causes a “green effect” and requires a much deeper understanding of plant metabolism.

“…Since then, it has been widely used as a soil drench against Phytophthora and Pythium diseases of various crops, including tobacco (Englander, Merlino, & McGuire, 1980; Rapp & Richter, 1982; Reilly, 1980). Propamocarb hydrochloride [propyl 3‐(dimethyl‐amino) propylcarbamate hydrochloride] has been shown to be efficacious in controlling downy mildew and blight in tomato, potato, cabbage, and pepper (Abd‐Alrahman & Almaz, 2012). Because it has no adverse effects on beneficial microorganisms, propamocarb has been considered a good component of integrated pest management programs (May & Kimati, 2000).…”

“…In cured tobacco, the presence of pesticide residues in leaves could decrease the quality of the cigarette product (Li et al., 2015). Recently, major scientific progresses have been made in understanding the physiological mechanisms of pesticide residues (Abd‐Alrahman & Almaz, 2012; Wu et al., 2013). However, the effects of fungicide residues on the physiological metabolism of tobacco leaves are not yet known.…”

Propamocarb hydrochloride is a systemic fungicide used against Pythium and Phytophthora as well as other diseases in tobacco. This study aimed to understand the response of tobacco to propamocarb hydrochloride treatment at the transcriptome and metabolome levels. Transcriptomic and metabolomic analyses were conducted on tobacco leaves treated with or without propamocarb hydrochloride to identify differentially expressed genes (DEGs) and differential metabolites, which were used for further functional enrichment analyses. In all, 1364 to 2497 DEGs and 34 differential metabolites were identified in different comparable groups. The DEGs were significantly involved in functions related to photosynthesis and valine, leucine, and isoleucine degradation. Differential metabolites were mainly associated with arginine and proline metabolism (1,3-diaminopropane; 4-aminobutyric acid; and N-(omega)hydroxyarginine) and glycerophospholipid metabolism (lysoPC(16:0), phosphorylcholine, and triethanolamine). Our study identified differential genes and metabolites that were associated with the response of tobacco leaves to propamocarb hydrochloride. Propamocarb hydrochloride could influence the photosynthesis, amino acid metabolism, and glycerophospholipid metabolism of tobacco leaves.

“…Quick, Easy, Cheap, Effective, Rugged and Safe (QuEChERS) is a method first introduced by Anastassiades et al (2003) for the monitoring of pesticide multi-residues in fruits and vegetables. This method is particularly popular for pesticide residues determination in various kind of food matrices dueing to its low time-consuming and reduced glassware and organic solvent usage (Abd-Alrahman and Almaz 2012;Urvashi et al 2012). Now the QuEChERS method has been the Official Method of AOAC International (Lehotay 2007).…”

The dissipation and residues of bromothalonil in apple and soil under field condition were analyzed by QuEChERS (quick, easy, cheap, effective, rugged and safe) combined with gas chromatography-mass spectrometer method. The recoveries were ranged from 80.8 % to 106 % with coefficient variation for repeatability ranged from 3.08 % to 7.09 % at fortification levels of 0.02, 0.04 and 0.2 mg/kg in apple and soil. The limit of quantification of the method was 0.31 lg/kg. The dissipation rates of bromothalonil followed the first-order kinetics and the halflives were from 3.61 to 3.98 days in apple and from 4.65 to 9.29 days in soil. In apple, the terminal residues of bromothalonil were below the China maximum residue limit (0.2 mg/kg) after 7 days of application. This work contributed to provide the basic information for a safe usage of bromothalonil in apple orchard and preventing health problem from consumers in China.
