J Environ Sci Health B. 2023 Jun 22:1-12. doi: 10.1080/03601234.2023.2226586. Online ahead of print.ABSTRACTGlyphosate application, even in low doses, changes the metabolism of crops. This research aimed to evaluate the effects of glyphosate low doses and sowing season on metabolic changes of early-cycle common beans. Two experiments were conducted in the field, one in the winter season and one in the wet season. The experimental design was a randomized complete block design consisting of the application of glyphosate low doses [0.0, 1.8, 7.2, 12.0, 36.0, 54.0, and 108.0 g acid equivalent (a.e.) ha-1] in the phenological s...

Method development and validation in the curry leaf matrix employing advanced mass spectrometry: quantitative screening of 490 multiclass pesticides by buffered ethyl acetate technique
J Environ Sci Health B. 2023 Jun 18:1-17. doi: 10.1080/03601234.2023.2221994. Online ahead of print.ABSTRACTCurry leaf is an evergreen herb with culinary, pharmaceutical, and nutraceutical applications. As pesticide residue in curry leaf has garnered significant regulatory attention in recent years, here we report a reliable method, which was validated for the determination of 265 and 225 pesticides using LC-MS/MS and GC-MS/MS, respectively. At first, the sample was comminuted after adding water (1:2). The sample preparation workflow included extraction of 10 g homogenized sample with 10 mL ethyl acetate (+1% acetic acid),...

Screening bacterial isolates for biocontrol of sheath blight in rice plants
The objective was to screen bacterial isolates as an antagonist to R. solani and identify the most efficient ones as sheath blight suppressors under greenhouse conditions. Two assays (E1 and E2) were performed in a completely randomized design with three replications. E1 tested 21 bacterial isolates antagonists to R. solani in vitro. E2 was conducted under greenhouse conditions, with rice cultivar BRS Pampeira sown in plastic pots (7 kg) containing fertilized soil. Sixty old plants were inoculated with a segment of a toothpick containing fragments of R. solani, followed by spray inoculation of a bacterial suspension (108 C...

Extraction method for determining dinotefuran insecticide in water samples
J Environ Sci Health B. 2023 Jun 12:1-9. doi: 10.1080/03601234.2023.2220638. Online ahead of print.ABSTRACTDinotefuran is a compound belonging to the third generation of nicotinoid insecticides, and has been effective in combating pests that are resistant to conventional insecticides, such as organophosphates, carbamates, and pyrethroids. This molecule presents high-water solubility (39,830 mg L-1 at 25 °C) compared to other pesticides, which facilitates its drag and leaching to lower soil layers. Therefore, the present study aimed to optimize and validate liquid-liquid extraction with low temperature purification (LLE-LT...

Non-destructive estimation of weed response to bleaching herbicides by Raman spectroscopy
J Environ Sci Health B. 2023 Jun 8:1-12. doi: 10.1080/03601234.2023.2220645. Online ahead of print.ABSTRACTThe aim of our study was to evaluate the use of Raman spectroscopy for pre-diagnostic estimation of weed response to bleaching herbicides. Model plants were Chenopodium album and Abutilon theophrasti treated with mesotrione (120 g a.i. ha-1). Raman single-point measurements were taken 1, 2, 3, and 7 days after herbicide application from different points on the leaves. Principal component analysis (PCA) was carried out on data normalized by the highest intensity band at 1522 cm-1 and using spectral region from 950 to 1...
