Extraction Method for Determining Florpyrauxifen-benzyl Herbicide in Soil

“…This herbicide was authorized in Brazil in 2019 2 to be used to combat weeds in rice crops, but also in other crops such as soybeans, cotton, corn, sorghum and sunflower, which may generally be cultivated after rice is harvested. [6][7][8][9] The toxicity of this compound to humans and the environment has been the objective of studies in Brazil and in other countries. [10][11][12] Therefore, the insertion of this active ingredient in the environment must be monitored in detail, as the use of this product may cause episodes of environmental and human contamination, and its impacts are still poorly studied.…”

“…5,10,13,14 These characteristics are very favorable for contamination and accumulation in soils, plants, as well as entering the food chain, since some rice varieties have been cultivated in highly irrigated soils. 8 Therefore, with this broad study, we intend to optimize and validate methodologies for extracting florpyrauxifen-benzyl in soil. Due to its recent insertion in agriculture, reports on the extraction method for determining this herbicide in soil samples are rare.…”
