“…The standardized regression coefficient with an order of OM (0.73) > clay (0.47) > CEC (0.24) indicated that OM was the main factor affecting the adsorption of cyantraniliprole, followed by clay and CEC. Similarly, Kolupaeva et al also found that K f was closely correlated with the content of organic carbon and clay …”

Cyantraniliprole uptake, translocation, and distribution in wheat plants grown in hydroponics and soil conditions were investigated. The hydroponics experiment indicated that cyantraniliprole was prone to be absorbed by wheat roots mainly through the apoplastic pathway and predominately distributed in the cell-soluble fraction (81.4–83.6%) and ultimately transferred upward to leaves (TFleave/stem = 4.84 > TFstem/root = 0.67). In wheat-soil systems, the uptake of cyantraniliprole was similar to that in hydroponics. The accumulation of cyantraniliprole in wheat tissues was mainly affected by the content of soil organic matter and clay, resulting in the increased adsorption of cyantraniliprole onto soils (R 2 > 0.991, P < 0.01), and was positively related to the concentration of cyantraniliprole in soil pore water (R 2 > 0.991, P < 0.001). Besides, the absorption of cyantraniliprole by wheat was predicted well by the partition-limited model. These results increased our understanding of the absorption and accumulation of cyantraniliprole in wheat and were also helpful for guiding the practical application and risk evaluation of cyantraniliprole.

The article discusses issues related to the development of pesticide modeling in the environment and its use in order to regulate the circulation of pesticides. As the study of the literature and the author's experience in using mathematical models shows, the main problem and source of errors in modeling is the quality of the input data for the soil block of the model, as well as those characterizing the properties of the pesticide. Using the results of a carefully conducted lysimetric experiment to study the migration of cyantraniliprole outside the soil profile, as well as auxiliary studies, the influence of hydrodynamic dispersion on the behavior of the insecticide and the results of modeling is shown. The parameters of its non-equilibrium sorption by the soil were calculated according to the data of the laboratory experiment investigating the dynamics of decomposition of cyantraniliprole. The article confirms the need to take these processes into account when modeling the transport of pesticides.
