Effects of temperature on the dissipation of total- and water-extractable pesticides in Japanese soils

Autor: Takashi Iwafune, Yutaka Motoki, Keiya Inao, Nobuyasu Seike

Publikováno v: J Pestic Sci

We investigated the dissipation of 27 pesticides in five Japanese soils at three temperatures and the variability of activation energies (E(a)). The dissipation of total pesticides extracted sequentially using water and acetone was fitted to a single

Improvement and application of the PCPF-1@SWAT2012 model for predicting pesticide transport: a case study of the Sakura River watershed

Autor: Julien Boulange, Le Hoang Tu, Takashi Iwafune, Ishwar Chandra Yadav, Hirozumi Watanabe

Publikováno v: Pest Management Science. 74:2520-2529

BACKGROUND The Soil and Water Assessment Tool combined with Pesticide Concentration in Paddy Field (PCPF-1@SWAT) model was previously developed to simulate the fate and transport of rice pesticides in watersheds. However, the current model is deficie

Publikováno v: SC10201904050001
NARO成果DBa-BR-許可制

We performed uptake experiments with 12 different organic chemicals using 16 plant species and determined differences in the ability of plant species to take up and translocate these chemicals. There were differences among the plant species in the sh

We investigated the behavior of isoprothiolane and fipronil after nursery-box application and that of isoprothiolane after submerged application in an experimental paddy field. The concentrations of the pesticides and their metabolites were monitored
