Abstract. Photosystem II (PS II) pesticides, recognised as a threat to ecological health, were targeted for reduction in sugarcane farming the Great Barrier Reef (GBR) catchments. Alternative herbicides, non-PS herbicides (including glyphosate, paraquat, 2,4-D, imazapic, isoxaflutole, metolachlor, and S-metolachlor), continue be used these However, potential fate, transport, off-site environmental effects of with respect their usage scheme, local rainfall patterns, infiltration dynamics, has not been investigated previously. A vadose zone monitoring system, instrumented beneath land GBR catchment, was applied real time tracing pesticide migration across unsaturated zone, past root during 2017–2019.The regularly pesticides (fluroxypyr isoxaflutole), exhibited substantial through zone. Within one month after application fluroxypyr, it leached 2.87 m depth declining concentrations depth. Isoxaflutole, which yearly, found only once, November 2018, at 3.28 soil profile.

The results show no evidence any bores end study, indicating ultimate degradation within before reaching groundwater.

Pesticides are intensely used in the agricultural sector worldwide including smallholder farming. Poor pesticide use practices this agronomic setting well documented and may impair quality of water resources. However, empirical data on occurrence bodies tropical agriculture is scarce. Many available focusing apolar organochlorine compounds which globally banned. We address gap by studying a broad range more modern pesticides an watershed Uganda. During 2.5 months rainy season 2017, three passive sampler systems were deployed at five locations River Mayanja to collect 14 days composite samples. Grab samples taken from drinking In these samples, 27 out 265 organic 60 transformation products detected. resources, we detected eight two insecticide low concentrations between 1 50 ng/L. Also, small streams open fetch ponds, generally with few exceptions for herbicide 2,4-D fungicide carbendazim exceeding ug/L. The widespread chlorpyrifos posed largest risk macroinvertebrates. extensive detection compound its product 3,4,5-trichloro-2-pyridinol was unexpected called better understanding fate pesticide.
